Embodiment 1～2
[0034] Examples 1-2: Using TPU elastomer resin as the basic material, a flame-retardant, high-temperature, oil-resistant, and oil-resistant flexible cable composite material was prepared by adding composite flame retardants, smoke suppressants, lubricants, antioxidants, and high-temperature-resistant fillers . From the test results of Examples 1-2 in Table 3, it is found that the comprehensive performance of the halogen-free flame-retardant and high-temperature-resistant cable composite material is very excellent.

The invention discloses a flame-retardant, high-temperature-resistant and oil-resistant flexible cable composite material and a preparation method thereof. According to the composite material, thermoplastic polyurethane is adopted as a basic material, a flame retardant, a smoke suppressant, an antioxidant, a lubricant and a high-temperature-resistant filler are added, melt blending is conducted through an internal mixer at the temperature of 200 DEG C, extrusion granulation is conducted through a single-screw extruder at the temperature of 180 DEG C, and the halogen-free, flame-retardant high-temperature-resistant and oil-resistant flexible composite material for cables is prepared. The composite material has the characteristics of no halogen, flame retardance, smoke suppression, high temperature resistance, oil resistance, flexibility, easiness in bending, convenience in processing, capability of being recycled and the like, and can be used as a sheath material of a halogen-free flame-retardant cable.
Description
technical field [0001] The invention relates to a flame-retardant, high-temperature, oil-resistant, and flexible cable composite material and a preparation method thereof, belonging to the field of modification of polymer-based composite materials. Background technique [0002] In recent years, with the rapid development of my country's electric power industry, the requirements for the insulation and sheath materials of cables are also increasing. Thermoplastic polyurethane resin materials have the advantages of softness, wear resistance, oil resistance and recyclability, and can be used as insulation and sheath layers of cables. However, polyurethane materials are very flammable and release a lot of smoke when burned. For occasions with flame retardant requirements and higher temperature resistance levels, they must be modified before use. Therefore, the development of a halogen-free flame-retardant, oil-resistant, and high-temperature-resistant flexible polyurethane cable...
