Problems solved by technology

[0002] As the use of automobiles requires higher and higher performance, the performance requirements for auto parts are also increasing; on the one hand, rubber hoses for automobiles require materials to have oil resistance, and on the other hand, they are required to have anti-ozone properties to prevent them from being damaged during production and use. Cracks occurred after a period of time; later, by adding some polyvinyl chloride plastic to nitrile rubber, the ozone resistance performance was greatly improved, but the quality of the product could not keep up due to the poor fusion of plastic and rubber

[0021] Table 1 Raw material ratio (parts by weight)

[0022]

[0023]

[0024] The preparation method is as follows:

[0025] The first step: Weigh the raw materials according to the above weight percentage

[0026] Step 2: Use a rubber internal mixer to mix the rubber, active agent, anti-aging agent, and filler evenly between 80°C and 120°C.

[0027] Step 3: Use the second-stage rubber mixing to add the vulcanization accelerator on the open mill between 40°C and 60°C and mix evenly.

[0028] Step 4: Extrude at 70°C.

[0029] Step 5: vulcanization molding under the condition of 150°C×30 minutes.

[0030] Table 2 The nitrile rubber / chloroprene rubber blend material prepared by the above method, the main properties are as follows.

[0031]

[0032] The above experimental data proves that the present invention has certain quality stability, is suitable for processing oil-resistant oil pipes, and is also suitable for processing and manufacturing sealing strips.

Abstract

The invention provides an anti-cracking and anti-aging blend material for an oil pipe of an automobile. The blend material is obtained by blending most readily available materials such as nitrile rubber and chloroprene rubber, particularly the nitrile rubber, the chloroprene rubber, a vulcanizing agent, an accelerating agent, an active agent, an anti-aging agent, an antioxidant and a filler; and a finished product is obtained by performing rubber mixing, extrusion and vulcanization on an operating agent under a certain temperature environment. The blend material has the advantages of low cost, usability in the preparation of the oil pipe with comprehensive performance such as ozone resistance, oil resistance and the like, high material compatibility, uniform dispersion of a compounding agent, no island phase structure, easy processing, high anti-aging performance, high ozone resistance, excellent physical and mechanical performance such as hardness, intensity and the like, good extrusion manufacturability and vulcanization manufacturability, capability of prolonging the service life of the product and particular suitability for oil-resistance rubber pipe products.

Description

technical field [0001] The invention relates to parts of automobile oil pipes, in particular to a blend material used for anti-cracking and aging of automobile oil pipes. Background technique [0002] As the use of automobiles requires higher and higher performance, the performance requirements for auto parts are also increasing; on the one hand, rubber hoses for automobiles require materials to have oil resistance, and on the other hand, they are required to have anti-ozone properties to prevent them from being damaged during production and use. After a period of time, cracks occurred; later, by adding some polyvinyl chloride plastic to nitrile rubber, the ozone resistance was greatly improved, but the quality of the product could not keep up due to the poor fusion of plastic and rubber. Contents of the invention [0003] The object of the present invention is to provide a kind of blending material for anti-cracking and aging of automobile oil pipe which has excellent com...
