Abstract

The invention provides an ultraviolet-curing anti-cracking oil composition. The composition comprises the following components in percentage by weight: 40-70 percent of olefinic bond type unsaturated group-containing polyurethane-acrylate prepolymer, 10-40 percent of acrylate monomer, 2-8 percent of a chain transfer agent, 3-10 percent of a photoinitiator and 1-10 percent of an adhesion promoter, wherein the olefinic bond type unsaturated group-containing polyurethane-acrylate prepolymer is prepared from polytetrahydrofuran polyalcohol, polyisocyanate and hydroxyethyl acrylate serving as raw materials. The composition is cured under ultraviolet irradiation after being prepared according to a ratio; the obtained film is flat and smooth, has good adhesion, superior mechanical performance and elongation at break of being over 50 percent, can be used in place of a hot melt adhesive and is widely applied to bamboo high-density boards.

Description

technical field [0001] The invention belongs to the field of anti-cracking agents for high-density boards, and in particular relates to an ultraviolet light curing anti-cracking oil composition. Background technique [0002] Because of its room temperature curing, no VOC (volatile organic compound) emission, UV curing technology has the characteristics of green environmental protection, high efficiency and energy saving. Since entering the 21st century, its application field has been continuously expanded, with an annual growth rate of more than 10%. At present, UV curing technology has been widely used in bamboo and wood decorative panels, plastics, electronics and other fields. [0003] Bamboo resources are relatively abundant in my country, and the growth cycle of bamboo is short, generally 2 to 5 years. Bamboo is steamed at high temperature and formed under high pressure to produce high-density boards, commonly known as "heavy bamboo". Such materials are often required...
