Abstract

The ultraviolet-cured high-stain-resistance wear-resistant matt floor coating is prepared from the following raw materials: modified urethane acrylate resin I and modified urethane acrylate resin II,tri-, tetra- and hexa-functional active monomers; leveling agents I and II; a defoamer; a dispersant; an initiator; extinction powder I and extinction powder II; nano silicon carbide powder; and nanosilicon nitride powder. Herein, the paint film is a semitransparent paint film, wherein the thickness of a dry film is about 10 microns, and the dry film can be completely cured within 10 seconds, andthe glossiness of the paint is below 3 degrees. The paint belongs to a matt coating and the abrasion index is within 6 mg, so that polluted common colors or marks in life on a paint film can be easily wiped off, no trace is left, and the paint has good performance of high stain resistance and high abrasion resistance; in addition, and the floor coating does not contain organic solvents, is environment-friendly and healthy, and can meet the requirements of customers on personalized high-end floor coatings.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to ultraviolet (UV) curable coatings, in particular to UV curable matt floor coatings with high stain resistance and abrasion resistance. Background technique [0002] Ultraviolet (UV) curing coating is a coating that appeared in the 1970s. Its advantages are: fast curing speed (0.1-10s), excellent coating performance, heat-sensitive substrates can be coated, and energy saving (approx. 1 / 5 to 1 / 10 of the energy consumption of heat-curing materials), no solvent emissions, safe and non-polluting, small footprint, very suitable for automatic assembly line coating. [0003] UV-curable floor coatings are one of the UV-curable coatings. With the deepening of research on UV-curable floor coatings and the promotion of applications, people have higher and higher demands on the performance and functions of UV-curable floor coatings. Abrasion-resistant matt UV-cured high stain-resistant flo...
