Abstract

The invention relates to an application of a polyethyleneimine grafted guanidine polymer, which comprises the following steps: forming a guanidine polymer by using polyhexamethylene guanidine hydrochloride and branched polyethyleneimine or ethylenediamine terminated polyethyleneimine, and grafting the polyethyleneimine grafted guanidine polymer by using the guanidine polymer as a grafting agent, other sterilization and disinfection compounds, disinfectants or water treatment filter membranes are grafted and modified, so that the bacteriostasis and disinfection effects of other sterilization and disinfection compounds, disinfectants or filter membranes are enhanced or endowed, and the sterilization and disinfection effect duration is prolonged. The application range of the guanidine disinfectant is widened, and the sterilization and disinfection efficiency and action time of the guanidine disinfectant are greatly improved from the aspects of effective binding property of guanidyl on a target compound / product, adsorbability of the guanidyl on the surface of a microbial cell membrane, distribution density of the guanidyl, the guanidyl overcoming steric hindrance and being exposed outside molecules and the like.

Description

technical field

[0001] The invention relates to the technical field of disinfectant products, in particular to the use of guanidine polymers grafted with polyethyleneimine. Background technique

[0002] In recent years, guanidine-based polymers (PHGH) have been widely used as disinfectants in daily life, and they have efficient bactericidal effects. However, in practical applications, due to its relatively few functional groups, its adhesion and adsorption are not high. When it is used for product grafting, as the product is used for a long time, the disinfection effect of the product will be greatly increased. decline, thus limiting the application of guanidine disinfectants in different production fields and products. SUMMARY OF THE INVENTION

[0003] (1) Technical problems to be solved

[0004] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides the use of guanidine polymers grafted with polyethyleneimine, whic...
