Special heavy anti-corrosion fluororesin coating material

Abstract

The invention discloses a special heavy anti-corrosion fluororesin coating material, which comprises the following raw materials in parts by weight: 20 parts of fluororesin, 18 parts of amino resin, 15 parts of vinyl copolymer, 10 parts of isocyanate, 5 parts of titanium dioxide and 23 parts of organic solvent. The special heavy anti-corrosion fluororesin coating material provided by the invention can be applied to protection of various metal substrates such as carbon steel, aluminum alloy and the like, and is suitable for corrosion prevention and wear resistance of equipment and components under various severe working conditions; the fluororesin has the advantages of high hardness, high gloss, super-strong weather resistance and salt mist resistance, and the surface is not easy to pollute and easy to clean on an extremely low surface; and the coating layer is free of pinholes and smooth in surface, is widely applied to drainage washing of chemical engineering and petroleum, sewage treatment systems, chemical cleaning systems of devices, chemical medicine distribution systems, automobiles, aerospace and the like, has very high practicability, and is suitable for popularization and application.

Description

technical field [0001] The invention relates to the field of anti-corrosion coatings, in particular to a special heavy-duty anti-corrosion fluororesin coating. Background technique [0002] Special heavy-duty anti-corrosion fluororesin coating refers to a type of anti-corrosion coating that can be applied in a relatively harsh corrosive environment and has a longer protection period than conventional anti-corrosion coatings. Currently, epoxy resin is mostly used in the field of anti-corrosion coatings. Anti-corrosion coatings, polyurethane coatings and chlorine-containing resin coatings are mainly used. Epoxy is prone to yellowing and chalking in outdoor applications. Although polyurethane coatings and chlorine-containing resin coatings are used outdoors, considering the actual ambient temperature , Humidity, the use of polyurethane coatings and chlorine-containing resin coatings are subject to certain restrictions. The special chemical structure in fluororesin makes fluoro...
