Environment-friendly ultraviolet light resistant and high-temperature resistant paint for outer walls of buildings

Abstract

Environment-friendly ultraviolet light resistant and high-temperature resistant paint for outer walls of buildings comprises A compositions, B compositions and a C composition, wherein the A compositions comprise the following substances in parts by weight: 25-35 parts of polyaspartic acid ester resin, 20 parts of an aromatics mixed solvent, 8-10 parts of nano-scale ceramic powder, 2-4 parts of mica powder, 10-18 parts of diacetone alcohol, 3-8 parts of ethylene glycol monobutyl ether, 7-11 parts of a cellulose thickener solution with the mass percent of 2%, 1.0-1.4 parts of a polyphosphate dispersing agent solution with the mass percent of 10%, 1-3 parts of an emulgator, 0.1-0.3 part of sodium hydroxide, 30-50 parts of ethyl alcohol, 70-100 parts of deionized water, 140-180 parts of titanium dioxide; the B compositions comprise the following substances in parts by weight: 3-5 parts of a paint curing agent, 0.02-1 part of an initiator, 1 part of a dispersing agent, 0.6 part of a flatting agent, 0.3 part of an antifoaming agent, 0.3 part of a defoaming agent, 25 parts of a modified ammonia curing agent, 2-4 parts of tetrachloroisophthalonitrile, 3-5 parts of a dry film antiseptic; the C composition is an environment-friendly color mixed-phase inorganic pigment.

Description

technical field [0001] The invention relates to a novel anti-corrosion coating and a preparation method thereof, more specifically, to an anti-ultraviolet and high-temperature-resistant coating for the exterior wall of an environment-friendly building. Background technique [0002] In the prior art, most commonly used building exterior wall coatings are coatings prepared with styrene-acrylic emulsions, pure acrylic emulsions or elastic acrylic emulsions as base materials. Its disadvantages are small cracks after being applied to the wall, poor strength, poor stain resistance and low temperature performance; in addition, due to the presence of styrene in the coating, the smell is quite strong; when the exterior wall is coated, a large amount of smell is emitted in the atmosphere. In addition, the curing time of this type of coating is relatively long. Therefore, it is necessary to pay attention to weather changes when coating, and it cannot be constructed during the continuou...
