AI Technical Summary

Problems solved by technology

However, the adhesive uses a high-viscosity epoxy resin, and the internal stress generated after curing will still cause some bonded rigid thin materials to deform or even crack, and the bonded glass is difficult to fall off in hot water, so it is not suitable for optical glass Cutting and bonding

Abstract

The invention discloses an optical glass processing material. The raw materials and proportions are as follows: 20-50 parts by weight of polyglycol glycidyl ether; 20-30 parts by weight of polyethylene glycol acrylate; 10 parts by weight of hydroxy acrylate ~20 parts by weight; 16~20 parts by weight of morpholine acrylic acid; 1~3 parts by weight of free radical initiator; 2~4 parts by weight of cationic initiator; 0.5~1.0 parts by weight of adhesion promoter Parts; polymerization inhibitor 0.5-2 parts by weight. The present invention abandons the high-molecular-weight resin used in traditional UV adhesives, and adopts low-molecular-weight UV water-soluble monomers and specific adhesion promoters. The obtained optical glass processing materials have low viscosity, small shrinkage stress, and appropriate bonding strength. It is easy to degumming in hot water, suitable for bonding of optical glass cutting and processing.

Description

technical field [0001] The invention belongs to the technical field of optical glass processing materials, in particular to a preparation method of an adhesive for optical glass processing. Background technique [0002] Optical glass is widely used in transistors, integrated circuits, printed circuit boards and other semiconductor devices and projectors due to its unique physical and chemical properties, such as high hardness, good optical transparency, various refractive indices, and good homogeneity. , telescopes, optical microscopes and other optical instruments. Due to product requirements, optical glass often needs to be cut into specific sizes for use. The scribing process, especially some high-end optical components, has high requirements for the cutting of optical glass, such as glass chipping or excessive micro-cracks. , will seriously affect the quality of the product, and even cause the product to be scrapped. [0003] Authorized invention patent by Li Cuiying, ...
