Abstract

The invention belongs to the technical field of building paint production, and particularly relates to building waterproof paint, and further discloses a preparation method of the building waterproofpaint. The building waterproof paint is prepared by using sticky rice powder and farm products as substrates, using quartz powder, calcite powder and diatom ooze as filling materials, and adding polyglutamic acid and polylactic acid fiber subjected to modification treatment. The bonding performance and the waterproof performance are further enhanced, so that the paint has the characteristics of good bonding performance, waterproof and dampproof effects, no peeling, no falling, non-toxicity, harmlessness and no pollution. Compared with the existing technical scheme, the paint has better waterproof performance.

Description

technical field [0001] The invention belongs to the technical field of architectural paint production, in particular relates to an architectural waterproof paint, and further discloses a preparation method thereof. Background technique [0002] With the improvement of people's living standards, the requirements for the living environment are also increasing, which has led to the rapid development of the construction and decoration industries. Traditional building interior wall coatings contain formaldehyde, which poses serious harm to people's health, and are gradually eliminated by the market. Non-toxic and environmentally friendly coatings have become people's first choice. After years of development, some interior wall paints have reached national standards and meet the requirements of non-toxic and harmless paints. However, these environmentally-friendly paints cannot be directly applied to the wall. Putty is used as the bottom layer. During the construction of the putt...
