摘　　要：先合成OA-POSS与DPA,然后将其引入到WF/PP木塑复合材料中,通过热压成型方法制备阻燃WF/PP木塑复合材料,进行热失重分析及阻燃性能、力学性能测试,探究了阻燃木塑复合材料的热稳定性能、燃烧性能和力学性能。结果表明:DOPO、DPA和OA-POSS的加入一定程度上提高了复合材料的初始热分解温度,降低了热分解速率,明显提高材料的热解残余物质量。DOPO,DPA和OA-POSS的加入能够显著提高复合材料的阻燃性能,复合材料的残炭量明显增加,最高增加228.05%。DOPO的加入使材料力学性能下降,而DPA和OA-POSS的加入一定程度上增强了复合材料的力学性能。In this paper,octaaminopropyl POSS(OA−POSS)and DOPO derivatives(DPA)were synthesized,and then DOPO,DPA and OA−POSS were introduced into WF/PP wood-plastic composites.The flame-retardant WF/PP wood-plastic composites were prepared by the hot pressing method,and the thermal decomposition,combustion properties and mechanical properties of the flame-retardant wood-plastic composites were explored.Thermogravimetric(TG)analysis shows that the addition of DOPO,DPA and OA−POSS increase the initial thermal decomposition temperature of the composites to a certain extent,reduce the thermal decomposition rate,and significantly improve the quality of the pyrolysis residue of the material.The cone calorimeter(CONE)test shows that the addition of DOPO,DPA and OA−POSS can significantly improve the flame retardant properties of composites.The carbon residue of the composite material increased significantly,with a maximum increase of 228.05%.The addition of DOPO decreases the mechanical properties of the material,while the addition of DPA and OA−POSS can enhance the mechanical properties of the composites.
