Abstract

The invention relates to the technical field of ultraviolet curing coatings, and particularly relates to an ultraviolet curing coating formula for eliminating formaldehyde in air and a preparation technology thereof. The coating consists of the following components in percentage by weight: 20-40% of urethane acrylate, 10-30% of 1,6 hexanediol diacrylate, 1-10% of trimethylolpropane triacrylate, 1-5% of 2-phenoxy ethyl acrylate, 1-5% of dispersing agent, 2-6% of superfine silicon dioxide, 1-4% of superfine aluminum oxide powder, 1-12% of matte powder, 1-4% of wax powder, 4-6% of 2-hydroxyl-2-methyl-1-phenyl-1-acetone, 0.1-2% of surface aid and 1-15% of formaldehyde removal aid. The preparation technology of the coating comprises the steps of sequentially feeding the raw materials and stirring for uniformly mixing. Through the formula and the technology provided by the invention, the prepared coating is applicable to the fast operation of a factory production line, and also has the protection functions such as good adhesion, scratch resistance and the like.

Description

【Technical Field】 [0001] The invention relates to the technical field of ultraviolet curing coatings, in particular to an ultraviolet curing coating with the function of eliminating formaldehyde in the air for coating the surface of decorative boards such as wood, plastic, metal and the like. 【Background technique】 [0002] Formaldehyde is a volatile organic compound. It is colorless, has a special smell, is slightly heavier than air, and is easily soluble in water. Formaldehyde has an important effect on human health, and has a strong irritating effect on the eyes, respiratory tract, human mucous membranes and skin; acute poisoning can cause symptoms such as tearing, runny nose, cough, etc., triggering a variety of respiratory diseases; chronic inhalation of low concentrations can cause persistent headaches , Weakness, insomnia, etc.; long-term skin contact can cause dermatitis, adversely affecting the human respiratory system, digestive system and central nervous system, causin...
