The cable mainly consists of the inner cable core and the sheath covering the cable core. The sheath plays the role of insulation and protection. However, the sheaths currently used in the market are generally made of plastic directly. For communication cables This kind of cable with relatively high requirements makes the common cable sheath material affect the communication data.

Embodiment 1
[0014] Weigh the following raw materials: linear low density polyethylene 80-90kg, carbon black masterbatch 10-14kg, benzoyl peroxide 8-10kg, stearic acid 8-10kg, decabromodiphenyl ether 15-25kg, Phosphate ester 15-25kg, silicone oil 3-5kg, dilauryl thiodipropionate 4-6kg.
[0015] The preparation method is as follows:
[0016] a. Select a sand mill to grind the carbon black masterbatch in the raw material into powder, then put it into the plastic mixer, add linear low density polyethylene, carbon black masterbatch, benzoyl peroxide, stearic acid , decabromodiphenyl ether and phosphite for mastication, and the temperature is controlled at 130-140°C;
[0017] b. After the mastication in step a is completed, add the original silicone oil and dilauryl thiodipropionate into it, stir evenly, and extrude to obtain granules.

Abstract
The invention relates to a communication cable special-purposed cable sheath material, and relates to the technical field of cable processing. The material is prepared from the raw materials of, by weight, 80-90 parts of linear low-density polyethylene, 10-14 parts of carbon black masterbatch, 8-10 parts of benzoyl peroxide, 8-10 parts of stearic acid, 15-25 parts of decabromodiphenyl ether, 15-25 parts of phosphite, 3-5 parts of a lubricant, and 4-6 parts of an antioxidant. The process flow is simple; raw material formulation is reasonable; and a sheath raw material is provided for communication cables. The material has the advantages of high insulation performance, high resistivity, low dielectric loss, strong signal transmission performance, and better application effect. With the material, communication cable reasonable application is ensured.
Description
technical field [0001] The invention relates to the technical field of cable processing, in particular to a special cable sheathing material for communication cables and a preparation method thereof. Background technique [0002] The wire and cable industry is the second largest industry in China after the automobile industry, and the product variety satisfaction rate and domestic market share both exceed 90%. Worldwide, China's wire and cable output has surpassed that of the United States, becoming the world's largest producer of wire and cable. With the rapid development of China's wire and cable industry, the number of new enterprises has been increasing, and the overall technical level of the industry has been greatly improved. The continuous and rapid growth of China's economy has provided a huge market space for cable products. The strong temptation of the Chinese market has made the world focus on the Chinese market. In just a few decades of reform and opening up, Ch...
