【摘要】：在對某含釩頁巖提釩渣進行物理化學(xué)特性分析的基礎(chǔ)上,對其進行了表面改性,以作為聚合物填料。對比了3種偶聯(lián)劑對釩尾渣的改性效果及對復(fù)合材料的力學(xué)性能影響,并確定了該釩尾渣的表面改性工藝。結(jié)果表明:鋁酸酯偶聯(lián)劑DL-411對釩尾渣改性效果最好,其與釩尾渣質(zhì)量比為1.2%,改性溫度為100℃時,釩尾渣活性指數(shù)達95.53%。FTIR分析表明,DL-411在釩尾渣表面結(jié)合能力最強。XRD分析表明,釩尾渣對聚丙烯(PP)有異相成核作用,誘導(dǎo)PP中β晶型形成,DL-411改性能顯著增強成核作用,使復(fù)合材料具有更高的強度和更好的韌性。當(dāng)改性釩尾渣填充量(改性釩尾渣與聚丙烯的質(zhì)量比)為10%時,復(fù)合材料的拉伸強度、抗沖擊強度和抗彎曲強度分別為47.51MPa、38.43 k J/m~2、59.57 MPa。
[Abstract]:Based on the analysis of the physical and chemical properties of vanadium-bearing shale-containing vanadium-extracted slag, the surface of the slag was modified to be used as polymer filler. The effects of three coupling agents on the modification of vanadium tail slag and the mechanical properties of the composite were compared, and the surface modification process of the vanadium tail slag was determined. The results show that DL-411 has the best effect on the modification of vanadium tail slag. When the mass ratio of vanadium tail slag to vanadium tail slag is 1.2, and the modification temperature is 100 鈩，
