Technical field
The present invention relates to plastic material technical field, a kind of novel antibacterial plastics are disclosed.
Background technology
The new demand of antibacterial epoch：In recent years, emerge in an endless stream and the generation of hazardous events is propagated because of bacterium infection, the mankind are for anti-
The importance of bacterium deeper into understanding, therefore for 3C electronic products, people's livelihood articles for use, for example underskirt trousers, socks, infant into
Articles for use between people's paper diaper, women sanitary articles, such as sanitary cotton pad, sanitation of bath-room, such as cleaning agent, clean hand breast, hand lotion, sterilization are killed
Bacterium solution, it is house protective articles, such as mouth mask, air-conditioning systems cleaning filter screen, medical supplies, such as bandage, wound patch, artificial
Skin, antibiotic and sterilizing saline solution etc., the health requirements of house building materials etc., from environmentally friendly, the safety of raw material, it is to avoid traditional preservatives
Contact use, further lifting is to requirement to antibacterial.Plus people's life increased quality and requirement, with antibacterial functions
Product has formed an important link.
Because plastics have the advantages that light weight, not corrosion, good insulating, industrial goods and daily necessities apparatus are widely applied to
On.Existing antibiotic plastic because product cost is high, quality is unstable cannot meet people the need for, particularly plastics food and drink
Apparatus, because self character cannot be using the conventional antimicrobial means of high temperature sterilization, it is impossible to effectively go out viral and thin except surface attachment
Bacterium, the health of harm people, therefore people are good to bactericidal effect, low cost is suitable to wide variety of antibiotic plastic, there is urgent
Demand.
Research shows, when being contacted with bacterium using positively charged zinc ion, is produced because the cell membrane/wall of bacterium is pulled open
Raw broken hole, makes bacterium to carry out cell membrane/wall and is pulled open and produce broken hole, bacterium is carried out the generation of cell membrane/wall
And influence breeding.When zinc ion is entered in bacterial body by negative electrical charge sound-absorbing, with internal thiol base（-SH）, the functional group such as hydroxy
With reference to making bacterium because of protein denaturization, it is impossible to be normally carried out other reactions of catalysis and influence metabolic function, until bacterial death is simultaneously
It is wholly absent only.With high activity, the addition of about 0.05% nanometer zinc particles, you can cause that human infection is common five kinds
Pathogen, such as multiple drug resistance staphylococcus aureus（MRSA）, streptococcus pneumonia, Candida albicans, Pseudomonas aeruginosa, black aspergillus
Deng the bactericidal effect for producing 99.99%, also there is manifest function to superbacteria, H1N1, veteran bacterium etc..
The content of the invention
The present invention provides a kind of novel antibacterial plastics, safe and reliable, and bactericidal effect is strong, and the antibiotic effect retention time is long.
In order to reach above technique effect, technical scheme is as follows：
A kind of novel antibacterial plastics, its constituent includes following components with percentage by weight：

Coupling agent 0-2%；
Stabilizer 0-2%.
Preferably, constituent includes following components with percentage by weight：
Nano-antibacterial particle 3%；
Plastics major ingredient 94%；
Plasticizer 2.5%；
Coupling agent 1%；
Stabilizer 0.5%.
The nano-antibacterial particle is nano-sized metal particles, used as preferably nanometer zinc particles.
The plastics major ingredient is polyvinyl chloride.
The plasticizer is epoxies or citric acid ester plasticizer.
The coupling agent is siloxanes.
The stabilizer is phthalate or epoxy type stabilizers.
Further, the nano-antibacterial particle is prepared via a method which：
Step one, solvent is added using nano metal predecessor, is configured to precursor liquid；
Step 2, the precursor liquid that step one is obtained is inserted in ultrasonic response groove, carries out ultrasonic irradiation, to produce gas
Erosion effect；
Step 3, polymer electrolyte interfacial agent, reducing agent and stabilization agent are added in reaction hot-zone；
Step 4, after reaction terminates, collects abovementioned steps and peels off the metallic for producing；
Step 5, by step 5 gained metallic, imports vacuum high-temperature baking oven and is recrystallized, and clipped wire is received in acquisition
Son.
The present invention has the advantages that compared with prior art：
The invention provides a kind of novel antibacterial plastics, good anti-bacterial effect, effect duration is long, by SGS JIS Z
2801 antibacterial test specifications, can be by cause human infection common five kinds of pathogens, such as multiple drug resistance Staphylococcus aureus
Bacterium（MRSA）, streptococcus pneumonia, Candida albicans, Pseudomonas aeruginosa, black aspergillus etc. produce 99.99% killing effect, to super thin
Bacterium, H1N1, veteran bacterium etc. also have manifest function；Tested by SGS ASTM F1980, possess more than 5 years antibiotic effects.
Antibiotic plastic of the invention has automatic sterilizing mechanism, nontoxic to human body nonirritant, can be used in preparing table ware and
Toy for children etc. is to antibacterial product of the requirement with high request, while product of the invention also has the advantage of low production cost,
With high market popularization value and competitiveness.
