Problems solved by technology

Nylon material itself has very excellent properties, such as high strength, good temperature resistance, etc., but after long-term impact, nylon material is prone to cracking, which is mainly due to the lack of toughness of the material and the inability to absorb the impact stress. Therefore, for The development of nylon materials with good toughness has good positive significance, and the technical solutions to be introduced below are produced under this background

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a modified nylon alloy material. Background technique [0002] Nylon material is a very important engineering plastic, widely used in automobiles, electronics, construction and other fields. Nylon material itself has very excellent properties, such as high strength, good temperature resistance, etc., but after long-term impact, nylon material is prone to cracking, which is mainly due to the lack of toughness of the material and the inability to absorb the impact stress. Therefore, for The development of nylon materials with good toughness has good positive significance, and the technical solutions to be introduced below are produced under this background. Contents of the invention [0003] The object of the present invention is to provide a modified nylon alloy material which has better toughness and thus is ideally resistant to impact cracking.
