Description

A kind of antibiotic polymer material
Technical field
The present invention relates to a kind of polymkeric substance, particularly a kind of antibiotic polymer material with permanent anti-microbial property.
Background technology
Antibiotic polymer material generally can obtain by following two kinds of methods:
1, directly add organic molecule antiseptic-germicide or inorganic antiseptic in polymer materials, this is the simplest a kind of method.What use morely now is with inorganic antiseptic, and the zeolitic material as metal ion (silver ions, cupric ion, zine ion etc.) directly adds in the polymeric matrix, mixes the back with polymeric matrix, directly prepares corresponding devices.In the textile industry field, handle fabric with the organic antibacterial agent of quaternary ammonium salt very early, so that fabric has anti-microbial property.But no matter be to add inorganic antiseptic or add the organic molecule antiseptic-germicide, their common shortcomings are that antiseptic-germicide can break away from polymeric matrix and runs off, and make goods lose anti-microbial property on the one hand, on the other hand, also can produce harm to environment and human body.
2, make material have anti-microbial property by the method for polymeric matrix being carried out chemical modification.Such as methods such as the block reaction of using graft reaction, surface chemical modification, polymkeric substance and monomeric direct copolymerization reactions, the functional group that will have anti-microbial activity, formal bond with chemical bond is incorporated on the substrate molecule chain of polymkeric substance, makes material have anti-microbial property.This is a kind of more advanced method, and it has solved antibiotic polymer material and has caused its anti-microbial property to reduce owing to the prolongation of time and to environment and the unsafe problem of human body.
China patent CN00125768.4 has described a kind of preparation method of polypropylene dedicated material, is reacted on the polypropylene matrix by the oligopolymer that will have anti-microbial activity, obtains having the polypropylene dedicated material of permanent anti-microbial property.It is the preparation of the anti-biotic material of base-material that but this patent is only applicable to the polypropylene.
China patent CN02111048.4 has further described the preparation of other polyolefine antibacterial plastic concentrates, comprise polyolefine materials such as polyethylene, polyvinyl chloride, polystyrene, the use that the method for chemical bonding is prepared antibiotic polymer material is further widened, and makes its Application Areas wider.
U.S. Pat 5408022 has been described the method with copolymerization, and preparation has the polymer materials of permanent anti-microbial property.The antibacterial monomer that uses is the quaternary amines monomer that has two keys, and the number of two keys can form crosslinked structure for one or more.Other used monomers mainly are acrylate or methyl acrylic ester.But employed antibacterial monomer has expensive shortcoming.
U.S. Pat 6326417B1 provides a kind of polymerisable antimicrobial compound.The antiseptic-germicide that uses is Whitfield's ointment, salicylate class, sulfanilamide (SN), or their composition.Monomer mainly is esters of acrylic acid and methyl acrylic ester.The polymkeric substance that the inventor introduces acquisition has permanent germ resistance.
