Embodiment Construction

[0007] The first step is to mix 3-(2,3-epoxypropoxy)propyltrimethoxysilane with tetrabutyl titanate, tetrabutyl titanate / 3-(2,3-epoxypropoxy) Propyltrimethoxysilane=10% (weight ratio), diluted with tetrahydrofuran, tetrahydrofuran: 3-(2,3-epoxypropoxy)propyltrimethoxysilane=3:1 (weight ratio); add catalyst formic acid HCOOH and water H 2 O, HCOOH:Si=3 (molar ratio), H 2 O: Si=3 (molar ratio); Synthesis temperature is 30 DEG C; During the continuation of the reaction, when the average molecular weight reaches 1438 by gel chromatography, stop the reaction. At this time, the viscous sol solution of 3-(2,3-epoxypropoxy)propyl silsesquioxane containing titanium dioxide was synthesized, hereinafter referred to as titanium-containing silsesquioxane, and the titanium-containing silsesquioxane Dilute with tetrahydrofuran, tetrahydrofuran:titanium-containing silsesquioxane = 4 (weight ratio), then seal and store for future use.

[0008] In the second step, when the resin lens is coat...

Abstract

The invention discloses a titanium-containing organic-inorganic hybridized nano abrasion-scratch resisting protective film. The film relates to an abrasion-scratch resisting protective material whichis mainly applied to resin eyeglasses. The film is invented aiming at the defects that the prior resin eyeglass is soft and easy to be abraded and scratched so as to influence the wearing effect and the like. The hybridized protective film is implemented through a two-step raw material matching and synthesizing method which comprises the following steps: a first step, hydrolyzing and condensing 3-(2, 3-epoxypropoxy) propyltrimethoxysilane and tetrabutyl titanate by using a sol-gel method to synthesize stable titanium-containing silsesquioxane sol solution; and a second step, adding hexamethylene diamine cross linker and tetrahydrofuran diluent solvent into the titanium-containing silsesquioxane, and heating and curing the resin eyeglass by adopting a dip-coating method to form the netliketitanium-containing organic-inorganic hybridized nano structural protective film. The protective film has the characteristics of scientific formulation, simple synthetic method, good abrasion resistance and scratch resistance, and easy popularization.

Description

technical field [0001] The invention relates to a titanium-containing organic-inorganic hybrid nanometer anti-wear and scratch protective film mainly used for resin lenses, which belongs to the field of chemical industry. Background technique [0002] With the development of science and technology, resin lenses have been accepted by more and more people because of their lightness, thinness, unbreakability and simple processing technology, and are gradually replacing traditional glass lenses. But in use, people also found that resin lenses are relatively soft, easy to wear and scratch, and affect the wearing effect. As the demand for resin lenses increases, it is imperative to develop high-performance, high-quality anti-wear and anti-scratch protective films for resin lenses with soft materials. Contents of the invention [0003] The purpose of the present invention is to provide people with a kind of high-tech anti-wear and scratch protection with good performance, simple...
