Abstract

The invention discloses an exterior wall coating. The exterior wall coating is prepared from, by weight, 5-10 parts of attapulgite powder, 22-28 parts of white latex, 5-10 parts of titanium dioxide, 6-12 parts of hydroxyethylcellouse, 3.5-7.2 parts of trans-2-hexenal, 4.5-8.5 parts of (S)-4-isopropenyl-1-cyclohexenylmethanol, 1.2-3.5 parts of a polyurethane modified nitrocellulose film forming agent and 2.5-3.7 parts of sodium hydrosulfite. Compared with present latex paints, the exterior wall coating has the advantages of good weatherability, good ultraviolet resistance, fast drying time, realization of flat, smooth and fine films due to addition of hydroxyethylcellouse and trans-2-hexenal, strong pollution resistance and excellent adhesion due to addition of the polyurethane modified nitrocellulose film forming agent, effective prevention of mildews and algae, good levelability, and safe and convenient construction, and is an ideal exterior wall decoration material.

Description

technical field [0001] The invention relates to an exterior wall coating, which belongs to the field of architectural coatings. Background technique [0002] At present, there are many types of paints used for exterior walls, and latex paint is one of the most widely used wall decoration materials, and latex paint is the safest material among many paints. Exterior wall latex paint not only needs good weather resistance and ultraviolet resistance, but also the coating film should be smooth and fine texture, but the existing exterior wall latex paint is difficult to meet the required requirements at the same time. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide an exterior wall coating with comprehensive performance, high weather resistance and ultraviolet resistance, and strong adhesion. [0004] In order to solve the above-mentioned technical problems, the technical s...
