Durable building exterior wall paint

Abstract

The invention discloses durable building exterior wall paint. The durable building exterior wall paint is prepared from the following raw materials in parts by weight: 10 to 15 parts of titanium dioxide, 20 to 25 parts of white emulsion, 2.5 to 4.7 parts of 3-methoxyl-4-tyrosol, 2.7 to 4.2 parts of petroselinic acid methyl ester, 5 to 8 parts of n-butyl acetate, 1.2 to 2.7 parts of vanillin, 3.4 to 6.2 parts of isooctyl phenol polyethoxylate and 2.7 to 6.5 parts of ethylene-vinyl acetate copolymers. Compared with existing exterior wall emulsion paint, the petroselinic acid methyl ester is added to be mixed with the white emulsion, so that the covering power of a finished product of the emulsion paint is increased; the n-butyl acetate and the titanium dioxide are mixed, so that the adhesive force and water and scrubbing resistance of the finished product of the emulsion are increased; the purple isooctyl phenol polyethoxylate and the ethylene-vinyl acetate copolymers are mixed, so that a paint film is bright for a long time and resists pollution for a long time.

Description

technical field [0001] The invention relates to a durable building exterior wall paint, which belongs to the field of building coatings. Background technique [0002] There are many kinds of exterior wall paints, but each has its own characteristics. Some exterior wall paints have weak stain resistance, poor water and alkali resistance; some exterior wall paints lack elasticity and poor crack resistance; Mold and algae grow, seriously affecting the appearance and service life of the wall. Some exterior wall paints use volatile substances, which are harmful to human health and not safe enough. The latex paint for the environmental protection exterior wall preferably solves the above problems. Contents of the invention [0003] In view of the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a durable building exterior wall paint with strong hiding power, high adhesion, water scrubbing resistance, bright and durable pa...
