Description
Technical field
The present invention relates to a kind of PVC stiff sheet being applied to medical packaging, belong to medical packaging field of material technology.
Background technology
PVC packaging stiff sheet is used widely in field of medicaments, especially in medicine bubble-cap field.
Natural product and Chinese medicine preparation contain substantial amounts of organic compound due to it, therefore in preserving process, can be subject to
Mycete, actinomycetic pollution, shorten its shelf-life.The way of common antibacterial PVC stiff sheet is in producing high-molecular during batch mixing at present
A kind of inorganic compound of antibacterial is added, then calendering formation is so that stiff sheet surface covers the nothing of one layer of antibacterial in compound
Machine compound layer.The inorganic compound of known antibacterial generally comprises the antibacterial ion in Alumen and zeolite, that is, in existing doctor
In drug package, one layer of antibiotic layer is formed by interpolation Alumen or zeolite in existing macromolecular compound.But have to
It is noted that particulate antibacterial is due to disperseing well, it is therefore possible to the clear degree of stiff sheet can be affected, resist
Atomization etc., can also affect on adhesion property simultaneously, and this is actually used in packaging by having a strong impact on, its business of final impact
It is worth.Simultaneously during packaging stiff sheet uses, heating makes the Micro Amounts of Chlorine that PVC discharges tie with metal ion phases such as silver
Close, the barrier layer that it forms on stiff sheet surface also can produce certain impact to antibiotic layer.The antibacterial inorganic chemical combination simultaneously adding
The amount of thing also must be suitable, because its physical property, if excessive addition is it is possible to causing the non-machinable of final finished and making
With.
Further, since PVC strand has fault of construction, it is heated to when 110 DEG C deviating from hydrogen chloride, the hydrogen chloride of releasing
The decomposition of PVC can be accelerated, therefore PVC can occur obvious degradation in 160 DEG C -200 DEG C of processing temperature, causes the variable color of product again
Decline with products machinery performance etc., affect service life.For preventing PVC from degrading in process, need to add heat steady
Determine agent.
Additionally, in medicine field, because medicine is more sensitive to ultraviolet, easily there is chemical reaction, therefore, medicine is not
Can be chronically under daylight (containing ultraviolet) irradiates, but due to not everyone can clear and specification to medicine
Product are stored, and it is very necessary that described drug packaging has anti-ultraviolet function.Bubble-cap is as very heavy in drug packaging
A kind of packaged form wanted, it is typically formed by modes such as plastic uptakes by plastics, and bubble-cap is transparent, ultraviolet is not had
Interception function, if its interior medicine Long Term Contact, to daylight, can affect the quality of medicine.
From the foregoing, it will be observed that for medical packaging PVC stiff sheet, not only need clear degree, anti-fog performance in addition it is also necessary to
Good antibiotic property, heat stability, ultraviolet is had to intercept function, and the good gas barrier properties to oxygen, vapor.At present,
Also rarely has the PVC stiff sheet for medical packaging that can take into account various premium properties, this is likely due to a kind of functional materials
Add the performance more or less influencing whether other functions material performance.Additionally, current PVC antibacterial or heat stabilizer
Deng complicated component, this undoubtedly in increase the difficulty that preparation takes into account the PVC stiff sheet of various premium properties.
Content of the invention
In order to solve above-mentioned problem, the invention provides one kind takes into account high clear degree, thermally-stabilised, anti-simultaneously
The antibacterial PVC stiff sheet being applied to medical packaging of the functions such as atomization, antibiotic property, obstruct ultraviolet, and only need to use less
