Abstract
The present invention relates to a kind of medicinal pad, specifically a kind of proof medical synthesized polyisoprene gasket.It is mixed according to parts by weight by following raw material: 100 parts of polyisoprene rubbers, 0.01～0.02 parts by weight of carbon black per, 1～3 parts by weight of crosslinking agent, 3～5 part by weight of zinc oxide or organic zincs, 1～3 weight portion stearic acid, 1～3 weight portion accelerator, 20～30 parts by weight of filler, 1～3 weight portion softening agents.The present invention can meet use requirement and the processing request of isoprene pad, requirement to the liquid medicine compatibility contacted after disclosure satisfy that again sealing.It is not required to extract through chemistry, and product cleanliness factor is higher, preferable with the medicinal liquid compatibility.
Description
Technical field
The present invention relates to a kind of medicinal pad, specifically a kind of proof medical synthesized polyisoprene gasket.
Background technology
The most widely used proof medical synthesized polyisoprene gasket is required for greatly extracting through chemistry, and chemistry
Still there is some index can not be up to standard after extracting, and chemistry extracting exists the risk of secondary pollution, discharge after extracting
Soda acid pollutes environment, also has chemistry extracting to too increase certain production cost.
Summary of the invention
Present invention is aiming at that current polyisoprene rubber pad needs extracting, chemical index is underproof asks
Topic, it is provided that a kind of exempt from chemistry extracting, the formula of ultra-clean isoprene rubber pad.It can meet making of isoprene pad
With requiring and processing request, requirement to the liquid medicine compatibility contacted after disclosure satisfy that again sealing.Present invention maximum
Innovative point is that provided isoprene pad is not required to through chemistry extracting, and product cleanliness factor is higher, compatible with medicinal liquid
Property is preferable.
The technical scheme is that and be achieved in that: it is mixed according to parts by weight by following raw material: 100 parts gather
Isoprene rubber, 0.01～0.02 parts by weight of carbon black per, 1～3 parts by weight of crosslinking agent, 3～5 part by weight of zinc oxide or organic zincs, 1
～3 weight portion stearic acid, 1～3 weight portion accelerator, 20～30 parts by weight of filler, 1～3 weight portion softening agents.Described friendship
Connection agent is phenolic resin class cross-linking agent.The number-average molecular weight of described polyisoprene rubber is 40 ten thousand to 70 ten thousand to arrive, and Mooney glues
Degree ML 1+4 (100 DEG C) 50 to 90.
Filler is typically selected and is made up of potter's clay, Pulvis Talci, white carbon, calcium carbonate etc.；Cross-linking agent is typically chosen phenolic aldehyde tree
Fat or sulfur etc.；Activating agent is typically chosen metal-oxide and (or) stearic acid, coloring agent is typically chosen titanium dioxide and carbon black.
The material of the polyisoprene rubber used in this patent includes, those have number-average molecular weight is 400,000 to arrive
700000 arrive, and preferably 500,000；Mooney viscosity ML 1+4 (100 DEG C) 50 to 90, preferably 60 to 80,
In order to complete polyisoprene rubber pad formula as above, each material mixes at banbury, at 110 DEG C
To 150 DEG C, preferably mix at 120 DEG C to 140 DEG C, with compression molding or injection system molding.
The present invention can meet use requirement and the processing request of isoprene pad, to being connect after disclosure satisfy that again sealing
The requirement of the liquid medicine compatibility touched.It is not required to extract through chemistry, and product cleanliness factor is higher, with the medicinal liquid compatibility relatively
Good.
