Abstract

The invention provides a glass fiber reinforced PA6 composition and a preparation method thereof. The composition is composed of 30-60 parts of PA6, 1-10 parts of PA66, 25-45 parts of glass fiber, 0-5 parts of toughening agent, and 5-10 parts of The nucleating agent and 5-10 parts of surface improving agent are prepared by mixing, extrusion and granulation. The invention adopts chopped glass fiber with rectangular cross section, which can reduce the phenomenon of floating fiber; in addition, the chopped glass fiber cooperates with nylon 66 and surface improving agent to jointly improve the surface of the glass fiber reinforced PA6 material after injection molding Floating fibers, and improve the mechanical properties and compressive properties of modified glass fiber reinforced PA6 compositions.

Description

technical field [0001] The invention belongs to the field of polymer composite materials, and in particular relates to a glass fiber reinforced PA6 composition 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. Polyamide began to develop and produce injection molding products in the 1950s 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-lubrication, and has a low coefficient of friction, as well as certain flame retardancy, and is easy to process. [0003] At present, in order to strengthen the toughness of PA and reduce its production cost, most nylon materials are modified by adding appropriate glass fibers to them, but the pr...
