Embodiment Construction

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

[0009] An ethanol-resistant fuel-fuel rubber composition, in parts by weight, containing nitrile rubber 60-70 with an acrylonitrile content of 40-50%, polyvinyl chloride 30-40, plasticizer 26-36, and stearic acid 1.5 -3.5, reinforcing filler 67-90, antioxidant 5-13.5.

[0010] As the aforementioned plasticizer, it is required that it does not chemically react with polyvinyl chloride, and has low volatility, compatibility, solvent resistance and non-migration. For example, dibutyl phthalate, followed by dioctyl phthalate, and the plasticizer is less than 67 parts by weight or more than 90 parts by weight, and the composition tends to not satisfy the performance. In parts by weight, dibutyl phthalate 18-24 and dioctyl phthalate 8-12 are preferred.

[0011] Properly increasing the amount of reinforcing filler can reduce swelling. Examples of the aforementioned reinforcing filler include c...

Abstract

The invention relates to the field of rubber combination, in particular discloses ethanol fuel oil resistance rubber. The rubber includes the components by weight: 60 to 70 parts of 40 to 50 percent acrylonitrile containing butadiene-acrylonitrile rubber, 30 to 40 parts of polyvinyl chloride, 26 to 36 parts of plasticiser, 1.5 to 3.5 parts of stearic acid, 67 to 90 parts of reinforcing filler and 5 to 13.5 parts of antiager, wherein, the plasticiser is at least one of dibutyl phthalate or dioctyl phthalate, the reinforcing filler is at least one of china clay, spraying carbon black, or carbon black, and the antiager is at least one of antiager NAPM, antiager MB, or antiager 4020. Rubber products produced by the technical scheme achieve the standard of ethanol fuel oil resistance HESD 3207-06 on vehicle rubber products of Japan Honda, and not only meet the requirement of the rubber products on normal performance, but also further solve the defect that the existing rubber products can not resist the ethanol fuel oil.

Description

【Technical Field】 [0001] The present invention relates to the field of rubber combination, in particular to a rubber composition resistant to ethanol fuel. 【Background technique】 [0002] The formula factors of rubber determine the performance of rubber. At present, the reasons why rubber products have poor resistance to ethanol and fuel are: 1. Low acrylonitrile content and poor swelling resistance; 2. High volatility of plasticizers, poor compatibility, and easy migration , The amount is small; 3. The amount of reinforcing agent is small; 4. The antioxidant effect is poor. These reasons cause the ethanol fuel to penetrate into the rubber molecular chain and cause swelling. With the development of new energy technologies, vehicle fuels are developing in the direction of "clean, environmentally friendly, and energy-saving", and ethanol fuels have begun to be widely used. Although the current automotive rubber has normal properties such as high temperature resistance and gasoline ...
