Abstract
The invention discloses a formula of medical rubber bungs. The medical rubber bungs are manufactured from the components of, by weight: 1000 parts of medical artificial rubber, 40 parts of medical zinc oxide, 10 parts of medical stearic acid, 10 parts of a medical anti-aging agent, 1.5-2 parts of medical insoluble sulfur, 0.5-1 part of a medical thiazole promoter, 0.3-0.9 parts of a medical sulfenamide promoter, and 0.2-0.6 parts of medical dithio-tetrabenzyl-thiuram. The formula is advantaged in that: 1, the medical dithio-tetrabenzyl-thiuram is used for replacing a rubber promoter TMTD, such that the rubber bungs do not precipitate carcinogenic nitrosamines; 2, artificial polyisoprene is adopted, such that allergy caused by substances such as plant rennet contained in natural rubber is avoided; and 3, medical white carbon black and medical calcined kaolin are adopted, such that the puncture tolerance of the rubber bungs is improved.
Description
Technical field:
The present invention relates to a kind of formula of medical grade rubber plug.
Background technology:
Rubber product is because having good elasticity and sealing property defendant to be widely used in electronic industry, building trade, automotive industry, daily life, medical industry and the sky industry of aviation row etc.On medical industry, generally have as in conduit, plug and beauty treatment, this just requires material non-toxic, good with biocompatible, does not produce secondary pollution.But the medical grade rubber plug generally used at present, owing to containing rubber accelerator TMTD, can produce poisonous nitrosamine in the process of using, and anti-punctural is bad, easily causes again allergy.
Summary of the invention:
The objective of the invention is in order to overcome the shortcoming of above-mentioned prior art, provide a kind of safe, do not produce carcinogens, anti-acupuncture, and nonallergenic medical grade rubber plug formula.
Goal of the invention of the present invention can realize by following technical scheme: a kind of formula of medical grade rubber plug, its composition is as follows according to weight proportion: 1000 parts of medical artificial rubber, 40 parts, medical zinc oxide, 10 parts of medical stearic acid, 10 parts of medical protective agents, 1.5～2 parts of medical insoluble sulfurs, 0.5～1 part of medical thiazole accelerator, 0.3～0.9 part of medical sulfenamide type accelerators, 0.2～0.6 part of medical tetra-benzyl thiram disulfide.
Also include 100 parts of medical white carbon blacks, 500 parts of medical calcined kaolins.
Also include 10 parts of medical glycol ethers.
Also include 120 parts of medical white mineral oils.
Medical thiazole accelerator is dibenzothiazyl disulfide.
Medical sulfenamide type accelerators is N cyclohexyl 2 benzothiazole sulfenamide.
After adopting the technical program, the invention has the beneficial effects as follows:
1. adopt medical tetra-benzyl thiram disulfide to replace rubber accelerator TMTD, can make rubber plug not separate out carcinogenic nitrosamine material;
2. adopt artificial polyisoprene, can avoid containing because of natural rubber the materials such as plant protease and cause allergic reaction:
3. adopt medical white carbon black and medical calcined kaolin, can improve the anti-punctural of rubber plug.
Embodiment:
Below in conjunction with accompanying drawing, the present technique patent is described further.
