Abstract

The invention relates to the field of coatings and particularly relates to an ultraviolet curing coating with low chromatic number, high gloss and high hardness for woodware. The ultraviolet curing coating with low chromatic number, high gloss and high hardness for woodware is prepared from the following raw materials in percentage by mass: 30-45% of a mixture of standard bisphenol A epoxy diacrylate and aliphatic polyurethane hexaacrylate, 3-5% of ethylcellulose, 5-12% of an initiator, 1-3% of a surface auxiliary, 5-10% of a cosolvent, 10-20% of an active diluent, 1-2% of a nanosilver antibacterial agent and 10-30% of ethanol. The ultraviolet curing coating provided by the invention further has the effects of higher corrosion resistance, aging resistance, good curing reaction and the like while having low chromatic number, high gloss and high hardness.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a low-color, high-gloss, high-hardness UV-curable coating for woodware. Background technique [0002] Since the advent of UV-curable coatings, it has the characteristics of 5E, namely Efficient, Enabling, Economical, Energy Saying, and Environmental-friendly. In the prior art, UV-curable coatings have been widely used in fields closely related to life to beautify and protect objects. [0003] The coating can effectively protect the wooden utensils from being corroded, thereby prolonging the service life of the wooden utensils. In addition, the wooden utensils appear more beautiful under the coating of the coating. However, the existing general wooden utensils have poor coating effects, and are not easy to be evenly coated, resulting in poor gloss of the coating film and the like. Contents of the invention [0004] The purpose of the present invention is to solve the defects of the pri...
