▎ 摘　　要

NOVELTY - A composite material comprises 1-10 pts. wt. conductive powder, 4-18 pts. wt. carbon powder, 100-150 pts. wt. polyethylene, 0.5-3 pts. wt. coupling agent, and 0.5-6 pts. wt. adhesive. The polyethylene has a single molecular weight of 140000-300000. USE - Composite material is used for producing stylus conductive pen point (all claimed). ADVANTAGE - The composite material comprises the polyethylene as a main material, which has stable chemical properties, good weather resistance, aging resistance and wear resistance, and excellent processing characteristics, facilitates the control of production parameters in the production process, and improves productivity. The polyethylene is a spatially conjugated structure, and can effectively improve the conductivity of the pen tip and improve writing sensitivity by further combining with the conductive powder. The composite material has high internal porosity and uniform pore size distribution after molding, and can reduce the overall weight of the nib material and absorb sound and shock, and has appropriate hardness which effectively reduces the impact sound of the screen when writing to achieve a better writing experience. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the stylus conductive pen point, which involves weighing the conductive powder, carbon powder, polyethylene, coupling agent, and binder, adding the conductive powder, carbon powder, polyethylene, and coupling agent to a mixer, adding the binder for several times while stirring and mixing at room temperature, mixing well and placing aside, filling the mixture into a nib mold cavity of a preset shape, pressurizing, heating, exhausting, pressure-hold molding, cooling to room temperature, demolding, and trimming.
