Abstract

The invention relates to a hardening, anti-ultraviolet and anti-glare multifunctional paint for a polarizer which is designed for solving the technical problem of poor effect of existing like products used in polarized lenses. The paint is prepared by the following steps of: performing a cohydrolysis reaction of a plurality of alkoxysilanes and deionized water under the action of acid catalyst and at a certain temperature to obtain a mixture; adding organosilicon modified acrylic acid or epoxy resin into the mixture to remove a solvent while performing condensation polymerization; adding a component solvent which takes propylene glycol methyl ether as the main component, proper amount of curing agent and polyether modified siloxanes to prepare the organosilicon hardening matrix component; and adding nano-titanium oxide solution which serves as an ultraviolet absorbent into the organosilicon hardening matrix component and adding indium oxide semiconductor nano-particles which have a infrared absorption function, fluorine-contained acrylic acid copolymer, the catalyst and the like into the mixture to obtain the paint. The paint is coated on a polarizer substrate material, has multiple functions such as hardening, ultraviolet protection, glare elimination, water vapor resistance, infrared absorption and the like, and is suitable for sunglasses and safety goggles.

Description

technical field [0001] The invention relates to a polarizer for an optical element or an instrument, and relates to a hardened anti-ultraviolet and anti-glare multifunctional coating for the polarizer. Background technique [0002] As we all know, a polarizer is an optical film composed of multi-layer polymer materials and has the function of generating polarized light. It has important uses in the glasses industry, optical equipment, and display industries. For example, the application number 200910105443.6 published in the Chinese patent literature, the publication date was July 29, 2009, and the invention patent application titled "a reflective anti-glare polarizer, its special coating and its preparation method" is characterized in that it is directly in the The reflective anti-glare coating is coated on the triacetate cellulose (TAC) optical film. The reflective anti-glare coating has anti-glare, hardening, anti-fouling and anti-static functions, which reduces the tradi...
