Abstract

The invention relates to chitosan hydrogel, a preparation method of the chitosan hydrogel, an antiviral spray and antiviral liquid gloves. Reaction raw materials of the chitosan hydrogel comprise thefollowing components in parts by mass of 90 to 108 parts of partially acrylated chitosan aqueous solution, 42 to 60 parts of polyvinylpyrrolidone aqueous solution, 40 to 60 parts of gelatin aqueous solution, 0.4 to 0.6 part of photoinitiator 1173, 1.8 to 2.3 parts of fumed silica, 4.8 to 5.2 parts of mutton fat ester, 4.8 to 5.5 parts of coconut diethanolamide and 1.9 to 2.1 parts of fatty alcoholpolyoxyethylene ether sodium sulfate; and the partially acrylated chitosan aqueous solution comprises the following components in parts by mass of 420-580 parts of a chitosan acetic acid aqueous solution and 42-60 parts of an ethanol solution of acrylate glycidyl ether. The chitosan hydrogel can be used for preparing liquid gloves and antiviral spray with remarkable antibacterial and antiviral effects.

Description

technical field [0001] The invention relates to the technical field of biomedical materials, in particular to a chitosan hydrogel and a preparation method, an antiviral spray, and an antiviral liquid glove. Background technique [0002] The outbreak of the new crown pneumonia epidemic in 2020 has greatly endangered the health of the people, affected the social order and stability of the country, and caused a series of serious impacts on the economy, culture, exchanges, and diplomacy. Respiratory infectious diseases similar to COVID-19 cause such great harm because of their strong infectivity, mainly because the virus is transmitted through droplets in the air and enters the human body through the respiratory tract. It is fast, invasive, and difficult to detect in the early stage Carriers and exposed persons are neglected to protect and are infected on a large scale. [0003] It is extremely important to cut off the source of infection and do a good job of self-protection. F...
