Abstract

The invention relates to an ultraviolet ray resistant coating for high temperature interface construction and the preparation method thereof. One portion of hexa-methylene diisocyanate trimer-modified polyisocyanate, 0.1-0.4 portions of xylene and 0.1-0.3 portions of ammonia ester level butyl acetate are mixed together to obtain A solution; 0.01-0.05 portions of unsaturated polybasic carboxylic acid polymer solution, 0.1-0.4 portions of a mixer which are made of xylene, bivalency mixed acid dimethyl ester, isophorone according to the proportion of 65:25:10, 0.05-0.2 portions of nanometer level zirconia, one portion of hydroxy acrylic acid, 0.1-0.2 portions of organosilicon-modified acrylic resin, 0.2-0.4 portions of saturated polyester, 0.2-0.6 portions of rutile type white titanium pigment which has been enveloped by aluminum and has been worked organically, 0.01-0.1 portions of silicon dioxide powder, 0.01-0.5 portions of calcined kaolin, and 0.002-0.01 portions of acrylic ester copolymer solution are mixed together to obtain B solution; one portion of A solution and 8-12 portions of B solution are mixed together for being used as anticorrosive paint on external surfaces of pipelines, storage tanks and steel constructions in high temperature areas.

Description

technical field [0001] The invention relates to an anti-ultraviolet coating and a preparation method for anti-corrosion high-temperature interface construction on the outer surfaces of pipelines, storage tanks, steel structures and the like in areas with strong sunlight. Background technique [0002] When the existing external anti-corrosion coating is applied on the high-temperature steel interface, defects such as blistering and shrinkage will occur, resulting in a decrease in the anti-corrosion performance of the coating and a shortened service life; , the coating film is prone to discoloration, loss of gloss, and pulverization, which seriously affects normal production and increases the cost of maintenance and management. Contents of the invention [0003] The purpose of the present invention is to avoid the above-mentioned deficiencies in the prior art, and to provide an anti-ultraviolet coating and a preparation method that can be applied on high-temperature interfac...
