Problems solved by technology

[0002] At present, the decoration of building walls generally adopts traditional coatings. Most of the coatings are limited to the characteristics of high elasticity, their wear resistance and water resistance are poor, their tensile strength is low, and their adhesion is average. They are generally only used for interior decoration. , now people pay more and more attention to the living environment, so the exterior decoration of buildings has attracted more and more attention. Because it is not wear-resistant and waterproof, the pain...

Abstract

The invention discloses an abrasion-resistant waterproof coating for a building outer wall. The abrasion-resistant waterproof coating comprises, by weight parts, 60-80 parts of modified EPDM resin, 30-60 parts of epoxy acrylic resin, 20-40 parts of styrene-acrylic emulsion, 10-30 parts of polyurethane, 5-15 parts of polyisocyanate, 2-8 parts of ethylene glycol monoethyl ether acetate, 3-8 parts of graphite powder, 2-6 parts of feldspar powder, 1-5 parts of magnesium silicate, 2-6 parts of phenol, 3-5 parts of carboxymethyl cellulose, 2-5 parts of hydroxypropyl methylcellulose, 3-7 parts of dipropylene glycol methyl ether, 2-8 parts of phenol, 3-7 parts of xylene, 2-6 parts of potassium chromate, 1-3 parts of aluminum hydroxide, 2-4 parts of barium sulfate, 1-3 parts of flatting agent, 2-6 parts of defoamer and 1-5 parts of silane coupling agent. The invention further discloses a method for preparing the abrasion-resistant waterproof coating for the building outer wall. The abrasion-resistant waterproof coating for the building outer wall is excellent in abrasion resistance, good in waterproof performance, long in service life and low in cost.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a wear-resistant and waterproof coating for building exterior walls and a preparation method thereof. Background technique [0002] At present, the decoration of building walls generally adopts traditional coatings. Most of the coatings are limited to high elasticity, poor wear resistance and water resistance, low tensile strength, and general adhesion. Generally, they are only used for interior decoration. , now people pay more and more attention to the living environment, so the exterior decoration of buildings has attracted more and more attention. Because it is not wear-resistant and waterproof, the paint film will peel off as a whole after being washed by rain, which looks very unsightly. The requirements for the paint coating applied on the outer layer of the building are getting higher and higher. The waterproof and anti-seepage problem of the building is related to people's workin...
