Description
Technical field
The present invention relates to a kind of LDPE plastics, more particularly to a kind of Anti-bacterial LDPE plastic and preparation method thereof.
Background technique
Currently, plastic products occupy highly important status in daily life and industrial and agricultural production.But with
The change of health of people idea, gradually recognize that surface of plastic products can largely be bred and all kinds of cure the disease to human health
Bacterium.People be effectively prevent and kill off and kill the bacterium that frosting is grown nonparasitically upon another plant, generally use in the plastic add antibacterial agent be made it is anti-
Bacterium plastics, make plastics itself have antibiotic property, can will stain bacterium on plastics within a certain period of time and kill or inhibit, and normal
The chemically and physically method of rule is compared, long using antibiotic plastic sterilization timeliness, not only economical but also conveniently.It the exploitation of antibiotic plastic and answers
One of green screen has been set up with for protection human health, for improving environment for human survival, has reduced disease, the protection whole people are strong
Health has a very important significance.Due to antibiotic plastic fundamentally can reduce or avoid person to person, people and object, object with
The cross-infection of bacterium between object, the plastic products with antibacterial functions are generally valued by people and welcome.
Plastics are broadly divided into organic and inorganic antiseptic with antibacterial agent, and inorganic antibacterial agent is mostly metal ion class antibacterial
Agent is made of carrier and antimicrobial component.This antibacterial agent is adhered to metal ion using the methods of ion exchange, absorption, precipitating
On the carriers such as zeolite, titanium dioxide, ceramics, apatite.Antimicrobial component is silver ion, zinc ion, copper ion etc., wherein due to
Silver-ion antibiotic power is most strong, so using more.But its chemical property is living, is easily changed into the silver oxide of brown or urges through ultraviolet light
Change the elemental silver for being reduced to black, constrains it in the application of more multiregion.Inorganic antiseptic can be directly appended in resin,
Antibacterial plastic concentrate can first be made again.This antibacterial agent heat resisting temperature can be used in PE, LDPE, PVC, PS, ABS up to 270 DEG C or more
In the plastics such as polyester.Inorganic antiseptic have many advantages, such as it is long-acting, do not generate drug resistance, occupy in the development of plastics antibacterial agent
Very big advantage.The sterilization of inorganic antiseptic and antifungal mechanism are that heavy metal ion is easily in conjunction with protein in inorganic antiseptic, institute
With when the microorganism for being grown in frosting touches the antimicrobial component in plastics, metal ion strong adsorption bacterium.Due to
The combination of enzyme in metal ion and bacterial cell destroys the space structure and activity of enzyme, makes the metabolism of microorganism can not
It can be carried out, to play sterilization and antibacterial effect.Organic antibacterial agent includes natural and the big series of synthesis two.Natural antibacterial agent master
If being mentioned in crab and shrimp made of refining refinement in animals and plants, such as the extract of behenyl, Meng Zongzhu, peppermint, lemonlike citrus leaf etc.
The polyhexamethylene guanide etc. of refining.Organic antibacterial agent sterilizes, and speed is fast, and what is had can effectively kill suppression mould, but it removes the safety used
It is poor outer, the problems such as there is also poor heat resistance, facile hydrolysis, short service lifes.
Since different antibacterial agents is to the Antibacterial mechanism of pathogen of the same race and the difference of validity and antibacterial of the same race
Agent is also different for the antibacterial action mechanism and inhibition range of different pathogens, therefore, to develop not only long-acting but also wide spectrum, height
The antibacterial agent of effect, it is particularly significant to the research of Antibacterial Mechanism.
