Description

Technical field

The technical solution relates to the production of a mixture intended for building industry containing cellulose using both as a building material of high thermal insulation properties with reduced weight but mainly as a basic mixture for the production of prefabricated elements respectively. thermal insulating materials using non-recoverable waste.

BACKGROUND OF THE INVENTION

Until now, classical prefabricated products containing a greater or lesser amount of cement-water mixture have been used in the construction industry. These products, after curing, have a relatively high weight, since the mixture used is particularly rigid. In the case of bricks or blocks used in foundations, the weight still does not constitute a significant role, only manual labor is relatively laborious with them. For tile and roof coverings, high weight is a major obstacle due to possible structural damage. In some technical solutions crushed or ground polystyrene was added to the concrete mixture. The use of waste glass in the form of granules and the use of sheep wool for insulation is also known. These disadvantages were partially overcome by the cellulose-containing concrete mixture according to SK Utility Model no. 3976. However, its use was limited as it did not address the possibility of heat treatment for special purposes such as sound insulation or heat-insulating materials. Also, the machining of the prefabricated components used was difficult.

The essence of the technical solution

The disadvantages of the prior art are largely eliminated by a utility model containing a cellulose-containing construction composition comprising components in an optimal ratio, which consists of at least 5% by volume of cellulose mixture and at most 95% by volume of cement with sand and industrial dry matter preferably 10 % by volume of the cellulosic mixture and 90% by volume of the cement with sand and industrial dry matter, or preferably 90% by volume of the cellulosic mixture and 10% by volume of cement with sand and industrial dry matter, the cellulosic mixture being 100% by volume of pulp fibers or recycled paper; or at least 30% by volume of pulp fibers or recycled paper with an addition of 5 to 10% by volume of water glass and / or 2 to 15% by volume of natural resin and / or 5 to 25% by volume of kaolin and / or 5 to 20% by volume chalk.

The vacuum curing composition can be heat treated in the range of 0 to 100 ° C.

The pulp fibers are obtained from shredded waste wood, possibly torn or ground waste paper, which is poured in a 1: 1 ratio of water in the prepared container and left to act for about 7 to 24 hours with occasional stirring. Subsequently, water glass and / or natural resin and / or kaolin and / or chalk are added to the prepared mass in a specified ratio. The individual components may be mixed individually or all together with the cellulose as desired for the purpose of using the mixture formed. Once the wood or paper has been completely dissolved into the pulp mixture, the prepared cellulose mixture is added in a specified ratio to the cement / sand mixture with industrial dry matter to be used in the construction industry.

Its advantage is that the pulp fibers, which are obtained from waste wood or waste paper, act as a plasticizer for building mixtures, reducing the cracking of the precast products, creating thermal insulation and increasing the flexibility of the individual products. The use of water glass, natural resin, kaolin or chalk allows heat treatment and vacuum curing. Compared with previous materials, the mixture has the advantages of a wide assortment in the creation of building materials, various heat-insulating materials at the required flexibility, internal stress, fire resistance, while also providing sound insulation.

Examples of technical solution

Depending on the usable volume, a certain amount of cellulosic mixture, for example 1: 1 waste paper with water, is introduced into the mixer and allowed to interact for about 7 to 24 hours. Once the paper has dissolved to a slurry, it is used in the manufacture of individual precasts from the mixture as follows:

To make gypsum boards, 5-25% by volume of kaolin are added to the cellulosic mixture.

5-10% by volume of water glass is added to the cellulosic mixture to produce waterproofing boards and linings.

In order to produce heat-insulating bricks or blocks, 2 to 15% by volume of natural resin and 5 to 20% by volume of chalk are added to the cellulosic mixture. Natural resin provides us with flexibility and chalk fineness when machining used precast products.

The prepared selected cellulose mixture is then mixed with 10 to 90% by volume of cement with 5 sand and industrial dry matter.

Appropriate prefabricated components can then be used in the building industry after the technological treatment, whereby the mixture used allows not only vacuum curing but also heat treatment at 0 to 100 ° C.

Industrial usability

The mixture according to the technical solution is primarily intended for construction.
