Description
Technical field
The present invention relates to a kind of plastics, specifically a kind of antibiotic plastic and preparation method thereof.
Background technology
Household electrical appliances are the indispensable instruments of each family, and the plastics major part for household electrical appliances is thermoplastic, accounts for 90%, its
Middle major part is general-purpose plastics, mainly has several classes as follows.1st, general-purpose plastics：Polypropylene (PP), polystyrene (PS), polrvinyl chloride
(PVC) etc..2nd, engineering plastics：Acrylonitrile/butadiene/styrene terpolymer (ABS), polyamide (PA), Merlon
(PC), polyformaldehyde (POM), polyphenylene oxide (PPO), polyethylene terephthalate (PET), polybutylene terephthalate (PBT)
(PBT), polyurethane (PUR) etc..3rd, thermosetting plastics：Phenolic resin, amino resins, epoxy resin etc..Because plastics have matter
Gently, high, the excellent electrical insulation capability of intensity, excellent chemical stability, good printing opacity and barrier propterty and damping, noise reduction
Performance-jump becomes the indispensable material of household appliances manufacturing.Plastics consumption in household electrical appliances, has accounted for the 40% of weight ratio at present.With
Household appliance appearance more and more diversified, art up, requirements at the higher level are proposed to special-effect plastics.In the feelings ensureing properties of product
Under condition, by using new material, new design, new technology.With people to healthy attention further, to the antibacterial of household electrical appliances and sterilization
Functional plastics proposes higher, more normalized requirement, it is reported that antibiotic plastic is used for refrigerator, laundry by increasing enterprise
Machine, water dispenser, electric cooker, air cleaner etc. are to reduce microorganism pollution and pathogenic bacteria cross infection.In addition, in household electric appliances,
Product plastic become household electric appliances important development direction it-, it is the fastest that plastics have become field of household appliances application amount growth rate
Material, in recent years every average annual growth rate reached 29.5% about.
In daily life, quite-part noxious bacteria is that exist on the surface of plastic and breed, and by contact
Lead to various diseases.With the continuous enhancing to health and environmental consciousness for the people, to contacting frequently household electric in daily life
Device plastic components propose the demand of " antibacterial, sterilization ".
The core ingredient of antibiotic plastic is antibacterial.Organic antibacterial is due in safety, thermostability, Durability of antimicrobial effect
And the aspect Shortcomings such as broad-spectrum antibacterial property and limit its application；Natural antimicrobial agent toxicity is low, using safety, but exists
Poor heat resistance, the shortcomings of range of application is narrow, Durability of antimicrobial effect is poor；Inorganic antiseptic then avoids disadvantages mentioned above and so that it is being moulded
Application in material field is extremely paid attention to.Inorganic antiseptic is broadly divided into metal ion system and is two big class by the emperor himself.It is anti-that the former adopts
Bacterium active ingredient mainly has the metal ions such as silver, copper, zinc.The anti-microbial property of silver ion is the strongest, but its chemical property is active, easily turns
Turn to the silver oxide of brown or the elemental silver of black, should not be widely used in white domestic appliances.The antibacterial strength of zinc is only silver
1/1000；Copper ion has color, and it is attractive in appearance that a large amount of uses can affect product.The instant effect although metal ion sterilizes, a large amount of uses
High cost, and the release of heavy metal ion will have a negative impact to environmental and human health impacts.The latter has photocatalytic activity
Height, Durability of antimicrobial effect are strong, inexpensive nontoxic and stronger self-cleaning function, but such antibacterial is only in ultraviolet light and natural light
Competence exertion antibacterial action under conditions of exciting, in many, unglazed irradiation applications are restricted all the year round.Occur in that on market
Multiple composite bactericidal agent, but antibacterial effect is still not good；And the preparation method of existing Domestic plastic is complicated, increase
Production cost.Therefore, market needs the antibiotic plastic of a kind of good anti-bacterial effect, simple production process, low production cost.
