Halogen-free flame-retardant bio-based nylon material and preparation method thereof

The invention discloses a halogen-free flame-retardant bio-based nylon material and a preparation method thereof. The halogen-free flame-retardant bio-based nylon material comprises the following components: 92-97% of nylon 56 resin, 3-8% of a silicon-nitrogen flame retardant, 0-0.5% of an antioxidant and 0-0.5% of a lubricant. By compounding the novel silicon-nitrogen flame retardant and the bio-based nylon material, the problem of thermal decomposition of the flame retardant in the preparation process can be effectively solved, so that the addition amount of the flame retardant can be effectively reduced, and the nylon material can be ensured to have excellent flame retardance. 本发明公开了一种无卤阻燃生物基尼龙材料及其制备方法，其中所述无卤阻燃生物基尼龙材料包括如下组分：尼龙56树脂为92-97％，硅氮类阻燃剂为3-8％，抗氧剂为0-0.5％，润滑剂为0-0.5％。本发明通过采用新型的硅氮类阻燃剂与生物基尼龙材料进行复配能够有效解决制备过程中阻燃剂的热分解问题，从而能够有效减少阻燃剂的添加量同时还能够保证尼龙材料具有优异的阻燃性能。
