Problems solved by technology

At present, the wear resistance coefficient of PVC is low, and the anti-skid property is not good during use. At the same time, the color of PVC floor is single, and the decorative performance is poor.
In addition, the existing PVC floor may also release substances harmful to the human body, so the environmental protection is poor
For public places with high public security requirements, such as airports, hospitals, kindergartens, etc., there are technical problems such as use restrictions

Abstract

The invention discloses a wear-resistant coating of a polyvinyl chloride (PVC) floor, and relates to the technical field of wear-resistant materials. The wear-resistant coating is mainly prepared fromthe following raw materials in mass percent: 15%-60% of cationic polymeric compound, 0.5%-20% of cationic photoinitiator, 0-5% of auxiliary agent and 20%-75% of wear-resistant powder. The wear-resistant coating has the advantages that the wear-resistant coating of the PVC floor does not use any volatile organic solvents, undergoes UV curing after being scrape-coated with a comma scraper, can realize high-speed coating, and is suitable for printed PVC substrates. The wear-resistant coating of the PVC floor has fast curing speed; the cured coating has good adhesion, excellent wear resistance, agood appearance, and no odor. The PVC floor prepared by lamination of the wear-resistant coating and the PVC substrate by a hot-pressing compound process has excellent wear resistance and environmental protection performance, high tempering stability, and has good application prospects.

Description

technical field [0001] The invention relates to the technical field of wear-resistant materials, in particular to a PVC floor wear-resistant coating. Background technique [0002] PVC flooring is a new type of light-weight floor decoration material that is very popular in the world today. It has entered the Chinese market since the early 1980s, and has been generally recognized and widely used in large and medium-sized cities in China. Such as home interiors, hospitals, schools, office buildings, factories, supermarkets, shopping malls, stadiums and other places. PVC flooring is made of polyvinyl chloride and its copolymer resin as the main raw material, adding fillers, plasticizers, stabilizers, colorants and other auxiliary materials, on a sheet or a certain length of coil substrate, after coating or calendering , extrusion or extrusion process. PVC flooring is an environmentally friendly and fully recyclable material, which is of great significance in the context of my ...
