Abstract

The invention relates to an ethylene-propylene-diene monomer rubber seal ring, and belongs to the technical field of rubber preparation. The ethylene-propylene-diene monomer rubber seal ring comprises the following components in parts by weight: 100 to 195 parts of ethylene-propylene-diene monomer rubber, 1.2 parts of sulphur, 2.6 parts of accelerant, 3.5 parts of zinc oxide, 0.5 to 2 parts of stearic acid, 70 to 60 parts of carbon black, 75 parts of light calcium carbonate, 35 to 10 parts of naphthenic oil, 1 part of antiager, and 1 part of scorch retarder CTP (Cytidine Triphosphate). The ethylene-propylene-diene monomer rubber seal ring has the advantages that the components are simple, the raw materials are low in price and easy to obtain, the prepared ethylene-propylene-diene monomer rubber does not pollute a medium and environment, and the weather resistance, ozone resistance and heat resistance are obviously improved; in addition, the ethylene-propylene-diene monomer rubber seal ring is also good in electrical insulating property and high in resistance to corrosion of a chemical medium.

Description

technical field

[0001] The invention belongs to the technical field of rubber preparation, in particular to a EPDM sealing rubber ring. Background technique

[0002] The existing process for making rubber sealing rubber rings includes process steps such as mixing, extrusion, and vulcanization, wherein the rubber used in the mixing step is styrene-butadiene or natural rubber, and then combined with sulfur, accelerators, zinc oxide, Stearic acid, carbon black, light calcium, naphthenic oil, anti-aging agent and other auxiliary materials. The rubber sealing ring produced by this process has the following disadvantages: pollution to the medium and the environment, poor weather resistance, ozone resistance, and heat resistance, and lack of good electrical insulation and chemical medium corrosion resistance. Contents of the invention

[0003] The invention aims at the deficiencies in the prior art, and provides an EPDM sealing rubber ring which is green and environment-friendly...
