Embodiment 1

[0013] The present embodiment 1 provides a kind of synthetic rubber, and its composition is as follows in parts by weight: 15 parts of natural rubber, 10 parts of EPDM rubber, 3 parts of phenol resin, 5 parts of titanate coupling agent, mineral 15 parts of oil, 5 parts of calcium oxide, 3 parts of magnesium hydroxide, 2 parts of carbon black, 1 part of anti-aging agent, 1 part of vulcanizing agent.

[0014] The titanate coupling agent can reinforce the filler modification, reduce the amount of rubber and anti-aging agent, improve the wear resistance and anti-aging ability of the product, and its gloss can also be significantly improved. In this embodiment, the titanate coupling agent is isopropyl titanate triisostearate. Isopropyl triisostearate titanate belongs to the monoalkoxy type of titanate coupling agent, and is a widely used titanate coupling agent. Of course, this selection is not a limitation, and other titanate coupling agents, such as monoalkoxypyrophosphate-based...

Embodiment 2

[0019] The second embodiment provides a kind of synthetic rubber. The composition is as follows in parts by weight: 25 parts of natural rubber, 17 parts of EPDM rubber, 7 parts of phenol resin, 10 parts of titanate coupling agent, mineral 25 parts of oil, 11 parts of calcium oxide, 7 parts of magnesium hydroxide, 6 parts of carbon black, 4 parts of anti-aging agent, 3 parts of vulcanizing agent.

[0020] In this embodiment, the titanate coupling agent is isopropyl titanate triisostearate. The anti-aging agent is a mixture of anti-aging agent MB and anti-aging agent 124, and the mass ratio of the two is 1:1. Anti-aging agent MB and anti-aging agent 124 are mixed, and the anti-aging effect is better. The vulcanizing agent is sulfur chloride.

Embodiment 3

[0022] The present embodiment 3 provides a kind of synthetic rubber, and its composition is as follows in parts by weight: 19 parts of natural rubber, 13 parts of EPDM rubber, 5 parts of phenol resin, 7 parts of titanate coupling agent, mineral 17 parts of oil, 8 parts of calcium oxide, 5 parts of magnesium hydroxide, 5 parts of carbon black, 2 parts of anti-aging agent, 2 parts of vulcanizing agent.

[0023] In this embodiment, the titanate coupling agent is isopropyl titanate triisostearate, the anti-aging agent is anti-aging agent 124, the vulcanizing agent is sulfur and sulfur chloride, and the mass ratio of sulfur to sulfur chloride is 2 :1.

Abstract

The present invention provides a synthetic rubber, and relates to the field of rubbers. The synthetic rubber comprises, by weight, 15-25 parts of natural rubber, 10-17 parts of an ethylene propylene diene monomer, 3-7 parts of a phenol resin, 5-10 parts of a titanate coupling agent, 15-25 parts of mineral oil, 5-11 parts of calcium oxide, 3-7 parts of magnesium hydroxide, 2-6 parts of carbon black, 1-4 parts of an anti-aging agent, and 1-3 parts of a vulcanizing agent. According to the present invention, the synthetic rubber has characteristics of good compression deformation performance, good wear resistance, and high practicality.

Description

technical field [0001] The invention relates to the field of rubber, in particular to a synthetic rubber. Background technique [0002] Rubber is an elastic polymer that is divided into synthetic rubber and natural rubber. Natural rubber is mainly derived from the latex of the Hevea trilobata tree, which is obtained through coagulation, washing, molding, and drying; synthetic rubber is made by artificial synthesis. At present, the output of synthetic rubber has far exceeded that of natural rubber. Synthetic rubber is often used in the chemical and mechanical industries, and in these industries, especially the mechanical industry, there are high requirements for the compression deformation and wear resistance of rubber, but the current synthetic rubber is difficult to meet the needs of the industry. Contents of the invention [0003] In view of this, the present invention provides a synthetic rubber to improve the problem of poor compression deformation and wear resistance...
