Embodiment 1

[0017] An oil-resistant rubber consisting of the following components by weight fraction: natural rubber 60, neoprene rubber 40, acrylic rubber 10, silica 15, carbon black 20, zinc oxide 3, magnesium oxide 0.5, stearic acid 3, softening Agent 8, anti-aging agent 6, microcrystalline wax 2, pine tar oil 3, accelerator 1, binder 3, polyhexamethylene biguanide hydrochloride 2, butyl benzyl phthalate 2.

[0018] Described carbon black is carbon black N660.

[0019] The anti-aging agent is composed of anti-aging agent RD and anti-aging agent 3100.

[0020] The mass ratio of antioxidant RD to antioxidant 3100 is 1:2.

[0021] The softener is naphthenic oil.

[0022] The accelerator consists of accelerator TMTD and accelerator CZ, and the mass ratio of accelerator TMTD and accelerator CZ is 1:1.

[0023] The binder is a mixture of hydrocarbon resins.

[0024] The rubber produced by the above formula has an oil resistance (expansion rate after oil immersion) of 6%, a heat resistanc...

Abstract

The present invention relates to an oil-resistant rubber. The oil-resistant rubber of the present invention is added with natural rubber, which has the excellent performance of natural rubber. In addition, neoprene is added, and the rubber molecule contains chlorine atoms, which has excellent anti-oxidation and anti-ozone properties. Non-flammable, self-extinguishing after fire, oil resistance, solvent resistance, acid and alkali resistance, aging resistance, and good air tightness; acrylic rubber has good heat resistance and oil resistance, and can be used in lubricants containing sulfur, phosphorus, and chlorine additives. Stable performance, aging resistance, oxygen and ozone resistance, ultraviolet resistance and excellent air tightness. In addition, combined with other auxiliary components, the prepared oil-resistant rubber has good physical and mechanical properties, oil resistance less than 6%, good heat resistance and air tightness. It can fully adapt to the use of automobile oil cylinder seals.

Description

technical field [0001] The invention belongs to the technical field of rubber, and in particular relates to an oil-resistant rubber. Background technique [0002] With the development of the economy and the demand of climate, environment and other factors, the demand for rubber in the tire industry is also increasing, especially the rubber used in the oil cylinder seals used in automobiles has good oil resistance, heat resistance and air tightness of rubber. Certain requirements, the existing rubber often fails to meet the requirements, and its oil resistance can only reach 10%. [0003] How to improve the oil resistance of rubber is a technical problem to be solved in the present invention. Contents of the invention [0004] In order to solve the above technical problems, the present invention provides an oil-resistant rubber. The oil-resistant rubber of the present invention is added with natural rubber, which has the excellent properties of natural rubber. In addition...
