Environment-friendly thermal-insulation external wall paint prepared from wastes and preparation method thereof

Abstract

The invention discloses an environment-friendly thermal-insulation external wall paint prepared from wastes. The invention is characterized in that the paint is prepared from the following raw materials in parts by weight: 8-11 parts of polyacrylate emulsion, 3.5-4.5 parts of polyacrylamide, 1-2 parts of sulfonated oil, 2-3 parts of hydroxyethyl cellulose, 10-13 parts of expanded vermiculite powder, 3-5 parts of microporous calcium silicate, 3-5 parts of hollow microbead, 4-5 parts of rice hull, 5-7 parts of field weed, 2.5-4 parts of bean protein adhesive, 6-8 parts of modified round-grain mortar and 25-30 parts of water. The rice hull, field weed and other wastes are changed into valuable substances by special treatment, thereby increasing the toughness of the paint film. By matching the microporous calcium silicate and other components, the paint has favorable thermal-insulation effect. The added modified round-grain mortar has the advantages of light weight and favorable dispersity, increases the brightness, viscosity and strength of the paint, can not easily shed, and can not increase the pressure of the buildings. The produced paint is simple for construction, and has the advantages of high covering power, wide application range, elegant appearance and high practicality.

Description

Technical field [0001] The invention relates to a paint and a preparation method thereof, in particular to an environmentally friendly thermal insulation exterior wall paint using waste and a preparation method thereof. Background technique [0002] Round-grained quartz sand is finely processed from natural quartz sand through multiple processes. The product contains high silicon content, is pelletized, has good air permeability, good fluidity, and high compressive strength, which is suitable for many purposes. For coatings, the appropriate particle size ratio, small accumulation voids, saving the amount of resin, and good compatibility with various resins, acid resistance, alkali resistance, chemical solvent resistance, and hot water resistance. However, the density of round-grained sand is high. It is added to the paint and sprayed on the outer wall, increasing the weight of the building, wind and sun, there is also the risk of falling off the wall, and it has an impact on the...

Problems solved by technology

However, the density of round sand is high, adding it to the paint and spraying it on the outer wall will increase the weight of the building, and there is a danger of falling off the wall due to wind and sun, and it will also affect the dispersion of the paint.
