Problems solved by technology

At present, vacuum coating UV-curable coatings are generally realized by the process of oil-based primer→coating→color-adding medium paint→oil-based topcoat. However, oil-based coatings have disadvantages such as excessive VOC, not environmental protection, and greater skin irritation, which cannot meet the relevant requirements. Legal requirements; existing water-based coatings are difficult to meet performance requirements such as glossiness of vacuum coating

Abstract

The invention discloses a coating composition and application thereof. The coating composition comprises a primer and a finish paint. The primer is prepared from the following raw materials: an acrylate emulsion with functionality of 6-8, an acrylate emulsion with functionality of 2-4 and a water-based alkoxylation UV monomer; and the finish paint is prepared from the following raw materials: aliphatic acrylic emulsion with the functionality of 8-12, epoxy modified polyurethane acrylic emulsion with the functionality of 2-4, anionic carboxylic acid modified acrylate emulsion and an adhesion promoter. According to the coating composition provided by the invention, by adjusting the composition of the primer and the finish paint in the coating composition, the coating composition can meet the requirements of vacuum coating.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a coating combination and its application. Background technique [0002] In order to make the plastic surface have the luster and brightness of metal, it is generally realized by vacuum coating process. At present, vacuum-coated UV-curable coatings are generally realized by the process of oil-based primer→coating→color-adding primer→oil-based topcoat. However, oil-based coatings have disadvantages such as excessive VOC, environmental protection, and greater skin irritation, which cannot meet the relevant requirements. Legal requirements; existing water-based coatings are difficult to meet performance requirements such as glossiness of vacuum coating. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems in the above-mentioned prior art. For this reason, the present invention proposes a kind of paint combinat...
