Description

technical field [0001] The invention relates to the technical field of cable sheaths, in particular to a high wear-resistant and high-temperature resistant cable sheath material. Background technique [0002] With the rapid development of the cable field, the traditional rubber sheath material for cables can no longer meet the requirements of use. Due to its high temperature resistance, chemical corrosion resistance and low cost, phenolic resin is widely used in many fields such as cables, automobiles, transportation, military, etc. Fields, especially in the field of cables, in recent years, with the improvement of human fire prevention awareness and the urgent demand for flame retardant materials, various modified phenolic resins have been developed rapidly. [0003] Due to its large aspect ratio, carbon nanotubes are the thinnest fiber materials known so far. They have excellent mechanical properties, unique electrical properties, and good high temperature resistance. If t...

[0003] Due to its large aspect ratio, carbon nanotubes are the thinnest fiber materials known so far. They have excellent mechanical properties, unique electrical properties, and good high temperature resistance. If this carbon nanotube Tube-modified phenolic resin is made of high-temperature-resistant composite materials. Due to the scale effect of carbon nanotubes, large specific surface area and strong interfacial interaction, the heat generated can be exported through carbon nanotubes at high temperatures, thereby reducing The temperature of the product makes the performance of the phenolic resin / carbon nanotube composite material better than the physical and chemical properties of the same component conventional composite material, but the end of the carbon nanotube in the phenolic resin / carbon nanotube composite material is a region that is easy to undergo chemical reactions , leading to poor product stability and short service life, and with the increase of its content in rubber, this shortcoming is more obvious, resulting in poor product stability and long service life
