Scratch-resistant polyamide composition and preparation method thereof

The invention discloses a scratch-resistant polyamide composition and a preparation method thereof. The scratch-resistant polyamide composition is prepared from the following raw materials in percentage by mass: 40-80% of a polyamide resin, 10-40% of a glass fiber, 0.5-4% of organo-siloxane, 0.3-1.5% of polytetrafluoroethylene, 5-15% of a polyethylene-crylic acid ionomer, 0.2-1.0% of an antioxidant and 0.1-1.0% of a lubricant. The invention further discloses a preparation method of the scratch-resistant polyamide composition. The scratch-resistant polyamide composition disclosed by the invention is good in scraping resistance, mechanical property and coloring property, no conspicuous scratch marks are caused in five-finger scratch tests, and components and elements made of the composition are not easily scratched in long-term use. 本发明公开了种耐刮擦聚酰胺组合物及其制备方法。种耐刮擦聚酰胺组合物，由以下质量百分比的原料组成：聚酰胺树脂40％-80％；玻璃纤维10％-40％；有机硅氧烷0.5％-4％；聚四氟乙烯0.3％-1.5％；聚乙烯-丙烯酸离聚物5％-15％；抗氧剂0.2％-1.0％；润滑剂0.1％-1.0％。同时也公开了种耐刮擦聚酰胺组合物的制备方法。本发明制得的耐刮擦聚酰胺组合物
