Embodiment 1

[0026] Embodiment 1 is an anticorrosion paint specially used for oil storage tanks and facilities. It is composed of two components A and B packaged in separate tanks. When used, the two tanks of A and B can be opened on site and mixed in a ratio of 1:1. After stirring evenly, settle for 10 minutes, then spray, brush or roll. Its characteristic is that component A is a moisture-curing polyurethane resin composed of isocyanate, polyether a, polyether b, epoxy resin, dioctyl or dibutyl ester, phosphoric acid and solvents, and component B is composed of coal tar pitch, cyclic Coal tar pitch resin composed of hexanone, toluene, solvent and additives, wherein the isocyanate is polymethylene polyphenyl isocyanate (PAPI) 400 # , The solvent is xylene, the polyether a is 330, the polyether b is 635, and the additive is aluminum powder. During preparation, 29.2 parts of polymethylene polyphenylisocyanate (PAPI) 400 # Put it into the reaction kettle with a pump, add 0.047 parts of pho...

Abstract

The present invention relates to high molecular compound, and the anti-corrosive paint specially for petroleum storage tank and apparatus includes two separately canned components, component A and component B. The component A is wet cured polyurethane resin comprising isocyanate, polyether a, polyether b, epoxy resin, dioctyl ester or dibutyl ester, phosphoric acid and solvent. The component B is coal-tar pitch resin comprising coal-tar pitch, cyclohexanone, toluene, solvent and additive. The present invention has the beneficial effects of thin coating, low cost, easy coating, long service life, high anticorrosive effect, high mechanical and physical performace, excellent temperature tolerance, ultraviolet ray resistance and ageing resistance, etc.

Description
