Problems solved by technology

However, due to the vast geographical area of ​​our country and the large temperature difference between the north and the south, if the heat resistance of the cable is poor, it is easy to age and fall off. It also affects the construction work and is not conducive to the improvement of people's living standards.

Embodiment 1

[0013] This embodiment provides a polyvinyl chloride heat-resistant cable material, which consists of the following components in parts by weight: polyvinyl chloride resin 80-110; trioctyl trimellitate 30-40; lead stearate 0.7-1.2 ; Bisphenol A 0.2-0.8; Calcined pottery clay 2-7; Its preparation method comprises the steps:

[0014] (1) Preparation of slurry: mixing and grinding trioctyl trimellitate, lead stearate, bisphenol A and calcined clay to prepare slurry;

[0015] (2) The slurry obtained in the step is kneaded with polyvinyl chloride resin, refined by an open plastic refiner, and then entered into a pelletizer to form pellets, which can be obtained.

[0016] The trioctyl trimellitate can be used as a plasticizer; the lead stearate can be used as a stabilizer to make the product have good lubricity; adding bisphenol A can ensure that the inner core of the cable material is not easily corroded.

Embodiment 2

[0018] This embodiment provides a polyvinyl chloride heat-resistant cable material, which consists of the following components in parts by weight: polyvinyl chloride resin 80; trioctyl trimellitate 30; lead stearate 0.7; bisphenol A 0.2; Calcined pottery clay 2; its preparation method, comprises the steps:

[0019] (1) Preparation of slurry: mixing and grinding trioctyl trimellitate, lead stearate, bisphenol A and calcined clay to prepare slurry;

[0020] (2) The slurry obtained in the step is kneaded with polyvinyl chloride resin, refined by an open plastic refiner, and then entered into a pelletizer to form pellets, which can be obtained.

Embodiment 3

[0022] This embodiment provides a polyvinyl chloride heat-resistant cable material, which consists of the following components in parts by weight: polyvinyl chloride resin 110; trioctyl trimellitate 40; lead stearate 1.2; bisphenol A 0.8; Calcined pottery clay 7; its preparation method comprises the steps of:

[0023] (1) Preparation of slurry: mixing and grinding trioctyl trimellitate, lead stearate, bisphenol A and calcined clay to prepare slurry;

[0024] (2) The slurry obtained in the step is kneaded with polyvinyl chloride resin, refined by an open plastic refiner, and then entered into a pelletizer to form pellets, which can be obtained.

Abstract

The invention relates to a polyvinyl chloride heat-resistant cable material and a preparation method thereof. The cable material is prepared from, by weight, 80-110 parts of polyvinyl chloride resin,30-40 parts of trioctyl trimellitate, 0.7-1.2 parts of lead stearate, 0.2-0.8 part of bisphenol A and 2-7 parts of calcined clay. The cable material has the advantages of being resistant to wear, notlikely to be pressed flat, good in insulating property and the like. The cable material is good in heat resistance and not prone to ageing or falling off, occurrence of fire is avoided, and meanwhilenormal operation of outdoor construction for laying cables is facilitated.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a polyvinyl chloride heat-resistant cable material and a preparation method thereof. Background technique [0002] Plastics for wire and cable insulation and sheathing are commonly known as cable materials, including rubber, plastic, nylon and other varieties. Cable material production enterprises take cable production enterprises as users, as long as there is a demand for wire and cable, there will be a market for cable materials. Except for bare wire products such as steel-cored aluminum stranded wire and electromagnetic wire, almost all wire and cable products require an insulation layer. However, due to the vast geographical area of ​​our country and the large temperature difference between the north and the south, if the heat resistance of the cable is poor, it is easy to age and fall off. It also affects the construction work, which is not conducive ...
