Abstract

The invention discloses a material for processing an optical element and a preparation method thereof. The environment-friendly water-based paint is prepared from alpha-cyanoacrylate, acetyl citric acid triester, phosphoric acid tri (2-n-butoxyethyl) ester, trimethylolpropane tri (3-mercaptopropionate), cellulose, fumed silica, tannic acid and phthalic anhydride. The solvent with a branched chain structure and complexing capacity is adopted, the solvent proportion is high, meanwhile, the [alpha]-cyanoacrylate curing speed and curing stress are reduced, and the obtained material for optical element processing has the characteristics of low viscosity, small PV value and proper bonding strength and is suitable for bonding of optical element processing.

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...
