Abstract

The invention discloses a corrosion-resistant and high-temperature-resistant power cable material, which is characterized by being prepared from the following raw material components in parts by weight: 2-4 parts of phenol, 3-7 parts of magnesium nitride, 10-15 parts of titanium dioxide, 60-65 parts of polyvinyl chloride (PVC) resin, 5-8 parts of silicon carbide, 16-20 parts of dibasic lead phosphite, 8-12 parts of magnesium chloride, 3-5 parts of zinc borate, 12-15 parts of sodium thiocyanate, 2-4 parts of aluminum nitride and 1-3 parts of boron carbide. The corrosion-resistant and high-temperature-resistant power cable material has the advantages that the prepared material has good corrosion resistance, high temperature resistance, fire resistance, flame retardance, electrical insulatingperformance and processing property.

Description

Technical field [0001] The invention relates to the technical field of wires and cables, in particular to a corrosion-resistant and high-temperature-resistant power cable material. Background technique [0002] Wires and cables are used to transmit electrical (magnetic) energy, information, and realize the conversion of electromagnetic energy. Wires and cables in a broad sense are also referred to as cables, and cables in a narrow sense refer to insulated cables, which can be defined as: a collection of the following parts ; One or more insulated cores, as well as their respective possible coating layers, total protective layer and outer protective layer. [0003] In northern my country, the summer temperature is relatively high, the outdoor temperature is above 40 degrees, and the summer is a period of high electricity consumption. The existing cable will burn inside the cable under the long-term high temperature, which will affect the normal operation. Even worse, it will cause f...

Problems solved by technology

[0003] In the northern part of my country, the temperature is high in summer, and the outdoor temperature is above 40 degrees. Summer is also a period of high electricity consumption. Existing cables will burn inside the cable under long-term high temperature, which affects the normal operation. What's more, it will cause fire, so the performance of the cable material will directly endanger the lives of users and cause huge losses of property.

However, today's cable materials are generally poor in corrosion resistance, heat resistance and flame retardancy. Although some pay attention to the importance of corrosion resistance of cable materials, they ignore the changes in other properties while improving corrosion resistance. The overall effect of the cable is not obvious
