High-hardness and high-gloss ultraviolet light polymerization coating used for PVC floor tiles

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. In the prior art, UV-curable coatings have been widely used in fields closely related to life to beautify and protect objects.

[0003] Plastic building materials are a rising star in the building materials industry. With the rapid growth of China's real estate industry and increased investment in infrastructure in recent years, China's plastic building materials industry has become the second largest in the plastics industry after packaging. A pillar industry with an average annual growth rate of more than 15%. In recent years, China's plastic building materials industry has accelerated the pace of research and developme...
