Long-acting antibacterial permanent antifogging liquid medicine, lens, and preparation process and application thereof

Abstract

The invention relates to a long-acting antibacterial permanent antifogging liquid medicine, a lens and a preparation process and application thereof. The long-acting antibacterial permanent antifogging liquid medicine comprises the following raw materials in parts by weight: 1 part of antifogging liquid medicine VPP, 0.5-0.6 part of an antibacterial agent LB3, 1-1.2 parts of diacetone alcohol and 1-1.5 parts of propylene glycol monomethyl ether. The antibacterial test on the product according to the Chinese national standard GB / T 31402-2015 Plastic Surface Antibacterial Performance Test Method shows that the antibacterial value is greater than 2, the antibacterial activity rate is greater than 99%, and the long-acting antibacterial effect is achieved. The anti-fog effect of the lens can reach the permanent KN index meeting the European standard, so that the optical performance of the glasses is better, and the visual effect is better.

Description

technical field [0001] The invention relates to the technical field of eyeglasses, in particular to a long-acting antibacterial and permanent anti-fog solution, a lens, and the preparation process and application of the lens, including goggles, protective masks and other lens products. Background technique [0002] There are many kinds of microorganisms harmful to human body in natural life, including: [0003] 1. Bacteria: Bacteria are ubiquitous, invisible to the naked eye, reproduce at an alarming rate, and produce an unpleasant smell in a short period of time. Products that people often touch can lead to cross-infection of bacteria. Can cause tetanus, typhoid, pneumonia, tuberculosis, etc. [0004] 2. Mold: Mold grows slowly and is visible to the naked eye, causing permanent damage to polymer materials, accompanied by unsightly mildew spots. It can lead to fungal inflammation such as onychomycosis, beriberi, skin diseases, and fungal inflammation. [0005] 3. Yeast: ...

Problems solved by technology

[0004] 2. Mold: Mold grows slowly and is visible to the naked eye, causing permanent damage to polymer materials, accompanied by unsightly mildew spots

[0005] 3. Yeast: Yeast reproduces quickly, produces sticky matter, and releases peculiar smell at the same time, which affects hygiene and health

[0008] Existing lenses do not have antibacterial effect, which is not conducive to long-term healthy wearing, and will also affect the visual effect due to the growth of bacteria; or they cannot have both antibacterial and anti-fog functions. The use of occasions, such as goggles, protective masks, etc.; or poor antibacterial effect, short service life
