Description

Medicinal chlorinated butyl rubber bung and its preparation process
Technical field
The present invention relates to a kind of medicinal chlorinated butyl rubber bung and its preparation processes, belong to medicinal bottle stopper Material Field.
Background technique
The vulcanizing system that current the most frequently used chlorinated scoline bottle stopper uses is resin zinc oxide system, but the use of zinc is not Conducive to the cleanliness for promoting bottle stopper, the encapsulation of the drug especially changed greatly to pH value is more unfavorable, in addition in view of oxidation For zinc to the sensibility and incompatibility problem of some drugs, the vulcanizing system that exploitation does not need zinc oxide, which is only, solves the problems, such as this Effective way.
Crosslinking agent B SH is a kind of double sulfydryl salt of not carbon azacyclo-, is applied to when chlorinated scoline as vulcanizing agent, no Effectively crosslinking can be realized to chlorinated scoline by needing to be oxidized zinc, while can promote water resistant, heat resistanceheat resistant and the chemically-resistant of product Property.In the test of the drug strong with antibiotics, especially acid-base property, compatibility is significantly better than the conduct of resin zinc oxide The product of vulcanizing system.That is crosslinking agent B SH has better drug compatibility as the chlorinated butyl rubber bung of vulcanizing agent.
Current field has the following disadvantages in summary:
1, the chlorinated scoline piston of currently used resin curative systems production, the clarity in chemical property detection It is bad, when being easy to cause rubber plug and drug contact, make the risk that there is pollution drug;
2, there is poor heat resistance in the chlorinated butyl rubber bung using resin zinc oxide as vulcanizing system;
3, the resin curative systems of the medicinal chlorinated butyl rubber bung of tradition need to use zinc oxide as activating agent, be unfavorable for bottle stopper Inherent cleanliness, no zinc vulcanizing system can promote the quality of bottle stopper product.
Summary of the invention
The problem to be solved by the present invention is that overcoming the deficiencies of the prior art and provide a kind of medicinal chlorinated butyl rubber bung And its preparation process, use crosslinking agent B SH as vulcanizing agent, uses small amounts magnesium as acid absorbent, as medicinal chlorination fourth The vulcanizing system of base rubber stopper, obtained product clarity is good, when being easy to cause rubber plug and drug contact, makes the presence of pollution drug Risk, be provided simultaneously with good heat resistance.
