Problems solved by technology

[0003] At present, there are two types of waterproofing chemicals sold in the market: ordinary waterproofing chemicals and superhard waterproofing chemicals. The ordinary waterproofing chemicals produced in Korea account for about 85% of the market share, and the sales price is 4.2 yuan / grain. The domestic ordinary waterproofing chemicals account for the market share. 15%, the sales price is 3.5 yuan / grain, the superhard waterproof medicine is also mainly produced by South Korea, accounting for about 90% of the market share, Japan's production accounts for 10%, the sales price is 60 yuan / grain, of which ordinary waterproof medicine The surface hardness of the formed coating is low. Although the glasses are worn very carefully, they are still full of scars. Although the surface hardness of the lens evaporated with super-hard water repellent has improved, it is still not ideal. After spot checks, the surface hardness has not yet reached National standard expressly stating that the haze value of hardened lenses is less than 0.8

Abstract

The invention discloses a method for making super hard water-proof medicine. The method comprises steps of: 1) selecting perfluoroalkylsulfonyl propyl trlethyloxy sllane as main material, adding 160ml~240ml isopropyl alcohol, and 18~22 grams water in per 100 grams perfluoroalkylsulfonyl propyl trlethyloxy sllane, and stirring uniformly; 2) stirring the solution and adding 8~12 grams acid solution, heating to 55~65 centigrade and sealed reacting 6~8 hours; 3) filtering and air-drying the reacted solution and getting light yellow amorphism crystal which molecular weight is 20000~40000 and boiling point is 300~400 centigrade; 4) crashing the crystal into 20 categories and mixing with perfluoroalkylsulfonyl quaternary amnonium iodides in proportion of 7:2~7:4 to obtain super hard water-proof medicine powder; 5)making the medicine powder into particles.

Description

technical field [0001] The invention relates to a preparation method of an optical coating material for forming an anti-wear and waterproof layer on the surface of spectacle lenses and the like. Background technique [0002] In the prior art, after the hardening treatment, the surface firmness of the optical lens has reached 6-7H, which has a certain anti-friction effect, and can be sold as a finished product. It is generally called a hardened lens, and a hardened lens Although the strength of the surface is good, the transmittance of visible light is only 88% to 92%. The anti-reflection film is evaporated on the surface of the hardened lens, so that the transmittance of visible light can reach more than 98%, and the performance has been greatly improved. It is called a hardened and coated lens. The vapor-deposited anti-reflection film is carried out in a vacuum special equipment with high technical content. The vacuum coating materials used mainly include: silicon dioxide, ...
