Decorative plate for permanently curing damping and dewing of internal walls and preparation method for decorative plate

Abstract

The invention discloses a decorative plate for permanently curing damping and dewing of internal walls and a preparation method for the decorative plate. Raw materials of the decorative plate comprise a component A and a component B, wherein the component A contains cement, bentonite, diatomite, gypsum powder, hydroxypropyl methylcellulose, calcium lignosulfonate and polypropylene anti-crack fibers; and the component B contains a certain amount of a mixture of all the ingredients of the component A, water and EPS granules. The preparation method comprises the steps of mixing the component A and the component B, and then, carrying out uniform stirring, so as to obtain a size mixture; and then, laying gridding cloth on a backing plate, then, tiling the size mixture on the gridding cloth, then, re-laying a layer of gridding cloth on the surface of the size mixture, then, carrying out cutting according to specifications, and then, carrying out natural air-drying, thereby obtaining the decorative plate. The decorative plate provided by the invention plays roles in preserving heat, proofing dampness, dehumidifying and regulating and controlling the temperature and humidity of indoor wall bodies; and meanwhile, the decorative plate has the remarkable functions of retarding inflaming, not deforming, not cracking, being sturdy and durable, generating self-breathing, and the like, is free of any odor and is harmless to human health.

Description

technical field [0001] The invention belongs to the field of building material preparation, and in particular relates to a decorative board for radically curing moisture and condensation on inner walls and a preparation method thereof. Background technique [0002] The disease damage in the construction field, especially the problem of building moisture damage, is one of the major problems that have always plagued the industry. Among them, humidity is also damaged by moisture, such as moisture return and condensation, which are common and difficult to eliminate common building diseases in buildings. Since the above occurs slowly during building construction and building use, it is difficult to detect and difficult to cure. The damage of building moisture to buildings is very extensive, such as: 1) Freezing and thawing: The severe building damage caused by humidity is mainly caused by freezing and thawing. Most building materials have a certain porosity and absorb water. In...

AI Technical Summary

Problems solved by technology

Many walls use cement, mortar, marble, and wall materials such as limestone, etc., which cannot withstand corrosion. Groundwater will damage the wall materials through penetration, and at the same time destroy steel bars and other materials, causing serious damage.

5) Mold: In southern and southwestern my country, due to moderate summer, the air temperature and moderate temperature are easy to breed mold, and the wall is easy to breed mold due to moisture, and mold spots or patches of black often appear on the surface of the wall, which seriously affects the decoration of the wall. effect, but also affect the furniture and home environment, thereby affecting the health of occupants

[0003] At present, there is no effective means to solve the problem of building moisture damage, especially for the molded buildings that have been used for many years, the problem of moisture damage is even more troublesome for users
