Abstract
The invention discloses a reclaimed EPDM rubber mixed rubber sealing ring which is prepared by carrying out banburying, open refining and secondary vulcanization on the raw materials of reclaimed EPDM rubbe, cis-butadiene rubber, styrene-butadiene rubber and the like. The reclaimed EPDM rubber mixed rubber sealing ring provided in the invention has the advantages of good extensibility, excellent high temperature resistance and low temperature resistance, high tensile strength and a simple preparation method.
Description
Technical field
The present invention relates to sealing ring material field, is exactly a kind of ethylene-propylene diene reclaimed rubber rubber unvulcanizate sealing-ring.
Background technology
Terpolymer EP rubber is the terpolymer of ethene, propylene and non-conjugated diene hydrocarbon, and its topmost characteristic is exactly its superior resistance to oxidation, anti-ozone and erosion-resistant ability.Because terpolymer EP rubber belongs to polyolefine family, it has fabulous vulcanization characteristics.In the middle of all rubber, EPDM has minimum proportion.It can absorb a large amount of fillers and oil and influencing characteristic is little.Therefore can the cheap rubber compound of cost of manufacture.
Styrene-butadiene rubber(SBR) (SBR) is maximum general purpose synthetic rubber kind, is also one of rubber of realizing the earliest suitability for industrialized production.It is divinyl and cinnamic random copolymers.Its physical mechanism performance, the use properties of processing characteristics and goods is close to natural rubber, some performance is as wear-resisting, heat-resisting, ageing-resistant and vulcanization rate is more good compared with natural rubber, can with natural rubber and various synthetic rubber use, be widely used in the fields such as production of tire, adhesive tape, sebific duct, electric wire, medical apparatus and various rubber items.
Summary of the invention
Object of the present invention provides a kind of good-extensibility, the ethylene-propylene diene reclaimed rubber rubber unvulcanizate sealing-ring that tensile strength is high.
Above-mentioned purpose realizes by following scheme:
An ethylene-propylene diene reclaimed rubber rubber unvulcanizate sealing-ring, is characterized in that:
It is to be made by the raw material of following weight parts:
Ethylene-propylene diene reclaimed rubber 65-70, cis-butadiene cement 35-40, styrene-butadiene rubber(SBR) 10-15, SULPHUR POWDER 1.5-2.5, semi-reinforcing carbon black 5-8, fatty acid modified calcium carbonate 2-5, white carbon black 2-4, nano barium sulfate 30-35, glycol ether 5-8, paraffin oil 10-15, microcrystalline wax 1-2, the different phenylpropyl alcohol 1-2 of peroxidation two, red precipitate 5-7, stearic acid 0.8-1.2, cashew nut shell oil 2-3, zinc borate 8-12, titanium dioxide 8-12, trioctyl trimellitate 4-8, white factice 7-9, accelerant CZ 0.8-1.2, altax 0.5-1, Vulcanization accelerator TMTD 0.3-0.7, anti-aging agent RD 0.8-1.2, antioxidant BLE 0.5-0.8.
Described a kind of ethylene-propylene diene reclaimed rubber rubber unvulcanizate sealing-ring, is characterized in that: its through banburying, open refining and post cure technique after preparation and obtain.
Described a kind of ethylene-propylene diene reclaimed rubber rubber unvulcanizate sealing-ring, is characterized in that: during preparation, first by Banbury mixer synthetic rubber, again synthetic rubber is opened after the type of being smelt by mill, after post cure, the rubber seal deburring by post cure, obtains again.
Beneficial effect of the present invention is:
Good-extensibility of the present invention, high temperature resistant low temperature performance excellent, tensile strength is high, and when using reclaimed rubber cost-saving, preparation method is simple.
