Problems solved by technology

This type of paint is applied by spraying, which has low efficiency, long drying time, high cost, pollutes the environment, and affects the health of construction workers.
The hardness of the traditional solvent-based paint film is about 2H, the wear resistance is poor, the wear rate (g / 100r) is higher than 0.15, the scratch resistance, the paint film is poor in stain resistance, and it is difficult to clean with oily colors. The surface is easily damaged in daily life

Abstract

The invention discloses a graphene ultraviolet UV photo-curing white coating which comprises the following raw material components in parts by weight: 20-30 parts of UV cured organic silicon resin, 10-20 parts of UV cured bisphenol A epoxy acrylate resin, 5-10 parts of ethylene glycol dimethacrylate, 5-10 parts of tripropylene glycol diacrylate, 5-10 parts of 2,4,6-trimethylbenzoyl diphenyl phosphine oxide, 3-5 parts of 1-hydroxy-cyclohexyl phenyl ketone, 5-10 parts of a graphene oxide powder, 1-3 parts of a moistening dispersing agent, 1-3 parts of an ultraviolet absorber, 10-20 parts of aluminum oxide, 10-20 parts of titanium dioxide, 1-3 parts of an anti-mold antibacterial agent and 1-3 parts of fluorine aids. Under the action of ultraviolet light, the white coating can be instantaneously cured into a membrane, is good in stain and weather resistance, free of organic volatile matter, free of environment pollution and green and environmental-friendly, and can be applied to decorationplates of projects such as tunnels and indoor and outdoor engineering.

Description

technical field [0001] The invention relates to a composition and a preparation method of a graphene ultraviolet UV light-cured white coating, which belongs to the technical field of coatings and paints. Background technique [0002] The paints used for a long time in industries such as decorative plates, calcium-silicon boards, and tunnel engineering are mainly traditional solvent-based epoxy floor paints and solvent-based zinc-rich primers and anti-rust paints. This type of paint is applied by spraying, which has low efficiency, long drying time, high cost, pollutes the environment, and affects the health of construction workers. The hardness of the traditional solvent-based paint film is about 2H, the wear resistance is poor, the wear rate (g / 100r) is higher than 0.15, the scratch resistance, the paint film is poor in stain resistance, and it is difficult to clean with oily colors. It is easy to damage the surface in daily life. Secondly, solvent-based coatings contain ...
