Problems solved by technology

Ordinary vacuum spraying UV primer contains some organic solvents, the resistance value is low, the electrostatic coating effect is poor, and it needs a certain drying time, and the sanding property is poor
The ordinary UV resin contained in it has a large surface tension, and it is difficult to have good wettability and leveling, which will cause some places to be too thick after recoating, while some places are not coated with paint

Abstract

The invention provides an environment-friendly light-curing electrostatic spraying primer, comprising the following components in percentage by weight: 10-20% of 2-Propenoic acid,1,1'-[(1-methyl-1,2-ethanediyl)bis[oxy(methyl-2,1-ethanediyl)]] ester, 1-5% of trimethylolpropane triacrylate, 5-8% of a photo-initiator, 15-20% of epoxy acrylate, 20-25% of polyester acrylic resin, 5-8% of polyurethane acrylic resin, 0.2-0.5% of a flatting agent, 0.2-0.5% of an anti-settling agent, 5-12% of flour, 5-10% of 1,6-hexanediol diacrylate, 5-8% of 2-ethylhexyl acrylate and 0-0.2% of a defoaming agent. The light-curing electrostatic spraying primer adopts a UV monomer with low viscosity and strong dilution capacity to replace an original solvent, contains no VOC (Volatile Organic Compounds), can be recycled and belongs to green and environment-friendly paints; UV resin with low viscosity and good wettability is used as main resin so that the content of solid paint is high; and the light-curing electrostatic spraying primer can be directly applied to electrostatic spraying without being diluted by the organic solvent and has the advantages of good atomization effect, good package to devices, excellent adherence and good rubbing property.

Description

technical field [0001] The invention relates to the technical field of spraying primers, in particular to an environmentally friendly light-curing electrostatic spraying primer. Background technique [0002] Primer is the paint that is directly applied to the surface of the construction object. It is the basic material on the surface of the workpiece and the medium layer between the intermediate coating or the overcoat and the surface of the object. The primer is the first layer of the paint system, which is used to improve the adhesion of the topcoat, increase the fullness of the topcoat, provide alkali resistance, provide anti-corrosion functions, etc. At the same time, it can ensure the uniform absorption of the topcoat and make the paint system play its best good effect. Ordinary vacuum spraying UV primer contains some organic solvents, the resistance value is low, the electrostatic coating effect is poor, and it needs a certain drying time, and the sanding property is ...
