通过研究[C4mim]Br、[C7mim]Br、[C8mim]Br、[BPy]Br 共4种离子液体对白炭黑、膨润土、高岭土、硅藻土、珍珠岩(深、浅色)共6种不同无机材料进行改性,并对改性前后的无机材料进行了FT-IR、TG和氮气吸附-脱附比表面积分析。应用改性后的无机材料与橡胶混炼制胶,测定其导热系数。结果表明,无机材料经离子液体改性后均比未改性的导热系数有所提高,其中,[C4mim]Br 改性无机材料的导热系数提高幅度最大,[C4mim]Br改性的高岭土的导热系数高达0.389W/(m·K),与改性前的导热系数相比提高了89.76%。

The modification of white carbon black,bentonite,kaolin,diatomaceous earth and perlite (deep and shallow) six different inorganic materials loaded with [C4mim]Br,[C7mim]Br,[C8mim]Br and [BPy]Br four ionic liquids was studied. FT-IR,TG and nitrogen adsorption-desorption of the specific surface area of these inorganic materials before and after modification were conducted. These modified inorganic fillers were then kneaded into rubber separately,and the thermal conductivity coefficients of rubber were measured. The thermal conductivity coefficients of these six kinds of inorganic materials modified by ionic liquids were all greater than those before modification. Wherein, the thermal conductivity coefficients of all these inorganic materials modified by [C4mim]Br increased the most. The thermal conductivity coefficient of Kaolin modified by [C4mim]Br was the highest,up to 0.389 W/(m?K),89.76%greater than the unmodified.
