Description
Technical field
The present invention relates to medical material tech field more particularly to a kind of preparation methods of the medical plastics of resistance to enzyme.
Background technology
PET plastic is the abbreviation of English Polyethylene terephthalate, abbreviation PET or PETP.The Chinese meaning
It is：Poly terephthalic acid class plastics include mainly polyethylene terephthalate PET and polybutylene terephthalate PBT.It is poly-
Ethylene glycol terephthalate is commonly called as polyester resin again.It is the condensation polymer of terephthalic acid (TPA) and ethylene glycol, is referred to as together with PBT
For thermoplastic polyester or saturated polyester.
Steam penetrating capacity must not cross 0.2% by experimental condition liquid oral plastic drug package weight loss：By experimental condition
The medicinal plastic bottle vapor permeation amount of oral administration solid must not cross 1000mg/24h L.
It is reported according to data, the disposable health care article consumption figure in Europe in 1998 is up to 35,000,000,000 dollars.Wherein,
Medical plastic PVC accounts for larger specific gravity, and still, polyolefin and PVC thermoplastics will be reduced year by year from now on, and engineering plastics will
Increase.
At past 20 years, to health care's attitude huge change occurred for Asia-Pacific consumer, and this is mainly due to economy
The raising of development and living standard and education degree.More and more consumers and patient are ready understanding medical industry, and
It is ready to buy Health Care Services, such as self diagnosis tool.That is the other polyvinyl chloride of medical grade.
PET plastic molecular structure high degree of symmetry has certain crystalline orientation ability, so with higher film forming and
It becomes second nature.There is PET plastic good optical property and weatherability, amorphous PET plastic to have good optical transparence.Separately
Outer PET plastic has excellent abrasion performance frictional property and dimensional stability and electrical insulating property.The bottle that PET makes have intensity it is big,
Good, nontoxic, the impermeable, light weight of the transparency, production efficiency height etc. thus receive and be widely applied.PBT is chained with PET molecules
Structure is similar, and most of property is also the same, and only molecular backbone becomes four by two methylene, so molecule is more soft
Suitable, processing performance is more excellent.
PET is the polymer of milky or light yellow highly crystalline, smooth surface and it is glossy.It is creep resistance, antifatigue
Property, rub resistance it is good, abrasion are small and hardness is high, with maximum toughness in thermoplastic；Electrical insulation capability is good, by temperature shadow
Sound is small, but corona resistance is poor.Nontoxic, against weather, chemical proof stability are good, and hygroscopicity is high, and the drying before molding is
It is necessary.Weak acid resistant and organic solvent, but intolerant to hot-water soak, it is not alkaline-resisting, design a kind of medical plastics of resistance to enzyme that sterilizing rate is good
It is very important.
