Recycled Polypropylene/Kenaf Fiber/Halloysite(rPP/rNR/KF/Hall)smart composites:The influence of bio-compatibilizer addition on Tensile,Morphological and Heat Combustion Properties

摘要

Had been successfully synthesized rPP/DVB/PP-AA/rNR/KF//Hall+ZB smart composite in solution reactive processes with various recycled Natural Rubber(rNR)bio-compatibilizer concentration.The addition of rNR bio-compatibilizer improved the total capacity loading(Hall and KF)fdler to reach the optimum concentration.The addition of 3% rNR is capable to increase capacity of total loading filler KF and Hall up to 46% as the optimum condition(KH4).At optimum conditions it can increase the Tensile Strength(TS)and Elongation(Elo)up to 16% and 17% respectively,and decrease the Young Modulus(YM)to 1% compared to that the composites without rNR(KH1).The rNR plasticizer serves as a bio-compatibilizer that can increase the loading fdler capacity and well interaction,finally,it can increase the TS properties.The increase of total loading filler KF and Hall to 46%(KH4)can also improve the inflammability of the composites.The Heat combustion(Hg)of KH1 without rNR was 42.3 kJ/g and at optimum condition the Hg of KH4 increases 4.8%,compared to that of KH1.The time to Ignition(TTI)increases by 6.9%,Burning Rate(BR)decreases by 3.7% and the Heat Release(HR)increases by 2.1% compared to that of the composites without rNR(KH1).
