Abstract

The invention discloses electric vehicle light snoot coating primer which is prepared from the following raw materials in parts by weight: 10-50 parts of modified alkyd resin, 20-50 parts of modifiedphenolic resin, 20-40 parts of solvent, 0.8-3 parts of a dryer, 0.005-0.015 part of organic silicone oil and 0.1-0.3 part of an anti-skinning agent. The electric vehicle light snoot coating primer provided by the invention has the advantages of stable performance, no pollution, reasonable formula and good performance. The formula is selected while taking full account of factors such as leveling property and adhesion; two kinds of film forming resin, the modified alkyd resin and the modified phenolic resin, are adopted and compounded; the prepared primer has excellent leveling property and heatresistance as well as high drying speed, prevents the generation of shrinkage cavity and ripples and can ensure high gloss and refractive index of a metal coating. Through a synergistic effect of various kinds of components in the formula, a film has excellent adhesion to ABS base material and good film forming hardness while the phenomena of gloss loss and wrinkling of the coating are avoided.

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...
