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 comprises a vacuum coating primer and a vacuum coating finish paint. The vacuum coating primer comprises high-hydroxyl-value low-viscosity acrylic resin, multi-element thixotropic hydroxyl-containing acrylic resin, a diluent, an adhesion promoter, a leveling agent, a drier, an oily nano color concentrate and an aliphatic or alicyclic polyisocyanate curing agent. The vacuum coating finish paint comprises low-hydroxyl-value acrylic resin, a diluent, an adhesion promoter, a leveling agent, an antifoaming agent, an ultraviolet absorber, a drier, an oily nano color concentrate and an aliphatic or alicyclic polyisocyanate curing agent. The acrylic vacuum coating paint has the advantages of high weather resistance, favorable acid / alkali resistance, favorable water resistance, favorable sag resistance, excellent mirror surface effect and favorable stability, has excellent decorative and protective actions on acrylic, and can satisfy the requirements for acrylic vacuum coating products in outdoor, bathroom and other places.

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...
