UV transfer glue formula and manufacturing process

Abstract

The invention discloses an UV transfer glue formula and a manufacturing process. The UV transfer glue formula is prepared from the following components in parts by weight: 30-38 parts of prepolymer, 56-65 parts of an acrylate monomer, 1-4 parts of a photoinitiator and 0.2-1 part of an auxiliary agent, wherein the acrylate monomer is a complex of single functional acrylate and double functional acrylate; the single functional acrylate is isobornyl acrylate and the double functional acrylate is 1,6-hexadiol diacrylate; the weight ratio of the single functional acrylate to the double functional acrylate is (3-4): (1-1.5). The manufacturing process comprises the following steps: first, preparing a complex of isobornyl acrylate and 1,6-hexadiol diacrylate; then preparing a prepolymer; and thenmixing the prepolymer, the acrylate monomer, the photoinitiator and the auxiliary agent to obtain the UV transfer glue. The UV transfer glue has the advantages of being high in curing speed, increasedin film forming crosslinking density, good diluting property, excellent glue flatting property, relatively small in volatility, relatively slight in smell, low in shrinkage rate and extremely good inadhesive force and has hardness, flexibility and scratch resistance.

Description

technical field [0001] The invention relates to the technology in the field of UV transfer glue, in particular to a UV transfer glue formula and manufacturing process. Background technique [0002] UV transfer adhesive is a light-curing single-component molding dispensing glue, which is mainly formed on the surface of other polyester films such as PC, PET and TPU through molds, and can also be placed on the surface of the film alone. It is mainly used to make high-end mobile phone buttons and buttons. CD drawing pattern, etc.; during the transfer operation, inject UV glue onto the transfer mold through the dispensing head, and then place the substrate to be printed on the transfer mold; The mold is pressed together to make the UV glue between the base material and the transfer mold uniform; then the light-fixed shape is carried out by the light-curing unit to complete the entire UV transfer process.

Problems solved by technology

[0003] There are various existing UV transfer adhesives, most of which are prepared by mixing prepolymers, polymerized monomers, photoinitiators, etc. However, in actual use, UV transfer adhesives have many deficiencies, which limit The quality of the transfer product, such as: pungent smell, low bond strength, large shrinkage deformation, poor transfer surface smoothness, poor transparency, etc.; these deficiencies, on the one hand, depend on the formula of the UV transfer adhesive, On the other hand, it depends on the production process of UV transfer glue; therefore, in the present invention, starting from the formula of UV transfer glue and its production process, the shortcomings of traditional UV transfer glue are effectively improved.
