Abstract

The invention belongs to the field of flame-retardant cables, and particularly relates to a preparation method of a radiation-preventive flame-retardant cable material. The preparation method includes following steps: (1), preparing a radiation-preventive agent; (2), activating the radiation-preventive agent; (3), preparing the cable material: mixing a flame retardant, the radiation-preventive agent after being activated, carbon nanotube, vinyl distearamide, glycerol triacetate, triazine ultraviolet absorbent, ethylene glycol dimethacrylate, polyolefin elastomer, triethylene diamine, initiator, antioxidant 1010 and high-density polyethylene, putting a mixture into a torque rheometer, blending at 100-125 DEG C and 100-150r / min for 25-35min, and performing extrusion molding to obtain the cable material. The cable material prepared by the method has high radiation-preventive performance, excellent mechanical performance, good flame-retardant effect and high market popularization value.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of flame-retardant cable materials, in particular to a preparation method of radiation-proof flame-retardant cable materials. [0003] 【Background technique】 [0004] Wire and cable are important equipment for electric power industry. In the process of industrial, agricultural and commercial development, the transmission of data by cables is inseparable. However, in the process of actual application of cables, due to the influence of external factors and the reasons of the cables themselves, the cables may catch fire. Once the cables happen Fire, it will spread along the cable to the surrounding flammable objects, and once the fire spreads, the fire speed will be very fast. The loss of personnel and equipment may also lead to environmental pollution. Therefore, the flame retardant and fireproof technology of wire and cable has become an important research topic in fire protection technology in recent years. ...
