〔産業上の利用分野〕
本発明は、主として建築物の窓まわり、天井や配管など
の結露発生部分に施工することにより、防結露性能を有
する被覆組成物に関するものである。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a coating composition that has anti-condensation properties when applied to areas where condensation occurs, such as around windows, ceilings and pipes of buildings. be.
現在、結露防止対策として、換気扇により通風をよくし
たり、グラスウール、発泡スチロール等の断熱材を天井
や壁面内に設けたりしている。Currently, as measures to prevent condensation, ventilation fans are used to improve ventilation, and insulation materials such as glass wool and styrofoam are installed in ceilings and walls.
しかし、断熱層を設けた場合、断熱材の裏面温度が断熱
材を施す前よりも下がるため、断熱材を透過した水蒸気
が裏面で結露し、いわゆる内部結露が発生し、かびの発
生の温床となったり、建築物の下地の劣化を促進するこ
とがある。However, when a heat insulating layer is provided, the temperature on the back side of the heat insulating material is lower than before the heat insulating material is applied, so water vapor that has passed through the heat insulating material condenses on the back surface, resulting in so-called internal condensation, which becomes a breeding ground for mold growth. It may cause damage or accelerate the deterioration of the foundation of the building.

吸収すると水が保持され、保持した水を放出にくい性質
があり、しかも吸水によりその重量で脱落するという欠
点があった。On the other hand, there has traditionally been a fiber wall that can be applied to walls, but the fiber wall apparently absorbs the condensation water on the surface by absorbing the condensation water. When it absorbs water, it retains water and has the property of being difficult to release the retained water, and has the disadvantage that it falls off due to its weight as it absorbs water.

井材に留まっている。As a well-known method, it is often said that coatings made from lightweight aggregates with high water absorption properties, such as vermiculite and perlite, with synthetic resin emulsions and other extender pigments as necessary, have high moisture absorption properties. Are known. Although this method can easily coat surfaces with complex shapes and has an aesthetic appearance as a finishing layer, its use is limited to ceiling materials due to its adhesion.

が珪藻土の表面の細孔を充填してしまい、防結異性を著
しく低下させてしまう。In terms of anti-condensation performance, a coating material containing synthetic resin emulsion and diatomaceous earth as its main components has been proposed (Japanese Unexamined Patent Publication No. 57-151661). , about 20-30 microns in diameter and cylindrical in shape. On the other hand, when using an emulsion with an average particle size of 0.1 to 0.5 microns, the emulsion enters from the mouth of the cylinder, which is about 1 to 2 microns, and fills the pores on the surface of diatomaceous earth. This results in a significant decrease in anti-crosslinking properties.

い。The porous inorganic powder, which is a crystalline form of calcium silicate used in the present invention, has a porous structure and a pore size of 0.01.
~1 micron, and since the pores are smaller than the emulsion particles, the emulsion has an extremely high ability to absorb condensed water without penetrating into the pores and blocking them.

。In the present invention, a porous inorganic powder which is a crystalline form of calcium silicate is used, and when the temperature of the wall surface of the coating film is above the dew point, this porous portion absorbs water and humidity, but when the temperature is below the dew point, the porous inorganic powder becomes porous. On the other hand, the synthetic resin emulsion used in the present invention is one in which liquid particles are dispersed as colloidal particles in a liquid to form an emulsion. In addition to oil-in-water type synthetic resin emulsions known as synthetic resin emulsions, NA has been used in many fields in recent years.
D (non-aqueous dispersion) can be used.

Any composition commonly used for paints may be used, such as a mixture of more than one species or a copolymer.

３０重量部であることが望ましい。In the present invention, the solid content of the synthetic resin emulsion is 10
It is an essential condition that 50 to 250 parts by weight of porous inorganic powder, which is a calcium silicate crystal, is blended to 0 parts by weight, and more preferably 80 to 2 parts by weight.
The amount is preferably 30 parts by weight.

する。Porous inorganic powder which is calcium silicate crystal is 50
When the amount is less than parts by weight, the amount of emulsion becomes relatively large, and the porous inorganic powder, which is calcium silicate crystal, is coated with the emulsion, resulting in a decrease in water absorption performance and a decrease in anti-condensation performance. If the amount of porous inorganic powder, which is calcium silicate crystals, is 250 parts or more, the amount of emulsion will be relatively small, and the coating may crack or peel off from the base after drying.

Manufactured by Toho Perlite 91 Product name: "Pearlite FJ" Table 2 Test items and methods [Effects of the invention] When the outside air in contact with the membrane is above the dew point, it absorbs water and humidity, and when it is below the dew point, it releases the moisture absorbed within the coating, which not only prevents condensation inside the building, but also has a humidity control effect. Therefore, when the coating composition according to the present invention is applied inside a building, it is considered that a comfortable life can be enjoyed.Also, as shown in the examples, the anti-condensation effect is higher than that of conventional anti-condensation paints. It has excellent performance not only in terms of adhesive strength but also in adhesive strength, and we are confident that it will have a wide range of applicability.
以上that's all
