摘要将酒糟磨碎并过筛之后与RDP膨胀型阻燃体系以不同的比例进行复配后加入到聚乳酸中，通过转矩流变仪将阻燃剂和聚乳酸的混合物混合均匀，然后通过注塑机制备出复合材料。对复合材料进行热重分析（TG）、氧指数测试（OI）、红外测试（FTIR）以及扫描电镜分析(SEM)以此来分析材料的阻燃性能，对复合材料进行拉伸测试分析其力学性能。结果表明：随着RDP的增加，氧指数逐渐增大，但RDP添加量大时会出现熔滴现象，说明RDP阻燃效果好，RDP添加量增大时，残炭量逐渐变小，说明RDP促进成炭的能力不如酒糟，综合来说，RDP加入量为10%左右时，协同阻燃的效果最好。拉伸测试结果表明，随着RDP含量的增加，拉伸强度先增后减。33415

Title The new type of Intumescent Flame Retardant Poly(lactic acid)
Abstract
DDG and RDP were selected to form novel intumescent flame retardant system in different proportions,and then blend with Poly(lactic acid). Flame Retardants and Poly(lactic acid) will be used to mix with torque rheometer uniformly ,prep -aring the composites with injection molding machine. flame retardant propert
-ies of the composite materials were studied through thermo gravimetric analysis,oxygen index test,FTIR and scanning electron microscopy. mechanical properties of the composite materials were analyzed through the tensile test .The results show that with the increase of addition amount of RDP in the composite materials, oxygen index increases,but the phenomenon of dripping becomes serious.Residue of the composite materials reduce with the increase of addition amount of RDP,so flame retardant properties of RDP is good,but the effect of promoting charring is poor than DDG.In summary,when addition amount of RDP is about 10%,synergistic flame retardant effect is the best.the result of tensile test shows that with the increase of addition amount of RDP in the composite materials,tensile strength increase and then reduce later.
