Embodiment 1

[0013] The present invention is formed by mixing the following raw materials according to weight percentage: 40% of butyl rubber, 20% of ethylene-propylene copolymer, 30% of filler, 9% of phenolic resin, 1% of coloring agent, and the filler consists of pottery clay, talcum powder, white carbon Black is mixed in a weight ratio of 2:1:1; the viscosity-average molecular weight of butyl rubber is 80,000, the Mooney viscosity ML1+8 (100 °C) is 40 to 70, and the degree of unsaturation is 0.7~1.5mol%. The melting point of ethylene-propylene copolymer is ≤120°C. The preparation method is that the above-mentioned materials are kneaded in a mixer, mixed at 130°C to 190°C, preferably at 140°C to 160°C, and molded by compression molding or injection molding.

Embodiment 2

[0015] The present invention is formed by mixing the following raw materials according to weight percentage: 30% of butyl rubber, 15% of ethylene-propylene copolymer, 50% of filler, 3.5% of phenolic resin, 1.5% of coloring agent, and the filler consists of clay, talcum powder, white carbon Black is mixed in a weight ratio of 2:1:1; the viscosity-average molecular weight of butyl rubber is 80,000, the Mooney viscosity ML1+8 (100 °C) is 40 to 70, and the degree of unsaturation is 0.7~1.5mol%. The melting point of ethylene-propylene copolymer is ≤120°C. The preparation method is that the above-mentioned materials are kneaded in a mixer, mixed at 130°C to 190°C, preferably at 140°C to 160°C, and molded by compression molding or injection molding.

Embodiment 3

[0017] The present invention is formed by mixing the following raw materials according to weight percentage: 40% of butyl rubber, 10% of styrene-based elastomer, 50% of filler, 9.5% of phenolic resin, 0.5% of colorant, and the filler consists of clay, talcum powder, white carbon Black is mixed in a weight ratio of 2:1:1; the viscosity-average molecular weight of butyl rubber is 80,000, the Mooney viscosity ML1+8 (100 °C) is 40 to 70, and the degree of unsaturation is 0.7~1.5mol%. The melting point of ethylene-propylene copolymer is ≤120°C. The preparation method is that the above-mentioned materials are kneaded in a mixer, mixed at 130°C to 190°C, preferably at 140°C to 160°C, and molded by compression molding or injection molding.

Abstract

The invention relates to a rubber material and particularly relates to an oral liquid rubber plug material and a preparation method thereof. The rubber plug material is formed by mixing the following raw materials by weight: 20%-40% of synthetic rubber, 10%-20% of thermoplastic elastomer, 30%-50% of fillers, 3%-10% of cross-linking agents and 0.5%-1.5% of coloring agents, wherein the synthetic rubber is butyl rubber, polyisobutene rubber or halogenated butyl rubber; the thermoplastic elastomer is cinnamenyl elastomer or polyolefin thermoplastic elastomer; the fillers are one or more of syderolite, talc powders and white carbon black; the cross-linking agents are metallic oxides or phenolic resins; and the coloring agents are titanium dioxide, carbon black or a mixture of the titanium dioxide and the carbon black. The prepared oral liquid rubber plug material is good in mechanical strength and elasticity and capable of meeting usage requirements and processing requirements of an oral liquid rubber plug and also meeting requirements of compatibility with contacted liquid drugs after sealing.

Description

technical field [0001] The invention relates to a chemical material, in particular to a rubber stopper material for oral liquid and a preparation method thereof. Background technique [0002] There are many kinds of rubber stoppers for oral liquids currently used in the market, and the materials are various. However, the material properties of the existing rubber stoppers for oral liquids are not good, and there are defects such as high processing difficulty and poor sealing performance, and some of them also release some odors, which affect the mouthfeel of oral liquids and cause certain impacts on users. Contents of the invention [0003] The purpose of the present invention is to provide a new type of oral liquid rubber stopper material for the defects of the existing oral liquid rubber stopper material formula, which can not only meet the use requirements and processing requirements of oral liquid rubber stoppers, but also meet the requirements of the contact surface a...
