Embodiment 1
[0035] Embodiment 1: Preparation of high friction coefficient polyamide material
[0036] Raw materials: see Table 1
[0037] Preparation method: Add PA6 resin, coated inorganic filler, toughening agent, antioxidant and lubricant into a high-speed mixer for stirring
[0038] The mixture obtained above is granulated through a co-rotating intermeshing twin-screw extruder to prepare a polyamide material with a high coefficient of friction.
[0039] The obtained polyamide material with high friction coefficient was injection molded into a flat plate, and the basic mechanical properties were measured by proofing. The static friction coefficient test was carried out according to the ISO8295 standard, as shown in Table 1.
