Abstract

The invention discloses an ultraviolet curing transfer adhesive. The adhesive comprises the following components in percentage by weight: 45 to 67 percent of oligomer, 30 to 52 percent of activated monomer, 2 to 4 percent of free radical photoinitiator, and 1 to 3 percent of auxiliary, wherein the oligomer is one or more of epoxy acrylic ester, urethane acrylate and polyester acrylate; and the activated monomer is one of acrylic ester of a mono-functional group, a bifunctional group or a polyfunctional group. The ultraviolet curing transfer adhesive can form patterns with various shapes, can be cured at the room temperature in 20 seconds, can greatly reduce energy consumption, improve yield, is more suitable for continuous production, can improve the production efficiency, and has stable and reliable performance and high environmental protection property in the high-temperature high-dampness environment.

Description

technical field [0001] The invention relates to an acrylic ester transfer printing adhesive, in particular to an ultraviolet light curing transfer printing adhesive used for forming keys and casings. Background technique [0002] With the explosive growth of mobile phones, notebook computers and office electronic products in the late 1990s and their rapid popularization around the world, buttons and casing products have formed a large-scale industry, especially mobile phones. Laptop keys, shells, etc. From the early days to the beginning of this century, the keys of mobile phones were mainly made of pure silicone rubber, PC, ABS, nylon and other plastic products, and the shells of notebooks were mainly made of mixed injection molding of PC and ABS; in recent years, the keys and shells of mobile phones and notebooks were mainly made of polyester film ( The combination of PC, PET, TPU) and UV curing transfer adhesive surface molding. Plastic is a thermoplastic material with ...
