Description
Technical field
The present invention relates to a kind of PVC stiff sheet suitable for 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 drug bubble-cap field.
Natural products and Chinese medicine preparation are since it contains a large amount of organic compound, can be by preserving process
Mould, the pollution of actinomyces, shorten its shelf-life.In producing high-molecular when the way of current common antibacterial PVC stiff sheet is batch mixing
It closes in object and adds in a kind of inorganic compound of antibacterial, then calendering formation, so that stiff sheet surface covers the nothing of one layer of antibacterial
Machine compound layer.The inorganic compound of known antibacterial generally comprises the antibacterial ion in alum and zeolite, i.e., in existing doctor
In drug package, one layer of antibiotic layer is formed by adding alum or zeolite in existing high-molecular compound.But it has to
, it is noted that microgranular antiseptic, due to that can not disperse well, it is therefore possible to can influence the clear degree of stiff sheet, resist
Atomization etc., while adhesion property is can also affect on, this actual use that will be seriously affected in packaging finally influences its business
Value.Simultaneously during stiff sheet use is packed, heating is so that the Micro Amounts of Chlorine that PVC is released mutually is tied with metal ions such as silver
It closes, certain influence can be also generated to antibiotic layer on the barrier layer that stiff sheet surface is formed.The antibacterial inorganic chemical combination of addition simultaneously
The amount of object also must be suitable, because of its physical property, if excessive addition, it is possible to cause the non-machinable of final finished and make
With.
In addition, due to PVC strands, there are faults of construction, and hydrogen chloride, the hydrogen chloride of releasing can be deviate from when being heated to 110 DEG C
It can accelerate the decomposition of PVC again, therefore in 160 DEG C -200 DEG C of processing temperature obvious degradation can occur for PVC, cause the discoloration of product
With the declines such as products machinery performance, service life is influenced.To prevent PVC from degrading in process, need to add in heat surely
Determine agent.
In addition, in medicine field, since drug is more sensitive to ultraviolet light, easily chemically react, therefore, drug is not
Can be chronically at daylight (containing ultraviolet light) irradiation under, but due to not everyone can clear and specification to medicine
Product are stored, and it is very necessary that the Key works Drug packing, which has anti-ultraviolet function,.Bubble-cap is as very heavy in Key works Drug packing
A kind of packaged form wanted is typically what is formed by plastics by modes such as plastic uptakes, and bubble-cap is transparent, does not have to ultraviolet light
Interception function, in drug the quality of drug can be influenced if Long Term Contact to daylight.
From the foregoing, it will be observed that for the PVC stiff sheet of medical packaging, clear degree, anti-fog performance are not only needed, it is also necessary to
There are good antibiotic property, thermal stability, ultraviolet interception function and the good gas barrier properties to oxygen, vapor.At present,
The PVC stiff sheet for medical packaging of various excellent performances can be taken into account by also rarely having, this may be due to a kind of functional materials
Add in the performance for more or less influencing whether other functional materials performances.In addition, current PVC antiseptics or heat stabilizer
Wait complicated components, this undoubtedly in increase prepare take into account various excellent performances PVC stiff sheet difficulty.
Invention content
It is above-mentioned in order to solve the problems, such as, it takes into account high clear degree simultaneously the present invention provides one kind, thermostabilization, resist
Atomization antibiotic property, obstructs the antibacterial PVC stiff sheet suitable for medical packaging of the functions such as ultraviolet, and need to only use less
