将木质素基补强填料(LRF)分别采用干混、水混、油混(疏水处理填料)3种方法与苯乙烯-丁二烯-苯乙烯共聚物(SBS)和高苯乙烯(HS)混炼制备了SBS/HS/LRF共混发泡材料,并对其断面形貌、物理及机械性能进行了观察和测试。结果表明,相对于干混和水混,油混LRF使发泡材料的泡孔大小更加均匀,材料的抗拉强度、断裂伸长率、撕裂强度分别提高了11%、19%、12%,磨耗减小了19%。 Lignin-based reinforcing fillers (LRF) were respectively blended with styrene-butadiene-styrene copolymer (SBS) and high-styrene (HS) SBS / HS / LRF blends were prepared by mixing, and their cross-section morphology, physical and mechanical properties were observed and tested. The results showed that the oil-mixed LRF made the foam cell size more uniform than the dry mixed water, and the tensile strength, elongation at break and tear strength increased by 11%, 19%, 12% Abrasion reduced by 19%.
