Problems solved by technology

[0003] However, the compatibility between nylon and ABS is poor, and it is often necessary to add a compatibilizer to it to improve the toughness of the PA / ABS alloy material; and due to the existence of butadiene segments in ABS, it is bound to cause PA / ABS alloy The tensile strength of the material is reduced, but the existing compatibilizers cannot solve this problem, so how to achieve toughness is a major difficulty in the preparation of PA / ABS alloy materials

Description

technical field [0001] The invention relates to the technical field of polymer alloy materials, in particular to a toughened PA / ABS alloy material and a preparation method thereof. Background technique [0002] PA (also known as nylon, polyamide) and ABS are two important plastic products, among which nylon has excellent mechanical properties, heat resistance, wear resistance, chemical resistance and self-lubrication, and low friction coefficient. It has a certain flame retardancy and is easy to process. It is suitable for filling with glass fiber and other fillers to improve performance and expand the scope of application. ABS is a thermoplastic polymer material with high strength, good toughness and easy processing. , according to the different proportions of the three monomers, it can be applied to various plastic products, and its main advantage is low price. By making two kinds of plastics into alloys, new products with excellent performance can be obtained. [0003] H...
