Abstract

The invention relates to a weather resistant epoxy-polyurethane anti-corrosion coating and a manufacturing method thereof, which adds phenol-A epoxy resin, bisphenol-F epoxy resin, hydroxyl contained saturated polyester resin and fluorocarbon resin into the mixed solvent of dimethylbenzene, n-butyl acetate, methyl isobutyl ketone and butanone; then adds rutile type titanium pigment, saponite, sericite in powder, polyacrylate co-polymer, polymethyl alkyl siloxane, benzotriazole, gas phase silica and iso-caprylic acid znic to make the fluid A of the weather resistant epoxy-polyurethane anti-corrosion coating while adds fatty group polyisocyanate into the mixed liquor of anhydro-dimethylbenzene and the n-butyl acetate to make fluid B, and mix the two components during application. The invention can be applied to the preservation of the surfaces of outdoor steel structures, pipes and concrete requiring weather resistance, light aging resistance and acid, alkali and salt corrosion resistance.

Description

technical field [0001] The invention relates to a weather-resistant epoxy polyurethane anti-corrosion coating and a manufacturing method thereof, which are used for anti-corrosion of steel structures, pipelines and concrete surfaces that require weather resistance, light aging resistance and acid, alkali and salt corrosion resistance outdoors. Background technique [0002] The existing epoxy polyurethane anti-corrosion coatings are generally used for internal anti-corrosion of storage tanks, pipelines, etc., and have good acid, alkali, and salt corrosion resistance. The disadvantages are that the paint film is prone to yellowing, poor weather resistance, and poor light aging resistance. , cannot be used for corrosion protection of outdoor steel. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an epoxy polyurethane anti-corrosion coating with good weather resistance, good light aging resistance and corrosion resis...
