Abstract

The invention relates to an ultraviolet (UV) cured paint. The UV cured paint is prepared from the following raw materials in part by weight: 50-60 parts of epoxy acrylate, 20-25 parts of methacrylate, 6-8 parts of 2-hydroxyl-2-methyl-propiophenone, 10-12 parts of dimethylaminoethyl methacrylate, 1-2 parts of polyoxyethylene stearate, 10-12 parts of dipentaerythritol hexaacrylate, 3-5 parts of ethylene glycol monoethyl ether acetate, 1-2 parts of a silane coupling agent KH-550, 3-4 parts of an accelerator DM, 2-3 parts of acrylic acid-4-polyhydroxybutyrate, 1-2 parts of glycidyl methacrylate, 2-3 parts of bis tetradecene ester, 1-2 parts of an antioxidant DSTP (disteaxylthiodipropionate), and 4-5 parts of a dispersing aid. The UV paint is suitable for priming paints of hardware, zinc alloy, aluminium alloy, stainless steel, and vacuum plating coating UV, has lasting performance and strong universality, and meets the ROHS (Restriction Of Hazardous Substances) requirements.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to an ultraviolet light curing UV coating and a preparation method thereof. Background technique [0002] With the development of the market economy, great changes have taken place in the field of coatings. Among them, UV coatings have the advantages of fast curing speed, energy saving, room temperature curing, superior performance, and environmental protection. The surface is strong and heat-resistant, and the refraction effect is good, so that the substrate has a strong sense of subject. It has been widely used in chemical industry, machinery, electronic light industry, communication and other fields. Due to its environmental protection advantages, UV curing has received strong support from relevant environmental regulations and close attention from the industry. While the market demand for UV radiation curing materials is growing rapidly, UV radiation curing systems are being ...
