Abstract

The invention discloses an optical plastic protective coating and a preparation method thereof. The optical plastic protective coating is calculated in parts by weight, that is, 2 parts of ethyl orthosilicate, 5-6.5 parts of phenyltrimethoxysilane, 1.5-2 parts of coupling agent, 3-4 parts of distilled water, 0.02 ~0.03 parts of curing agent and 0.02~0.04 parts of catalyst were added to the container in turn, stirred and left at room temperature for 24 hours, the obtained colorless and transparent liquid was coated on the optical plastic plate and dried at 80°C, and then placed on the optical plastic plate The resulting layer of coating is the optical plastic protective coating. The optical plastic protective coating has the characteristics of high light transmittance, high hardness, etc., and can be widely used in the field of optical plastic protection, and can also be used in the fields of coatings, inks, and the like.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to an optical plastic protective coating and a preparation method thereof. Background technique [0002] Compared with optical glass, optical plastic has many advantages such as light specific gravity, strong impact resistance, low cost, good light transmission, safety and reliability, etc., so it is widely used for making spectacle lenses, windshields on airplanes and cars, and cameras various lenses. However, optical plastics also have problems such as easy scratches and poor heat resistance. In order to overcome the above shortcomings, Zhang Chongzhao prepared a wear-resistant optical plastic protective optical plastic protective coating with a mixture of tetraalkoxysilane, trialkoxysilane, and dialkoxysilane through a catalytic reaction. The wear-resistant optical plastic protective coating has Certain hardness and wear resistance, but the siloxanes used ...
