Problems solved by technology

[0003] In the coating process, the level of light energy will have a great impact on the quality of the coating film.
Too low light energy will affect the cross-linking density of the coating film, resulting in insufficient reaction of the coating film, leaving more cross-linking double bonds that did not participate in the reaction, which eventually leads to too low molecular weight of the film, which leads to poor chemical performance of the coating film. reduce
Similarly, the coating film of the final product will soften during the heat resistance test, which will cause disturbance of the aluminum coating layer and occurrence of colorful and other undesirable problems.
[0004] On the other hand, the production lines of some car lamp processing manufacturers have the problem of unstable or low light energy
The reason for this may be that the lamps of various substrates are processed on the same production line at the same time, and the heat resistance of some substrates such as ABS parts is only about 70°C, and deformation will occur when the temperature is too high, so only Can be processed with lower light energy

Abstract

The invention provides a high-temperature resistant UV (Ultraviolet) coating material for vacuum plating. The high-temperature resistant UV coating material is prepared from the following ingredients in percentage by mass: 45-65% of prepolymer, 10-25% of reactive monomer, 2-8% of photoinitiator, 0.1-3% of leveling agent and 10-35% of organic solvent. Correspondingly, the invention also provides a preparation method for the coating material. The preparation method comprises the following steps: (a) isolating ultraviolet rays, and carrying out lighting by adopting a yellow-light lamp; (b) thoroughly dissolving the initiator with the organic solvent, and carrying out uniform stirring; and (c) sequentially adding the monomer of a formula amount, the prepolymer of a formula amount and the leveling agent of a formula amount in order under the condition of keeping stirring, and then, carrying out uniform stirring, thereby completing the preparation of the UV coating material. The invention further provides application of the high-temperature resistant UV coating material for vacuum plating. The coating material is coated on a base material, leveling is carried out for 1-2 minutes so as to thoroughly spread and level a coating film, infrared preheating is carried out for 3-5 minutes at the preheating temperature of 50 to 120 DEG C, then, UV irradiation curing is carried out, and the light radiation energy is 2,000-3,500mJ / cm<2>.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a high-temperature-resistant vacuum electroplating UV coating and a preparation method and application thereof. Background technique [0002] The use of UV coatings for vacuum plating primers is already a very common technology. It is used in cosmetics, toys, accessories, 3C and other industries. The vacuum plating primers for car lights have very high requirements for heat resistance, and the substrates are also relatively high. Complicated, the common ones are ABS, PC, BMC, PBT, PPS, aluminum alloy, electrophoretic metal parts, etc. The heat resistance requirements of different substrates are also different. ABS heat resistance is 80 ° C, PC heat resistance is 120 ° C, BMC, PBT, PPS, aluminum alloy, and electrophoretic metal parts can withstand heat up to 180°C. Therefore, how to meet the heat resistance requirements of different materials and at the same time have the adhesi...
