Gelatinizer

Abstract

The invention relates to a gelatinizer including the following components, by weight: 30-350 parts of magnesium- and aluminum-rich silicate (Mg5Si8O20(OH)2(OH2)4.4H2O), 80-150 parts of high-activity aluminum silicate, 5-15 parts of boric acid (H3BO3), 5-15 parts of citric acid (C6H8O7), 2-15 parts of phosphoric acid (H3PO4), 5-10 parts of silicon sol (SiO2.nH2O), 1-3 parts of a siloxane waterproof agent, 800-1200 parts of light calcined magnesium oxide, 300-500 parts of magnesium chloride hexahydrate, 80-120 parts of magnesium sulfate heptahydrate, and 400-600 parts of water. The gelatinizer, on the basis of maintaining the technical indices, such as fireproof performance, waterproof performance and the like, is free of formaldehyde when being used for cementing and adhering various building decorative materials, so that the gelatinizer increases utilization rate of house, provides a green and environment-friendly living environment, and is beneficial to body health of residents.

Description

technical field [0001] The invention relates to a building material, in particular to a gelling agent widely used for cementing and bonding building decorative boards. Background technique [0002] So far, the adhesives used for woody and herbaceous straw fibers all use the known two types of adhesives, trialdehyde glue, urea-formaldehyde, phenolic formaldehyde, melamine formal and polymeric isocyanate. The former of these two types of adhesives contains formaldehyde, Urea-formaldehyde glue has poor incombustibility and water resistance, so it cannot be applied to hot-pressed straw boards, and the latter is expensive so that it cannot be popularized and applied. Especially when using the above boards solidified with formaldehyde-containing gelling agents to decorate houses and furniture made with the above-mentioned boards solidified with formaldehyde-containing gelling agents, it is necessary to leave the houses vacant for several months to make the formaldehyde volatilize ...

Problems solved by technology

[0002] So far, the adhesives used for woody and herbaceous straw fibers all adopt these two types of adhesives known as trialdehyde glue, urea-formaldehyde, phenolic formaldehyde, melamine formal and polymeric isocyanate. The former of the above-mentioned two types of adhesives contains formaldehyde, Urea-formaldehyde glue has poor incombustibility and water resistance, so it cannot be applied to hot-pressed straw boards, and the latter is expensive so that it cannot be popularized and applied

Especially when using the above boards solidified with formaldehyde-containing gelling agents to decorate houses and furniture made of the above-mentioned boards solidified with formaldehyde-containing gelling agents, it is necessary to leave the houses vacant for several months to make the formaldehyde volatilize as much as possible before moving in. This reduces the utilization rate of the house, and it is difficult for formaldehyde to volatilize completely, which seriously endangers the health of the residents.
