Antifogging resin optical lens and preparation method thereof

Abstract

The invention belongs to the field of material chemistry, and mainly provides an antifogging resin optical lens and a preparation method thereof. The antifogging agent is prepared from a pre-sol (synthesized from acrylic acids, acrylates, acrylamide, an initiator and a silane crosslinking agent), a heteropolyacid hardening agent, and an alcohol or ketone solvent. The preparation method comprises the following steps: synthesizing the pre-sol, preparing an antifogging agent, pretreating a resin optical lens, coating the antifogging agent on the lens, and curing. The antifogging resin lens prepared by the method has the advantages of favorable antifogging performance, excellent light transmittance, excellent frictional resistance and longer service life.

Description

technical field [0001] The invention belongs to the field of material chemistry and mainly provides an antifogging agent for resin lenses and a preparation method for antifogging resin optical lenses. Background technique [0002] At present, resin optical lenses are usually prepared by copolymerization of allyl diglycol, carbonate, and methyl methacrylate. This type of product has good optical and mechanical properties, and has gradually replaced inorganic glass and become the mainstream of optical materials in the market. However, no matter what kind of transparent material, when there is a certain temperature difference between the two sides, when the vapor pressure of the surrounding environment is higher than the saturated vapor pressure of the moisture on the surface of the substrate, the water vapor will accumulate on the surface of the transparent substrate and form small water droplets. The form of precipitation forms water mist, and the tiny water droplets will ca...

Problems solved by technology

[0008] However, in these existing anti-fog materials, the performance we need is not enough.

That is to say, these anti-fog materials may reduce the light transmittance of the transparent substrate; or scratches will appear after several times of use without friction resistance, which also affects the light transmittance of the transparent substrate; The adhesion between materials is not very good, and it is easy to swell and fall off when exposed to water, which makes the service life of the anti-fogging agent too short
