Embodiment 1

[0028] (a) UV rays are completely isolated, and yellow light is used for lighting;

[0029] (b) According to the proportion, add 3% photoinitiator BASF184 and 1% TPO into 5% ethyl acetate to dissolve, stir evenly, and the stirring speed is 500rpm;

[0030] (c) Keep stirring, add 10% LR8987, 20% 3000B, 40% UVR-68, 10% Tego.SK, 0.1% EFKA3299 (leveling agent), 0.4% EFKA4010 (dispersion) in order agent), 1% polyethylene wax, and continue to stir for 15 minutes;

[0031] (d) Moisten and disperse 2.5% pearlescent powder with the remaining 5% ethyl acetate, and soak for 10 minutes;

[0032] (e) continuously stirring, adding the soaked pearl powder obtained in step (d) to the mixture obtained in step (c);

[0033] (f) Add 1% nano-titanium white paste and 1% phthalocyanine blue paste, adjust the color, and stir evenly. The resulting product is a high wear-resistant recoatable UV matte paint, which is recorded as A1.

Embodiment 2

[0035] (a) UV rays are completely isolated, and yellow light is used for lighting;

Abstract

The invention provides a high abrasion-resistance ultraviolet (UV) matte coating capable of recoating. The coating is characterized by being prepared from, by mass, 30%-50% of prepolymer, 20%-40% of matte prepolymer, 1%-10% of thermoplastic acrylic resin, 1%-8% of photoinitiator, 1%-15% of flatting wax, 1%-10% of pearl powder, 0-10% of transparent color paste, 0.1-1% of flatting agent, 0-1% of dispersant and 10%-20% of solvent. The high abrasion-resistance UV matte coating capable of recoating is excellent in construction performance, excellent in hardness and adhesive force and excellent in abrasive resistance by matching and adjusting the types and contents of different polymers in the formula.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a high wear-resistant recoatable UV matte coating and a preparation method and application thereof. Background technique [0002] UV-cured matte paint is obtained by adding matte powder on the basis of UV-cured paint. This paint is a low-gloss paint. The appearance of the paint film obtained by curing it is soft and not strong, so it is also called Soft light, currently widely used as a top coat for laptops, wood, leather and metal, etc. [0003] At present, matte powders with smaller particle diameters are basically added to UV-cured matte coatings. The reason is that the particle diameter is too large to easily cause rough surface of the paint film after photocuring, spots appear, the surface condition deteriorates, and the hand feel Poor, and easy to cause a drop in paint film adhesion. However, the small particle diameter will also make it difficult to disperse the matte p...
