Abstract

The invention discloses high temperature resistant ethylene propylene rubber which consists of the following components in parts by weight: 10-30 parts of ethylene-propylene rubber, 10-20 parts of ethylene-propylene-diene monomer, 3-6 parts of a vulcanizing agent, 5-8 parts of toluene diisocyanate, 6-10 parts of calcium octoate, 10-12 parts of acetylene black, 3-5 parts of trisodium phosphate and 2-4 parts of aromatic hydrocarbon oil. The ethylene-propylene rubber and ethylene-propylene-diene monomer are both adopted, co-vulcanization of the ethylene-propylene rubber and ethylene-propylene-diene monomer is realized by adjusting the vulcanization system, and the requirement on high temperature resistance can be met; moreover, the sizing material obtains relatively low compression set, and the vulcanized product has good heat resistance, chemical stability and low compressive deformation; and by adopting white carbon black and phenolic resin, the processing fluidity of the sizing material is improved.

Description

A kind of resistant to elevated temperatures ethylene-propylene rubber(EPR)
Technical field
The present invention relates to technical field of rubber material, particularly relate to a kind of resistant to elevated temperatures ethylene-propylene rubber(EPR).
Background technology
Along with the development of rubber industry, the working conditions of rubber item is day by day harsh, has higher requirement to heat-resisting, and the rubber items such as a lot of rubber hose, sealing member require high temperature resistant 150 DEG C for a long time.Ethylene-propylene rubber(EPR) has outstanding heat-resisting, resistance to superheated vapour, the performances such as resistance to ozone, the Hou Laohua of resistance to sky and high insulation, especially heat aging property is good, but the general heatproof of conventional vulcanization ethylene-propylene rubber(EPR) can reach 125 DEG C, when temperature reaches 150 DEG C, the compression set of rubber item increases thereupon, to such an extent as to cisco unity malfunction, make it in long term high temperature use procedure, occur quality problems.
Summary of the invention
For the deficiency that prior art exists, technical problem to be solved by this invention is, provides a kind of machinery, good physical performance, can meet the resistant to elevated temperatures ethylene-propylene rubber(EPR) that goods are high temperature resistant to elastomeric material, low pressure becomes the requirement of condition very well.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of resistant to elevated temperatures ethylene-propylene rubber(EPR), is grouped into by the one-tenth of following weight part:
Ethylene propylene rubber 10 ~ 30;
Terpolymer EP rubber 10 ~ 20;
Vulcanizing agent 3 ~ 6;
Toluene di-iso-cyanide ester 5 ~ 8;
Calcium octoate 6 ~ 10;
Shawinigan black 10 ~ 12;
Tertiary sodium phosphate 3 ~ 5;
Aromatic hydrocarbon oil 2 ~ 4.
The advantage of the resistant to elevated temperatures ethylene-propylene rubber(EPR) of the present invention is: adopt ethylene propylene rubber and terpolymer EP rubber and use, making ethylene propylene rubber and terpolymer EP rubber covulcanization, can reach resistant to elevated temperatures requirement, and sizing material obtaining by adjusting vulcanization system
Lower compression set, vulcanizate has good thermotolerance, chemical stability and low compression set, adopts white carbon black and resol, improves the processing fluidity of sizing material.
Embodiment
Below in conjunction with specific embodiment, the present invention is described in further details;
A kind of resistant to elevated temperatures ethylene-propylene rubber(EPR), is grouped into by the one-tenth of following weight part:
Ethylene propylene rubber 10 ~ 30;
Terpolymer EP rubber 10 ~ 20;
Vulcanizing agent 3 ~ 6;
Toluene di-iso-cyanide ester 5 ~ 8;
Calcium octoate 6 ~ 10;
Shawinigan black 10 ~ 12;
Tertiary sodium phosphate 3 ~ 5;
Aromatic hydrocarbon oil 2 ~ 4.
Certainly, above-mentioned explanation is not limitation of the present invention, and the present invention is also not limited to above-mentioned citing; those skilled in the art; in essential scope of the present invention, the change made, remodeling, interpolation or replacement, all should belong to protection scope of the present invention.
