Embodiment 1-2

[0014] Table 1 is the ratio of the raw materials of the composite material in Example 1-2 and the performance parameters of the composite material obtained. The preparation method of the composite material in Example 1-2 is as follows: add all other components in the proportioning scheme except polyamide and reinforcing modifier to a high-speed mixer and mix evenly, then take it out. Add polyamide from the main feeding port of the twin-screw extruder, add materials mixed by a high-speed mixer at the first side feeding port, and then add reinforcing modifier at the second side feeding port to make the technical proposal All materials are mixed evenly in the twin-screw extruder, and the temperature of the extruder from the feed section to the die head is 250°C, 290°C, 290°C, 290°C, 290°C, 290°C, 285°C, 280°C , 280°C, extrude, cool, and pelletize to obtain the required composite material of the present invention. The performance parameters of the composite material obtained were...

Abstract

The invention discloses a high-content glass fiber reinforced polyamide composite material and a preparation method thereof. A raw material composition of the high-content glass fiber reinforced polyamide composite material contains polyamide 66, antioxygen 1010, antioxygen 168, black master, a lubricating agent and glass fiber. The glass fiber reinforced polyamide composite material adopts a special lubricating agent adding method and enables the fluidity and the surface problem of the high-content glass fiber reinforced polyamide composite material to be solved.

Description

technical field [0001] The invention specifically relates to a high-content glass fiber reinforced polyamide composite material and a preparation method thereof. Background technique [0002] Polyamide (PA, commonly known as nylon) is the first resin developed by DuPont in the United States for fiber, and it was industrialized in 1939. In the 1950s, the development and production of injection molding products began to replace metals to meet the requirements of lightweight and cost-reducing downstream industrial products. PA has good comprehensive properties, including mechanical properties, heat resistance, wear resistance, chemical resistance and self-lubricating properties, low friction coefficient, certain flame retardancy, easy processing, suitable for glass fiber and Other fillers are filled and modified to improve performance and expand application range. There are many varieties of PA, including PA6, PA66, PA11, PA12, PA46, PA610, PA612, PA1010, etc., as well as man...
