摘要
偶聯劑適用于各種不同的有機高聚物和無機填料的復合材料體系,高嶺土表面能夠與偶聯劑作用,經偶聯劑改性后的高嶺土與有機相的相容性提高。常用的偶聯劑有硅烷偶聯劑、鈦酸酯偶

  偶(ou)(ou)(ou)聯劑(ji)(ji)適用(yong)于(yu)各種(zhong)不同的(de)(de)(de)有(you)機(ji)(ji)(ji)高(gao)(gao)(gao)(gao)聚物和無機(ji)(ji)(ji)填料(liao)的(de)(de)(de)復合材料(liao)體(ti)系,高(gao)(gao)(gao)(gao)嶺土(tu)表面能夠與(yu)偶(ou)(ou)(ou)聯劑(ji)(ji)作用(yong),經偶(ou)(ou)(ou)聯劑(ji)(ji)改性(xing)(xing)后的(de)(de)(de)高(gao)(gao)(gao)(gao)嶺土(tu)與(yu)有(you)機(ji)(ji)(ji)相的(de)(de)(de)相容(rong)性(xing)(xing)提高(gao)(gao)(gao)(gao)。常(chang)用(yong)的(de)(de)(de)偶(ou)(ou)(ou)聯劑(ji)(ji)有(you)硅(gui)烷(wan)偶(ou)(ou)(ou)聯劑(ji)(ji)、鈦酸酯偶(ou)(ou)(ou)聯劑(ji)(ji)、鋁(lv)鈦偶(ou)(ou)(ou)聯劑(ji)(ji)以及其他(ta)的(de)(de)(de)金屬偶(ou)(ou)(ou)聯劑(ji)(ji)。偶(ou)(ou)(ou)聯劑(ji)(ji)分子的(de)(de)(de)一(yi)(yi)(yi)端能夠與(yu)高(gao)(gao)(gao)(gao)嶺土(tu)表面的(de)(de)(de)Si-O或Al-O化學結合,另一(yi)(yi)(yi)端延(yan)伸(shen)在外賦(fu)予高(gao)(gao)(gao)(gao)嶺土(tu)表面親有(you)機(ji)(ji)(ji)相的(de)(de)(de)性(xing)(xing)質。偶(ou)(ou)(ou)聯劑(ji)(ji)改性(xing)(xing)工藝相對(dui)簡單,但(dan)目前(qian)只有(you)硅(gui)烷(wan)偶(ou)(ou)(ou)聯劑(ji)(ji)及鈦酸酯偶(ou)(ou)(ou)聯劑(ji)(ji)的(de)(de)(de)作用(yong)機(ji)(ji)(ji)理(li)比(bi)較清楚(chu),而對(dui)于(yu)其他(ta)偶(ou)(ou)(ou)聯劑(ji)(ji)的(de)(de)(de)機(ji)(ji)(ji)理(li)還有(you)待進一(yi)(yi)(yi)步研(yan)究。

  橡膠(jiao)補(bu)強(qiang)(qiang)填(tian)(tian)充(chong)劑(ji)(ji)(ji):炭(tan)(tan)(tan)黑(hei)是目前較常用的(de)(de)(de)(de)橡膠(jiao)補(bu)強(qiang)(qiang)填(tian)(tian)充(chong)劑(ji)(ji)(ji)。隨(sui)著(zhu)復(fu)(fu)合(he)材(cai)料(liao)科學的(de)(de)(de)(de)發(fa)展,無(wu)機物(wu)經(jing)適當處理后代(dai)替炭(tan)(tan)(tan)黑(hei)作為橡膠(jiao)補(bu)強(qiang)(qiang)填(tian)(tian)充(chong)劑(ji)(ji)(ji),不僅可以(yi)降(jiang)低原(yuan)料(liao)成(cheng)(cheng)本,節約資(zi)源,而且有利(li)于擴大原(yuan)料(liao)來(lai)源,合(he)理利(li)用資(zi)源。煤系高嶺土是煤炭(tan)(tan)(tan)開采過(guo)(guo)程中產生的(de)(de)(de)(de)廢(fei)棄物(wu),其中有些(xie)煤系高嶺土通過(guo)(guo)高嶺土加工(gong)設(she)備,高嶺土加工(gong)技術可看成(cheng)(cheng)是硅酸鹽礦物(wu)和類似(si)于炭(tan)(tan)(tan)黑(hei)的(de)(de)(de)(de)有機碳質物(wu)組成(cheng)(cheng)的(de)(de)(de)(de)復(fu)(fu)合(he)體,通過(guo)(guo)相對富集、超細粉碎、表面改性處理等方法,可將(jiang)其代(dai)替通用炭(tan)(tan)(tan)黑(hei)作為橡膠(jiao)的(de)(de)(de)(de)補(bu)強(qiang)(qiang)填(tian)(tian)充(chong)劑(ji)(ji)(ji)。
