Problems solved by technology

[0002] Lightweight partition walls are developed with the popularity of high-rise buildings. At present, the commonly used lightweight partition walls are made of cement, expanded perlite, etc., and lined with fiber Made of grid cloth, it is mainly used for non-load-bearing walls inside building structures. Although it solves this technical problem, its strength is also reduced. Therefore, a new type of wall with light weight and high strength is needed

Embodiment 1

[0027] 3) Add 0.5 parts of ammonium persulfate to the slurry obtained in step 2), and continue to mix and react for 5 hours;

[0028] 4) Mix 30 parts by weight of sand, 20 parts by weight of fly ash and 5 parts by weight of cement with the slurry obtained in step 3, and keep stirring the slurry for 30-40 minutes;

[0029] 5) Pour the slurry obtained in step 4) into the wall mold and let it stand for 3 hours;

[0030] 6) Put the mold above into the curing room, gradually raise the temperature at a rate of 5-8°C per hour, maintain at a constant temperature of 50°C for 6 hours, keep at a constant temperature of 80°C for 10 hours, and then dry at a temperature of 120°C for 12 hours;

[0031] 7) Cool down to room temperature gradually at a rate of 5-8°C;

[0032] 8) Demoulding to obtain a lightweight wall.

Abstract

A new type of lightweight wall, produced by the following method: ethyl orthosilicate, methyltriethoxysilane, water and absolute ethanol, under the action of trimethylchlorosilane and polyethylene glycol to generate wet Gel; the added methacrylic acid and styrene are organic monomers, which produce free radical polymerization under the action of crosslinking agent methylene bisacrylamide or diethylene glycol acrylate and initiator ammonium persulfate to form a network Shaped polymer compound, polymer compound and sand and fly ash powder form a solid mosaic structure, so as to achieve high strength; the wall is light in weight and high in strength, and has the functions of sound insulation, heat preservation and fire prevention.

Description

technical field [0001] The invention relates to a building component, in particular to a lightweight wall. Background technique [0002] Lightweight partition walls are developed with the popularization of high-rise buildings. At present, the commonly used lightweight partition walls are made of cement, expanded perlite, etc., and are lined with fiber mesh cloth. They are mainly used for the interior of building structures. Although the non-load-bearing wall solves this technical problem, its strength is also reduced. Therefore, a new type of wall with light weight and high strength is needed. Contents of the invention [0003] The object of the present invention is to provide a lightweight wall body, which is both lightweight and high-strength, and also has a certain sound insulation function, and is an excellent building component. [0004] In order to solve the above problems, the technical scheme adopted in the present invention is as follows: [0005] A novel lig...
