Abstract

The invention relates to the technical field of fine chemical coating, in particular to fine chemical coating and a process for producing the same. The fine chemical coating comprises, by weight, 10-18 parts of chitosan, 15-22 parts of montmorillonite, 6-14 parts of polyaniline, 3-9 parts of waterborne fluorocarbon resin, 2-11 parts of epoxy resin, 4-9 parts of fluorosilicon resin, 1-4 parts of isobutanol, 5-12 parts of butyl acetate, 2-6 parts of expanded graphite, 3-8 parts of titanium dioxide, 0.5-2.5 parts of defoaming agents and an appropriate quantity of water. The fine chemical coatingand the process have the advantages that the fine chemical coating prepared by the aid of the process is good in barrier property, and the ageing resistance of the fine chemical coating can be enhanced; metal can be effectively stopped from being eroded by environmental corrosion media such as water molecules and oxygen, and accordingly excellent anticorrosion effects can be realized by the fine chemical coating; the weather resistance and the antifouling properties of coatings can be obviously improved by the fine chemical coating.

Description

technical field [0001] The invention relates to the technical field of fine chemical coatings, in particular to a fine chemical coating and a production process thereof. Background technique [0002] Fine chemical industry is a general term for the production of fine chemical industry, referred to as "fine chemical industry". The meaning of fine chemicals is still under discussion abroad. All chemical products with the following characteristics are generally called fine chemicals, namely: many varieties, fast replacement; small output, mostly produced in batches; functional or end-use; many are compound products, formulas and other technical decisions Product performance. [0003] Paint is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, or oil, or emulsion, with or without adding pigments, fillers, adding The corresponding additives are viscous liquids prep...
