Embodiment 1

[0040] This example is used to illustrate the rubber composition and vulcanized rubber provided by the present invention.

[0041] The rubber composition A1 was mixed uniformly at a temperature of 35±5°C on a double-roller rubber mixer, and then the blend obtained by mixing was molded on a hydraulic plate vulcanizer at a temperature of 160°C and a pressure of 8 MPa for 30 minutes. Vulcanized rubber B1 was obtained. The rubber composition A1 contains ethylene-propylene rubber (the content of the ethylene structural unit in the ethylene-propylene rubber is 61% by weight, and the content of the third monomer is 5.5% by weight; the weight-average molecular weight of the ethylene-propylene rubber is 300,000, and the The third monomer is ENB) 100 parts by mass, nano active zinc oxide (average particle size is 30nm) 5 mass parts, stearic acid 1 mass part, carbon black 120 mass parts, paraffin oil 80 mass parts, nano active calcium carbonate ( The average particle size is 25nm) 60 pa...

Embodiment 2

[0044] This example is used to illustrate the rubber composition and vulcanized rubber provided by the present invention.

[0045] The rubber composition A2 was mixed uniformly at a temperature of 35±5°C on a double-roller rubber mixer, and then the blend obtained by mixing was molded on a hydraulic plate vulcanizer at a temperature of 150°C and a pressure of 10 MPa for 30 minutes. Vulcanized rubber B2 was obtained. The rubber composition A2 contains ethylene-propylene rubber (the content of the ethylene structural unit in the ethylene-propylene rubber is 61% by weight, and the content of the third monomer is 5.5% by weight; the weight-average molecular weight of the ethylene-propylene rubber is 200,000, and the The third monomer is ENB) 100 parts by mass, nano active zinc oxide (average particle size is 50nm) 5 mass parts, stearic acid 1 mass part, carbon black 120 mass parts, paraffin oil 80 mass parts, nano active calcium carbonate ( The average particle size is 10nm) 60 p...

Embodiment 3

[0048] This example is used to illustrate the rubber composition and vulcanized rubber provided by the present invention.

[0049] The rubber composition A3 was mixed uniformly at a temperature of 35±5°C on a double-roller rubber mixer, and then the blend obtained by mixing was molded on a hydraulic plate vulcanizer at a temperature of 140°C and a pressure of 5 MPa for 50 minutes. Vulcanized rubber B3 was obtained. The rubber composition A3 contains ethylene-propylene rubber (the content of the ethylene structural unit in the ethylene-propylene rubber is 70% by weight, and the content of the third monomer is 6% by weight; the weight-average molecular weight of the ethylene-propylene rubber is 400,000, and the The third monomer is ENB) 100 parts by mass, nano active zinc oxide (average particle size is 10nm) 10 mass parts, stearic acid 1 mass part, carbon black 200 mass parts, paraffin oil 150 mass parts, nano active calcium carbonate ( The average particle size is 40nm) 20 pa...

Abstract

The invention discloses a rubber composition. The rubber composition comprises ethylene propylene rubber, an activator, a reinforcing agent, a paraffin oil, a vulcanization accelerator, and a vulcanizing agent; the vulcanization accelerator is composed of 2-mercaptobenzothiazole, N-cyclohexyl-2-benzothiazole sulfonamide, diethyldiphenylthiuram disulfide, and tellurium diethyldithiocarbamate. The rubber composition contains no toxic raw material, possesses excellent physical properties, processing performance, and smell, and can be used for producing green passenger vehicle rubber sealing strips.

Description

technical field [0001] The present invention relates to a kind of rubber composition and vulcanized rubber and application thereof, particularly, relate to a kind of rubber composition containing non-toxic material, and the vulcanized rubber that this rubber composition makes, and this vulcanized rubber is used in passenger car sealing strip application. Background technique [0002] Passenger car sealing strip is one of the parts of passenger car. Now, the greening of passenger car sealing strips has begun to attract people's attention and attention. [0003] At present, most of the raw materials used to prepare passenger car rubber seals can still be used as raw materials for green passenger car rubber seals. For example, the third monomer is ENB type EPDM rubber, because of their high vulcanization speed, good extrusion process performance, excellent ozone resistance, weather aging resistance and relatively mature processing technology, especially It has good non-pollu...
