UV-curable wear-resistant primer

Abstract

The invention discloses UV-curable wear-resistant primer which comprises the following raw materials by weight: 40 to 50 percent of epoxy resin DYD, 4 to 6 percent of aromatic urethane acrylate, 15 to 20 percent of DPGDA, 2 to 3 percent of benzophenone, 10 to 15 percent of butyl acetate, 10 to 15 percent of modified nano-Al2O3, 5 to 10 percent of titanium dioxide, 0.5 to 0.8 percent of one or more antifoaming agents, 0.4 to 0.6 percent of one or more dispersing agents, and 1 to 1.5 percent of one or more thickening agents. The UV-curable wear-resistant primer has the advantages that as the volatility and the odor are low, the environmental pollution is low; as the hardness and the wear resistance are high, the service life of a material decorated by the primer can be effectively prolonged; the curing speed is fast, and the production efficiency is high; being cured at ordinary temperature, the primer is suitable for various base materials; energy is saved, that is, the energy consumption is about 1 / 5 of that of the conventional coating; the performance indexes, of a coating made of the primer, in all aspects, such as wear resistance, acid and alkali resistance, salt spray resistance and gasoline resistance, of an organic solvent are all very high.

Description

technical field [0001] The invention relates to a coating, in particular to a UV light-curing wear-resistant primer. technical background [0002] Ultraviolet (UV) curing coating and its coating technology are new surface treatment technologies emerging in the 1980s. Compared with the existing thermosetting coatings, this type of coating has the advantages of fast curing, energy saving, room temperature curing, less pollution, and superior coating performance. It is a new generation of green chemical products. Compared with coatings cured by traditional processes, UV-cured coatings show better wear resistance, so UV-cured wear-resistant primers have become one of the research hotspots in the field of UVCC. It can be used in building materials, sporting goods, electronic communications, optical devices, packaging materials, auto parts and other fields, and is a new material with broad application prospects. However, for a long time, the technology and product market of this...
