Problems solved by technology

The deficiencies of most glass UV transfer adhesives currently on the market are mainly manifested in: 1. Poor adhesion to glass; 2. After the UV adhesive is transferred to the glass surface, it is not resistant to boiling (boiling water); 3. Hardness relatively low
Document CN106281198 discloses a preparation method of glass UV transfer glue, including aliphatic urethane acrylate, acrylate reactive diluent, photoinitiator, acrylate auxiliary agent and silane coupling agent, the glass UV obtained by this method Although the hardness of the transfer glue is relatively high, it can only withstand boiling water for 10 minutes. After using the auxiliary process of baking at 150°C for 30 minutes, its resistance to boiling water can only reach about 30 minutes.

Abstract

The invention relates to a glass UV transfer adhesive with high hardness and strong boiling resistance and strong adhesion and its application. The UV transfer adhesive, in parts by weight, includes the following components: 1-5 parts of fluorine-containing urethane acrylate oligomers, 30-50 parts of urethane acrylate oligomers, and 1-10 parts of fluorine-containing acrylate monomers parts, 40-60 parts of acrylate monomer, 3-5 parts of photoinitiator, and 1-5 parts of auxiliary. The UV transfer adhesive provided by the invention has high hardness, high adhesion to glass, and excellent resistance to boiling water, and is especially suitable for UV transfer of glass in GDM process.

Description

technical field [0001] The invention relates to a high-hardness boiling-resistant glass UV transfer glue and its application. Background technique [0002] UV glue, also known as UV-curable glue, generally includes oligomers, diluting monomers, photoinitiators and other additives. The principle of UV glue curing is to make the photoinitiator generate active free radicals or cations through the irradiation of UV light in a specific band, thereby initiating the polymerization of monomers, so that the adhesive can be transformed from liquid to solid in a very short time. [0003] Glass UV transfer glue is a kind of UV glue. It is a light-curing single-component molding dispensing glue, which is mainly molded on the surface of the glass plate through a mold. Glass UV transfer glue is mainly used in the shell decoration of consumer electronics products, including mobile phone cameras, mobile phone back covers, earphones, refrigerators, car decorations and other glass shell surfa...
