摘 要:將木質(zhì)素基補強填料(LRF)分別采用干混、水混、油混(疏水處理填料)3種方法與苯乙烯-丁二烯-苯乙烯共聚物(SBS)和高苯乙烯(HS)混煉制備了SBS/HS/LRF共混發(fā)泡材料,并對其斷面形貌、物理及機械性能進(jìn)行了觀(guān)察和測試。結果表明,相對于干混和水混,油混LRF使發(fā)泡材料的泡孔大小更加均勻,材料的抗拉強度、斷裂伸長(cháng)率、撕裂強度分別提高了11%、19%、12%,磨耗減小了19%。

Abstract:Styrene-butadiene-styrene copolymer(SBS)/high styrene(HS)/lignin-based reinforcing filler (LRF) blends were prepared by dry mixed, wet mixed or water repellent treatment method. The phase morphology, physical and mechanical properties of SBS/HS/LRF blends were evaluated. Experimental data indicated that LRF subjected to water repellent treatment method showed better dispersion in the matrix than the one treated by the dry mixed or wet mixed method, the foam of this filled matrix had the ideal structure while the tensile strength, elongation and tear strength of SBS/HS/LRF blends were increased by 11%, 19% and 12%, respectively, and the abrasion was decreased by 19%.
Key words:lignin-based reinforcing filler; SBS; HS; foaming
