Abstract

The invention belongs to the technical field of UV paints, and provides a super-yellowing-resistant high-rigidity UV fully-bright transparent finishing coat and a preparation method thereof. The super-yellowing-resistant high-rigidity UV fully-bright transparent finishing coat consists of the following raw materials in parts by weight: 20-40 parts of bisphenol A epoxy acrylate, 10-20 parts of amino-modified epoxy acrylate, 20-40 parts of an acrylate monomer, 3-5 parts of a photoinitiator and 0.5-2 parts of additives, wherein the acrylate monomer consists of isobornyl acrylate, neopentyl glycoldiacrylate and tri(2-hydroxyethyl)isocyanurate triacrylate in a mass ratio of (0.1-0.6) to 1 to (0.8-2); and the additives are one or more of a defoamer, a wetting agent, a dispersing agent and an anti-settling agent. The super-yellowing-resistant high-rigidity UV fully-bright transparent finishing coat has good plumpness, adhesive force and pollution resistance, excellent yellowing resistance and high rigidity and can be applied to 3D printing patterns on dining tables, tea tables and the like.

Description

technical field [0001] The invention relates to the technical field of UV paint, in particular to a super-yellowing-resistant high-hardness UV full-bright transparent topcoat and a preparation method thereof. Background technique [0002] With the improvement of people's awareness of environmental protection, the use of non-renewable raw materials such as wood and stone is less and less. Therefore, the countertops of dining tables and coffee tables are increasingly replaced with renewable raw materials such as glass and synthetic stone. . At present, young people have become the mainstream consumer group, and they prefer products such as dining tables and coffee tables with simple patterns and single colors. The use of 3D printing technology to prepare patterns on dining tables, coffee tables, etc. has the advantages of environmental protection, high efficiency, uniform color, etc., and can meet the consumption needs of young people, so it is widely used. [0003] In order...
