Description

A kind of ABS/PET composite antibacterial material and preparation method

Technical field

The invention discloses a kind of ABS/PET composite antibacterial material and preparation method thereof, belong to engineering materials manufacturing technology field.

Background technology

Present stage, engineering materials goods occupy very consequence in people's daily life and industrial and agricultural production.Along with engineering materials goods are in the extensive popularization and application in daily field, people contact more frequently and use as plastics, thus more and more higher to the requirement of these goods.And nature also exists various microorganism, in daily life, microorganism and the mankind have close relationship, and people are not contacting with microorganism all the time.But part microorganism as the so-called pathogenic bacterias such as bacterium, fungi and virus but serious harm the health of the mankind.According to data statistics, the whole world causes dead number to exceed 2,200 ten thousand because of bacteriological infection every year, accounts for 35% of death toll sum.Therefore take precautions against in daily life and avoid the propagation of toxic bacteria and infect just seeming particularly important.At present, the production of anti-biotic material has become an emerging industry, and countries in the world are all carried out on a large scale to the research of anti-biotic material.And the sterilization of the antibacterial concept in material and the control germ in microorganism has very large difference, its not requirement can kill the microorganism be pernicious to people at once, but be emphatically the breeding that can suppress unwanted bacteria in the life-time service process of material, keep the health of environment.

Anti-biotic material refers to and adds antiseptic-germicide in the material, is that material itself has antibacterial effect, can suppresses or kill the bacterium of material surface within a certain period of time, can play the effect of protection to environment and the frequent human consumer contacting this material.The exploitation of anti-biotic material and be applied as consumers in general and provide a kind of guarantee, for improving living environment, protection fitness-for-all, reduces pathophoresis tool and is of great significance.But at present, highly effective anti-biotic material is actually rare, be therefore badly in need of developing a kind of broad-spectrum efficacious anti-microbial material.

Summary of the invention

In order to overcome above the deficiencies in the prior art, the invention provides a kind of ABS/PET composite antibacterial material, improve the antibacterial effect of material by adding different antiseptic-germicides, ABS/PET composite property is superior simultaneously, can be widely used in the every field of daily productive life.
