Embodiment Construction

[0020] A kind of water droplet layer technological process, it is characterized in that: comprise the following steps:

[0021] 1) Electrostatically dedust the workpiece;

[0022] 2) Pre-treat the workpiece after electrostatic dust removal: when the material of the workpiece is polypropylene, use blue flame for hair removal treatment, and when the material of the workpiece is ABS or AS, perform spraying and degreasing treatment;

[0023] 3) Spray UV vacuum coating primer on the pre-treated workpiece;

[0024] 4) Place the workpiece after spraying the UV vacuum coating primer in a far-infrared drying tunnel with a temperature of 55±5 degrees for leveling;

[0025] 5) Place the leveled workpiece under an ultraviolet lamp with an output power of 900-1000 mJ for 5-10 seconds to cure the vacuum coating primer;

[0026] 6) Place the workpiece after curing of the vacuum coating primer in a vacuum environment with a vacuum degree of 0.072Mpa for coating;

[0027] 7) Take out the co...

Abstract

The invention discloses a technological process of a water droplet pattern layer. The technological process comprises the following steps: conducting electrostatic dust removal and pretreatment on a workpiece in sequence; spraying ultraviolet vacuum coating primer on the workpiece; carrying out levelling; irradiating the workpiece with an ultra-violet lamp to cure a vacuum coating primer; placing the workpiece in a vacuum environment for coating after the vacuum coating primer is cured; taking out the workpiece; carrying out dust removal again; spraying an ultraviolet vacuum coating finishing coat; carrying out secondary levelling on the workpiece sprayed with the ultraviolet vacuum coating finishing coat; irradiating the workpiece with the ultra-violet lamp again to cure the vacuum coating finishing coat; spraying an ultraviolet vacuum coating colored finishing coat; carrying out secondary spraying of the ultraviolet vacuum coating finishing coat; carrying out tertiary levelling; irradiating the workpiece with the ultra-violet lamp to cure the vacuum coating finishing coat to obtain a finished product. The optical curing coating and vacuum coating technology are used for changing the surface coating effect of a cosmetic container to ensure that the coating looks like water droplets, and the container looks more bright and high-end.

Description

technical field [0001] The invention relates to a coating layer, in particular to a water drop layering process flow. Background technique [0002] Surface treatment is a method of artificially forming a surface layer on the surface of a base material with mechanical, physical and chemical properties different from that of the base. The purpose of surface treatment is to meet the corrosion resistance, wear resistance, decoration or other special functional requirements of the product. However, in the general painting process, affected by the air pressure value output by the air compressor, the effect of water droplets on the surface is uneven, or the phenomenon of different sizes occurs, and it is impossible to make a perfect water drop effect layer. Contents of the invention [0003] The purpose of the present invention is to provide a water drop coating process, which has the advantages that the coating effect can achieve the water drop effect, so that the appearance ...
