Research on Mechanical Properties and Wettability of Waste Wind Turbine Blade Powder/Polypropylene Composite
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.
