Substrate material capable of adjusting moisture and manufacturing method of substrate material

Abstract

The invention discloses a substrate material capable of adjusting moisture and a manufacturing method thereof, and discloses a substrate material for painting indoor walls of buildings. The substrate material contains sintered and non-sintered diatomite ingredients and auxiliary materials, such as gypsum, limestone, wood fiber, carclazyte, anti-mildew algicide, hydroxypropyl methylcellulose and powdered resin, and the like. The method is simple and easy to implement. Since having reasonable material proportion, the substrate material has strong crack resistance, adhesion, abrasion resistance, moisture absorption and moisture releasability; the root cause is as follows: the diatomite is used as the main raw material; since the diatomite is porous and has big specific surface area, the diatomite can store moisture and has excellent moisture retention; the moisture can be released in dry condition. Since having wood fiber and powdered resin, and the like, the crack resistance and abrasion resistance are strengthened; the fastness of the substrate material to a wall surface is improved. Moist and mildew can be effectively avoided by adding the anti-mildew algicide, and thus indoor environment is more environment friendly. The substrate material capable of adjusting moisture is ideal, and solves the problems of the existing substrate material.

Description

technical field [0001] The invention discloses a base material for painting indoor walls of a building, specifically a base material containing fired or unfired diatomite and a manufacturing method thereof. Background technique [0002] At present, in building interior wall decoration or painting operations, it is necessary to paint the base material first, and then paint or coat surface materials on the base material basis, such as scraping white, latex paint, etc. However, most of the existing base materials are gypsum-based materials, that is, gypsum is the main component and other auxiliary materials are added. This material has many disadvantages, such as unsatisfactory construction, mainly due to the high content of gypsum, which is easy to solidify, and the surface smoothness after construction is not good. The grip to the wall is also not ideal, and it is easy to fall off in the future. In addition, there are defects in crack resistance, moisture absorption and hum...
