Abstract

The invention provides a super-rigid nylon 66 modified material. The super-rigid nylon 66 modified material is prepared by the following method: 1) uniformly stirring PA66, wollastonite powder and ultra-rigid glass fibers as raw materials to prepare a mixture, wherein the mixture comprises the following components in parts by weight: 60-70 parts of PA66, 20-30 parts of the wollastonite powder and20-30 parts of the ultra-rigid glass fibers; 2) extruding by adopting a double-screw extruder; and 3) granulating to prepare the super-rigid scratch-resistant nylon 66 modified material. The super-rigid nylon 66 modified material has super-rigid performance.

Description

technical field [0001] The invention relates to a superrigid nylon 66 modified material, which belongs to the technical field of nylon engineering plastics. 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, PAll, PAl2, PA46, PA610, PA612, PAl010, etc., as well as many new...
