The invention relates to a chemical material, and particularly relates to a material for blood specimen collection and a preparation method thereof. The material for blood specimen collection is prepared by mixing the following raw materials in percentage by weight: 20-40% of synthetic rubber, 10-20% of thermoplastic elastomer, 30-50% of filler, 3-10% of crosslinking agent and 0.5-1.5% of colorant, wherein the synthetic rubber is butyl rubber, polyisobutylene rubber or halogenated butyl rubber; the thermoplastic elastomer is styryl elastomer or polyolefin thermoplastic elastomer; the filler is one or more of argil, talcum powder and white carbon black; the crosslinking agent is metal oxide or phenol formaldehyde resin; and the colorant is titanium white, carbon black or a mixture thereof. According to the invention, the prepared rubber plug material for an oral liquid has good mechanical strength and elasticity, can meet the operation requirements and processing requirements of the rubber plug for an oral liquid, and can also meet the requirements for the compatibility of liquid medicine which is in contact with the rubber plug after sealing.
Description
Technical field
The present invention relates to a kind of elastomeric material, specifically a kind of blood sample collection plug material and preparation method thereof.
Background technology
The blood sample collection that existing market is used is a lot of with the plug kind, and material is various.But existing oral liquid is bad with the material property of plug, has the large and bad defective of sealing property of difficulty of processing, and some smells of also release that have affect for user of service's meeting.
Summary of the invention
The object of the invention is exactly the defective for existing oral liquid rubber stopper material prescription, a kind of blood sample collection plug material is provided, it can either satisfy service requirements and the processing request of oral liquid rubber stopper, can satisfy again after the sealing requirement to the liquid medicine compatibleness that contacts.
Technical scheme of the present invention is such realization: it is mixed according to weight percent by following raw material:
Synthetic rubber 20%-40%, thermoplastic elastomer 10%-20%, filler 30%-50%, linking agent 3%-10%, tinting material 0.5%-1.5%, wherein synthetic rubber is isoprene-isobutylene rubber, polyisobutylene rubber or halogenated butyl rubber; Thermoplastic elastomer is styrene-based elastomer or polyolefins thermoplastic elastomer; Filler is one or more in potter's clay, talcum powder, the white carbon black; Linking agent is metal oxide or resol; Tinting material is titanium dioxide, carbon black or its mixture.
The present invention preferably technical scheme is: the viscosity-average molecular weight of described isoprene-isobutylene rubber is 1.5 ten thousand to 200,000, mooney viscosity ML1+8(100 ° C) degree of unsaturation of 20 to 100,0.3 3.0 mol%.The viscosity-average molecular weight of preferred described isoprene-isobutylene rubber is 80,000, mooney viscosity ML1+8(100 ° C) degree of unsaturation of 40 to 70,0.7 1.5mol%.1+8(100 ° of C of the mooney viscosity ML of described halogenated butyl rubber) degree of unsaturation of 20 to 100,0.1 3.0 mol%, the weight ratio of content of halogen are 0.5% 3.0%.1+8(100 ° of C of the mooney viscosity ML of preferred described halogenated butyl rubber) degree of unsaturation of 40 to 70,0.7 2.0 mol%, the weight ratio of content of halogen are 0.5% 3.0%.The fusing point of described thermoplastic elastomer≤120 ° C.
Described polyolefin elastomer is ethylene-propylene copolymer or non-altogether ethylene-propylene-diene copolymer.
The better technical scheme of the present invention is such realization: it is mixed according to weight percent by following raw material:
Isoprene-isobutylene rubber 20%-40%, ethylene-propylene copolymer 10%-20%, filler 30%-50%, resol 3%-10%, tinting material 0.5%-1.5%, filler is mixed according to the part by weight of 2:1:1 by potter's clay, talcum powder, white carbon black; The viscosity-average molecular weight of isoprene-isobutylene rubber is 80,000, mooney viscosity ML1+8(100 ° C) degree of unsaturation of 40 to 70,0.7 1.5mol%.
Isoprene-isobutylene rubber mainly is the barrier properties for gases to a satisfaction among the present invention.If the isoprene-isobutylene rubber consumption is less than 20% weight, just can not provide the gas barrier property of a satisfaction as the oral liquid rubber stopper material.Because it is low that isoprene-isobutylene rubber has larger compression set, impelling strength and hardness, tension set is large.Therefore, the effect of thermoplastic elastomer is the physicals that improves plug.In the weight range of thermoplastic elastic scale of construction decline 10% to 20%.If the thermoplastic elastic scale of construction surpasses total amount 20%, the impact of isoprene-isobutylene rubber possibly can't obtain.On the other hand, if the thermoplastic elastic scale of construction less than 10% weight, the impact of thermoplastic elastomer is may not can satisfactory.In sum, the physical strength of the material for preparing under prescription condition of the present invention is best, and elasticity is also fine, and it can either satisfy service requirements and the processing request of oral liquid rubber stopper, can satisfy again after the sealing requirement to the liquid medicine compatibleness that contacts.Preparation method of the present invention is to be to rub in a stirrer with each material, at 130 ° of C to 190 ° of C, is preferably in 140 ° of C to 160 ° of C and mixes, with compression molding or injection system moulding.
