Method for preparing insulating material with high-strength for cables

Abstract

The invention discloses a preparation method of an insulating material with high-strength cables, which comprises the following steps: heating and mixing acrylonitrile, acetonitrile, hydrocyanic acid and distilled water in an acrylonitrile mixed material; heating and mixing the butadiene mixed material at a temperature of 50 degrees Mixing between 70°C and styrene mixture at a temperature of 30°C to 60°C; heating and stirring the acrylonitrile mixed material and styrene mixed material, adding an initiator during the mixing process, and heating and mixing The butadiene blend is added to the blended acrylonitrile blend and styrene blend in the process. The cable insulation material contains polyester fiber. Polyester fiber has high temperature stability, low temperature crack resistance, fatigue resistance, and water stability. Polyester fiber can improve the toughness of the cable insulation material processed by ABS mixture and enhance the strength of the cable. Tensile resistance, improving the quality of the cable.

Description

Technical field [0001] The invention relates to the field of cables, in particular to a method for preparing insulating materials with high-strength cables. Background technique [0002] Cable is a general term for optical cables and cables. There are many uses for cables. They are mainly used for multiple functions such as controlling installation, connecting equipment, and transmitting power. It is a common and indispensable thing in daily life. Since cables are live, installation needs to be cautious. Definition of cable 1: It is made of one or more mutually insulated conductors and an outer insulating protective layer, which transmits electricity or information from one place to another; Definition 2: Usually consists of several or several groups of wires (At least two in each group) twisted rope-like cables, each group of wires are insulated from each other, and often twisted around a center, the whole outer bread has a high-insulation coating, the cable has power cables, ...

AI Technical Summary

Problems solved by technology

[0003] The main disadvantages of the cable: overload operation for a long time, the temperature of the cable will rise, the insulation will age, so that the insulation will be broken down and the construction quality will be reduced; the electrical aspects include: the construction technology of the cable head cannot meet the requirements, the sealing of the cable head is poor, Moisture invades the inside of the cable, and the insulation performance of the cable is reduced; when the cable is laid, no protective measures are taken, the protective layer is destroyed, and the insulation is reduced; in terms of civil engineering: the drainage of the well pipe trench is not smooth, and the cable is soaked in water for a long time, which damages the insulation strength of the work well If the cable is too small, the bending radius of the cable is not enough, and the damage caused by long-term extrusion and external force is mainly due to the brutal construction of machinery in municipal construction, digging and breaking the cable; the corrosion protection layer has been subjected to chemical corrosion or cable corrosion for a long time, resulting in the failure of the protection layer and the reduction of insulation; the cable itself Or the quality of the cable head accessories is poor, the sealing of the cable head is poor, the insulating glue is dissolved, and it is cracked, which leads to the resonance phenomenon of the station. Ferromagnetic resonance, the use of cables in some safety protection equipment and large outdoor machinery requires high cable performance, and the cables are required to be waterproof and tensile, especially in safety protection equipment. The damage of the cable causes a safety accident
