Abstract

The invention provides a vacuum plating UV base coat. The base coat comprises, by weight, 40-60 parts of bis-functional polyurethane acrylic resin, 40-60 parts of epoxy acrylic resin, 10-15 parts of reactive diluent, 1-5 parts of photoinitiator, 5-20 parts of butyl acetate cellulose solution, 140-160 parts of organic solvent and 5.3-20.5 parts of other auxiliaries. According to the base coat, themoisturizing performance on plastic substrates of the vacuum plating UV base coat can be significantly improved through the mutual action of the epoxy acrylic resin and the butyl acetate cellulose solution, the base coat particularly has a better moisturizing effect on the plastic substrates with residual demolding agent, the surface coating performance of the vacuum plating UV base coat can be ensured when demolding agent removing process on the plastic substrates is not conducted to allow the base coat has excellent adhesion force, and the problems of the influence on the base coat and plastic substrate coating quality due to residual demolding agent, lengthening production line, increasing production cost, high rejection rate of products and the like are solved.

Description

technical field

[0001] The invention relates to the technical field of vacuum electroplating UV primer, in particular to a vacuum electroplating UV primer 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 order to improve the surface decoration of plastic products, in order to make metal effects like gold, silver and copper, the industry usually adopts vacuum evaporation plating and vacuum sputtering plating to form a bright layer on the surface of plastic substrates. Metal film, that is, the metallization of the plastic surface.

[0003] Before vacuum evaporation plating or vacuum sputtering metal film coating on plastic substrates, the plastic substrates are primed to improve the quality o...

Examples

preparation example Construction

[0022] A preparation method for vacuum electroplating UV primer, comprising the steps:

[0023] (1) Stir and mix the difunctional polyurethane acrylic resin, epoxy acrylic resin, reactive diluent and some organic solvents;

[0024] (2) After the step (1) is completed, add photoinitiator, butyl cellulose acetate solution, other auxiliary agents and remaining organic solvent for stirring and mixing treatment.

[0025] Further, the preparation method of vacuum electroplating UV primer comprises the steps:
