preparation example Construction
[0032] The preparation method of the high glass mineral fiber content high gloss polyamide material provided by the invention comprises the following steps:
[0033] S1. Mixing: uniformly pre-mix the hydrogen bond inhibitor with optional lubricant and antioxidant to obtain a powder package; mix the semi-crystalline polyamide, amorphous polyamide and powder package evenly , get the main material;
[0034] S2. Melting extrusion granulation: the main material is metered and fed from the main feed port of the twin-screw extruder through a weight loss scale, and the glass ore fiber is measured through a weight loss scale from the side feed port of the twin-screw extruder The materials are fed, and each material is melted and extruded in a twin-screw extruder, cooled by water, and pelletized to obtain the high-glass mineral fiber content and high-gloss polyamide material.
[0035] It should be noted that the lubricant and antioxidant can be selectively added according to the actual...

[0043] S1. Mixing materials: Put hydrogen bond inhibitors, lubricants and antioxidants into a high-speed mixer, mix at a speed of 600r / min for 2 minutes, mix well and evenly to form a powder package, and set aside; PA6, PA6I and the above powder package Put it into a low-speed mixer, mix at a speed of 100r / min for 5 minutes, mix well and evenly to form the main ingredient, and set aside;
[0044] S2. Melt extrusion granulation: The main material is metered and fed from the main feeding port of the twin-screw extruder through a weight loss scale, and the chopped glass fibers are separately passed through the weight loss weighing machine through the side feeding port of the twin-screw extruder. It is called metering feed; the temperatures of each section of the twin-screw extruder are: 210°C, 235°C, 250°C, 250°C, 245°C, 245°C, 245°C, 235°C, 225°C, 225°C, the head temperature The temperature is 250°C, and the screw speed is 400r / min; the material is fully fused under the shearing...
