Abstract

The invention relates to ultraviolet cured high-anti-fouling matte floor paint. The ultraviolet cured high-anti-fouling matte floor paint comprises the following raw materials: modified polyurethane acrylate resin, polyester acrylate resin, bifunctional group active monomers, three-functional group active monomer, four-functional group active monomer, a flatting agent, a defoaming agent, a dispersing agent, an initiator, matting powder and modified polytetrafluoroethylene powder. The preparation method comprises the following steps: (1) preparing a raw material; (2) dispersing the raw material; (3) adding the initiator; and (4) filtering and packaging. A paint film of the invention is semi-transparent, the glossiness is 6 to 8, the ultraviolet cured high-anti-fouling matte floor paint belongs to the matte floor paint and contains no organic solvent, has excellent anti-fouling performance, seepage resistance and corrosion resistance, good toughness, adhesion, wear resistance and scratchresistance, and can compensate the blank of the domestic matte floor paint market; the preparation method is simple in procedures, high in operability, and easy in mass production; the conventional pollution source mark can be easily cleaned after being dried; and the requirement of customers for individual high-end floor paint can be met.

Description

Technical field [0001] The invention relates to the technical field of coatings, and relates to ultraviolet (UV) curing coatings, specifically, a UV curing high stain resistance matt floor coating and a preparation method thereof. Background technique [0002] Ultraviolet (UV) curing paint is a kind of paint that appeared in the 1970s. Its advantages are: fast curing speed (0.1~10s), excellent coating performance, heat-sensitive substrates can be painted, and energy saving (about Thermal curing materials consume 1 / 5~1 / 10) of energy consumption, no solvent discharge, safety and no pollution to the environment, less floor space, very suitable for automatic assembly line coating. [0003] Ultraviolet light-curable coatings stimulate and decompose the photoinitiator in the coating when UV light is irradiated to the photo-curable coating to generate free radicals, and the active free radicals then hit the double bonds in the coating and react to form extended chains. This reaction will...
