Problems solved by technology

[0009] However, since the peroxide vulcanization system is used in this prior art, the tearing performance of the product rubber hose is very poor, and it is also easy to bend or tear when preparing a small curvature air filter tube. , so the pass rate of the product is very low, and it is not suitable for industrial production

Embodiment 1-2

[0052] According to the ratio of raw materials shown in Table 1 below, the weight of the raw materials in grams was weighed to obtain the EPDM rubber formulations described in Examples 1-2 and Comparative Examples 1-4.

[0053] Table 1 embodiment 1-2 and comparative example 1-4 EPDM formula (unit gram)

[0054]

[0055]

[0056] In the EPDM rubber formula shown in the above-mentioned Examples 1-2 and Comparative Examples 1-4, the vulcanizing agent (peroxide 14-40B / sulfur) and the vulcanization accelerator (TAC, TMTD-80, After the other components except DPTT, DTDM and BZ) are mixed separately, the first stage of mixing is carried out in the internal mixer. After the mixed rubber obtained after the first stage of mixing is cooled at room temperature, a vulcanizing agent and a vulcanization accelerator will be added to the mixed rubber; Under the temperature of ℃, the EPDM rubber material was obtained, and its performance was tested.

[0057] Weigh an appropriate amount ...

Abstract

The invention provides an EPDM composition as well as a preparation method of an EPDM composite material air filter pipe. In the EPDM composition, EPDM and POE are used as raw material rubber components, and by adding the POE, the thermal tearing property and thermal deformation property of the prepared rubber material can be further improved. Meanwhile, in the preparation of the air filter pipe, by adopting a sulfur vulcanizing system, micro high-molecular chains in the prepared rubber pipe can be cross-linked, and the tearing property of the rubber pipe is better.

Description

technical field [0001] The invention of the present application relates to the field of rubber composition and rubber tube preparation, in particular, it relates to a preparation method of an EPDM composition and a rubber air filter tube; in particular, the invention of the present application relates to an automobile air filter A method for preparing a hollow filter tube. Background technique [0002] The car air filter is located in the car engine intake system, which is an assembly composed of one or more clean air air filter components connected to each other. The main function of the automobile air filter is to remove harmful impurities in the air entering the automobile cylinder by filtering, thereby reducing the early wear and tear of the automobile cylinder, piston, piston ring, valve and valve seat. [0003] The air filter tube is an important part of the car air filter. The car air filter can be connected with the engine and other components through the air filter...
