Abstract
The invention discloses a kind of high tenacity antibiotic plastic and its preparation technology, the high tenacity antibiotic plastic includes polyphenylene oxide, polystyrene, antimicrobial powder, styrene-based copolymers.High tenacity antibiotic plastic security of the present invention is good, has good antibacterial ability, while has excellent mechanical performance and processing characteristics concurrently, can be widely used for household electrical appliances, automobile, electronic applications.
Description
Technical field
The present invention relates to a kind of plastics, and in particular to a kind of high tenacity antibiotic plastic and its preparation technology.
Background technology
Plastics suffer from extensive purposes in industrial circle and people's daily life, with high-performance polymer material
Continually develop, its application field is also constantly expanded, and has penetrated into each department of national economy at present.With family daily necessity
And the household electrical appliance become increasingly popular enter huge numbers of families, many common items：Such as phone, elevator button, computor-keyboard, refrigerator
Inner carriage kitchen utensils and various electric switches etc. touch position, can all turn into the propagating source of pollution sources and bacterium, so as to
Influence the health of user.The optimal path for solving this problem is to confer to the ability of material antibiotic and sterilizing itself.
Conventional antiseptic is broadly divided into inorganic antiseptic, organic antibacterial agent and natural antibacterial agent at present.Organic antibacterial agent energy
Effectively suppress the growth and breeding of harmful bacteria, it is quick, but its poor heat resistance, persistence are poor, easily ooze out, toxicity is big.And day
Right antiseptic has not been achievable the large-scale marketization because its security, the acquisition of raw material and processing conditions are restricted.Nothing
Machine anti-biotic material is mainly the anti-biotic material obtained from the metals such as gold, silver, copper, zinc antibacterial ability in itself, and the material has
There are heat resistance, hypotoxicity, sustained anti-microbial, has a broad antifungal spectrum, be the study hotspot of current anti-biotic material.To silver in the present invention
Antiseptic carries out functional modification, makes it good with plastic substrate compatibility, and do not influence its antibacterial effect.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of high tenacity antibiotic plastic, not only with good antibacterial energy
Power, while have excellent mechanical performance and processing characteristics concurrently.
A kind of high tenacity antibiotic plastic of present invention offer, including polyphenylene oxide, polystyrene, antimicrobial powder, styryl are common
Polymers or maleic anhydride modified styrene-based copolymers.
Specifically, the high tenacity antibiotic plastic is made up of the raw material of following parts by weight：Polyphenylene oxide 15-30 parts by weight, gather
Styrene 70-90 parts by weight, antimicrobial powder 1-2 parts by weight, styrene-based copolymers or maleic anhydride modified styryl are total to
Polymers 20-30 parts by weight.
The styrene-based copolymers be styrene-(Ethylene/Butylene)-styrene block copolymer, methacrylate-
It is one or more of mixed in butadiene-styrene Core shell nanoparticles, acrylnitrile-butadiene-styrene copolymer
Compound.
As the improved technical scheme of the present invention, the preparation of the maleic anhydride modified styrene-based copolymers
Process is：By styrene-based copolymers in 70-80 DEG C of dry 8-10 hour；By dried styrene-based copolymers and maleic acid

It is seen from the above data that the performance of embodiment 2-4 high tenacity antibiotic plastic is changed compared to embodiment 1
Kind, this is probably due to embodiment 2-4 and styrene-based copolymers is carried out with maleic anhydride modified, modified styryl copolymerization
Thing can increase-volume polyphenylene oxide phase and polystyrene phase, while strengthen the cohesive force between two-phase matrix, wherein the effect of embodiment 3
Preferably.Embodiment 5 irradiates before grafting to styrene-based copolymers, improves the grafting rate of styrene-based copolymers,
This is advantageous to the raising of plastics mechanical property.Generally it is directly added into the prior art using Argent grain as antimicrobial powder in plastics,
Dispersiveness and poor compatibility of the Argent grain in macromolecule matrix, and Argent grain is easily bad with the organic matter generation in plastics
Reaction so that plastic products color is in grey black, and which has limited its use in white domestic appliances.And 1-5 of the embodiment of the present invention
It is middle to be modified silver nano-grain as antimicrobial powder, the oleic acid and n-propylamine using oleic acid and n-propylamine modification silver nano-grain and pass through
Sol-gel method reduces its surface in one layer of nano-Ag particles Surface coating and polymer similar in plastic substrate solubility parameters
Can, increase its compatibility with polymer, the compatibility of antimicrobial powder and polymer can be increased substantially, so that antimicrobial powder
It is dispersed in polymeric matrix, while be also prevented from and delayed in antimicrobial powder between silver particles and high molecule plastic not
Good reaction.Embodiment 6 is used as antimicrobial powder using curcumin silver nano-grain, and the oxygen in curcumin ketone group is coordinated with silver-colored
Effect, curcumin is set to be wrapped in silver nano-grain surface, while hydroxyl in curcumin molecule and methoxyl group are retained, and
Hydroxyl and methoxyl group play an important role to the antibiotic effect of curcumin.
The foregoing is only presently preferred embodiments of the present invention, all equivalent changes done according to scope of the present invention patent with
Modification, it should all belong to the covering scope of the present invention.
