Abstract

The invention discloses a material for optical element processing and a preparation method thereof. The present invention includes α-cyanoacrylate, acetyl citrate triester, tris (2-n-butoxyethyl) phosphate, trimethylolpropane tris (3-mercapto propionate), cellulose, gas phase dioxide Silicone, Tannic Acid, Phthalic Anhydride. The present invention adopts a solvent with a branched chain structure and complexing ability, the solvent ratio is high, and at the same time reduces the curing speed and curing stress of α-cyanoacrylate, and the obtained optical element processing material has low viscosity, small PV value, and appropriate bonding strength It is suitable for the bonding of optical components.

Description

technical field [0001] The invention belongs to the technical field of optical precision processing, and in particular relates to a material for optical element processing and a preparation method thereof. Background technique [0002] Optical glass components are widely used in transistors, integrated circuits, printed circuit boards and other semiconductor devices and projectors due to their unique physical and chemical properties, such as high hardness, good optical transparency, various refractive indices, and good homogeneity. Instruments, telescopes, optical microscopes and other optical instruments. Due to the performance requirements of optical components, it is often necessary to strictly polish the frosted glass surface. During the polishing process, the glass to be processed needs to be fixed on a stainless steel mold. In particular, some high-end optical components require high-precision mirror surface shape of optical glass, and its PV value is less than or equ...
