Polyamide material for improving adhesion effect of paint as well as preparation method and application of polyamide material

The invention discloses a polyamide material for improving the adhesion effect of paint as well as a preparation method and application of the polyamide material. The polyamide material is composed ofthe following components in percentages by weight: 20-90% of semi-crystalline polyamide, 8-70% of glass mineral fibers, 1-6% of an ion copolymer, 0.2-3% of a plasticizer, 0.3-0.5% of a lubricant, 0.2-0.6% of an agent resistant to long-term heat aging, and 0.2-0.5% of an antioxidant. According to the method, the ion copolymer having a carboxyl side group in a molecular side chain and the polyamideplasticizer capable of suppressing hydrogen bonding from being formed among molecular chains of the semi-crystalline polyamide and reducing the crystallization ability of a polyamide material are used to modify the semi-crystalline polyamide material to obtain high fluidity and an unexpectedly good coating adhesion effect. 本发明公开了一种改善涂料附着效果的聚酰胺材料及其制备方法和应用，由如下重量百分比的组分制成：半结晶性聚酰胺20-90％、玻矿纤维8-70％、离子共聚物1-6％、增塑剂0.2-3％、润滑剂0.3-0.5
