Complex liquid for preventing fog on spectacle glasses

Abstract

The invention belongs to the field of light chemical materials and specially, relates to a complex liquid for preventing fog on spectacle glasses. The complex liquid for preventing fog on spectacle glasses can protect spectacle glasses. The complex liquid for preventing fog on spectacle glasses is prepared from linear alkyl benzene sulphonic acid, sodium alcohol ether sulphate, alkanolamide, fatty alcohol-polyoxyethylene ether, disodium ethylene diamine tetraacetate, a sodium chloride saturated solution, glycol stearate, alkyl ether sulfate, potassium sorbate, lime, paraffin, eleaostearic acid, talcum powder and deionized water according to a certain volume ratio. Through a sodium hydroxide saturated solution, a pH value of the complex liquid for preventing fog on spectacle glasses is adjusted to 7. The complex liquid for preventing fog on spectacle glasses is an odorless, colorless and transparent liquid having certain viscosity. A use method of the complex liquid for preventing fog on spectacle glasses comprises that the complex liquid is coated on spectacle glasses and after the complex liquid is dried in air, the spectacle glasses with the complex liquid are gently wiped by glasses cloth. The complex liquid for preventing fog on spectacle glasses can keep clearness of spectacle glasses for a long time, avoids a lot of troubles for people, and solves the problem of the unnecessary interference caused by fog suddenly produced on spectacle glasses.

Description

technical field [0001] The invention belongs to the field of light chemical materials, and in particular relates to a composite liquid capable of protecting spectacle lenses and preventing fogging of spectacle lenses. Specifically, the eyeglass lens is fogged due to the drastic change in temperature difference, which affects the vision of the eyeglass lens. Background technique [0002] In winter or when entering and exiting an air-conditioned room, the eyeglass lenses are prone to fogging under the action of heat. Whether it's walking into a room or moving a car, fogging up the glass can cause blurred vision. At present, automobiles mainly adopt the method of spraying and releasing heat to solve the problem. But for spectacle lenses, it is very inconvenient to wipe them with cloth, and there is no suitable soft cloth in most occasions, and when wiping the glasses, the lenses are prone to scratches. Therefore, it is a technology with great research value whether it is con...

AI Technical Summary

Problems solved by technology

At present, there is a lack of understanding in the aspect of preventing spectacle lenses from fogging. Basically, it is solved by using simple soft cloth, napkins or even wiping with hands, and no one has worked hard to solve this problem.

There is a kind of anti-fog cream for bulletin board glass windows, which is more expensive, and firstly it must be applied on the glass, and it must be wiped evenly with a soft cloth, but it still has a certain impact on the glass field of view and the operation procedure is cumbersome; Not very suitable; there is no simple and effective technology to prevent eyeglass lens fogging
