Antibacterial and flame-retardant ultraviolet curing matte finish paint

Abstract

The invention discloses antibacterial flame-retardant ultraviolet curing matte finish paint, which comprises the following raw materials: 10-20 parts by weight of epoxy acrylic resin, 10-20 parts by weight of flame-retardant acrylic resin, 30-50 parts by weight of an acrylate monomer, 3-5 parts by weight of a photoinitiator, 0.5-3 parts by weight of an antibacterial agent, 10-20 parts by weight of matting powder, and 1-2 parts by weight of an auxiliary agent. The preparation method comprises the steps of adding 10-20 parts by weight of epoxy acrylic resin, 10-20 parts by weight of flame-retardant acrylate, 15-25 parts by weight of an acrylate monomer and 1-2 parts by weight of an auxiliary agent, uniformly stirring, adding 3-5 parts by weight of a photoinitiator, 10-20 parts by weight of matting powder and 0.5-3 parts by weight of an antibacterial agent, and dispersing at a high speed, finally, adding the residual acrylate monomer, continuously stirring until the materials are completely and uniformly mixed, and keeping in a dark place. According to the embodiment of the invention, the finish paint can be instantly cured under ultraviolet rays, is used on a floor roller coating assembly line, meets the requirements of combustion performance grades of decoration materials on hardness, adhesive force, scratch resistance and wear resistance, and has antibacterial and bacteriostatic functions.

Description

technical field [0001] The invention relates to the field of composite coatings, in particular to an antibacterial and flame-retardant UV-curable matte finish, which is mainly used for surface coating of solid wood floors and solid wood composite floors. Background technique [0002] At present, the commonly used coatings for solid wood floors and solid wood composite floors are mainly ultraviolet curing (UV) coatings, photosensitive resins containing unsaturated double bonds, such as unsaturated polyester, epoxy acrylate, polyurethane acrylate, polyester acrylate , polyether acrylate, etc. The flame retardancy of these photosensitive resins is generally poor, and cannot meet the requirements of GB 50222-2017 "Code for Fire Protection Design of Building Interior Decoration", so they cannot be used in airports, stations, gymnasiums, shopping malls, restaurants, hotels, hospitals, schools , offices and other public places.

Problems solved by technology

The flame retardancy of these photosensitive resins is generally poor, and cannot meet the requirements of GB 50222-2017 "Code for Fire Protection Design of Building Interior Decoration", so they cannot be used in airports, stations, gymnasiums, shopping malls, restaurants, hotels, hospitals, schools , offices and other public places

[0003] These public places are crowded with people, easy to breed bacteria, enrich pollutants, etc., and also need to improve antibacterial ability to protect the health of the people
