Abstract

The invention discloses a mortar exterior wall coating and a preparation method, wherein the mortar exterior wall coating comprises components with weight proportion: water 18 parts, hydroxyethyl cellulose 0.9 part, calcium carbonate 6 parts, acrylic polymer latex paints 39 parts, ethylene glycol 1.1 parts, defoamers 0.6 part, ammonia water 0.4 part, preservatives 0.07 part, dispersants 0.7 part, 80 meshes silica sands 88 parts, titanium dioxide 6 parts, talcum powder 8 parts and heavy calcium carbonate 11 parts. The mortar exterior wall coating and the preparation method can be used to press and wipe building exterior walls of stadiums, cultural palaces, residences, grogshops, schools and hospitals and the like, has the advantages of excellent environmental protective performance, simple construction, simple process, no pollution, no toxicity and no flavor and the like, and has the characteristics of strong adhesive force, frost resistance, strong corrosion resistance, gloss retention, color retention, strong weatherability, mold prevention and algae resistance and the like.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an architectural coating, which can be used for mortar exterior wall coatings for stadiums, cultural palaces, residences, hotels, schools, hospitals and other building exterior walls. It has good environmental performance, simple construction, simple process, and no Pollution, non-toxic, tasteless and other advantages, and has the characteristics of adhesion, cold resistance, strong corrosion resistance, gloss retention, color retention, strong weather resistance, mildew resistance and algae resistance. Background technique [0002] Mortar: The bonding substance used for bricklaying in buildings. It is composed of a certain proportion of sand and cementing materials (cement, lime paste, clay, etc.) and water. It is also called mortar and mortar. Mortar is made by mixing cementitious materials (cement, lime, clay, etc.) and fine aggregate (sand) with water. Commonly used are cement mortar...
