Description
Technical field
The present invention relates to a kind of antibiotic plastic and preparation method thereof, relate in particular to a kind of antibiotic HIPS plastics and preparation method thereof.
Background technology
Along with the fast development of industry and improving constantly of living standards of the people, people are to environmental health and self-healthy pay attention to day by day.Mikrobes such as natural unwanted bacteria, fungi and virus are the major causes that makes the mankind infected, induce an illness.Cause that in mid-term 14th century of Christian era Europe 1/3rd human mortalities' Bubonic plague and 20 beginnings of the century cause the dead influenza of the whole world more than 2,000 ten thousand people; Infect syndromes SARS at the pathogenicity bo intestinal bacteria " O-157 " of Japanese nationwide, " mad cow disease ", " foot and mouth disease " of Britain, " anthrax " of the U.S. and the serious acute respiratory of spring and summer appearance in 2003, these transmissible diseases all have direct relation with pathogenic micro-organism.
Along with growth in the living standard, people are also increasingly high to the requirement of living environment.Thus, the production of anti-biotic material has become an emerging industry, and countries in the world antagonism Research of Microorganisms Agent is paid attention to more.
Antibiotic plastic is meant and in plastics, adds antiseptic-germicide; Make plastics itself have bacterinertness, can within a certain period of time the bacterium of contamination on plastics be killed or suppress, compare with physical method with the chemistry of routine; Use antibiotic plastic sterilization timeliness long, not only economy but also make things convenient for.Antiseptic-germicide can divide inorganic, organic and 3 types of natural biological antiseptic-germicides.Because different antiseptic-germicide is different to the anti-microbial effect mechanism of pathogenic bacteria of the same race and validity; And antiseptic-germicide of the same race is also different with the inhibition scope for the anti-microbial effect mechanism of different pathogenic bacterias; Therefore; Work out not only long-acting but also wide spectrum, not only efficient but also safe antiseptic-germicide, very important to the research of antibiotic mechanism.
The HIPS plastics, full name High Impact Polystyrene, Chinese is an impact resistant polystyrene, is a kind of engineering plastics.Impact resistant polystyrene is to gather a kind of shock proof polystyrene products that butyl rubber particulate way is produced through in PS, adding.This polystyrene products can add micron order rubber grain and the way through scion grafting and link together PS and rubber grain when receiving when impacting, and the point stresses of crack propagation can be discharged by softish rubber grain relatively.Therefore the expansion of crackle is hindered, and shock resistance is improved.Impact resistant polystyrene is a kind of broad-spectrum brittle plastic.
At present, a kind of HIPS plastics are not arranged, can be effectively antibiotic.
Summary of the invention
To the above-mentioned deficiency that exists in the prior art, one of technical problem to be solved by this invention provides antibiotic HIPS plastics.
Two of technical problem to be solved by this invention provides the preparation method of above-mentioned antibiotic HIPS plastics.
The present invention realizes through following technical scheme:
Antibiotic HIPS plastics comprise following components by part by weight: HIPS100 part, antiseptic-germicide 0.3-0.5 part, dispersion agent 0.2-0.4 part.
Wherein,
Said antiseptic-germicide is a kind of or its mixture in nano cupric oxide, nano phase ag_2 o, polyhexamethylene guanidine phosphoric acid salt and N-(trichloro-methylthio) phthalic imidine.
Said antiseptic-germicide is made up of following component: nano cupric oxide 25-35 part, nano phase ag_2 o 30-50 part, polyhexamethylene guanidine phosphoric acid salt 4-8 part, N-(trichloro-methylthio) phthalic imidine 2-6 part by weight.Nano cupric oxide, nano phase ag_2 o, polyhexamethylene guanidine phosphoric acid salt and N-(trichloro-methylthio) phthalic imidine are mixed, can make this antiseptic-germicide.
Said dispersion agent is a kind of or its mixture in Triple Pressed Stearic Acid, polyethylene wax, the whiteruss.
The present invention also provides the preparation method of above-mentioned antibiotic HIPS plastics:
Take by weighing each raw material by proportioning, after mixing, melting mixing, extruding pelletization promptly obtain said antibiotic HIPS plastics.
Obviously, for improving other performances of product, can also add other auxiliary agents adaptively, in the present invention like fire retardant, tinting material and oxidation inhibitor etc.
Concrete, in the present invention:
Nano cupric oxide, particle diameter are 10-80nm.
Nano phase ag_2 o, particle diameter are 10-80nm.
N-(trichloro-methylthio) phthalic imidine, N-(Trichloromethylthio) phthalimide, CAS accession number: 133-07-3, chemical structural formula is following:
Polyhexamethylene guanidine phosphoric acid salt, Polyhexamethyleneguanidine phosphate, CAS accession number: 89697-78-9.Chemical structural formula is following:
Triple Pressed Stearic Acid, another name: octadecanoic acid, English name: stearic acid, CAS number: 57-11-4.
Polyethylene wax, another name PE wax is a kind of chemical materials, quality is white little microballon shape/sheet, is formed by vinyl polymerization Rubber processing agent.
Whiteruss, another name: Yellow Protopet 2A, white oil, English name: liquid paraffin.
The antibiotic HIPS plastics of the present invention's preparation; Have broad-spectrum antimicrobial effect, special, the present invention adopts inorganic antiseptic and the composite use of organic antibacterial agent; This complex antimicrobials has combined the advantage of the two; The prompt effect, the persistence that had both had organic antibacterial agent have the security and the discoloration-resistant of inorganic antiseptic again, have also played the effect of synergy antimicrobial simultaneously.
