Abstract
The invention provides a polyisoprene gasket composition for injection, relating to the technical field of medical supplies. The composition is characterized in that the composition comprises the following components in parts by weight: 30-40 parts of polyisoprene, 25-35 parts of natural rubber, 10-20 parts of pottery clay, 1-3 parts of zinc oxide, 0.5-1 part of vaseline, 0.5-2 parts of silicone oil, 1-2 parts of titanium dioxide and 0.01-0.5 part of carbon black. The composition has the beneficial effects that the composition has simple components and is convenient to prepare; and the prepared gasket has good sealability, is environment-friendly and hygienic, is pollution-free, has low content of volatile matters and high intrinsic cleanliness and ensures the quality safety of liquor.
Description
Technical field
The present invention relates to the medical supplies technical field, be specifically related to a kind of injection liquid polyisoprene gasket composition.
Background technology
The rubber of producing at present medicinal butyl rubber bottle stopper mainly contains chlorinated butyl rubber and brominated butyl rubber, contain have an appointment 97-99% iso-butylene and 1-3% isoprene in the molecular structure of these rubber, 1.8-2.2% chlorine atom or bromine atoms are arranged in the molecular structure.Usually utilize when selecting vulcanizing agent that content two keys and halogen atom seldom carries out crosslinked in chlorinated butyl rubber and the brominated butyl rubber molecular structure, usually the vulcanizing agent kind that adopts has zinc oxide, sulphur, sulfur derivative, alkyl phenolic resin, magnesium oxide, aminated compounds etc., the curing system that adopts this rubber and be complementary still can meet the demands on the insensitive medicine of some conventional parts.But because of fill a prescription complexity and add the relation of starting material concentration gradient, after the more intense drug pack of some molecular activities, by drug absorption, absorption, leaching, infiltration, produced the compatibility problem of plug and medicine, relatively more outstanding is part cephalosporins, part infusion solutions class and more Chinese medicine injection liquid formulation etc.As the common halogenated butyl rubbers that use in a large number at present, because the needs of process for processing, all be added with 1-isobutenyl-2,2,4, the chemical additives such as the C13 oligopolymer such as 4-tetramethyl-ring hexane, BHT (Yoshinox BHT), ESBO (epoxy soybean oil), Zinic stearas, calcium stearate, these materials have judged by analysis that the consistency on medicine has some impacts.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of performance good, uses the injection liquid polyisoprene gasket composition of safety.
Technical problem to be solved by this invention realizes by the following technical solutions:
A kind of injection liquid polyisoprene gasket composition is characterized in that: the component by following mass parts forms,
Best in quality part of each component is:
The invention has the beneficial effects as follows: component of the present invention is simple, and is easy to prepare, and the gasket seal performance of making is good, and environmentally-friendly sanitary is pollution-free, and volatile content is very low, and inherent cleanliness factor is very high, guarantees the quality safety of liquid.
