摘要
针对废旧风电叶片粉体材料(WWTB)回收加工高值化利用问题,以 WWTB(平均粒径尺寸 φ＜2 mm)为原料,采用三种不同的改性剂对其进行活化改性修饰,选择出较佳的改性剂及用量,得到改性修饰废旧风电叶片粉体材料(GWWTB).采用熔融共混方式制备改性修饰废旧风电叶片粉体/聚丙烯复合材料(GWWTB/PP),考察GWWTB含量对GWWTB/PP复合材料力学性能、热稳定性能、润湿性能和断裂面微观形貌的影响.结果表明:采用质量分数 4%的 Z-6173 改性效果最佳,活化指数提高了 78.6%.当GWWTB质量分数为6%时,GWWTB/PP复合材料热稳定性最高,拉伸强度和冲击强度最大,热失重5%分解温度提高了 11.7%,拉伸强度和冲击强度分别提高了 22.89%和 178.54%,GWWTB/PP复合材料的润湿性能随着GWWTB含量的增加而提高,GWWTB/PP复合材料亲水性增强.
Abstract
Aiming at the high value utilization of waste wind turbine blade powder material(WWTB)recycling and processing,WWTB(average particle size φ<2 mm)was used as raw material,it was activated and modified by three different modifiers,and the better modifier and dosage were selected to obtain modified waste wind turbine blade powder material(GWWTB).The modified waste wind turbine blade powder/polypropylene composite(GWWTB/PP)was prepared by melt blending.The effects of GWWTB content on the mechanical properties,thermal stability,wettability and fracture surface morphology of GWWTB/PP composite were investigated.The results showed that mass fraction 4%Z-6173 had the best modification effect,the activation index was increased by 78.6%.When the mass fraction of GWWTB was 6%,the thermal stability,tensile strength and impact strength of GWWTB/PP composite material were the best.The thermal decomposition temperature of 5%weight loss was increased by 11.7%,the tensile strength and impact strength were increased by 22.89%and 178.54%,respectively.The wettability of GWWTB/PP composite material increased with the increase of GWWTB content,enhancing the hydrophilicity of GWWTB/PP composite material.
