Description

A kind of proof medical synthesized polyisoprene and epoxy resin copolymerization pad

Technical field:

The present invention relates to medicinal rubber pad manufacture method technical field, be specifically related to a kind of proof medical synthesized polyisoprene and epoxy resin copolymerization pad.

Background technology:

Along with the development of society, the rubber item kind being applied to medicine and hygiene fields gets more and more, as various flask for medicinal preparations plug, asepsis injector piston, injection sealant sealing, flexible pipe, conduit, medical air cushion, antiseptic rubber medical gloves, baby nipple, tube for blood transfusion,latex etc.Desirable druggist rubber sundries not only needs to have good physicals, also must ensure nontoxic and have unreactiveness, particularly in body rubber item should have not pathogenic, do not damage adjacent tissue, do not cause the features such as allergy, aging resistance are good.

Traditional druggist rubber sundries is under high temperature, condition of high voltage, and its vulcanization system easily produces and pollutes human body, the exudate of medicament, volatile matter, thus is difficult to prepare the druggist rubber sundries meeting medicine extra best best standard.Existing druggist rubber sundries and preparation method thereof, its complex technical process, the product feature of environmental protection is poor, and safety in utilization is not strong, and work-ing life is lower.

Summary of the invention:

Technical problem to be solved by this invention is to provide a kind of directly to contact medicine, can save the inner cap of combination cover, reduces puncture force and exfoliation probability and can replace medicinal synthesis isoprene pad to pharmaceutical factory's reduction group lid cost.

Technical problem to be solved by this invention adopts following technical scheme to realize:

A kind of proof medical synthesized polyisoprene and epoxy resin copolymerization pad, be made up of following component:

Brominated butyl rubber 60-70 part, calcined kaolin 30-40 part, zinc oxide 3-5 part, E-42 epoxy resin 89-99 part, phenolic aldehyde-nitrile rubber multipolymer 89-99 part, acetone 66-75 part, quadrol 10-15 part, soy-protein 100-120 part, turps 5-7 part, 50% aqueous sodium hydroxide solution 15-20 part, liming 40-50 part, water glass 30-40 part, thiocarbamide 2-5 part, tetracol phenixin 1-2 part, pentachlorophenol 2-5 part, chrysanthemum water 400-450 part, toilet water 10-20 part, flowers and plants rhizome 30-50 root.

A kind of proof medical synthesized polyisoprene and epoxy resin copolymerization pad, its preparation method mainly comprises the following steps:

First soy-protein is under agitation added in chrysanthemum water;

After stirring into serum, add 50% aqueous sodium hydroxide solution, stir rapidly;

Secondaryly add pentachlorophenol, water glass, thiocarbamide, tetracol phenixin, heated and stirred, Heating temperature is 190 DEG C, duration 10 minutes;

Be cooled to 70 DEG C, obtain A mixture;

Get E-42 epoxy resin and phenolic aldehyde-nitrile rubber multipolymer, instillation toilet water, adds 30%A mixture simultaneously, stirs;

Cooling, natural evaporate to dryness, instills turps in evaporate to dryness process, obtains dry block;

Get 70%A mixture and calcined kaolin, be placed in stirrer, heat, add liming simultaneously, 90 DEG C are not stopped heated and stirred;

Get brominated butyl rubber to add fast in stirrer, within 1-2 minute, extract out, be placed in sealed can, stand-by, in sealed can tank, the end, is equipped with flowers and plants rhizome;

Being mixed with zinc oxide, acetone, quadrol by dry block adds in stirrer again, stirs 1-2 hour;

Empty the brominated butyl rubber in sealed can and flowers and plants rhizome after 1-2 hour, pour in sealed can by the mixed solution in stirrer, cooling, stripping and slicing, completes preparation.

In this processing method, its key is agitating procedure, because the pad after stirring has better clarity and ensure that sterility and inside are without bacteriotoxin and noresidue moisture, cleaning in addition after extracting can make the clarity of product, particulate and silicone oil reach processing requirement, such pad directly can contact medicine, and can save combination cover inner cap, reduce puncture force and exfoliation probability, on the other hand reduce group lid cost to pharmaceutical factory; And medicinal pad needs and plastic combination cover assembling uses, medicinal pad directly can not contact medicine, and plastic combination cover must have inner cap, uses and also relatively bothers.

The invention has the beneficial effects as follows: pad prepared by this technique directly can contact medicine, and can save the inner cap of combination cover, reduce puncture force and exfoliation probability, reduce group lid cost to pharmaceutical factory on the other hand.
