Embodiment 1
[0025] The core body of the odorless flame-retardant automobile wiring harness with a shock-absorbing structure in this embodiment is mainly composed of polypropylene resin (polymerization degree: 1600), and adipic acid plasticizer, carbon dioxide-based polymer, nano-silica, Calcium-zinc composite stabilizer, low-density polyethylene resin, stepless flame retardant and antioxidant, respectively by weight:
[0026]
[0027] Nano-silica is active fumed nano-silica with a density of 0.1-0.2g / cm 3 .
[0028] In this embodiment, the preparation process of the core body of the odorless flame-retardant automobile wiring harness with a shock-absorbing structure is as follows: 50 parts of polypropylene resin-1600, 3 parts of nano-silicon dioxide, 4 parts of calcium-zinc composite stabilizer, 17 parts Low-density polyethylene resin, 3 parts of inorganic flame retardant and 0.2 parts of antioxidant are mixed at 150±10°C with low-speed stirring, then the temperature is raised to 180°C...
Embodiment 2
[0031] The odorless and flame-retardant automobile wiring harness with shock-absorbing structure in this embodiment is mainly composed of polypropylene resin (polymerization degree: 1600), and adipic acid plasticizer, carbon dioxide-based polymer, nano-silica, calcium-zinc composite Stabilizer, low-density polyethylene resin, stepless flame retardant and antioxidant, by weight parts are respectively:

[0033] Nano-silica is active fumed nano-silica with a density of 0.1-0.2g / cm 3 .
[0034] In this embodiment, the preparation process of the core body of the odorless flame-retardant automobile wiring harness with a shock-absorbing structure is as follows: 58 parts of polypropylene resin-2000, 6 parts of nano-silica, 5 parts of calcium-zinc composite stabilizer, 18 parts Low-density polyethylene resin, 5 parts of inorganic flame retardant, 0.4 parts of antioxidant, 2.5 parts of barium sulfate and 1.7 parts of silicone powder were mixed at 150±10°C and stirred at a l...
Embodiment 3
[0037] See figure 1 , an odorless and flame-retardant automotive wiring harness with a shock-absorbing structure shown in an embodiment of the present invention. The automotive wiring harness includes a core body 1 and a tube body 2 sleeved outside the core body 1. The tube body 2 extends from the inside to the A heat equalizing layer 21, a buffer layer 22 and a heat dissipation layer 23 are provided in sequence on the outside, the heat equalizing layer 21 is made of a heat conducting material, one side of the heat equalizing layer 21 is close to the core body, and the other side is provided with bumps Structure 211. In this embodiment, the buffer layer 22 and the heat equalizing layer 21 are bonded by thermally conductive adhesive. The heat dissipation layer 23 is provided with a plurality of fins 231 on the surface in contact with the outside, so as to dissipate the heat of the core 1 to the outside.
[0038] To sum up: the core body of the odorless and flame-retardant aut...
