Abstract

The invention relates to a high-hardness and high-gloss ultraviolet light polymerization coating used for PVC floor tiles. The coating is prepared and characterized by comprising the raw materials in percentage by mass: 30-45% of a mixture of aliphatic polyurethane diacrylate and photosensitive phenolic aldehyde epoxy acrylate, 3-5% of graphitized nano carbon fiber, 5-12% of an initiating agent, 1-3% of a surface assisting agent, 5-10% of a cosolvent, 10-20% of a reactive diluent, 1-2% of a polyacrylate or organosilicone leveling agent, 10-30% of an inert solvent and 0-2% of pigment. The coating provided by the invention has the performances of high hardness, high tenacity and high gloss, and besides, is further provided with higher salt fog resistance, ageing resistance, wearing resistance, scratch resisting capability, adhesive force, and cold and hot impact capacity.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a high-hardness, high-gloss ultraviolet light curing coating for PVC floor tiles. 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.
