Novel environment-friendly thermal insulation anti-corrosive coating

Abstract

The invention discloses novel environment-friendly thermal insulation anti-corrosive coating. The novel environment-friendly thermal insulation anti-corrosive coating comprises a component A, a component B and a component C, wherein the weight ratio of the component A to the component B to the component C is (500-1000): (50-80): 2, the component A comprises the following materials in parts by weight: 40-50 parts of acrylic emulsion, 140-180 parts of titanium dioxide, 35-45 parts of lithopone, 5-8 parts of expanded perlite, 3-5 parts of hollow glass beads, 3-5 parts of vermiculite, 3-5 parts of sericite powder, 8-12 parts of epoxy resin, 12-18 parts of acetone, 3-8 parts of ethylene glycol monobutyl ether, 1-3 parts of commercially available OP-10 type emulsifier, 0.1-0.3 part of sodium hydroxide, 30-50 parts of ethanol and 70-100 parts of deionized water; the component B comprises the following materials in parts by weight: 3-5 parts of coating curing agent, 2-4 parts of tetrachloroisophthalonitrile, 1-2 parts of antifreeze agent, 0.3-0.8 part of defoaming agent, 0.1-0.15 parts of sterilizing agent, 0.1-0.4 part of dispersant, 1-1.5 parts of alkali swelling thickening agent, 0.1-0.2 part of cellulose thickener, 0.1-0.15 part of wetting agent and 0.5-1 part of film-forming agent; and the component C is ultramarine or phthalocyanine blue or phthalocyanine green or phthalocyanine red or bright red.

Description

technical field [0001] The invention relates to a novel anti-corrosion coating and a preparation method thereof, more specifically, to a novel environmental-friendly heat-insulating anti-corrosion coating. 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 continuous rainfall process. Therefore, it has great lim...
