Problems solved by technology

Large white powder is cheap, so it is widely used, but the smoothness of the painted wall is poor, the fastness is low, easy to fall off, poor moisture resistance, and difficult to remove dirt; the price of various paints is also low, but durable Poor performance and low finish; plastic wallpapers, wall coverings, etc. have strong texture, beautiful and luxurious, but the price is high, easy to damage and have electrostatic induction and natural aging; tiles have high finish, can increase the sense of coordination of the room, and are waterproof, moisture-proof and anti-fouling, but Only suitable for local environment and high price
Paint is a substance that can form a complete paint film on the surface of an object and can firmly adhere to the surface of the object. It is widely favored by consumers because of its light texture and bright color, but its adhesion and corrosion resistance have yet to be developed. improve

Abstract

The invention relates to slurry containing natural stone powder as well as a preparation method and an application of the slurry. The slurry comprises raw materials in parts by weight as follows: 40-50 parts of the natural stone powder, 20-30 parts of a tackifying emulsion, 4-6 parts of silica sol, 35-45 parts of modified acrylic resin and 5-10 parts of triisopropanolamine. When the slurry prepared from the natural stone powder and other components through scientific proportioning is applied to a wall surface, the wall surface can have the excellent properties of heat resistance, sound insulation, friction resistance, corrosion resistance, waterproofing, dampproofing, non-combustion, environmental protection and the like, and the slurry can be applied to decoration of various wall surfaces.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a slurry containing natural stone powder and its preparation method and application. Background technique [0002] The main purpose of building interior wall decoration is to protect the wall, beautify the wall environment, and make the decorated wall look brand new, fresh and environmentally friendly. At present, whitewashing, paint coatings, plastic wallpapers and ceramic tiles occupy the market for architectural interior decoration fabrics. Large white powder is cheap, so it is widely used, but the smoothness of the painted wall is poor, the fastness is low, easy to fall off, poor moisture resistance, and difficult to remove dirt; the price of various paints is also low, but durable Poor performance and low finish; plastic wallpapers, wall coverings, etc. have strong texture, beautiful and luxurious, but the price is high, easy to damage and have electrostatic indu...
