Flame-retardant reinforced polyamide composite material as well as preparation method and application thereof

The invention discloses a flame-retardant reinforced polyamide composite material as well as a preparation method and application thereof. The flame-retardant reinforced polyamide composite material comprises the following components: polyamide resin, organic hypophosphite, surface-coated microporous inorganic phosphite, an anticorrosive agent, a silicone master batch and fibers, wherein the anticorrosive agent comprises esterified polyol, and at least one of zinc borate and zinc stannate. The microporous inorganic phosphite synergistic flame-retardant reinforced polyamide composite material based on surface treatment provided by the invention not only has high stability, good mechanical properties and excellent electrical properties, but also has very outstanding physical abrasion resistance and chemical corrosion resistance in the processing process, and has a wide application prospect. 本发明公开了一种阻燃增强聚酰胺复合材料及其制备方法和应用。这种阻燃增强聚酰胺复合材料包括以下组分：聚酰胺树脂、有机次磷酸盐、表面包覆的微孔型无机亚磷酸盐、防腐蚀剂、硅酮母料和纤维；其中，防腐蚀剂包括酯化多元醇，以及硼酸锌、锡酸锌中的至少一种。本
