Preparation process of epoxy resin paint

Abstract

The invention belongs to the technical field of coating preparation processes, and particularly relates to a preparation process of an epoxy resin coating. The process comprises the following steps of(S1) selecting raw materials: taking water, polyvinyl alcohol, bisphenol A-epoxy resin and sodium cellulose, preparing a colloidal solvent A by adopting a conventional glue boiling process, putting whiting powder, light calcium carbonate, ash calcium powder, talcum powder and expansive soil into a charging barrel, and mixing and stirring to prepare a powder mixture B, (S2) grinding and crushing:putting the powder mixture B prepared in step (S1) into a grinding machine to be fully ground and crushed, (S3), filtering the raw materials: filtering the ground and crushed powder mixture B in stepS2 through a filtering device to filter out impurities and a large-particle mixture in the mixture; and (S4) packaging the raw materials: preventing the phenomenon that the coating is adhered in the discharging barrel since the coating has an adhesive when the colloid solvent A and the powder mixture B are mixed and prepared and then put into the discharging barrel.

Description

technical field [0001] The invention belongs to the technical field of paint preparation technology, in particular to a preparation technology of epoxy resin paint. Background technique [0002] Epoxy resin, as a kind of high-performance resin, is widely used. It has many advantages, including strong adhesion with various bases, high hardness of the coating, good water and chemical resistance, good wear resistance, etc. It can be used as floor coatings, metal coatings, etc. Anti-rust primer, marine coating, etc. But at present, most epoxy resins are solvent-based products. In recent years, various environmental protection regulations have been promulgated one after another, making the research and application of water-based epoxy resins an inevitable trend. [0003] Epoxy resin coatings have good mechanical properties, electrical insulation properties, good thermal and chemical stability, and have the advantages of anti-corrosion, waterproof, mildew-proof, and low shrinkag...

AI Technical Summary

Problems solved by technology

[0005] In order to make up for the deficiencies in the prior art, the present invention proposes a preparation process for epoxy resin coatings. The present invention is mainly used to solve the problem that the raw materials of the coatings contain certain adhesives during the preparation of existing epoxy resin coatings. , and then when the epoxy resin coating is stored and packaged in the metal discharge barrel, the adhesive in the paint will make the paint stick to the inner wall of the barrel, which not only reduces the efficient and full utilization of the epoxy resin coating, but also Affect the effect of cleaning and reusing the discharge barrel
