Abstract

The invention discloses a low temperature-resistant heat-resistant long-life PVC (Polyvinyl Chloride) wire cable material which is prepared from the following components: 100 weight parts of PVC, 45 to 55 weight parts of a plasticizer, 5 to 11 weight parts of a composite stabilizer, 3 to 5 weight parts of a composite flame retardant, 5 to 25 weight parts of additives, 0.5 to 0.8 weight part of a composite lubricating agent, 0.6 to 1.3 weight parts of auxiliary stabilizers and 1 to 2 weight parts of colour masterbatches; the low temperature-resistant heat-resistant long-life PVC wire cable material takes the PVC as a base material; N-C8-C10 alcohol tribenzoate and dioctyl sebacate are added into the base material, so that the mixture can bear the low temperature of -40 DEG C and the high temperature of 105 DEG C; the auxiliary stabilizers, such as a special calcium-zinc composite stabilizer, hydrotalcite and beta-diketone, are added and cooperate the plasticizer, so that the long-term aging performance of the formula can be ensured; kaolin and silicone are added to improve the insulating property of the PVC material, so that the discharge damage in a wire transmission process can beinhibited.

Description

technical field [0001] The invention relates to the technical field of automobile parts, in particular to a PVC automobile wire and cable material with low temperature resistance, heat resistance and long service life. Background technique [0002] At present, most of the domestic automobile wire and cable materials are ordinary cable materials. If the automobile wiring harness is overloaded for a long time, the temperature of the wire will exceed the maximum allowable temperature, which will accelerate the aging of the wire insulation, damage it, and cause a fire. During the operation of automobile wires, the insulation of the wires will be heated and the performance will gradually degrade until it fails. Automobile wires are prone to cracking when they are bent and used under extremely low temperature conditions. Electric wires should ensure that the insulating material has the required mechanical properties within the life of the vehicle, so there are higher requirements...
