Coating preparation process

Abstract

The invention discloses a coating preparation process. The coating preparation process is characterized by comprising the first step of raw material selection, wherein raw materials comprise, by weight, 55% of polystyrene foam, phenolic foam plastic, scrap rubber and nitrocellulose, 20% of industrial alcohol, coal tar, acetone and hydrosolvents, 20% of pigments and fillers and 5% of wetting dispersing agents, defoaming agents, flatting agents and plasticizer auxiliaries; the second step of fusing refining; the third step of pre-refining; the fourth step of dispersing; the fifth step of blending and color mixing; the sixth step of filtering; the seventh step of packaging. The coating preparation process is reasonable and simple, the process flow is greatly shortened, the raw materials of the coating are wide in source and are of a waste recycling type, and production cost is reduced; meanwhile, according to the raw material ratio, coating of different functions is convenient to make and meets the needs of other production processes, material capacity and the ratio are accurate, the deviation is small, product quality is guaranteed, and the enterprise yield is effectively increased.

Description

technical field [0001] The invention relates to the field of chemical technology, in particular to a coating preparation technology. Background technique [0002] At present, coatings have been widely used in the construction industry, packaging materials, household daily necessities and automobiles and other fields. Paint is a chemical mixture that can firmly cover the surface of objects for protection, decoration, marking and other special purposes. With the continuous expansion of industrialized large-scale production and the continuous improvement of people's living standards, some domestic garbage and industrial waste continue to increase, which has brought serious environmental pollution to the society. Waste and old foam plastics, waste rubber and coal tar have caused serious environmental pollution. Serious "white pollution" and "black pollution" have become a worldwide public hazard, endangering people's quality of life and restricting the development of the nation...

AI Technical Summary

Problems solved by technology

Although most coating preparation processes are simple now, the process has great ambiguity, so the product coatings produced are highly polluting and the cost of raw materials is also high. For example, the application number CN200610020827.5 discloses a coating preparation process , put anhydrous coal tar and anhydrous phenol oil into the heating kettle, after stirring, add polyvinyl chloride powder, dioctyl phthalate, barium stearate, after stirring, heat, add talcum powder, keep warm, Stop heating, cool down, stop stirring, the advantages of the present invention: it has weather resistance, elasticity, elongation, cohesiveness, the coating film is not brittle or cracked at low temperature, and does not flow at high temperature, but there is no well-organized process Process, clear raw material ratio, in this kind of process, only one kind of coating can be produced, which is not suitable for the development of enterprises and the improvement of enterprise benefits
