Embodiment 1

[0039] A method for preparing a 125°C-resistant halogen-free flame-retardant thermoplastic elastomer EV cable material, comprising the following steps:

[0040] 1) First pour the elastomer resin into the high-speed mixer, pour in the filler oil while stirring at high speed, and stir for 2 minutes;

[0041]2) After the oil filling is completed, add polyolefin resin, polyphenylene ether resin, acrylate rubber, flame retardant, crosslinking agent, auxiliary crosslinking agent and other additives, and discharge after stirring evenly;

[0042] 3) Put the uniformly mixed raw materials into a twin-screw extruder for melt kneading and extrude granulation (the main engine speed of the twin-screw extruder is 500r / min, and the extrusion temperature is 170°C), and finally a 125°C resistant Grade halogen-free high flame retardant thermoplastic elastomer wire and cable compound;

[0043] In this cable material, comprise the raw material of following weight part:

[0044] 15 parts of polyp...

Abstract

The invention discloses a halogen-free flame retardant thermoplastic elastomer EV cable material resistant to 125 DEG C and a preparation method thereof. The provided cable material has good oil resistance, and the provided method has the characteristics of convenience for production and low cost. A technical scheme is as below: the halogen-free flame retardant thermoplastic elastomer EV cable material resistant to 125 DEG C comprises polyolefin resin, an elastomer, polyphenyl ether resin and other auxiliary materials. The preparation method of the halogen-free flame retardant thermoplastic elastomer EV cable material resistant to 125 DEG C includes the following steps: 1) preparing raw materials in the following weight portions; 2) pouring the elastomer resin high into a high-speed mixing machine, and pouring filling oil during high speed stirring; 3) adding polyolefin resin, stirring at high speed and discharging; and 4) putting the evenly mixed material into a double-screw extruder, conducting melt kneading, extruding and granulating.

Description

technical field [0001] The invention relates to the field of thermoplastic polymer materials, in particular to a 125°C-resistant halogen-free high flame-retardant thermoplastic elastomer wire and cable material and a preparation method thereof. Background technique [0002] Thermoplastic Elastomer (Thermoplastic Elastomer), referred to as TPE, is known as the "third-generation synthetic rubber" because of its characteristics of both plastic and rubber. With the continuous improvement of human environmental protection awareness, the voice of restricting the use of PVC in foreign countries is increasing day by day, which also promotes the rapid growth of TPE consumption, so the application prospect of TPE is very promising. [0003] Nowadays, electric vehicle technology has become the focus technology for the automotive industry to deal with environmental pollution and alleviate the energy crisis. Various countries and major automakers around the world have invested heavily in...
