The invention discloses a manufacturing method of silicon core pipes, including the following steps: selecting high-density polyethylene, sodium-based bentonite, linear dimethylsiloxane, nano boride, silicone oil, dimethyl silicone fluid, initiator and antioxidant as raw materials; mixing and reacting linear dimethylsiloxane and silicone to prepare olefin-modified silicone oil; grinding sodium-based bentonite and nano boride in a grinder; feeding the ground materials into a reaction kettle for reaction; extruding and granulating the reaction product via a twin-screw extruder; performing synchronous extrusion and compounding with high-density polyethylene and auxiliary agents; cooling and shaping; conducting metering printing, traction and winding to obtain finished products. This formula ensures full mixing and high compatibility of raw materials, achieving high overall consistency and composite strength of finished pipes. The product features improved corrosion resistance, aging resistance and greatly reduced friction coefficient through refined processing technology.
