木质素填充改性SBS弹性体的性能
Properties of styrene-butadiene-styrene block copolymer elastomer filled and modified by lignin
摘要
Abstract
The styrene/butadiene/styrene block copolymer(SBS)membrane materials filled with various contents of corn straw lignin were prepared through solution casting. The effects of lignin contents on the performances of SBS were studied by mechanical property testing,dynamic mechanical analysis(DMA) and cone calorimeter test. The tensile test results showed that the mechanical properties of SBS elastomer could be improved by filling with lignin. The tensile strength and elongation at break for the SBS with 6% lignin were 22.8MPa and 2400%,respectively. Compared with the unfilled SBS,the tensile strength and elongation at break of modified SBS increased by 32% and 15% respectively. The DMA analysis indicated that the storage modulus and the glass-transition temperature(Tg)were also improved by filling with lignin. The cone calorimeter test results showed that the total heat release(THR)and the specific extinction area(SEA)were reduced by filling with lignin. The rate of mass loss was slower,which indicated that the flame retardant property of SBS was improved by filling with corn straw lignin.关键词
