Problems solved by technology

However, studies have shown that when rigid particles are added to PA66, the toughness of the material is generally reduced while increasing the rigidity of the material. The higher the filling amount, the more significant the effect; Increased toughness, improved low-temperature impact performance, but reduced the rigidity of the material

Abstract

The invention discloses a PA66 / tremolite / MBS composite material and a preparing method thereof. PA66, a toughening agent, tremolite, a lubricating agent, antioxidant and compatilizer are prepared into low-cost high-performance engineering plastic alloy. Methyl methacrylate-butadiene-styrol copolymer (MBS) is adopted to carry out toughening modification research on PA 66, the copolymer is the toughening agent of a core-shell structure, and bisphenol A type epoxy resin (DGEBA) is used as a bulking agent. The PA66 / tremolite / MBS composite material is high in mixing performance complementarity and processing process, and a PA66 / tremolite / MBS alloy product excellent in comprehensive performance can be obtained through blending, screw extruding and injection molding.

Description

technical field [0001] The invention relates to a PA66 / tremolite / MBS composite material and a preparation method thereof. Background technique [0002] PA66 is a crystalline polymer. As an engineering plastic, it has excellent comprehensive properties and is widely used in automobiles, electronics, electrical equipment, mechanical parts, and transportation equipment. However, the heat resistance and acid resistance of PA66 are poor, and the impact strength is low in dry state and low temperature; the water absorption rate and molding shrinkage rate are relatively large, which affects the dimensional stability and electrical properties of the product. In order to be suitable for the development of polyamide in different fields, this requires polyamide to have higher mechanical strength and heat resistance. Mechanical parts and polyamide for railway locomotives all put forward high requirements on the mechanical properties and dimensional stability of PA66. Therefore, the mo...
