Abstract

An ultraviolet light curing coating for a PVC floor is prepared from components in parts by weight as follows: 0-40 parts of prepolymers, 0-15 parts of fluorine-containing resin, 15-25 parts of a reactive diluent, 1-10 parts of a photoinitiator, 15-30 parts of filler, 1-5 parts of a wetting dispersant and 1-5 parts of a defoaming agent. The ultraviolet light curing coating for the PVC floor is high in curing speed, good in permeability and excellent in scratch resistance and pollution tolerance. The wear-resisting filler is added, so that a coating system has outstanding wear resistance and the wear resistance of the PVC floor is remarkably improved; the wear-resisting filler is one or more of ceramic powder, aluminum oxide, calcium carbonate, silica powder, corundum, diamonds, glass micropowder and macromolecule wax. Some fluorosilicon resin is also added to the coating to greatly reduce the surface tension of the coating, and the dirt resistance of the system can be significantly improved. The dispersity and the levelling performance of the coating system can be remarkably improved, bubbles of the coating can be notably reduced, and a coating layer with excellent performance can be obtained after curing.

Description

technical field [0001] The invention relates to an ultraviolet light curing paint, in particular to an ultraviolet light curing paint for PVC floor and a preparation method thereof. Background technique [0002] PVC plastic floor is a substitute for traditional materials such as wood, marble, and granite. It has advantages that traditional materials cannot match, such as waterproof, non-slip, flame retardant, light weight, and simple laying. However, PVC itself has poor wear resistance, which makes the floor not wear-resistant and easy to get dirty. UV coating can greatly improve its wear resistance and stain resistance, and improve its quality. At present, UV curing coatings have become a relatively mature technology, especially with the improvement of people's awareness of environmental protection, production and researchers pay more attention to the development and application of UV curing coatings. UV-curable coatings fully comply with the "4E" principle. Generally, it...
