Abstract
The invention discloses a PP (polypropylene) and PET composite antibacterial plastic alloy, which includes the following components in parts by weight: 100 parts of PP, 15-25 parts of PET, 6-8 parts of EPDM-g-GMA and 0.6-0.8 part of antibacterial agent. The PP and PET composite antibacterial plastic alloy provided by the invention is excellent in antibacterial effect.
Description
Technical field
The present invention relates to a kind of polyblend, relate in particular to the antibiotic plastic alloy that a kind of PP and PET are compound.
Background technology
Polypropylene, English name: Polypropylene, be called for short: PP.Polypropylene is lighter a kind of in common plastics, and its electrical property excellence can be used as the application of wet-heat resisting high-frequency insulation material.
PET, poly terephthalic acid class plastics, mainly comprise polyethylene terephthalate PET and polybutylene terephthalate PBT.The PET plastics have good optical property and weathering resistance, and amorphous PET plastics have good optical transparence.The PET plastics have good abrasion performance frictional property and dimensional stability and electrical insulating property in addition.
Yet the polyblend anti-microbial property that current PP and PET are compound is not good.
Summary of the invention
For above shortcomings in prior art, technical problem to be solved by this invention is to provide a kind of PP and the compound antibiotic plastic alloy of PET.
Technical problem to be solved by this invention is achieved by the following technical solution:
The antibiotic plastic alloy that PP and PET are compound consists of by weight following component: 100 parts of PP, 15-25 part PET, 6-8 part EPDM-g-GMA, 0.6-0.8 part antiseptic-germicide.
Described expanding material EPDM-g-GMA is the terpolymer EP rubber graft glycidyl methacrylate.
Described antiseptic-germicide consists of by weight following component: zirconium phosphate 10-30 part, silver suboxide 20-40 part, chitosan 10-30 part, 2-thiazolyl-4-benzoglyoxaline 20-40 part.
Zirconium phosphate, English name: Phosphoric acid, zirconium (4+) salt (2:1), CAS Number:13772-29-7.
Silver suboxide, CAS Number:20667-12-3.
Chitosan, English name: Chitosan, CAS Number:9012-76-4.
2-thiazolyl-4-benzoglyoxaline, English name: 2-(4-thiazolyl) benzimidazole, CASNumber:148-79-8.
Zirconium phosphate, silver suboxide, chitosan and 2-thiazolyl-4-benzoglyoxaline are uniformly mixed, can make described antiseptic-germicide.
Can adopt industry universal method to be prepared PP of the present invention and the compound antibiotic plastic alloy of PET, for example: take each component by proportioning, after mixing, melting mixing, extruding pelletization, obtain the antibiotic plastic alloy that described PP and PET are compound.
The antibiotic plastic alloy that PP of the present invention and PET are compound, the antibacterial effect excellence.
