Embodiment 2

[0037] Other steps are the same as above, except that the molar ratio of guanidine itaconate hydrochloride and styrene in step 2 is 1:1.

Embodiment 3

[0039] Other steps are the same as above, except that the molar ratio of guanidine itaconate hydrochloride and styrene in step 2 is 1:5.

Embodiment 5

[0041] Other steps are the same as described above, except that the molar ratio of guanidine itaconate hydrochloride and styrene in step 2 is 1:3.

[0042] Change the ratio of styrene and guanidine itaconate hydrochloride according to the different uses of the antibacterial fiber (if the strength is high, the proportion of styrene is appropriately increased; if the antibacterial effect is better, the proportion of guanidine itaconate hydrochloride is higher).

Thefiber synthesis method is simple and convenient, and has strong sterilization and bacteriostasis capabilities; the price is cheap; the disinfectant has broad sterilization spectrum, quick effect, longlasting sterilization capability, safety, innocuity and environmental protection; the disinfectant has a strong killing effect on brucella abortus, bacillus coli, staphylococcus aureus, blastomyces albicans and the like, has good stability, is valid for up to two years, and has the advantages of easy smearing, rapid penetration, fast volatilization, no coloring, easy cleaning and the like; and the disinfectant can be used for skin and wound disinfection, hand disinfection, air disinfection, gynecology and urology disinfection, drinking water disinfection and the like, is a new, ideal and convenient disinfectant.

Description

technical field [0001] The invention relates to the field of disinfection products, in particular to a preparation method of itaconate guanidinostyrene copolymerization disinfection fiber. Background technique [0002] Itaconic acid was once considered one of the top 12 biochemicals produced by biotechnological means. Its potential applications in the field of green chemistry are numerous. At present, itaconic acid and its chemical derivatives are considered as niche chemicals of low industrial relevance, with active chemical properties, which can undergo self-polymerization and can also be polymerized with bactericidal monomers to form macromolecules The compound is then spun to form antimicrobial fibers. The antibacterial agent in the antibacterial fiber can prevent harmful microorganisms from adhering to the fiber itself. When it is attached to the fiber, it is inhibited and then killed, thereby protecting the user. People are inevitably exposed to various viruses, bac...
