Description

Macromolecule quaternary salt anti-biotic material and preparation method thereof
One, technical field:
The present invention relates to a kind of high-molecular anti-bacteria material and preparation method thereof, particularly relate to a kind of macromolecule quaternary salt anti-biotic material And preparation method thereof.
Two, background technology:
Along with material and goods such as developing rapidly of high-molecular organic material industry, plastics, fiber, rubber, coating and adhesive Increasingly extensive is employed.These materials and goods, such as plastic packing product, if not having antibacterial functions, antibacterial, mycete etc. Can corrode products to be packaged makes it rotten or damage.Antibacterial, mycete etc. are to the pollution of product surface and grow, and to using and can connect The people touching it produce cross infection, and health is constituted certain threat.Anti-biotic material is to some antibacterials, mycete, fungus etc. The extremely sensitive chemical substance of microorganism, not only itself has antibacterial functions, adds it to plastics, fiber, rubber, coating With the material such as adhesive with in goods, it is possible to give its antibacterial functions, not only keep material and goods self not by antibacterial, mycete Deng destruction, packaged article can also be protected to never degenerate or sustain damage as packing articles；Can also avoid or reduce because of The cross-contaminations such as antibacterial between person to person, people and the thing, thing and the thing that use these goods and occur, mycete, are beneficial to people Health.
Produce now and the high-molecular anti-bacteria material of application, be by mean of high-molecular organic material more and be prone to the advantage of processing and forming, With little molecule inorganic antiseptic, organic antibacterial agent are blended by simple physical or increase-volume physical blending prepares.Be mainly used in plastics, The goods such as fiber, rubber, coating and adhesive.Though the anti-biotic material so prepared and goods have antibacterial functions, but have one Outstanding problem: due to the limited compatibility of antibacterial Yu matrix, antibacterial easily migrates loss, causes keeping antibacterial functions Long-lasting.Also can pollute packaged article as packaging material and goods, easily human body etc. be damaged again.It is linked with anti- The organic high molecular compound of bacterium functional group both separately formed can be processed into the goods with antibacterial functions, overcomes again little molecule Antibacterial physical blending gives the shortcoming of antibacterial functions in macromolecular material, the most also has more antibacterial than little molecule antibacterial Performance.Therefore, synthesis and the application of high-molecular anti-bacteria material is just becoming the current focus researched and developed.
