Abstract
The invention discloses a quaternary phosphonium ammonium salt sterilizing resin and a preparation method and application thereof, and belongs to the technical field of resins. According to the invention, the acrylic resin skeleton and the amination process containing hydroxyl are adopted to covalently connect the sterilizing quaternary phosphonium/quaternary ammonium group with the resin, and the synergistic sterilizing capability of the quaternary phosphonium salt and the quaternary ammonium active group is utilized, so that the resin has the advantages of stable sterilizing performance, long service life, regeneration and reuse and the like.
Description
Technical Field
The invention belongs to the technical field of resins, and particularly relates to a quaternary phosphonium ammonium salt sterilizing resin and a preparation method and application thereof.
Background
The main current sterilization modes mainly comprise chlorine sterilization, chlorine dioxide sterilization, ozone sterilization, ultraviolet sterilization and the like. In the disinfection processes, disinfectant and organic matters, bromide, iodide and the like in water can generate disinfection byproducts such as trihalomethane, haloacetic acid, haloacetonitrile, nitrosamine and the like, and the disinfectant shows dominant genetic toxicity and carcinogenicity, and threatens the safety of drinking water. Meanwhile, stress pressure generated by long-term coexistence of the disinfectant and the drinking water can lead to appearance of resistant bacteria and enrichment of resistant genes, such as pseudomonas aeruginosa, bacillus subtilis and the like, which are difficult to kill in a conventional disinfection mode, so that great health risks exist.
It is found by searching that the existing additive type antibacterial resin can be used for mixing the antibacterial agent with the resin or immersing and fixing the antibacterial agent in the resin to form the resin which can be used for disinfection and sterilization and can be used for ion exchange. For example, the Chinese patent application of publication No. CN1280771A discloses a long-acting broad-spectrum sterilization ion exchange resin, and the sterilization agent is selectively loaded on the ion exchange resin, so that the sterilization can be performed in the process of ion exchange treatment of water body; for example, the publication No. CN101891865a discloses an antibacterial polyethylene resin and a preparation method thereof, wherein a small molecular organic antibacterial agent is mixed with an auxiliary monomer, then an initiator is added and fully and uniformly mixed to obtain a mixture, and the polyethylene PE resin and the mixture are subjected to thermomechanical mixing, reaction, extrusion and other treatments to obtain the antibacterial polyethylene resin. However, the existing additive antibacterial resin has the problems of easy migration and loss of antibacterial agent, short antibacterial time and the like.
