Environment-friendly external wall paint containing shell powder

Abstract

The invention relates to an environment-friendly external wall paint containing shell powder, which is prepared from the following raw materials in parts by weight: 60-80 parts of shell powder, 40-60 parts of pure acrylic emulsion, 30-50 parts of styrene-acrylic emulsion, 5-10 parts of surfactant, 5-10 parts of hydroxypropyl methyl cellulose, 5-10 parts of aluminum hydroxide, 10-20 parts of calcium oxide, 3-5 parts of magnesium silicate, 5-10 parts of zeolite powder, 5-10 parts of polyvinyl alcohol, 1-5 parts of nanometer calcium carbonate, 1-2 parts of titanium pigment, 1-3 parts of polyethylene glycol, 1-3 parts of turpentine, 1-3 parts of chitosan, 1-3 parts of triethylenetetramine, 0.1-1 part of sodium fluoride, 0.1-0.5 part of water silicon oil, 1-3 parts of defoamer, 1-3 parts of dispersant, 3-5 parts of propylene glycol and 30-50 parts of de-ionized water. The environment-friendly external wall paint provided by the invention contains multiple kinds of specific components which play a mutual synergy effect, so that the prepared paint has the advantages of good wear resistance, strong adhesive force, ageing resistance, acid and alkali resistance as well as a function of removing formaldehyde, and the paint is green and environment-friendly, non-toxic and harmless to human body and wide in market prospects.

Description

technical field [0001] The invention relates to the field of daily chemical coating, and relates to an exterior wall paint, in particular to an environment-friendly exterior wall paint containing shell powder. Background technique [0002] At present, traditional building materials such as granite, mosaic, face brick, aluminum alloy glass are still used in most of the exterior wall decorations of buildings in our country. According to reports, the exterior walls of buildings in major cities in Western Europe are almost decorated with paint. Japan and other countries use coatings to decorate the building exterior walls as high as 70% to 90%. The building laws of countries such as Singapore and Malaysia stipulate that high-rise buildings are not allowed to use materials such as facing bricks for decoration. In the future, my country's building exterior wall decoration is bound to take the road of replacing facing bricks and mosaic materials with paint. At present, the follow...
