Abstract

The invention discloses a preparation method of high-wear-resistance UV matte paint, comprising the steps of S1, mixing well a photosensitive monomer, a photoinitiator, a dispersant and a defoaming agent, allowing standing until foam completely disappears to obtain mixed liquid A; S2, adding matte powder and matte wax into the mixed liquid A of step S1, fully wetting the powder, adding a photosensitive prepolymer and a leveling slipping agent, and mixing well at a high speed to obtain mixed liquid B; S3, mechanically grinding the mixed liquid B of step S2, and dispersing to obtain mixed liquidC; S4, stirring well the mixed liquid C of step S3 at a high speed to obtain the high-wear-resistance UV matte paint. Stirring and pre-dispersing are performed under low viscosity, low speed and lowfoam before high-speed stirring and grinding, and high-speed stirring is finally performed; the dispersing mode above helps effectively solve the problems that, for instance, powder easily thickens again after dispersing and the power has a large distribution range of particle size. Preparation of the coating herein employs a high-energy high-speed curing process under nitrogen protection; the insufficient surface scratch resistance due to oxygen inhibition during light coating can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of coatings, more specifically, to a method for preparing a high-wear-resistant UV matte coating and a method for preparing the UV matte coating. Background technique [0002] In the field of consumer electronics, protective and packaging films are needed for process protection and product protection packaging before leaving the factory. Most of the commonly used materials are soft materials such as OPP and BOPP. In the decoration industry, PVC film, as a decorative film material with the characteristics of rich patterns, clear, good layering, high simulation and convenient construction, has developed rapidly in furniture decoration, decoration industry, car interior decoration and other applications and has become a new type of surface decoration. The materials sector dominates. In the field of sealing, graphite gaskets have good corrosion resistance, high and low temperature resistance, compression resili...
