preparation example Construction

[0025] The preparation process of thermoplastic cable sheathing material comprises the following steps:

[0026] S1. Premix

[0027] First add SEBS thermoplastic rubber, thermoplastic elastomer, photocurable cross-linking monomer, oligomer and calcium carbonate filler into the stirring pot and stir, then add softening oil and antioxidant into the stirring pot, stir and mix evenly;

[0028] S2. Extrusion granulation

[0029] Add the uniformly stirred and mixed material in step S1 into the hopper of the granulator, and heat the material in the hopper to a molten state at a heating temperature of 195-205°C, and transport the molten material to the die of the granulator. And cool the molten material in the die to obtain a material shape similar to the shape of the die, and then transport the shaped material to the cutting machine to obtain granular materials, that is, to obtain thermoplastic rubber substrates;

[0030] S3. Remix

[0031] Add the granular thermoplastic rubber su...

Description

technical field [0001] The invention belongs to the technical field of cable sheathing materials, in particular to a thermoplastic cable sheathing material and a preparation process thereof. Background technique [0002] Wires and cables are used to transmit electric (magnetic) energy, information and wire products that realize the conversion of electromagnetic energy. In a broad sense, wires and cables are also referred to as cables for short. In a narrow sense, cables refer to insulated cables, which can be defined as: a collection composed of the following parts ; One or more insulated wire cores, and their respective possible covering layers, total protective layer and outer sheath, and the cable may also have additional uninsulated conductors. Wire products used to transmit electric (magnetic) energy, information and realize electromagnetic energy conversion. In the broad sense, wires and cables are also referred to as cables, and in the narrow sense, cables refer to i...
