Problems solved by technology
The traditional vacuum coating coatings are mostly urethane oil (primer) / thermoplastic coating (top coat) combination or UV coating, but urethane oil is easy to yellow, and the overall performance of thermoplastic coatings is average, while UV coating itself needs ultraviolet light to cure. Coupled with the presence of photoinitiators and photoinitiation accelerators, it is easy to cause photo-induced oxidative degradation and poor weather resistance. Therefore, traditional urethane oils and general UV coatings are not suitable for outdoor applications that require high weather resistance. Bathrooms and other places
In addition, acrylic is mostly a plate or sheet, which is more demanding on the sag resistance of the coating and large-area coating.
Therefore, there is currently a lack of a coating that has strong weather resistance, can be sprayed on a large area, and can be used for acrylic vacuum coating.

Abstract
The invention discloses an acrylic vacuum coating paint and a coating process thereof. The acrylic vacuum coating paint includes a vacuum coating primer and a vacuum coating top coat, and the vacuum coating primer includes a high-hydroxyl value low-viscosity acrylic resin and multi-component thixotropic hydroxyl-containing acrylic acid. Resin, diluent, adhesion promoter, leveling agent, drier, oily nano color essence and aliphatic or alicyclic polyisocyanate curing agent; vacuum coating topcoat including low hydroxyl value acrylic resin, thinner, adhesion Accelerators, leveling agents, defoamers, UV absorbers, driers, oily nano-color concentrates, and aliphatic or cycloaliphatic polyisocyanate curing agents. The acrylic vacuum coating coating has strong weather resistance, good acid and alkali resistance, good water resistance, good sag resistance, excellent mirror effect, good stability, has excellent decorative and protective effects on acrylic, and can meet outdoor, bathroom, etc. The site's requirements for acrylic vacuum coating products.
Description
technical field [0001] The invention relates to the technical field of chemical coatings, in particular to an acrylic vacuum coating coating and a coating process thereof. Background technique [0002] Acrylic, also known as plexiglass, is an important plastic polymer material developed earlier. It has extremely high transparency, chemical stability and weather resistance. It is widely used in construction, advertising signs, bathroom appliances and other fields. Acrylic has excellent processing performance, and its vacuum coating can give plastic products a metallized appearance and increase the added value of the product. The traditional vacuum coating coatings are mostly urethane oil (primer) / thermoplastic coating (top coat) combination or UV coating, but urethane oil is easy to yellow, and the overall performance of thermoplastic coatings is average, while UV coating itself needs ultraviolet light to cure. Coupled with the presence of photoinitiators and photoinitiatio...
