Antibacterial UV paint for PVC floor plastic

Abstract

The invention discloses antibacterial UV paint for PVC floor plastic. The antibacterial UV paint for the PVC floor plastic is prepared from, in percent by mass, 40-50% of photosensitive resin, 20-30%of a crosslinker, 5-10% of a photoinitiator, 1-5% of a leveling agent and 5-15% of additives, wherein the additives include an wear-resistant agent, an anti-corrosion agent and a reinforcing agent, the wear-resistant agent adopts silicon oxide particles, the anti-corrosion agent adopts carbon black particles, the reinforcing agent adopts graphite carbon fiber, and a preparation method of the photosensitive resin comprises the steps of: mixing a prepolymer with a diluent, performing even stirring, then adding polyhydroxyalkanoate, a photosensitizer and additives, heating and stirring the obtained mixture in a water bath of 40-50 DEG C, and performing vacuum pumping to obtain the photosensitive resin. According to the antibacterial UV paint for the PVC floor plastic, the additives are addedinto the targeted PVC floor plastic, wherein the wear resistance of the surface is improved greatly through the silicon oxide particles, the paint is isolated from the outside through the carbon blackmaterial so that bacteria cannot survive, and a network can be formed by the paint through the graphite carbon fiber so that the strength can be reinforced.

Description

technical field [0001] The invention relates to the technical field of wall painting, in particular to a PVC floor plastic antibacterial UV paint. Background technique [0002] Traditional coating curing usually removes the solvent in the polymer solution by heating, that is, physical drying, to obtain a hardened paint film. UV curing is to use the energy of ultraviolet light to initiate the polymerization and crosslinking reaction between the low-molecular prepolymer or oligomer in the coating and the monomer molecule as a reactive diluent to obtain a hardened paint film. Chemical bonds enable chemical drying. [0003] PVC plastic floor is a new type of light-weight ground decoration material that is very popular in the world today, also known as light-weight ground material. It is a popular product in Europe, America, Asia, Japan and South Korea, and it is popular abroad. PVC plastic flooring has two types: polyvinyl chloride coiled flooring and polyvinyl chloride bloc...

Problems solved by technology

[0004] In order to further improve the performance of PVC plastic flooring, such as wear resistance and antibacterial properties, it is necessary to spray coatings on its surface, while traditional coatings cure slowly, while UV-cured coatings perform poorly in terms of wear resistance and antibacterial properties.
