preparation Embodiment 1

[0033] Get 120 grams of formula I polymer, 10 grams of magnesium oxide; 2 grams of lead stearate; 10 grams of dioctyl sebacate; 30 grams of white carbon black; 5 grams of talc; 1 gram of stearic acid. First add other substances except talc powder into the high mixer at 120°C and mix for 10 minutes, then add the talc powder into the high mixer at 120°C and mix for 8 minutes. During the mixing process, the temperature is controlled at 120°C; The single-screw granulator is used for granulation, and the temperature of the single-screw granulator is controlled at 150°C; the granulated granules are cooled and dried, screened and magnetically separated, and finally measured and packaged. .

preparation Embodiment 2

[0035] Get 130 parts by weight of formula I polymer, 15 grams of magnesium oxide; 3 grams of lead stearate; 20 grams of dioctyl sebacate; 36 grams of white carbon black; 10 grams of talc; 2 grams of stearic acid. Prepare according to the method described in Example 1.

Abstract

The invention relates to a cold-resistant and flame-retardant cable including an inner conductor (1); the inner conductor (1) is externally provided with an isolation layer (2); the isolation layer (2) is externally provided with an insulating layer (3); an insulating layer (3) is externally provided with a protective sleeve (4), wherein the insulation layer (3) and the protective sleeve (4) are made of a polymer represented by the formula I. The cold-resistant and flame-retardant cable has excellent flame retardant performance and outstanding cold resistance.

Description

technical field [0001] The invention relates to the technical field of cables, more specifically, the invention relates to a cold-resistant and flame-retardant cable material. Background technique [0002] As the society pays more and more attention to fire hazards, the fire resistance of cables is also required to be higher. Some special flexible cables (such as elevator cables, telecommunication device cables, etc.) also require certain flame retardant performance, so it is necessary to develop PVC cold resistance fuel cable. In the prior art, PVC cold-resistant and flame-retardant cable materials are based on PVC resin, adding plasticizers (to reduce the processing temperature of the resin and reduce the softening point of the product), flame retardants (to improve the flame-retardant performance of the product), stabilizers ( Improve the heat resistance of the product, delay the degradation of PVC), lubricant (to improve the processing performance of the product, make t...
