Abstract

The invention discloses a durable exterior wall coating material, which is prepared from the following raw materials in parts by weight: 3 to 7 parts of 4-vinyltoluene, 10 to 15 parts of titanium pigments, 25 to 33 parts of white emulsions, 2.5 to 4.6 parts of sodium hexametaphosphate, 7.3 to 8.1 parts of deionized water, 1.5 to 3.8 parts of 2,5,6-trimethyl-4-heptenal, 2.6 to 6.3 parts of dibenzylphenol polyoxyethylene ether, 2.5 to 6.5 parts of nitric acid fiber film forming agents, 1.3 to 3.2 parts of cis-1,2-dihydroxymethyl ethylene, and 2.8 to 6.2 parts of 1,2-dimethyl phthalate. Compared with an existing product, the durable exterior wall coating material is good in low temperature stability, high in water resistance and alkali resistance, has anti-scrubbing times of 2000 to 2500 times, is long in service life, is not abnormal when a coating is subjected to a temperature fluctuation resistance test for over 5 times, and is short in drying time; a paint film is level, attractive and elegant in appearance.

Description

technical field [0001] The invention relates to a durable exterior wall coating and a preparation method thereof, belonging to the field of architectural coatings. Background technique [0002] Engineering latex paint is latex paint used in engineering, and its ingredients are usually composed of petrochemical raw materials such as vinyl acetate, acrylate, styrene emulsion, titanium dioxide, talcum powder and some additives. The engineering latex paint of the prior art has the disadvantage of poor weather resistance, so it is necessary to develop a high-quality engineering latex paint that can improve its weather resistance. 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 a durable exterior wall paint and a preparation method thereof, which not only meet the properties of latex paint, but also have excellent weather resistance. [0004] In order to solve the above tec...
