[0002] The high-efficiency flame retardant premixing device for low-smoke halogen-free cable materials is an automated mixing equipment specifically designed for the production of low-smoke halogen-free flame retardant cable materials. Its core function is to accurately measure a high proportion of high-efficiency powder flame retardants, such as metal hydroxides, before the cable material base resin enters the extrusion granulation host, and then use a high-speed, high-pressure mixer to fully and uniformly mix it with the base resin powder and a small amount of other additives, such as processing aids and coupling agents, to form a uniform premix, thereby ensuring that the flame retardant can be more stably and efficiently dispersed in the subsequent melt extrusion granulation process.

[0003] However, in existing premixing devices, the high-efficiency flame retardant component is highly hygroscopic and tends to slightly adhere to the hopper wall during mixing, affecting the mixing effect. Therefore, those skilled in the art have provided a premixing device for high-efficiency flame retardants in low-smoke halogen-free cable materials to solve the problems mentioned in the background art.
