Preparation method of environment-friendly fireproof interior wall material

Abstract

The invention discloses a preparation method of an environment-friendly fireproof interior wall material. The method is characterized in that: reacting magnesium oxide, magnesium sulfate and water forshaping, adopting citric acid monohydrate, sodium citrate, calcium phosphate and calcium stearate as assistants, taking bamboo sawdust, bentonite, coal ash, talcum powder and the like as auxiliary filling materials to prepare slurry, combining and distributing medium-alkali or low-alkali glass fiber grey cloth and non-woven fabric on an upper surface and a lower surface respectively, adding the slurry to the space therebetween, conducting roll forming, and then performing curing and demolding. The used raw materials are safe and environment-friendly, the prepared environment-friendly fireproof interior wall material has formaldehyde emission as low as 0.1ml / L, which is lower than the EU Standards, the board has a fireproof grade A1 and a chlorine ion content as low as 0.07%, the surface is not wet in the curing process, water drops are avoided, namely, the anti-halogen phenomenon is avoided, the moisture resistance is good, the dry shrinkage rate is 0.1%, the wet expansion rate is 0.1%, the size stability of the board is good, the sulfate resistance of the material is good, the etching phenomenon is not likely to happen, the material adhesiveness is good, and coloring is easy.

Description

technical field [0001] The invention belongs to the field of building material preparation, and in particular relates to a preparation method of an environment-friendly fireproof interior wall material. Background technique [0002] Interior wall panels are a kind of decorative building panels commonly used in home decoration. At present, the commonly used interior wall panels are mainly wooden interior wall decoration materials, which are prone to frequent fire accidents and seriously threaten the safety of people's lives and property. Wood-based wood-based panels belong to Flammable materials, the combustion process releases a large amount of heat, spreads quickly, and can also release toxic smoke, so the fire hazard is great; and it is easy to be distorted and deformed during use, and the board surface will change color, pulverize, and crack due to moisture , The adhesion of the board is not good when it is used, and the shedding phenomenon is very serious. Therefore, in...

Problems solved by technology

Not only that, as an interior wall material, it is difficult to meet the requirements of national or industry standards in terms of flexural strength, impact strength, dry shrinkage rate, wet expansion rate, screw holding force, and non-combustibility, which limits the Use of flame retardant board as interior wall material in actual production

At present, the cost of the existing flame-retardant, moisture-proof and environmentally friendly interior wall panels is relatively high, which affects the popularity of interior wall panels. Therefore, people need a flame-retardant, moisture-proof, and environmentally friendly interior wall panels with a relatively simple structure and low cost.
