Abstract

The invention relates to a chitosan hydrogel, a preparation method, an antiviral spray, and an antiviral liquid glove. The reaction raw materials of the chitosan hydrogel include: in parts by mass, a partially acrylated chitosan aqueous solution of 90-108 parts, 42-60 parts of polyvinylpyrrolidone aqueous solution, 40-60 parts of gelatin aqueous solution, 0.4-0.6 parts of photoinitiator 1173, 1.8-2.3 parts of fumed silica, 4.8-5.2 parts of lanolin, 4.8-5.5 parts of coconut oil Diethanolamide, 1.9-2.1 parts of fatty alcohol polyoxyethylene ether sodium sulfate; the partially acrylated chitosan aqueous solution includes: in parts by mass, 420-580 parts of chitosan acetic acid aqueous solution, acrylate glycidyl ether 42 to 60 parts of ethanol solution. The chitosan hydrogel can prepare liquid gloves and antiviral sprays with significant 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 people's health, affected the social order and stability of the country, and caused a series of serious impacts on economy, culture, exchanges, and diplomacy. Respiratory infectious diseases similar to new coronary pneumonia cause such great harm because of their strong infectiousness. The main reason is that the virus is transmitted through droplets in the air and enters the human body through the respiratory tract. It is fast and invasive, and it is difficult to detect early Carriers and exposed persons are infected in a large area due to neglect of protection. [0003] It is extremely important to cut off the source of infection and do a good job in self-protec...
