Abstract

The invention discloses an optical plastic protection coating and a preparation method thereof. The optical plastic protection coating comprises the following raw materials in parts by weight: 2 parts of ethyl orthosilicate, 5-6.5 parts of phenyl trimethoxy silane, 1.5-2 parts of a coupling agent, 3-4 parts of distilled water, 0.02-0.03 part of a curing agent and 0.02-0.04 part of a catalyst. The preparation method comprises the following steps: adding the raw materials into a container, stirring, standing at the room temperature for 24 hours to obtain colorless transparent liquid, coating an optical plastic plate with the liquid, and drying at 80 DEG C to form a layer of coating on the optical plastic plate, wherein the coating is the optical plastic protection coating. The optical plastic protection coating has the characteristics of high transparency, high hardness and the like, can be widely used in the field of optical plastic protection, and also can be used in the fields of coatings, printing ink 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 ...
