Embodiment 1

[0011] Embodiment 1 Preparation of cold-resistant sheathing material for cables of the present invention

[0012] Weigh 60 kg of PVC, 30 kg of chlorosulfonated polyethylene, 10 kg of 4-methoxy-1,3-phthalic acid bis(4-chlorophenyl) ester, 8 kg of dilauryl thiodipropionate, phosphoric acid 10 kg of tricresyl ester, 15 kg of N,N'-m-phenylene bismaleimide, 20 kg of carbon black, 8 kg of γ-chloropropyl-trimethoxysilane;

[0013] Place PVC and chlorosulfonated polyethylene in a drying oven to dry for 2 hours, seal and cool to room temperature, take out, add to a high-speed internal mixer preheated to 110°C, and stir and mix at a speed of 600 rpm for 5 minutes , add carbon black and tricresyl phosphate, stir at 1000 rpm for 15 minutes, then put the material into a cold mixer, and stir at 200 rpm until the material is cooled to room temperature;

[0014] Send the material to a two-roll mill, add dioctyl terephthalate, dilauryl thiodipropionate, N,N'-m-phenylene bismaleimide and γ-chl...

Embodiment 2

[0015] Embodiment 2 Preparation of cold-resistant sheathing material for cables of the present invention

[0016] Prepared according to the same process as in Example 1, the difference is that the parts by weight of each reagent are different, specifically: 80 kg of PVC, 40 kg of chlorosulfonated polyethylene, 4-methoxy-1,3-phthalic acid di (4-chlorophenyl) ester 20 kg, dilauryl thiodipropionate 5 kg, tricresyl phosphate 12 kg, N,N'-m-phenylene bismaleimide 10 kg, carbon black 30 kg 10 kg of γ-chloropropyl-trimethoxysilane.

Embodiment 3

[0017] The preparation of embodiment 3 comparative example cable sheath material

[0018] The comparative cable sheath material was prepared according to the same process as in Example 1, except that dioctyl terephthalate was used as a plasticizer.

Abstract

The invention relates to a cold-resistant plasticizer for cables. The cold-resistant plasticizer comprises 4-methoxy-1, 3-phthalic acid di-(4-chlorphenyl) ester. The cold-resistant plasticizer for the cables has the advantages that the cold-resistant plasticizer is excellent in cold-resistant, flame-retardant and aging-resistant characteristics and is quite suitable to be used in the fields of factories and mines, engineering, harbors and the like in low-temperature operation environments, and the like.

Description

technical field [0001] The invention relates to the field of power cables, in particular to a cold-resistant plasticizer for cables. Background technique [0002] With the development of the economy and the improvement of people's living standards, the demand for wires and cables is increasing day by day, and they play an important role in communication technology, radio and television, railway transportation, petrochemical, construction and other fields. Most of the wires and cables are made of PVC (polyvinyl chloride) plastic outer sheath. As the temperature decreases, PCV plastics have poor climate adaptability and will become harder and more brittle. If the construction is below 0 degrees, the cable is bent too fast or subjected to violent impact, the PVC plastic of the power cable will be broken due to brittleness and hardness. In northern China, especially in the northeast, the temperature in winter will drop to tens of degrees below zero. In this case, the general ...
