Problems solved by technology

The use of colorless / blue uv adhesive can simplify the assembly process, overcome airtightness, and reduce costs, but the light-colored adhesive cannot achieve the ideal shading effect, and the stray light caused by transmission and reflection seriously affects the imaging quality of the image lens. Unable to meet high-pixel imaging requirements
In addition, the current colorless / blue uv glue adopts a free radical-induced curing mechanism, which is difficult to overcome the problem of black deep-layer curing. The present invention adopts a cationic curing mechanism to develop a radiation-curable black light-shielding material to solve the above technical problems

Abstract

The invention discloses a radiation-curable black light-shielding adhesive composition. The weight percentage of each raw material is: 30%-70% of mercaptan modified hyperbranched vinyl ether resin, 10%-30% of aliphatic epoxy resin %, reactive diluent 10%-50%, photoinitiator 0.1%-4%, filler 2%-15%, black paste 1%-10%, additive 0.5%-5%. The present invention "A 2 The +Bx" synthesis method is simple and efficient, no by-products are generated in the click reaction, and tedious and time-consuming purification and separation processes are not required, which greatly reduces the cost. The low viscosity of the hyperbranched vinyl ether resin material provides convenience for the formulation design of the shading adhesive. Conducive to dispensing production operations.

Description

technical field [0001] The invention relates to the field of adhesives, in particular to a radiation-curable black light-shielding adhesive composition. Background technique [0002] In recent years, with the continuous development of science and technology, electronic equipment has been developing towards intelligence. For example, mobile phones and tablet computers have flooded the lives of modern people, and imaging equipment loaded on portable electronic products has also flourished. develop. While people pursue the miniaturization of digital cameras, video cameras and mobile phones with shooting functions, they also put forward higher requirements for the image quality of the objects they shoot, that is, they hope that the images of the objects they shoot will be clearer. Therefore, in addition to improving the quality of the optical design of the image lens, the precision of manufacturing and assembly also needs to be improved. [0003] A general lens module includes...
