Problems solved by technology

However, its paint film has a certain degree of transparency, low gloss, and the visual effect of grain texture is not obvious
In addition, due to the unsatisfactory drying degree of the crystalline paint film, once the volatile spillage is released by heat, it is easy to destroy the structure of the film layer covering it, reducing the firmness and gloss
Moreover, the crystalline lacquer is used as a topcoat, and its paint film has low strength and poor solvent resistance, and it is easy to peel off and decolorize when in contact with alcohol, perfume, etc.

Abstract

A bottom material surface processing technology enabling a surface to have crystal flower lines comprises the following steps of (1) bottom material preprocessing, wherein bottom material surface oil stain and dust are cleared, and drying is carried out; (2) crystallization paint coating, wherein the clean bottom material surface is coated with crystallization paint of a crystallization type; (3) solidification and crystallization, wherein standing in room temperature is carried out for 30-40 minutes for solidification and crystallization; (4) paint film drying, wherein bottom materials are placed in a drying oven with the preset temperature of 70-100 DEG C for drying for 30-90 minutes; (5) vacuum coating, wherein a metal film is arranged on a crystallization paint film in a vacuum-evaporation mode; (6) finishing paint coating, wherein ultraviolet light curing finishing paint is arranged in the metal film in a coating mode; and (7) finishing paint solidification, wherein the paint film is solidified through ultraviolet irradiation for 5-10s. According to the technology, the metal film is arranged on the crystallization paint film in a vacuum-evaporation mode successfully, the crystal flower lines high in glossiness are obtained, the finishing paint is arranged on the metal film in a coating mode to be used as a protecting layer and a coloring layer, and the obtained paint film is bright in color, high in strength and good in solvent resistance.

Description

technical field [0001] The invention relates to a substrate surface treatment process for making the surface have crystal texture. Background technique [0002] Crystalline crystalline paint contains crystalline substances such as naphthalene, phthalic anhydride, and urea. After coating, the solvent evaporates, and a paint film with crystal texture can be obtained. However, its paint film has a certain degree of transparency, low gloss, and the visual effect of crystal texture is not obvious. In addition, due to the unsatisfactory drying degree of the crystalline paint film, once the volatile spillage is released by heat, it is easy to destroy the structure of the film layer covering it, reducing the firmness and gloss. Moreover, the crystalline lacquer is used as a topcoat, and its paint film has low strength and poor solvent resistance, and it is easy to peel off and decolorize when in contact with alcohol, perfume, etc. Contents of the invention [0003] A technical ...
