Problems solved by technology

[0003] At present, the application of recoating paint on the market is mainly to polish the position where the product needs to be recoated, and then spray a layer of recoating paint (that is, treatment agent) to solve the problem. If the treatment is uneven, it will cause recoating adhesion and appearance. Unbalanced, it is difficult to meet the rework requirements of recoated products

Embodiment 1

[0017] Embodiment 1: recoat bright light UV paint, be prepared by the composition of following mass percent: aliphatic polyurethane resin 35%, epoxy acrylic resin 20%, monomer 18%, cellulose resin 12%, fluid Leveling agent 0.5%, initiator 4.5% and solvent 10%.

Embodiment 2

[0018] Embodiment 2: recoat bright light UV paint, be prepared by the composition of following mass percent: aliphatic polyurethane resin 38%, epoxy acrylic resin 14%, monomer 15%, cellulose resin 15%, fluid Leveling agent 0.5%, initiator 5.5% and solvent 12%.

Embodiment 3

[0019] Embodiment 3: recoat bright light UV paint, be prepared by the composition of following mass percent: aliphatic polyurethane resin 30%, epoxy acrylic resin 15%, monomer 18%, cellulose resin 20%, fluid Leveling agent 0.3%, initiator 6.7% and solvent 10%.

[0020] In any of the above-mentioned embodiments, the aliphatic polyurethane resin is a four-functionality aliphatic polyurethane resin, which provides the recoatability of the entire paint film; the epoxy acrylic resin is a two-functionality epoxy polyurethane resin, which provides fullness for the entire paint film and leveling; the monomer is dipentaerythritol hexaacrylate, which provides high physical and chemical properties for the entire paint film; the leveling agent is fluorine-modified polyacrylate, which has rapid leveling properties and also provides the paint film with Recoatability; the initiator is 1-hydroxycyclohexyl benzophenone, which provides rapid curing performance for the entire paint film; the sol...

Abstract

The invention discloses a recoat light UV (ultraviolet) coating which is prepared from the following components in percentage by mass: 30-50% of aliphatic polyurethane resins, 10-30% of epoxy acrylic resins, 15-20% of monomers, 10-30% of cellulose ester resins, 0.2-0.5% of a flatting agent, 4-8% of an initiator and 10-20% of a solvent. The coating disclosed by the invention can be directly recoated on a product, the appearance and adhesive force of the product are uniform, and the defective percentage caused by non-uniform recoating after grinding is reduced.

Description

technical field [0001] The invention relates to a UV paint, in particular to a recoatable bright UV paint. Background technique [0002] 3C electronic products are a general term for three types of electronic products: Computer, Communication and Consumer Electronics. In recent years, my country's 3C industry has made great progress. As far as consumer electronics products are concerned, their market size has grown from 800 billion yuan in 2008 to over one trillion yuan in 2014. The computer and communication equipment markets are also developing rapidly. Computers, communications and consumer electronics have high requirements for anti-corrosion and appearance decoration, which are closely related to the coatings used. The quality of the surface coating process has become one of the important indicators to determine the product grade. [0003] At present, the application of recoating paint on the market is mainly to polish the position where the product needs to be recoa...
