Abstract

The invention discloses a glasses repairing gel and a preparation method thereof. The glasses repairing gel comprises the following substances: acetylated hemicellulose, polyvinyl alcohol, boric acid, glycerol, aloe vera gel and a coupling agent. The glasses repairing gel is prepared by mixing natural extracts such as acetylated hemicellulose, polyvinyl alcohol, boric acid, glycerol and aloe vera gel with vegetable oil, has a good lens repairing effect, is natural in smell, free of adverse health influence, safe to use, capable of being iteratively used for many times, can be used for repairing scratched and worn glasses and other optical lenses, and has a good industrial prospect.

Description

technical field [0001] The invention discloses a gel, in particular to a glasses repair gel and a preparation method thereof, belonging to the field of polymer chemistry. Background technique [0002] At present, there are more than 600 million myopic people in my country. Unfortunately, myopia is currently incurable. In addition to wearing glasses, the only way you can save your vision is through myopia surgery. The myopia rate of teenagers exceeds 50%. Myopia is becoming more and more "popular" in China. In China, factors such as high academic pressure, lack of outdoor activities, excessive use of electronic products, and low awareness of overall prevention and control are considered by ophthalmologists to be the main causes of high incidence of myopia. factor. [0003] China has now developed into a major consumer and producer of glasses in the world. In addition to practical functions, glasses are also endowed with decorative functions, which further gave birth to ne...
