Crystallized coating

Abstract

The invention belongs to the technical field of coatings and in particular relates to an environment-friendly high-performance crystallized coating. The crystallized coating comprises the following components in percentage by mass: 40-70 percent of a short oil alkyd resin, 5-20 percent of closed polyisocyanate, 5-20 percent of boiled tung oil, 5-20 percent of a solvent, 0-10 percent of a phenylated amino resin, 0-2 percent of a leveling agent, 0-5 percent of a slip additive, 0-3 percent of a closed acid catalyst and 0-2 percent of an adhesion promoter. Compared with the prior art, the crystallized coating disclosed by the invention has the advantages that the formula stability is high, and the storage period is long; the coating does not yellow when baked at a high temperature; the coating is environment-friendly and does not contain cobalt, manganese or other limited driers, the odor is small in the construction process, environment friendliness is realized, and the environment-friendly requirement is met; and moreover, coating in a roller painting mode can be realized, the loss is low, and the production efficiency can be greatly improved.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to an environment-friendly, high-performance crystal coating. Background technique [0002] Art paint, also known as art paint, is a paint variety with special performance composed of special materials and belongs to industrial paint. Like other paints, applying this kind of paint on the surface of the object will protect the object. The difference is that after the paint is formed into a film, various beautiful patterns or patterns will be formed or appear on the film. The appearance is colorful and layered. Clear, beautiful and generous, with obvious high decoration. [0003] Crystal texture paint is a kind of art paint, which is named for the crystal-like appearance of the paint film. The texture of the coating film is clear and sparkling, with unique visual effects, which can cover up the defects of the substrate. It has super decorative properties, smooth touch and strong la...

AI Technical Summary

Problems solved by technology

Therefore, the paint formula requires high accuracy, the construction procedure is complicated and difficult, the production efficiency is low, and the cost is high. It is not suitable for coating methods such as roller coating and dip coating, which has become a serious obstacle restricting the promotion of crystal pattern coatings in the packaging and printing industries.

[0005] In addition, the quality stability of crystal pattern paint is poor, easy to crust, and the storage time is short; and the prior art has added more raw tung oil and cobalt, manganese, etc. In addition, it has disadvantages such as strong odor during construction, easy yellowing of the coating film when baked at high temperature, poor processing performance, and does not meet the requirements of environmental protection.
