Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a preparation of a composite material with high protective properties based on TPV base material and its application in highly flexible soft cable products, which has the advantages of high strength and solves the problem of heat resistance and solvent resistance. On the one hand, it cannot meet the requirements of some industries. PP+EPDM blended dynamic vulcanized elastomer (TPV) has excellent heat resistance and solvent resistance, which makes up for the shortcomings of TPES materials, while traditional cables have poor flexibility. , so the service life is short and inconvenient to use

Abstract

The invention relates to the technical field of cables, and discloses preparation of a high-protection composite material based on a TPV base material. The preparation comprises the following steps: taking a plurality of maleic anhydride at the first; and adding the maleic anhydride into EPDM for grafting reaction to obtain EPDM-g-MA with a grafting rate of 1-3%, wherein the grafting reaction comprise steps of premixing EPDM, a free radical initiator and additives and then adding the mixture to an internal mixer. The preparation of the high-protection composite material based on the TPV base material and the application of the high-protection composite material in high-flexibility flexible cable products overcome a shortcoming of poor blending compatibility between the EPDM as a non-polarmaterial and strong polar nylon by grafting non-polar EPDM with maleic anhydride and then reacting with nylon to obtain modified EPDM, and improve blending processability and high strength of the TPVmaterial; and antioxidants, light stabilizers and internal lubricants are added to make the prepared TPV material have relatively long service life and processing stability.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to the preparation of a composite material with high protective properties based on TPV base material and its application in highly flexible soft cable products. Background technique [0002] TPV is mainly composed of two parts, one is plastic as the continuous phase, and the other is rubber as the dispersed phase. Usually rubber needs to be combined with softening oil or plasticizer. Vulcanizing agent and some auxiliary agents are also essential. In addition, for To reduce costs or improve certain aspects of performance, some inorganic fillers will be added. [0003] The application of thermoplastic elastomer TPE has gradually deepened and expanded. Although styrene-based TPE (TPEs) is widely used, this type of material cannot meet the requirements of some industries in terms of heat resistance and solvent resistance. PP+EPDM blended dynamic vulcanized elastomer (TPV) has excellent...
