摘 要:采用共沉淀-脫水法制備了黑液-蒙脫土(BL-MMT)新型復合填料,并將其與順丁橡膠(BR)機械共混制備了BL-MMT/BR復合材料。對復合材料進(jìn)行了XRD、SEM、DSC和TGA分析,并研究了復合材料的熱氧老化性能和力學(xué)性能。XRD和SEM結果表明BL-MMT在復合材料中分散明顯優(yōu)于純MMT,與橡膠的相容性更好;DSC結果顯示BL-MMT復合填料的加入形成了結合膠并促進(jìn)了BR結晶,由于MMT的良好分散以及結合膠和結晶的形成,BR的力學(xué)性能、熱氧老化性能和熱穩定性得到了顯著(zhù)提高。BL-MMT制備工藝環(huán)保,是一種具有應用前景的橡膠補強劑。

Abstract:A novel rubber filler,black liquor-montmorillonite complex(BL-MMT),was prepared by dehydration of a mixture of montmorillonite and black liquor and used in the preparation of cis-butadiene rubber(BR)composites by mechanical mixing method. The BL-MMT/BR composites were characterized using XRD,TEM,DSC and TGA. The mechanical and aging properties of composites were also tested. Experimental results of XRD and SEM indicated that BL-MMT was well-dispersed in the rubber because of the presence of lignin. The results of DSC indicated that the bound rubber had formed in BR composites and the crystallization of BR was induced due to the addition of BL-MMT. The mechanical and aging properties of composites were greatly improved due to the well-dispersion of MMT and the formation of bound rubber and crystallization. All experimental results indicated that this BL-MMT complex could be a promising reinforcing agent in rubber for environment benefits.
