Problems solved by technology
The domestic existing coatings for electrostatic spraying are generally primers, the obtained paint film is rough and uneven, and the decorative effect is poor, so it is not suitable for use as a topcoat
There is a lack of topcoats that can be applied to electrostatic spraying in China
The topcoat for electrostatic spraying in foreign countries generally adjusts the conductivity of the coating by adding conductive additives, which is expensive, has poor after-sales service, and has high requirements for spraying equipment, so it cannot be well applied to domestic electrostatic spraying equipment, and there are few applications.
[0004] UV coating is also a highly efficient and environmentally friendly coating, and there is currently no report on UV topcoats that can be applied to electrostatic spraying

Abstract
The invention discloses UV surface paint applied to electrostatic coating. The UV surface paint contains the following components in part by mass: 24 to 32 parts of aminoacrylic resin, 8 to 12 parts of urethane acrylate, 25 to 31 parts of 1,6-hexanedioldiacrylate, 7 to 11 parts of trimethylolpropane triacrylate, 8 to 11 parts of tripropylene glycol diacrylate, 2.5 to 4 parts of photo-initiator, 0.1 to 0.5 part of flatting agent, 2.5 to 4 parts of butanone and 5.5 to 6.5 parts of acetic ether. The UV surface paint has high solid content and low environmental pollution, is applied to electrostatic coating and has very good atomizing effect; and an obtained workpiece surface film has uniform thickness, is smooth and has no orange peel phenomenon. Meanwhile, a paint film has high fullness, good luster and good hardness. The UV surface paint is particularly suitable for various carpentry workpieces which need multi-face coating such as violins, guitars, seats, photo frames and the like. The painting rate is over 90 percent, the loss is low, the work efficiency is equivalent to that of manual coating with 40 persons, and the UV surface paint can meet the requirement of efficient production.
Description
technical field [0001] The invention relates to a paint for electrostatic spraying, in particular to a UV finish paint applied to electrostatic spraying. Background technique [0002] Compared with traditional spraying, electrostatic spraying has higher production capacity, can be mechanized, automated, and continuous production, the utilization rate of paint is as high as 80-90%, the paint film is uniform, the adhesion is good, the pollution is small, and the working conditions are good. It is an efficient and environmentally friendly construction process. [0003] Electrostatic spraying has high requirements for coatings, and the spraying effects obtained by different coatings vary greatly. The existing coatings for electrostatic spraying in China are generally primers. The obtained paint film is rough and uneven, and the decorative effect is poor, so it is not suitable for use as a topcoat. There is a lack of topcoats that can be applied to electrostatic spraying in Chi...
