Embodiment 1~ Embodiment 4
[0023] Embodiment 1~Example 4 and Comparative Example 1~Comparative Example 4
[0024] The polyamide is PA6, the glass fiber is alkali-free glass fiber whose surface has been treated with silane coupling agent, the antioxidant is hindered phenolic antioxidant, the lubricating and dispersing agent is silicone, and the compatibilizer is maleic anhydride, methyl Glycidyl acrylate bifunctional co-grafted polyolefin elastomer. Each raw material was weighed according to the weight percentage shown in Table 1.
[0025] The weight percent (wt%) of each raw material in the table 1 embodiment 1~embodiment 4 and comparative example 1~comparative example 4
[0026]
[0027] Except for the glass fiber, put other raw materials into a high-efficiency mixer and mix for 5 minutes, and then discharge; the obtained premix is extruded and granulated by a twin-screw extruder, and the glass fiber is fed sideways during the extrusion process. The feed port is added, the processing temperatur...
Embodiment 5
[0033] The glass fiber is alkali-free glass fiber whose surface has been treated with silane coupling agent, the antioxidant is hindered phenolic antioxidant, the lubricating and dispersing agent is silicone, the compatibilizer is maleic anhydride, glycidyl methacrylate bis Functional group co-grafted polyolefin elastomer. Take each raw material according to the following weight percentages:
[0034] Polyamide 62.5%, ABS 22%, compatibilizer 5%, glass fiber 10%, antioxidant 0.2%, lubricating dispersant 0.3%.
[0035] Except for glass fiber, put other raw materials into a high-efficiency mixer and mix for 4 minutes, and then discharge; the obtained premix is extruded and granulated by a twin-screw extruder, and the glass fiber is fed sideways during the extrusion process. The feed port is added, the processing temperature is 210-235°C, divided into nine sections, one section is 210°C, the second section is 215°C, the third section is 220°C, the fourth section is 225°C, the fi...
