Problems solved by technology

In the past, the formula of some cleaning agents used ether and alcohol. After cleaning, a grease film after ether volatilization would be left, which would have a certain impact on the anti-reflection coating. For example, refer to Shu Weiguo, Chemical Cleaning, Beijing Aeronautical Technology Research Institute, 1993
[0003] After use, the lens will also be stained with some dust, sweat, juice, hair spray, cosmetics, etc., which requires a special lens cleaner to clean. If you use a seemingly soft paper towel to wipe, the paper contains The wood pulp is easier to scratch the coating on the lens

Abstract

The invention discloses a resin lens cleaning agent. According to 100 parts by weight, the resin lens cleaning agent comprises the following active ingredients: 15-25 parts of N,N-dimethyl formamide (DMF) solution, 0.2-0.3 part of ethylenediamine, 4-6 parts of potassium dihydrogen phosphate-potassium dihydrogen phosphate, 13-20 parts of sodium lauroamphoacetate, 8-12 parts of ethylene glycol solution and the balance of deionized water solution. The preparation method comprises the following steps: placing all the components into a dosing tank, and fully stirring to obtain the resin lens cleaning agent. According to the resin lens cleaning agent, the decontamination rate of the formed lens is not less than 99%, and the resin lens cleaning agent has no damage to the lens; the resin lens cleaning agent is low in wetting degree on the surface of the lens, and the resin lens cleaning agent and the residual contamination on the lens can be separated from the lens from the surface of the lens only by slightly throwing after the lens is cleaned with the resin lens cleaning agent, and the resin lens cleaning agent is not volatilized, decomposed and combusted, and is safe to use, and the resin lens cleaning agent is an environment-friendly alkaline water-soluble liquid cleaning agent without halogenated hydrocarbon.

Description

technical field [0001] The invention relates to a cleaning agent, in particular to a resin lens cleaning agent and a preparation method thereof. Background technique [0002] Non-contact lenses are very precise optical components, especially epoxy resin lenses, crystal lenses, etc., the surface of which has been treated with anti-reflection coating, especially after the lens is molded. The coating is very damaged, which will affect the optical performance and imaging quality of the lens, and will cause further damage to the user's vision. Do not use other chemicals to clean the lens. This is because other types of chemical cleaning agents are not specially designed for cleaning the lens. Such cleaning agents may damage the resin lens and the coating, and may Residual resin shavings and fingerprints after molding are not cleaned. In the past, some cleaning agents were formulated using ether and alcohol. After cleaning, a grease film after ether volatilization would be left,...
