Embodiment 1-10

[0041] As shown in Table 1, the main difference of Examples 1-10 is that the ratio of raw materials is different.

Embodiment 1

[0043] In Example 1, the unsaturated vulcanizing agent is selected from vinyl dimethyl ethoxy silane, the initiator is selected from azobisisobutylamidine hydrochloride, the coupling agent is selected from isopropyl triisostearate titanate, powder The coal ash is Class II fly ash of class F.

[0044] The preparation method of the anti-bending rubber material for the data line of Example 1 is as follows:

[0045] (1) Weigh Portland cement and fly ash by weight, and mix and stir at 50°C for 17 minutes to obtain mixture 1, which is set aside;

[0046] (2) Weigh the EPDM emulsion and the coupling agent by weight, add the coupling agent and the mixture 1 into the EPDM emulsion, stir at 55° C. for 30 minutes to obtain the mixture 2, and set aside;

[0047] (3) Weighing the initiator and the unsaturated vulcanizing agent according to parts by weight, adding the initiator and the unsaturated vulcanizing agent into the mixture 2, and fully stirring at 55° C. to obtain the mixture 3; ...

Embodiment 11

[0053] The difference between this example and Example 10 is that the formula also contains 10kg of stabilizer, and the stabilizer is Wenlun glue.

Abstract

The application relates to the field of rubber processing, and specifically discloses a bending-resistant rubber material used for data lines and a preparation method thereof. The anti-bending rubber material used for the data line is made of the following components by weight: 100-125 parts of EPDM rubber emulsion, 40-55 parts of fly ash, 10-20 parts of Portland cement, unsaturated 2.1-2.35 parts of vulcanizing agent, 0.2-0.4 parts of initiator, 0.85-0.90 parts of coupling agent; the preparation method is: (1) mixing Portland cement and fly ash to obtain mixture 1; (2) mixing Add the coupling agent and mixture 1 to the EPDM emulsion, and stir to obtain mixture 2; (3) Add the initiator and unsaturated vulcanizing agent to mixture 2, and obtain mixture 3 after stirring; (4) Add mixture 3 to knead It is mixed in the equipment, and then vulcanized on a flat vulcanizing machine to obtain a bending-resistant rubber material. The product of the application helps to improve the compatibility of fly ash and EPDM rubber, and enhance the bending resistance of EPDM rubber.

Description

technical field [0001] The present application relates to the field of rubber materials, more specifically, it relates to a bending-resistant rubber material for data lines and a preparation method thereof. Background technique [0002] The data cable is a necessary component to connect two hardware devices. Generally, the copper foil wire is used as the core material. For the purpose of protecting the copper foil wire, when the data cable is produced, the copper foil wire is usually covered with a rubber protective layer. In the process of actually using the data line, the data line is prone to bending, and the rubber protective layer is prone to cracks due to concentrated force when bending occurs. In order to improve the bending resistance of the data cable, it is necessary to modify the rubber material used to produce the rubber protective sleeve. [0003] In the related art, the Chinese patent whose authorized notification number is CN103804803B discloses a use of fly ...
