Abstract

The invention discloses a coating primer for the spotlight cover of an electric vehicle lamp, which comprises the following raw materials in parts by weight: 10-50 parts of modified alkyd resin, 20-50 parts of modified phenolic resin, and 20-40 parts of solvent , 0.8-3 parts of drying agent, 0.005-0.015 parts of silicone oil, and 0.1-0.3 parts of anti-skinning agent. The coating primer provided by the invention for the spotlight cover of an electric vehicle lamp has stable performance, no pollution, reasonable formula and excellent performance. In the selection of the formula, factors such as leveling and adhesion are fully considered, and two film-forming resins, modified alkyd resin and modified phenolic resin, are used for compounding. The prepared primer has excellent leveling performance and durability. Thermal performance, fast drying speed, no shrinkage cavity and waviness, can ensure high gloss and refractive index of metal coating. The synergistic effect of various components in the formula makes the paint film have excellent adhesion to ABS substrates, good film-forming hardness, and the coating has no loss of gloss and wrinkling.

Description

technical field [0001] The invention relates to the field of new paint materials, in particular to a coating paint for a condenser cover of an electric vehicle lamp and a preparation method thereof. Background technique [0002] In recent years, with the development of the economy, plastics (ABS, GRP, RIM, EPPM, polyurethane, nylon) as engineering decorative structural materials are widely used in industrial fields such as automobiles, household appliances, daily packaging and craft decoration. In the industry, vacuum evaporation plating and vacuum sputtering plating are usually used to form a bright metal film on the surface of the plastic substrate, that is, metallization of the plastic surface. Vacuum coating on plastic products can endow plastic products with metallic luster, increase the appearance aesthetics, and increase added value at the same time. This technology is widely used especially in the field of car lamp reflectors. [0003] The vacuum-plated metal thin f...
