Anticorrosion paint for metals

Abstract

An anticorrosion paint for metals is made from, by weight, 12 to 15 parts of vinyl chloride-vinyl acetate resin, 2 to 4 parts of ammonium polyphosphate, 6 to 9 parts of dimethylbenzene, 3 to 5 parts of cobalt-manganese rare earth, 15 to 20 parts of calcium molybdate, 8 to 14 parts of Duanbaifen, 30 to 42 parts of modified aluminum powder, 2 to 4 parts of urotropin, 5 to 10 parts of cellulose hydroxyethyl ether, 3 to 6 parts of n-butyl alcohol, 1 to 2.5 parts of waste food oil, 7 to 15 parts of hydrated alumina, 0.2 to 0.5 part of flame-retardant fiber, 5 to 10 parts of polybutylene, 10 to 22 parts of hydroxyethyl cellulose, 12 to 16 parts of aluminum sulfate solution, 4 to 7 parts of Callistemon rigidus saw dust, and 3 to 5 parts of dodecyl acrylate. The anticorrosion paint is excellent in corrosion resistance and durability, allows a coating to be tough and highly adhesive, and is free of pollution, nontoxic and safe.

Description

technical field [0001] The invention relates to an anticorrosion paint for metal. Background technique [0002] Corrosion of metal is a phenomenon in which metal is destroyed by chemical or electrochemical action of environmental medium. The corrosion of metals spreads all over the national economy and brings huge losses to the national economy. In industrially developed countries, the direct economic loss caused by corrosion accounts for 1% to 4% of the total output value of the national economy, the annual corroded and rusted steel accounts for about 20% of the output, and about 30% of the equipment is scrapped due to corrosion. In China, the economic loss caused by metal corrosion is as high as more than 30 billion yuan per year, accounting for 4% of the gross national product. Nowadays, with the advancement of industrial technology, the use of metal materials is becoming more and more extensive. The corrosion of metal and its components not only causes huge waste of ma...
