UV coating

Abstract

The invention relates to UV coating which belongs to the technical field of UV coating. The UV coating is characterized by comprising the following components in percent by weight: 28-32 percent of Sartomer hyperbranched multifunctional polyurethane resin, 8-12 percent of crylic acid graft modified acrylic resin, 28-32 percent of Sartomer crylic acid activated monomer, 4-6 percent of Ciba photoinitiator, 5-7 percent of UK700 flatting powder, 1.5-2.5 percent of US surface improving agent, 8-12 percent of accelerating agent and 3.5-5 percent of SDY modifying agent. The UV coating has environment protection, high temperature resistance, good film-forming hardness, good glossiness, good liquidity resistance and wear-resisting property, excellent yellowing resistance, long activation period, low coating cost, high efficiency and ten times of the conventional coating efficiency.

Description

technical field [0001] The invention relates to a coating, in particular to a UV coating. Background technique [0002] With the development of the economy and the continuous improvement of people's living standards and aesthetics, people are increasingly emphasizing the decoration effect and environmental protection requirements for the decoration of the living room or the production of furniture, and use it as one of the standards to measure the quality of the decoration. one. [0003] Traditional coatings are generally composed of oils, resins, pigments, solvents and additives. Volatile organic compounds (VOC) are often contained in solvents and additives, most of which are toxic, while the solvent content of solvent-based coatings generally exceeds 40% of the total mass of the coating, and some co-solvents must be added to adjust the viscosity during use. Most of the organic solvents are released into the air without participating in the reaction during construction. ...

Problems solved by technology

But at present, this kind of coating still has several major defects: it is easy to form cracks and white spots at the corners of wood products, it can only achieve flat curing, and there is an unpleasant smell escaping from the UV section of wood products.

At this time, the UV paint often acts as a magnifying glass, which further enlarges the coating defects (such as pitting), which is difficult to overcome.
