Problems solved by technology

[0003] Nitrile rubber (NBR) can only be used for a long time below 120°C, and its ozone resistance, weather resistance and radiation resistance cannot meet the sealing requirements of automobile engines; fluororubber has the best heat resistance and oil resistance, but its low temperature resistance is poor and The cost is also the highest; although acrylate rubber has high heat resistance, it has poor processability

Embodiment 1-3

[0028] A kind of hydrogenated acrylonitrile-butadiene rubber composition with high tearing, biodiesel resistance for automobile hose, its component is as table 1, is made by following preparation method, and step is as follows:

[0029] Step (1), pressurizing the hydrogenated nitrile rubber, zinc oxide, stearic acid and anti-aging agent under pressure of 0.25-0.35Mpa for 1min;

[0030] Step (2), then add high-clean carbon black SPHERON 5000A, thermal black N990, filler, plasticizer, and banbury at a pressure of 0.2-0.25Mpa for 3min;

[0031] Step (3), control the pressure at 0.2-0.25Mpa, raise the temperature to 90°C, add sulfur, vulcanizing agent, and accelerator, raise the temperature to 100°C, lift the top bolt on the internal mixer, and after the mixing rubber is turned over, mix it The top bolt on the machine is lifted and lowered, and when the temperature is raised to 125°C, the top bolt on the internal mixer is lifted, the rubber is discharged, cooled, and the strip is ...

Abstract

The invention discloses a high-tearing strength, biodiesel-resistant hydrogenated acrylonitrile butadiene rubber composition for automobile hoses, which is prepared from the following components in parts by weight: 100 parts of hydrogenated acrylonitrile butadiene rubber, 15 to 25 parts of highly clean carbon black, 90 to 120 parts of thermal decomposition process carbon black, 5 to 10 parts of filler, 20 to 30 parts of plasticizer, 5 to 8 parts of zinc oxide, 0.5 to 1.5 parts of stearic acid, 1 to 3 parts of anti-aging agent, 0.1 to 0.5 part of sulfur, 6 to 10 parts of vulcanizing agent and 3to 5 parts of accelerant. Since the rubber composition disclosed by the invention adopts hydrogenated acrylonitrile butadiene as a main material, on one hand, biodiesel corrosion can be effectively resisted, which is more favorable for the protection of safe fuel transportation, and on the other hand, the operating requirements of a high temperature-resistant, low-permeability fuel system can bemet.

Description

technical field [0001] The invention belongs to the technical field of rubber hoses, and relates to a hydrogenated nitrile rubber composition, in particular to a hydrogenated nitrile rubber composition with high tear resistance and biodiesel resistance for automobile hoses. Background technique [0002] With the depletion of fossil fuels and increasingly serious environmental pollution, leading to a global energy crisis, it is an inevitable trend to seek new alternative energy sources, and biodiesel has great potential for development. Biodiesel is a kind of diesel oil (liquid fuel) processed from biomass resources as the raw material. It has abundant sources and can be produced from raw materials such as vegetable oil and animal oil. It can be mixed with national standard diesel oil or used alone for automobiles and machinery, which can relieve the Reliance on traditional petroleum energy reduces environmental pressure. But it also puts forward strict requirements on the h...
