改性(xing)(xing)(xing)(xing)C5氫化(hua)石(shi)(shi)油(you)樹(shu)(shu)脂是(shi)石(shi)(shi)油(you)裂解(jie)所副產的C5、C9等(deng)碳氫組份，經(jing)前處理、聚(ju)(ju)合、蒸餾等(deng)工藝生產的一(yi)種熱(re)塑性(xing)(xing)(xing)(xing)樹(shu)(shu)脂，它(ta)(ta)不是(shi)高聚(ju)(ju)物(wu)，而是(shi)分(fen)子量介于300-3000的低聚(ju)(ju)物(wu)。兼有(you)(you)(you)C5石(shi)(shi)油(you)樹(shu)(shu)脂和(he)(he)C9石(shi)(shi)油(you)樹(shu)(shu)脂的優點。它(ta)(ta)具有(you)(you)(you)酸(suan)值低，混(hun)溶(rong)性(xing)(xing)(xing)(xing)好(hao)，耐(nai)(nai)水(shui)、耐(nai)(nai)乙醇和(he)(he)耐(nai)(nai)化(hua)學(xue)品等(deng)特(te)性(xing)(xing)(xing)(xing)，對酸(suan)堿具有(you)(you)(you)化(hua)學(xue)穩定(ding)，并有(you)(you)(you)調(diao)節粘(zhan)性(xing)(xing)(xing)(xing)和(he)(he)熱(re)穩定(ding)性(xing)(xing)(xing)(xing)好(hao)的特(te)點。由于結構中不含極性(xing)(xing)(xing)(xing)基團，因此(ci)有(you)(you)(you)良(liang)好(hao)的耐(nai)(nai)水(shui)性(xing)(xing)(xing)(xing)、耐(nai)(nai)酸(suan)堿性(xing)(xing)(xing)(xing)、耐(nai)(nai)候性(xing)(xing)(xing)(xing)和(he)(he)耐(nai)(nai)光老化(hua)性(xing)(xing)(xing)(xing)，在有(you)(you)(you)機溶(rong)劑(ji)(ji)中，特(te)別是(shi)在石(shi)(shi)油(you)溶(rong)劑(ji)(ji)中，有(you)(you)(you)良(liang)好(hao)的溶(rong)解(jie)性(xing)(xing)(xing)(xing)，同其(qi)它(ta)(ta)樹(shu)(shu)脂的相溶(rong)性(xing)(xing)(xing)(xing)很好(hao)，還具有(you)(you)(you)脆(cui)性(xing)(xing)(xing)(xing)、增粘(zhan)性(xing)(xing)(xing)(xing)、粘(zhan)結性(xing)(xing)(xing)(xing)和(he)(he)可塑性(xing)(xing)(xing)(xing)。一(yi)般不單獨使用，而是(shi)作(zuo)為促進(jin)劑(ji)(ji)、調(diao)節劑(ji)(ji)、改性(xing)(xing)(xing)(xing)劑(ji)(ji)和(he)(he)其(qi)它(ta)(ta)樹(shu)(shu)脂一(yi)起使用。　

產品應用領域：

          改性C5氫化石油樹脂在(zai)熱(re)熔膠、黏合劑(ji)、膠粘(zhan)(zhan)(zhan)劑(ji)以及橡(xiang)膠和輪(lun)胎(tai)領(ling)域(yu)，適(shi)用于子午線(xian)輪(lun)胎(tai)等高(gao)要(yao)求(qiu)的(de)橡(xiang)膠制品，不但能增(zeng)大膠粒間(jian)的(de)粘(zhan)(zhan)(zhan)合力，而(er)(er)且(qie)能夠(gou)提高(gao)膠粒和簾(lian)子線(xian)之間(jian)的(de)粘(zhan)(zhan)(zhan)合力；而(er)(er)在(zai)熱(re)熔膠、黏合劑(ji)、膠粘(zhan)(zhan)(zhan)劑(ji)領(ling)域(yu)，改性C5氫化石油樹脂不但能夠(gou)提供更好的(de)初始粘(zhan)(zhan)(zhan)性，而(er)(er)且(qie)能夠(gou)像(xiang)松香樹脂那樣(yang)，可以用來調節膠劑(ji)與(yu)樹脂混合物(wu)粘(zhan)(zhan)(zhan)度的(de)持(chi)久性和黏結強度。
