Effects of Environmental-friendly Modified Rubber Seed Shell on the Comprehensive Properties of High Density Polyethylene/Rubber Seed Shell Composites
This study aimed to evaluate the effects of rubber seed shell modified by high temperature superheated vapor on the comprehensive properties of high density polyethylene/rubber seed shell(HDPE/RSS)composites with two superheated vapor temperatures(200 and 220 ℃)and particle sizes of RSS(60-80,80-100 and 100-120 mesh).The target properties of the composites were analyzed using electronic universal mechanical instrument,thermogravimetric(TG),differential scanning calorimeter(DSC),scanning electron microscopy(SEM)and dynamic mechanical analysis(DMA).The results indicated that the composites with 100-120 mesh RSS particles modified at the optimum superheated vapor temperature of 200 ℃(HDPE/RSS200-3)appeared the strongest interfacial bonding ability with the excellent comprehensive analysis data.Compared to unmodified samples at the same particle size,the flexural and tensile strength of HDPE/RSS200-3 increased by 21.27%and 12.92%,respectively,Tmax1 and Tmax2 shifted toward the higher temperature value from 349.5 ℃ and 475.3 ℃ to 351.9 ℃ and 478.9 ℃,there was a marked increase for E” from 3370 to 3819 MPa but decrease for tanδ from 0.355 to 0.326.In addition,the HDPE/RSS200-3 also exhibited the relatively outstanding water resistance with the maximum water absorption and thickness swelling rates of 4.01%and 1.02%.
