Abstract

The invention discloses a wear-resistant anti-cracking environment-friendly plasterboard which is prepared from the following raw materials in parts by weight: polyvinyl alcohol 8-14 parts, pulverized fuel ash 7-9 parts, old plasterboard powder 35-45 parts, gypsum powder 25-35 parts, anti-cracking fiber 10-14 parts, an initiator 1-3 parts, an antifoamer 1-1.4 parts, a dispersant 2-4 parts, crystalline flake graphite 10-14 parts, starch 5-10 parts, and deionized water 50-70 parts. The plasterboard of the invention has the advantages of high and compression strength, static bending strength, large screw holding capability and breaking resistant elasticity modulus, low heat conductivity coefficient, and has the characteristics of good antibacterial property, mechanical property, anti-electromagnetic radiation property and anti-friction property. Meanwhile, the raw materials of the wear-resistant anti-cracking environment-friendly plasterboard are safe and reliable, environment-friendly and easily-accessible, the cost is low, the process is simple and is easy to operate and realize industrial production, and the process has high practical value and good application prospects.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a wear-resistant, crack-resistant and environmentally friendly gypsum board and a preparation method thereof. Background technique [0002] At present, with the improvement of people's living standards, most family houses are decorated with gypsum boards. Gypsum board is a lightweight, fire-resistant building decoration material, mostly used for indoor ceilings. There are various plate and strip products on the market. Most of the existing gypsum is made of polyvinyl alcohol, glue and water mixed into paste gypsum. The gypsum material of these gypsum boards is a moisture-absorbing material, so in It is used in some indoor environments that generate water vapor and humidity. After a period of use, the plasterboard will loosen and fall off, which will damage the original shape and destroy the indoor beautification environment. The wear resistance of gypsum board is ave...
