Abstract

The invention discloses an anti-ultraviolet and high-temperature-resistant coating for building exterior walls, which comprises the following components in parts by weight: 35-55 parts of polyaspartic acid ester resin, 15-20 parts of nano-scale ceramic powder, and 10-16 parts of methyl acrylate, 5-12 parts of lignosulfonates, 6-13 parts of crystalline type II ammonium polyphosphate, 10-16 parts of sepiolite, etc. The coating prepared by the invention has good fluidity, excellent ultraviolet resistance and high temperature resistance, fast coating drying and solidification speed, flexible color matching, convenient and fast construction, and simple manufacturing method.

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...
