Example Embodiment
[0015] Example 1-2
[0016] Using PA6 slices with a viscosity of 2.8, alkali-free glass fibers for glass fibers, kaolin for inorganic minerals, and polyolefin elastomer grafted with maleic anhydride graft polymer CMG9805 as the compatibilizer of Example 1, the compatibility of Example 2 As the agent, EPDM rubber is grafted with maleic anhydride graft polymer CMG9802, the antioxidant is 1098 / 168 (1:1), and the coupling agent is KH550.
[0017] Ratio 1-2
[0018] raw material name Mixing ratio 1 (wt%) Mixing ratio 2 (wt%) PA6 slice 54 54 glass fiber 20 20 High territory 20 20 CMG9801 5 -- CMG9802 -- 5 1098 / 168(1∶1) 0.5 0.5 KH550 0.5 0.5
[0019] According to the conventional method, put the above-mentioned raw materials except glass fiber in a high-mixer and mix for 2-5 minutes, and then use a screw extruder together with the glass fiber to extrude and granulate. The processing temperature is 200-240℃, and the screw r...
