乙烯基酯樹脂的介紹
乙(yi)烯(xi)(xi)基酯(zhi)樹(shu)脂(zhi)是由雙酚(fen)型(xing)或酚(fen)醛型(xing)環(huan)(huan)氧樹(shu)脂(zhi)與甲基丙烯(xi)(xi)酸反應得(de)到的(de)一類變(bian)性(xing)(xing)環(huan)(huan)氧樹(shu)脂(zhi),通常被稱為乙(yi)烯(xi)(xi)基酯(zhi)樹(shu)脂(zhi)(VE),別名環(huan)(huan)氧丙烯(xi)(xi)酸樹(shu)脂(zhi),為熱固(gu)(gu)性(xing)(xing)樹(shu)脂(zhi).乙(yi)烯(xi)(xi)基酯(zhi)樹(shu)脂(zhi)秉承了(le)環(huan)(huan)氧樹(shu)脂(zhi)的(de)優良(liang)特(te)性(xing)(xing),固(gu)(gu)化(hua)性(xing)(xing)和(he)成(cheng)型(xing)性(xing)(xing)方面(mian)更為出(chu)色,能溶解于苯乙(yi)烯(xi)(xi)以(yi)及丙烯(xi)(xi)酸系單(dan)體,由于兼具環(huan)(huan)氧和(he)不(bu)飽(bao)和(he)的(de)優點,其應用領(ling)域(yu)正(zheng)在不(bu)斷擴大.乙(yi)烯(xi)(xi)基酯(zhi)樹(shu)脂(zhi)是由環(huan)(huan)氧樹(shu)脂(zhi)與甲基丙烯(xi)(xi)酸通過開環(huan)(huan)加成(cheng)化(hua)學反應而制(zhi)得(de).它(ta)(ta)保留了(le)環(huan)(huan)氧樹(shu)脂(zhi)的(de)基本(ben)鏈段,又有不(bu)飽(bao)和(he)聚酯(zhi)樹(shu)脂(zhi)的(de)良(liang)好工藝(yi)性(xing)(xing)能,它(ta)(ta)在適宜條(tiao)件(jian)下固(gu)(gu)化(hua)后,表(biao)現出(chu)某(mou)些(xie)特(te)殊的(de)優良(liang)性(xing)(xing)能.
乙烯基樹脂的應用
1、 制作耐腐蝕(shi)FRP制品,如玻璃鋼槽罐、管道、塔器(qi)以及(ji)耐腐蝕(shi)格柵(zha)等.
2、 防腐蝕工程,如水泥基或鐵基玻璃鋼襯里、高耐腐蝕地坪,高強度FRP制(zhi)品,如玻璃鋼型材(cai)、體育用品、FRP船艇等.
3、 重防腐玻璃鱗片(pian)涂料(liao)、鱗片(pian)膠泥.
4、 -如(ru)UV油墨(mo)、重防腐工業(ye)地坪(ping)等.
5、 電廠脫硫(liu)防腐(fu),耐高溫,耐強酸(suan)強堿(jian).
乙烯基(ji)酯(zhi)樹脂又被叫做(zuo)乙烯基(ji)樹脂. 物化性質
環氧樹脂和含雙鍵的不飽和一元羧酸酌加(jia)成聚合物.以苯(ben)乙烯為稀釋劑和(he)交聯(lian)劑.樹脂兼具不飽和(he)聚酯和(he)環氧樹脂的性能,有(you)良好的力學(xue)(xue)性能、韌性、耐熱性和(he)黏結性,優異的耐化學(xue)(xue)性及便于固化的特性.
