Abstract

The invention discloses a wear-resistant and stain-resistant ultraviolet curing PVC (polyvinyl chloride) floor coating. The coating is prepared from the following raw materials in parts by weight: 50 to 70 parts of polyurethane acrylate oligomer, 20 to 50 parts of reactive diluent, 10 to 15 parts of matt powder, 1 to 5 parts of photoinitiator, 0.3 to 5 parts of fluorine-containing hyperbranched polythionocarbamate and 1 to 2 parts of additive. The fluorine-containing hyperbranched polythionocarbamate added in the invention not only reduces the internal stress and curing shrinkage of a system and enhances the adhesive force with a base material, but also improves the crosslinking density, hardness and wear resistance of the coating by introducing a rigid polythionocarbamate structure.

Description

technical field [0001] The application of the present invention relates to the technical field of light-cured coatings, in particular to a wear-resistant and anti-fouling UV-cured PVC floor coating. Background technique [0002] Ultraviolet curing (UV) coatings are a new type of environmentally friendly coatings. Compared with traditional heat curing, UV light curing technology has the "5E" characteristics of high efficiency, fast speed, environmental protection, energy saving and wide adaptability. Urethane acrylate is an important light-curable oligomer because of the diversity of its structure selection, which can synthesize oligomers with set properties through molecular design. In recent years, with the continuous improvement of people's living standards, wear-resistant and anti-fouling UV-curable PVC floor coatings have received extensive attention. [0003] At present, the application of PVC floor coatings in China is gradually becoming popular, and it is widely use...
