Abstract

The invention discloses a wallboard containing a PVC modified material and a preparation method thereof. The wallboard comprises, by weight parts, 100-120 parts of purified water, 5-10 parts of maleicanhydride, 15-30 parts of emulsifier, 15-30 parts of ethanol, 20-40 parts of environmentally friendly plasticizer, 4-10 parts of polyvinyl chloride resin, 20-60 parts of vinyl chloride polymer, and 15-40 parts of sponge cells. The preparation method includes the following steps: step S1 of preparation of a PVC modified component: adding, by weight parts, 100-120 parts of purified water, 15-30 parts of emulsifier and 15-30 parts of ethanol to a reactor, stirring evenly, and forming a blend A. The purpose of the wallboard is to provide the wallboard containing the PVC modified material and thepreparation method thereof to solve the problems of poor gas permeability, poor strength, no toughness, no environmental protection caused by the addition of formaldehyde and other auxiliaries.

Description

technical field [0001] The invention relates to the technical field of PVC modified materials, in particular to a wallboard containing PVC modified materials and a preparation method thereof. Background technique [0002] PVC material wall panels can be completely customized according to product design requirements. The output is rich in color, texture, and color, and the price is relatively low, which is generally welcomed by consumers. PVC is a vinyl polymer, and its material is a non-crystalline material. In actual use, PVC materials are often added with stabilizers, lubricants, auxiliary processing agents, colorants, anti-impact agents and other additives. Flammability, high strength, weather resistance and excellent geometric stability. However, PVC material wallpaper also has disadvantages. Most PVC wallpapers have poor air permeability. It can be corroded by concentrated oxidizing acids such as concentrated sulfuric acid and concentrated nitric acid, and it is not s...
