乙烯基酯樹脂的介紹
乙烯(xi)(xi)基(ji)酯(zhi)樹(shu)(shu)(shu)脂(zhi)(zhi)是(shi)由雙酚(fen)型(xing)或(huo)酚(fen)醛型(xing)環(huan)氧樹(shu)(shu)(shu)脂(zhi)(zhi)與甲基(ji)丙烯(xi)(xi)酸反應得到的(de)(de)(de)一(yi)類變性(xing)環(huan)氧樹(shu)(shu)(shu)脂(zhi)(zhi),通(tong)常被稱為乙烯(xi)(xi)基(ji)酯(zhi)樹(shu)(shu)(shu)脂(zhi)(zhi)(VE),別名環(huan)氧丙烯(xi)(xi)酸樹(shu)(shu)(shu)脂(zhi)(zhi),為熱固性(xing)樹(shu)(shu)(shu)脂(zhi)(zhi).乙烯(xi)(xi)基(ji)酯(zhi)樹(shu)(shu)(shu)脂(zhi)(zhi)秉承了環(huan)氧樹(shu)(shu)(shu)脂(zhi)(zhi)的(de)(de)(de)優(you)良特性(xing),固化性(xing)和(he)(he)成型(xing)性(xing)方(fang)面更為出色,能(neng)溶解于(yu)苯乙烯(xi)(xi)以及丙烯(xi)(xi)酸系單體,由于(yu)兼(jian)具環(huan)氧和(he)(he)不(bu)(bu)飽和(he)(he)的(de)(de)(de)優(you)點,其應用領域正在不(bu)(bu)斷擴大(da).乙烯(xi)(xi)基(ji)酯(zhi)樹(shu)(shu)(shu)脂(zhi)(zhi)是(shi)由環(huan)氧樹(shu)(shu)(shu)脂(zhi)(zhi)與甲基(ji)丙烯(xi)(xi)酸通(tong)過開環(huan)加成化學反應而(er)制得.它保留了環(huan)氧樹(shu)(shu)(shu)脂(zhi)(zhi)的(de)(de)(de)基(ji)本鏈段,又有不(bu)(bu)飽和(he)(he)聚酯(zhi)樹(shu)(shu)(shu)脂(zhi)(zhi)的(de)(de)(de)良好工(gong)藝性(xing)能(neng),它在適宜條件下固化后,表現出某些(xie)特殊(shu)的(de)(de)(de)優(you)良性(xing)能(neng).
乙烯基樹脂的應用
1、 制(zhi)作(zuo)耐腐(fu)(fu)蝕FRP制(zhi)品,如玻璃鋼(gang)槽罐、管道、塔器以及耐腐(fu)(fu)蝕格柵等.
2、 防腐蝕工程(cheng),如水泥基或(huo)鐵基玻璃鋼襯里(li)、高(gao)耐腐蝕地坪,高(gao)強(qiang)度(du)FRP制品(pin),如玻璃鋼型材、體育(yu)用(yong)品(pin)、FRP船艇等.
3、 重防腐玻璃鱗片涂料、鱗片膠泥.
4、 -如UV油墨、重(zhong)防(fang)腐工業地坪等.
5、 電廠脫硫防腐,耐高溫,耐強酸強堿.
乙烯基酯樹脂(zhi)(zhi)又(you)被叫做乙烯基樹脂(zhi)(zhi). 物化(hua)性質(zhi)
環氧樹脂和含雙鍵的不飽和一元羧酸酌加成聚合物(wu).以苯乙烯(xi)為稀釋劑和交(jiao)聯劑.樹(shu)脂(zhi)兼具不飽和聚酯和環氧樹(shu)脂(zhi)的性能,有(you)良(liang)好的力學(xue)性能、韌(ren)性、耐熱性和黏結性,優(you)異的耐化學(xue)性及(ji)便于固化的特性.
