Abstract

The invention relates to modified unsaturated polyester resin and in particular relates to polishing-free highlight coating resin. The polishing-free highlight coating resin is characterized in that at least one air-dried monomer is introduced into unsaturated polyester and at least two photoinitiators, namely surface layer initiator photo-curing resin and deep layer initiator photo-curing resin respectively, are adopted. According to the polishing-free highlight coating resin, the air-dried monomer is introduced into the unsaturated polyester, multiple photoinitiators are adopted for playing a synergistic effect, and an ingenious formulation design is adopted, so as to obtain a polishing-free highlight coating, so that a polishing process is eliminated, the production efficiency is improved, the usage amount of resin is reduced, and the production cost is saved; furthermore emission of VOC (volatile organic compounds) is reduced while a photocuring process is adopted, thereby being consistent with the policy of building a resource-saving and environmentally-friendly society advocated in China.

Description

technical field [0001] The invention relates to a modified unsaturated polyester resin, in particular to a polishing-free high-gloss coating resin. Background technique [0002] Coating resin is widely used in the surface coating of wooden or plastic products such as pianos, high-end furniture, wooden handicrafts, etc. The process is simple, and the products made of it have good surface hardness and gloss, and play a protective and decorative role, so they are very useful. broad market. [0003] At present, there are three main systems for coating resin at home and abroad: [0004] 1. High-temperature baking coating resin, this resin system contains a large amount of solvent, after baking the solvent volatilizes into the atmosphere, causing pollution to the environment, although the coating resin that does not need to be polished can be obtained after curing, the hardness and fullness The effect is not very ideal. [0005] 2. The unsaturated coated polyester resin cured a...
