Description

페놀수지발포체{Phenol resin foam}Phenolic resin foam

본 발명은 페놀수지발포체에 관한 것으로서, 보다 상세하게는 휨강도가 상승되고 다른 소재들과의 접착성 등이 우수하며, 작업시 또는 화재시 연소되면서 발생되는 악취와 유독가스를 감소시킬 수 있도록 구성되어 건축용 내장재로서의 제품성이 우수한 새로운 구성의 페놀수지발포체에 관한 것이다.The present invention relates to a phenolic resin foam, more specifically, the bending strength is increased and excellent adhesion to other materials, and is configured to reduce the odor and toxic gases generated during combustion during work or fire The present invention relates to a phenolic resin foam having a new composition with excellent productability as a building interior material.

일반적으로 화재시에는 화염에 타서 사망하는 경우보다, 실내의 내장재나 기타 물품들이 타면서 발생되는 유독가스에 의해 질식되어 사망하는 경우가 더 많다. 따라서 건축물의 내장재에 대한 엄격한 규제가 이루어지고 있는데, 내장재는 난연성이 우수하여야 하는 것은 물론이며, 저발연성이여야 한다.In general, a fire is more likely to be suffocated by toxic gases produced by burning interior linings and other items than by burning. Therefore, strict regulations on the interior materials of buildings are being made. The interior materials must be of high flame retardancy and of course, low smoke.

한편, 페놀수지발포체는 난연성이 우수할 뿐만 아니라 저발연성이기 때문에 건축용 내장제로 주로 사용된다. 그러나 페놀수지발포체는 푸석푸석하고 표면이 잘 부스러지며, 휨강도가 약하여 적은 외력에 의해서도 쉽게 부러지는 단점이 있다. 또한, 페놀수지발포체는 건축용 내장재 등으로 사용하기 위해 표면에 마감보드나또는 기타 PP/PE 등의 합성수지시트 등을 부착하면, 부착상태가 유지되지 않고 페놀수지발포체의 표면이 분말형태로 부스러지면서 부착된 시트 등이 쉽게 떨어지는 단점이 있다.On the other hand, phenolic resin foam is not only excellent in flame retardancy but also low smoke, it is mainly used as a building interior agent. However, the phenolic resin foam has a disadvantage that it is crumbly, the surface is brittle, and the bending strength is weak so that it is easily broken by a small external force. In addition, when phenolic resin foam is attached to the surface of finishing boards or other synthetic resin sheets such as PP / PE, etc. for use as building interior materials, the adhesion state is not maintained and the surface of the phenolic resin foam is broken in powder form. There is a disadvantage that the sheet is easily dropped.

그리고 페놀수지는 페놀과 포름알데히드의 반응에 의해 제조되는데, 페놀수지에는 미처 반응에 참여하지 못한 페놀이나 포름알데히드가 함유되어 있다. 따라서 페놀수지에서는 페놀이나 포름알데히드에 의한 악취가 발생되는데, 이 악취 때문에 작업자들이 작업을 꺼리기도 할 뿐만 아니라 작업의욕이 저하되어 생산성이 감소되는 원인이 되었다.The phenol resin is produced by the reaction between phenol and formaldehyde, which contains phenol or formaldehyde that did not participate in the reaction. Therefore, in the phenol resin, odor caused by phenol or formaldehyde is generated. This odor not only causes workers to be reluctant to work, but also causes a decrease in work motivation, which causes a decrease in productivity.

본 발명은 상기의 문제점을 해결하기 위한 것으로서, 본 발명의 목적은 휨강도가 상승되고 다른 소재들과의 접착성이 등이 개선되며 작업시 발생되는 악취 등이 제거됨은 물론이고, 화재시 발포체가 연소되면서 발생되는 악취와 유독가스의 배출량이 현저하게 감소되도록 구성되어 건축용 내장제로서의 제품성이 우수한 새로운 구성의 페놀수지발포체를 제공하는 것이다.The present invention is to solve the above problems, an object of the present invention is to increase the flexural strength, improve the adhesiveness with other materials and the like, the odor generated during the work is removed, as well as the foam is burned during fire It is to provide a new composition of phenolic resin foam with excellent productability as a building interior agent as it is configured to significantly reduce the emissions of odor and toxic gases generated as a result.

본 발명에 따르면, 페놀수지와, 계면활성제, 발포제, 경화제 등을 혼합하고 이를 발포시켜 제조되는 페놀수지발포체에 있어서, 상기 페놀수지발포체는 상기 성분들 외에 PEG가 페놀수지 100중량부에 대해 8~30중량부로 혼합되어 발포처리된 것을 특징으로 하는 페놀수지발포체가 제공된다.According to the present invention, in the phenolic resin foam prepared by mixing a phenol resin, a surfactant, a foaming agent, a curing agent and the like and foaming the phenolic resin foam, the phenolic resin foamed body is PEG 8 ~ 100 parts by weight based on 100 parts by weight of the phenolic resin It is mixed with 30 parts by weight is provided with a phenolic resin foam characterized in that the foaming treatment.

본 발명의 다른 특징에 따르면, 페놀수지와, 계면활성제, 발포제, 경화제 등을 혼합하고 이를 발포시켜 제조되는 페놀수지발포체에 있어서, 상기 페놀수지발포체는 상기 성분들 외에 MDI가 페놀수지 100중량부에 대해 1~6중량부로 혼합되어 발포처리된 것을 특징으로 하는 페놀수지발포체가 제공된다.According to another feature of the present invention, in the phenolic resin foam prepared by mixing a phenol resin, a surfactant, a foaming agent, a curing agent and the like and foaming, the phenolic resin foam body is MDI in addition to the components 100 parts by weight of phenolic resin It is mixed with 1 to 6 parts by weight with respect to the phenol resin foam is characterized in that the foaming treatment.

본 발명의 또 다른 특징에 따르면, 페놀수지와, 계면활성제, 발포제, 경화제 등을 혼합하고 이를 발포시켜 제조되는 페놀수지발포체에 있어서, 상기 페놀수지발포체는 상기 성분들 외에 PEG와 MDI 중에서 적어도 하나가 추가로 혼합되고, 이에 활성탄분말이 더 혼합되며, 상기 PEG와 MDI와 활성탄분말은 페놀수지 100중량부에 대해 각각 8~30중량부, 1~6중량부, 1~30중량부로 혼합된 것을 특징으로 하는 페놀수지발포체가 제공된다.According to another feature of the present invention, in the phenolic resin foam prepared by mixing and foaming a phenolic resin, a surfactant, a blowing agent, a curing agent and the like, the phenolic resin foam is at least one of PEG and MDI in addition to the above components The mixture is further mixed, activated carbon powder is further mixed, and the PEG, MDI and activated carbon powder are mixed in an amount of 8 to 30 parts by weight, 1 to 6 parts by weight, and 1 to 30 parts by weight with respect to 100 parts by weight of the phenol resin, respectively. A phenol resin foam is provided.

이하, 본 발명을 더욱 구체적으로 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail.

본 발명은 페놀수지와, 이 페놀수지의 발포시 일반적으로 사용되는 계면활성제, 발포제, 경화제 등을 혼합하고, 이에 PEG, 활성탄 등을 추가로 혼합하여 발포처리된 페놀수지발포체에 관한 것이다. 상기 계면활성제와, 발포제, 경화제는 일반적으로 상용되는 약품 중에서 적절하게 선택된다.The present invention relates to a phenol resin foam that is foamed by mixing a phenol resin and a surfactant, a blowing agent, a curing agent, and the like, which are generally used in the foaming of the phenol resin, and further mixing PEG, activated carbon, and the like. The surfactant, the blowing agent and the curing agent are generally appropriately selected from among commonly used drugs.

한편, 본 발명에서는 상기 약품들에도 PEG(Polyethylene glycol)가 추가로혼합된다. 이 PEG는 페놀수지발포체에 탄성을 부여하여 발포체의 휨강도를 증가시키며, 원료의 혼합시 원료들의 점도를 낮추고, 경화 후 발포체가 푸석푸석하여 표면에서 분말이 떨어지는 문제점들을 제거하며 발포체의 접착성을 증가시킨다. 이러한 PEG는 페놀수지 100중량부에 대해 8~30중량부로 사용되는데, PEG가 30중량부 이상이면, 오히려 상품의 휨강도가 저하되고, 발포체의 경화속도가 저하될 뿐만 아니라 난연성도 저하된다. 그리고 PEG가 8중량부 이하이면 여전히 발포체의 표면에서 분말이 떨어지게 되고 접착성이 낮아 발포체의 표면에 부착된 시트 등이 박리된다. 필요에 따라서는 PVC, EPS, Urea-formaldehyde 로 PEG를 대체할 수 있다.Meanwhile, in the present invention, polyethylene glycol (PEG) is further mixed in the above drugs. The PEG gives elasticity to the phenolic resin foam, which increases the bending strength of the foam, lowers the viscosity of the raw materials when mixing the raw materials, eliminates the problem of powder falling off the surface after curing, and increases the adhesiveness of the foam. Let's do it. Such PEG is used in an amount of 8 to 30 parts by weight based on 100 parts by weight of phenolic resin. If PEG is 30 parts by weight or more, the flexural strength of the product is lowered, the curing rate of the foam is lowered, and the flame retardancy is also lowered. And if the PEG is 8 parts by weight or less, the powder still falls on the surface of the foam and the adhesiveness is low, the sheet or the like attached to the surface of the foam is peeled off. If necessary, PVC, EPS, or urea-formaldehyde can be substituted for PEG.

그리고 활성탄분말이 추가로 혼합된다. 일반적으로 페놀수지에는 미처 반응에 참여하지 못한 페놀과 포름알데히드가 함유되어 있으며, 이러한 페놀과 포름알데히드에 의해 페놀수지에서는 유독한 냄새가 난다. 이와 같은 이유로 작업시 발생되는 악취나 유독가스 등이 활성탄에 흡착되어 감소된다. 뿐만 아니라 화재시에 발포체가 타면서 발생되는 악취와 일산화타소 등의 유독가스 또한 활성탄에 의해 흡착되어 감소된다. 이러한 활성탄은 페놀수지 100중량부에 대해 1~30중량부 사용되는데, 활성탄이 30중량부 이상이면 활성탄에 의한 냄새와 유독가스 흡수효과는 상승되나 활성탄분말이 발포체에서 탈리될 가능성이 있으므로 바람직하지 않다. 필요에 따라서는 크레이를 추가로 혼합할 수도 있는데, 이때에는 발포체의 강도가 상승될 뿐만 아니라 난연성도 증가된다.And activated carbon powder is further mixed. In general, phenolic resins contain phenol and formaldehyde that did not participate in the reaction, and the phenolic and aldehyde form a toxic smell from the phenolic resin. For this reason, odors and toxic gases generated during operation are absorbed and reduced by the activated carbon. In addition, the odor generated by the burning of the foam during the fire and toxic gases such as titanium monoxide are also absorbed and reduced by the activated carbon. Such activated carbon is used in an amount of 1 to 30 parts by weight based on 100 parts by weight of phenolic resin. If activated carbon is 30 parts by weight or more, the odor and toxic gas absorption effect by activated carbon are increased, but activated carbon powder may be released from the foam, which is not preferable. . If necessary, the cray may be further mixed, which not only increases the strength of the foam but also increases the flame retardancy.

한편, 필요에 따라서는 페놀수지와, 계면활성제, 발포제, 경화제를 혼합하고 이에 MDI(Methylene diphenyl isocyanate)를 추가로 혼합하여 발포시킬 수 있다.이와 같이 MDI를 혼합하면, 전술한 바와 같이 페놀수지에 함유되어 있는 페놀과 포름알데히드가 MDI와 반응하므로 페놀과 포름알데히드에 의한 악취 등이 제거된다. 따라서 페놀수지의 발포시 MDI와 함께 활성탄을 혼합하여 사용하면, 전술한 바와 같이 활성탄에 의해 악취와 유독가스가 물리적으로 흡착되어 제거됨과 더불어, MDI에 의해서는 악취의 원인이 되는 페놀과 포름알데히드가 화학적으로 반응되어 제거되므로 악취와 유독가스의 제거율이 현저하게 상승된다.If necessary, a phenol resin, a surfactant, a blowing agent, and a curing agent may be mixed, and MDI (Methylene Diphenyl Isocyanate) may be further mixed and foamed. If MDI is mixed in this way, the phenol resin may be mixed with the phenol resin as described above. Since phenol and formaldehyde contained react with MDI, odors caused by phenol and formaldehyde are removed. Therefore, when activated carbon is mixed with MDI when foaming phenolic resin, as described above, odor and toxic gas are physically adsorbed and removed by activated carbon, and phenol and formaldehyde, which cause odor, are caused by MDI. Chemically reacted and removed, the removal rate of odor and toxic gas is significantly increased.

또한, 상기 MDI를 혼합하면 발포체의 강도가 상승될 뿐만 아니라 발포체의 경화가 촉진된다. 이러한 MDI는 페놀수지 100중량부에 대해 1~6중량부 사용되는데, MDI가 6중량부 이상이면 발포체가 푹푹꺼지는 현상이 나타나며, 발포체의 강도가 저하되고, 난연성이 저하된다. 이때 필요에 따라서는 페놀수지에 PEG와 MDI를 함께 혼합할 수 있다.In addition, mixing the MDI not only increases the strength of the foam but also promotes curing of the foam. The MDI is used 1 to 6 parts by weight based on 100 parts by weight of phenolic resin, but if the MDI is 6 parts by weight or more, the foam is completely blown out, the strength of the foam is lowered, flame retardancy is lowered. At this time, if necessary, PEG and MDI may be mixed together in the phenol resin.

필요에 따라서는 크레이를 혼합할 수도 있다. 이와 같이 크레이를 혼합하면 발포체의 강도가 상승되고, 화재시 불에 타서 발포체가 관통되는 것이 방지되며, 내열성도 증가된다.If necessary, crayfish may be mixed. When the cray is mixed in this way, the strength of the foam is increased, the fire is prevented from penetrating through the fire during the fire, and the heat resistance is also increased.

바람직하게는 본 발명에 의해 페놀수지를 제조하는 경우에는 먼저, 페놀수지와, PEG, 계면활성제, 활성탄 발포제 등을 혼합하여 주용액을 제조하고, 경화제는 별도의 용기에서 물과 혼합하여 둔다. 이때 바람직하게는 페놀수지 100중량부, 계면활성제 2.3중량부, PEG 20중량부, 발포제 14중량부, 활성탄 1중량부, MDI 6중량부, 경화제 10중량부로 혼합한다. 그리고 상기 물에 혼합된 경화제와 액상의 MDI를 상기 페놀수지와 PEG 등이 혼합된 주용액에 혼합하여 발포처리한다.Preferably, when preparing a phenolic resin according to the present invention, first, a main solution is prepared by mixing a phenolic resin with PEG, a surfactant, an activated carbon blowing agent and the like, and the curing agent is mixed with water in a separate container. In this case, preferably, 100 parts by weight of phenol resin, 2.3 parts by weight of surfactant, 20 parts by weight of PEG, 14 parts by weight of blowing agent, 1 part by weight of activated carbon, 6 parts by weight of MDI, and 10 parts by weight of a curing agent are mixed. And the curing agent and the liquid MDI mixed in the water is mixed with the main solution mixed with the phenol resin and PEG and foamed.

이상에서와 같이 본 발명에 의하면, 휨강도가 상승되고 다른 소재들과의 접착성이 등이 개선되며 작업시 발생되는 악취 등이 제거됨은 물론이고, 화재시 발포체가 연소되면서 발생되는 악취와 유독가스의 배출량을 현저하게 감소시킬 수 있어서 건축용 내장재로서의 제품성이 우수한 새로운 구성의 페놀수지발포체가 제공된다. 따라서 본 발명에 의한 페놀수지발포체를 사용하는 경우에는 그 표면에 PP/PE/PET/ABS 등을 적층시킨 다양한 제품들을 제공할 수 있으며, 작업환경이 개선되어 생산성이 향상되므로 제품의 코스트도 저하된다. 특히 화재시 악취와 유독가스의 발생량 자체가 현저하게 감소될 뿐만 아니라 발생된 유독가스 등이 발포체에 함유된 활성탄에 의해 흡착되므로 유독가스에 의해 질식사망율을 저하시킬 수 있는 고품질의 건축용 내장재가 제공된다.As described above, according to the present invention, the bending strength is increased, the adhesion to other materials is improved, and the odor generated during the work is removed, as well as the odor and toxic gas generated when the foam is burned during a fire. Emissions can be significantly reduced, providing a new phenolic resin foam having excellent productability as a building interior material. Therefore, in the case of using the phenolic resin foam according to the present invention can provide a variety of products laminated on the surface of PP / PE / PET / ABS, and the work environment is improved, productivity is improved, so the cost of the product is also lowered . In particular, the amount of odor and toxic gas generated by fire is significantly reduced, and the generated toxic gas is absorbed by activated carbon contained in the foam, thereby providing a high-quality building interior material that can reduce the asphyxiation mortality rate due to toxic gas. .
