Background
The adhesive is a substance that bonds adherends together by adhesion. The material can be organic or inorganic, natural or synthetic, and can be solidified to have enough strength. The optical adhesive is a special adhesive, and is characterized by colorless or light-colored transparent, light transmittance of over 90 percent in a specified light wave band, good bonding strength, capability of being cured at room temperature or intermediate temperature, small curing shrinkage and the like.
The optical adhesive is widely applied in the electronic industry, and the types of OCA adhesive films, LOCA and the like are common in the market at present. In the aspects of gap filling property and irregular surface filling, the OCA adhesive tape can only be used for filling gaps of not less than 0.1 mu m generally, and for the adhesion of rough surfaces with curved surfaces, complex surfaces, higher printing ink thickness or uneven surfaces and the like, the OCA adhesive tape can not completely meet the use requirements, and sometimes the problems of bubble residue, size insensitivity and the like exist. In addition, the quality of the cemented binding surface is often unstable due to the complex processes of rolling, vacuum bonding, defoaming and the like adopted in the production process of the OCA tape, and the defects of low light transmittance, large refractive index, easy yellowing and the like exist. The liquid optical adhesive (LOCA) has good bonding strength and appropriate soft ductility, and is suitable for bonding between glass and glass, between glass and a flexible film, between glass and other electronic devices, and the like, and is gradually replacing the traditional OCA tape gluing method. However, the existing liquid optical cement also has some disadvantages: if the low temperature resistance is low, the light transmission is poor, and the requirements of products cannot be met.
