High abrasion-resistant UV (ultraviolet) white primer for electrostatic spraying

Abstract

The invention relates to a high abrasion-resistant UV (ultraviolet) white primer for electrostatic spraying. The high abrasion-resistant UV white primer is prepared from the following raw materials in parts by weight: 40 to 70 parts of epoxy acrylic resin, 15 to 35 parts of hydroxy acrylic resin, 10 to 20 parts of thermoplastic acrylic resin, 15 to 30 parts of tripropylene glycol diacrylate, 5 to 25 parts of modified graphene, 2 to 6 parts of nanometer silicon dioxide, 1 to 5 parts of nanometer titanium dioxide, 1 to 5 parts of heavy calcium carbonate, 5 to 15 parts of montmorillonite, 10 to 20 parts of white pigment, 2 to 5 parts of zinc stearate, 2 to 6 parts of carboxymethyl cellulose sodium, 1 to 5 parts of polyamide wax, 0.5 to 2 parts of flatting agent, 0.1 to 0.5 part of defoaming agent, 2 to 6 parts of photoinitiator, and 5 to 15 parts of organic solvent. The high abrasion-resistant UV white primer for electrostatic spraying has the advantage that at the premise of ensuring the good electrostatic spraying effect, the anti-sagging property of the primer and the abrasion-resistant property of the primer film are greatly improved.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a high wear-resistant UV white primer for electrostatic spraying. Background technique [0002] Ultraviolet light-curable coating (UV paint) is automatically rolled and shower-coated on the surface of the furniture board by machinery and equipment. Under the irradiation of ultraviolet light (wavelength 320-390nm), the initiator is decomposed, free radicals are generated, and the resin reaction is triggered. Curing into film, its advantages include: stable color, long-lasting and always new, effectively solving the problem of fading and color difference of the door panel; the mirror surface of the door panel is better, and the paint film is full without orange peel; UV paint is currently the most environmentally friendly baking paint in the world One of the door panels; the hardness of the door panel is twice that of other painted door panels, scratch-resistant, acid and alkali r...

AI Technical Summary

Problems solved by technology

However, most of the UV electrostatic spraying primers are transparent primers at present. After adding pigments, the viscosity is high, and the anti-sagging performance is deteriorated. At the same time, the wear resistance of the formed paint film cannot be guaranteed.
