Problems solved by technology
[0002] The existing power cord material is composed of PVC resin and various plasticizers, stabilizers, lubricants and flame retardants. The material will release toxic and harmful substances as the temperature rises during processing. Most of the additives, stabilizers, and lubricants contain harmful substances such as lead and mercury, which are also poisonous and harmful to people's health. Moreover, this material is flammable, smokey, pollutes the environment, and causes harm to people's health.

Embodiment Construction
[0009] A method for manufacturing a flame-retardant low-smoke power cord material of the present invention comprises the following steps:
[0010] ①. Dry the nitrogen-phosphorus composite flame retardant at 95°C to make the water content less than 0.2%, and then put it into the high-speed mixer at a ratio of 100:1.5 by weight with the coupling agent for coupling at 110°C to obtain modified nitrogen Phosphorus composite flame retardant;
[0011] ② Put 29 parts of modified nitrogen-phosphorus composite flame retardant, 62 parts of polyolefin resin, 1 part of dispersant, 1.5 parts of lubricant and 0.4 part of antioxidant into the high-speed mixer and mix;
[0012] ③. The mixture obtained in step ② is heated in sections in an extruder, extruded into strips, cooled and cut into pellets.
