Problems solved by technology

Although these two Chinese patents have solved the problem that the U.S. patent US561162 produces a large amount of organic waste liquid and cyanide-containing wastewater and the production cost is too high in the process of producing water-insoluble heterocyclic haloamine polymer sterilization and disinfection resin materials, and the preparation of the U.S. patent US7687072B2 The problem that the surface of the water-insoluble heterocyclic halamine polymer sterilization and disinfection resin material is relatively poor in hydrophilicity, but the content and stability of the oxidized halogen of the water-insoluble heterocyclic halamine polymer sterilization and disinfection resin material prepared by it need to be determined. Further improve

Abstract

The invention relates to a macroporous crosslinked antibacterial macromolecular resin containing a halamine functional group, as well as preparation and application thereof. According to the preparation, acrylic acid, acrylate, acrylamide and the like serving as monomers of polymerization, an amide crosslinking agent serving as a crosslinking agent of polymerization, and benzene, methylbenzene, xylene and the like serving as a pore-foaming agent perform a polymerization reaction under the action of an initiator to generate a macroporous crosslinked copolymer resin containing a halamine functional group; and the macroporous crosslinked antibacterial macromolecular resin containing a halamine functional group is generated by means of a halogenating reaction of the halamine functional group. Compared with the prior art, the antibacterial macromolecular resin has a quick, effective and broad-spectrum antibacterial effect, can be widely applied to sterilization and disinfection treatment of various water bodies and air and control of harmful unpleasant gases, and can be subjected to certain mixing treatment with other materials to prepare various sanitary antibacterial products, such as antibacterial mattress protectors, antibacterial carpets, antibacterial diapers and the like.

Description

technical field [0001] The invention relates to a high-molecular polymer bactericide, in particular to a macroporous cross-linked bactericidal high-molecular resin containing a haloamine functional group, as well as its preparation and application. Background technique [0002] The application of effective antibacterial and disinfection materials and technologies is an important means to block the spread and prevalence of harmful microorganisms. Due to the disadvantages of high toxicity and easy pollution caused by water-soluble fungicides, the development of water-insoluble polymer fungicides, especially water-insoluble resin fungicides has attracted more and more people's interest. US Patent No. 4,349,646 discloses a method for preparing water-insoluble polyquaternium bactericidal resin by reacting chloromethylated polystyrene resin or polychloromethacrylate resin with tertiary amine or di-tertiary diamine. US4826924 discloses a polystyrene resin or polystyrene-divinylben...
