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 (Ultraviolet) transfer printing adhesive with high hardness, water-boiling resistance and strong adhesive force and application thereof. The UV transfer printing adhesive comprises the following components in parts by weight: 1-5 parts of a fluorine-containing polyurethane acrylate oligomer, 30-50 parts of a polyurethane acrylate oligomer, 1-10 parts of a fluorine-containing acrylate monomer, 40-60 parts of an acrylate monomer, 3-5 parts of a photoinitiator and 1-5 parts of an additive. The UV transfer printing adhesive provided by the invention has high hardness, high adhesive force to glass and excellent water-boiling resistance and is particularly suitable for glass UV transfer printing in a GDM (Glass Direct Molding) 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...
