Rigid-tough balanced polyamide 56 material based on core-shell structure and preparation method of rigid-tough balanced polyamide 56 material

The invention discloses a rigid-tough balanced polyamide 56 material based on a core-shell structure, which is prepared from the following raw material components in percentage by mass: 66 to 75 percent of PA56 resin, 8 to 15 percent of PP resin, 10 to 18 percent of flexibilizer, 0.2 to 0.6 percent of antioxidant and 0.3 to 0.8 percent of lubricant. Wherein the toughening agent is a glycidyl methacrylate grafted ethylene-octylene copolymer. According to the invention, the PP resin and the glycidyl methacrylate grafted ethylene-octene copolymer (POE-g-GMA) are compounded to obtain the core-shell rubber which takes the high-strength and high-modulus PP resin as a core and takes the high-toughness and high-reactivity POE-g-GMA as a shell, and the core-shell rubber is used for modifying the PA56; the impact strength of the PA56 can be obviously improved under the condition of ensuring that the PA56 has good tensile strength and tensile modulus. 本发明公开了一种基于核壳结构的刚韧平衡聚酰胺56材料，以质量百分比计，其原料包括如下组分：PA56树脂66％-75％、PP树脂8％-15％
