AI Technical Summary

Problems solved by technology

Common medical rubber stopper materials are mainly butyl rubber or halogenated butyl rubber, of which butyl rubber has good elasticity and barrier properties, and has good resistance to heat, ozone and chemicals. Among them, due to the compatibility problems with different degrees of drugs, unstable extracts or extracts are often produced, resulting in unstable physical properties of the rubber stopper. At the same time, some drugs will form a liquid film on the medical rubber stopper, resulting in a hanging film and hanging powder, affecting the efficacy of the drug, in addition, there will be a problem of falling debris after the puncture, which increases the unsafety of the drug

Abstract

The invention discloses a safe and stable medicine rubber plug material and a preparing method thereof. The safe and stable medicine rubber plug material is prepared from, by mass, 42-56 parts of butyl rubber, 14-20 parts of silicone rubber, 6-11 parts of polyether ketone, 4-9 parts of methylsuccinic anhydride, 4-8 parts of sodium p-styrenesulfonate, 3-7 parts of fucose, 4-8 parts of aspartic acid, 6-13 parts of 1,5-dimercaptopentane, 2-6 parts of 2-(2-ethoxy carbonyl allyloxy) ethylphosphonic acid, 3-7 parts of tetrabenzylthiuramdisulfide, 3-6 parts of polymethylhydrosiloxane, 4-8 parts of vitamin A palmitate, 5-9 parts of benzoyl peroxide, 4-8 parts of nano-zinc oxide and 15-23 parts of glycerinum. The prepared medicine rubber plug material is high in officinal compatibility and leakproofness and suitable for the pharmaceuticals industry as the rubber plug material is safe, stable and high in compatibility.

Description

technical field [0001] The invention belongs to the field of medical materials, and in particular relates to a safe and stable medical rubber stopper material and a preparation method thereof. Background technique [0002] Pharmaceutical packaging is one of the most important links in the medical industry. Due to the particularity of medical drugs, a good sealing effect is required to prevent the volatilization or leakage of medicines. In the sealing process of medicines, synthetic rubber plugs are most used. Can play a very good sealing effect. Common medical rubber stopper materials are mainly butyl rubber or halogenated butyl rubber, of which butyl rubber has good elasticity and barrier properties, and has good resistance to heat, ozone and chemicals. Among them, due to the compatibility problems with different degrees of drugs, unstable extracts or extracts are often produced, resulting in unstable physical properties of the rubber stopper. At the same time, some drugs ...
