Problems solved by technology

[0002] Most of the existing sealing rings are made of rubber, which can have a good sealing effect. However, the traditional sealing rings cannot be used for a long time under the environment of -50°, and they cannot be used for a long time under the environment of 175° or above. , the high and low temperature performance is not beneficial enough, resulting in a reduction in the service life of the sealing ring, therefore, it is particularly important to solve this type of problem

Embodiment 1

[0010] This example provides a binary ethylene propylene rubber sealing ring formula with excellent high and low temperature performance, the formula includes: 100 parts of binary ethylene propylene rubber, 75 parts of N550 carbon black, 10 parts of high flash point paraffin oil, nano clay 20 parts, 8 parts of zinc oxide, 1 part of stearic acid, 2.5 parts of vulcanizing agent DCP, 10 parts of non-phthalic polyester plasticizer, 2 parts of anti-aging agent RD, 0.5 part of anti-heat spirit, a total of 229 parts.

Embodiment 2

[0012] This example provides a binary ethylene propylene rubber sealing ring formulation with excellent high and low temperature performance, the formulation includes: 80 parts of binary ethylene propylene rubber, 50 parts of N550 carbon black, 5 parts of high flash point paraffin oil, nano clay 10 parts, 4 parts of zinc oxide, 1 part of stearic acid, 2.5 parts of vulcanizing agent DCP, 5 parts of non-phthalic polyester plasticizer, 2 parts of anti-aging agent RD, 0.5 part of anti-heat spirit, a total of 160 parts.

Embodiment 3

[0014] This example provides a binary ethylene propylene rubber sealing ring formulation with excellent high and low temperature performance, the formulation includes: 90 parts of binary ethylene propylene rubber, 60 parts of N550 carbon black, 8 parts of high flash point paraffin oil, nano clay 15 parts, 6 parts of zinc oxide, 1 part of stearic acid, 2.5 parts of vulcanizing agent DCP, 8 parts of non-phthalic polyester plasticizer, 2 parts of anti-aging agent RD, 0.5 part of anti-heat spirit, a total of 193 parts.

[0015] The high and low temperature resistance of the sealing ring is improved by adding vulcanizing agent DCP and non-phthalic polyester plasticizer, so that the sealing ring can be used for a long time under the environment of -50° and above 175°, which greatly prolongs the sealing ring service life.

Abstract

The embodiment of the invention provides an ethylene-propylene monomer seal ring with excellent high / low-temperature properties. The seal ring is prepared from 80-100 parts of ethylene-propylene monomer, 50-75 parts of N550 carbon black, 5-10 parts of high-flash paraffin oil, 10-20 parts of nano argil, 4-8 parts of zinc oxide, 1 part of stearic acid, 2.5 parts of vulcanizing agent DCP (dicumyl peroxide), 5-10 parts of non-phthalate polyester plasticizer, 2 parts of anti-aging agent RD and 0.5 part of heat-resistant agent. The vulcanizing agent DCP and non-phthalate polyester plasticizer are added to enhance the high / low temperature resistance of the seal ring.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a formula of a binary ethylene propylene rubber sealing ring with excellent high and low temperature performance. Background technique [0002] Most of the existing sealing rings are made of rubber, which can have a good sealing effect. However, the traditional sealing rings cannot be used for a long time under the environment of -50°, and they cannot be used for a long time under the environment of 175° or above. , the high and low temperature performance is not beneficial enough, resulting in a reduction in the service life of the sealing ring, therefore, it is particularly important to solve this type of problem. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a binary ethylene propylene rubber sealing ring formula with excellent high and low temperature performance, and the high and low temperature resistance of ...
