Embodiment Construction

[0008] The present invention will be further described below in conjunction with specific examples.

[0009] The present invention adopts EPDM rubber and methyl vinyl silicone rubber and chlorosulfonated polyethylene rubber to use together, selects the auxiliary vulcanization system that auxiliary crosslinking agent PDM and auxiliary crosslinking agent TAIC are used in combination, uses DCP as crosslinking agent, like this The rubber hose made not only improves the original high temperature resistance, corrosion resistance and fatigue resistance of EPDM rubber, but also greatly improves its air tightness, compression set and flame retardancy. is already in a leading position.

[0010] The polymer chain of EPDM rubber is fully saturated, so it has excellent heat resistance, ozone resistance, acid and alkali resistance, weather aging resistance, fatigue resistance, tear resistance and other properties, and is widely used in automobile manufacturing and construction industries ,...

Abstract

The invention relates to ethylene-propylene-diene rubber for a rubber tube system of a hydrogen energy powered automobile. The ethylene-propylene-diene rubber is characterized by comprising the following components by part by weight: 50-80 parts of ethylene-propylene-diene rubber, 10-25 parts of methyl vinyl silicone rubber, 10-25 parts of chlorosulfonated polyethylene rubber, 5-15 parts of bulking agent, 2-8 parts of zinc oxide, 1-7 parts of stearic acid, 1-5 parts of antiager RD, 1-5 parts of antiager MB, 40-90 parts of fast extruding furnace black N550, 10-30 parts of silica, 10-40 parts of paraffin based oil, 1-8 parts of cross-linking agent DCP, 1-8 parts of assistant crosslinker TAIC and 1-8 parts of assistant crosslinker PDM. The bulking agent is an ethylene-vinyl acetate copolymer. The ethylene-propylene-diene rubber provided by the invention completely conforms to technical standards, meets the performance requirements of products, excellently improves the airtightness, compression set and flame retardancy of an ethylene-propylene-diene rubber tube, and improves the high-temperature resistance, corrosion resistance and fatigue durability of the ethylene-propylene-diene rubber tube.

Description

technical field [0001] The invention relates to an EPDM rubber used in a rubber hose system of a hydrogen energy-powered vehicle, and belongs to the technical field of the rubber hose system of a hydrogen-energy powered vehicle. Background technique [0002] With the gradual formation of the "automobile society", the number of automobiles continues to rise, while resources such as oil are stretched. On the other hand, vehicles that swallow a large amount of gasoline continue to emit harmful gases and pollutants. The ultimate solution is of course not to limit the development of the automobile industry, but to open up new energy sources that can replace petroleum. New energy vehicles refer to all other energy vehicles except gasoline and diesel engines. Including fuel cell vehicles, hybrid vehicles, hydrogen energy vehicles and solar vehicles. [0003] Hydrogen energy-powered vehicles are a means of transportation that truly achieves zero emissions. The emissions are pure w...
