防腐蝕工程
乙烯基酯樹脂是由雙酚型或酚醛型環氧樹脂與甲(jia)基丙烯(xi)(xi)酸(suan)反應得(de)到的(de)一(yi)類變性環(huan)氧(yang)樹(shu)(shu)脂(zhi)(zhi),通常(chang)被稱(cheng)為(wei)(wei)乙烯(xi)(xi)基酯樹(shu)(shu)脂(zhi)(zhi)(VE),別(bie)名(ming)環(huan)氧(yang)丙烯(xi)(xi)酸(suan)樹(shu)(shu)脂(zhi)(zhi),為(wei)(wei)熱固(gu)性樹(shu)(shu)脂(zhi)(zhi).乙烯(xi)(xi)基酯樹(shu)(shu)脂(zhi)(zhi)秉(bing)承了環(huan)氧(yang)樹(shu)(shu)脂(zhi)(zhi)的(de)優良(liang)特性,固(gu)化性和成型(xing)性方面更為(wei)(wei)出(chu)色,能溶解(jie)于苯乙烯(xi)(xi)以及(ji)丙烯(xi)(xi)酸(suan)系單體.
乙烯基酯樹脂的介紹
乙烯(xi)(xi)基(ji)(ji)(ji)酯樹(shu)脂(zhi)(zhi)(zhi)是由(you)雙酚(fen)(fen)型(xing)或酚(fen)(fen)醛型(xing)環氧(yang)(yang)樹(shu)脂(zhi)(zhi)(zhi)與甲基(ji)(ji)(ji)丙烯(xi)(xi)酸反應得(de)到的(de)(de)一類變性(xing)環氧(yang)(yang)樹(shu)脂(zhi)(zhi)(zhi),通(tong)常被(bei)稱為乙烯(xi)(xi)基(ji)(ji)(ji)酯樹(shu)脂(zhi)(zhi)(zhi)(VE),別名環氧(yang)(yang)丙烯(xi)(xi)酸樹(shu)脂(zhi)(zhi)(zhi),為熱(re)固性(xing)樹(shu)脂(zhi)(zhi)(zhi).乙烯(xi)(xi)基(ji)(ji)(ji)酯樹(shu)脂(zhi)(zhi)(zhi)秉(bing)承(cheng)了環氧(yang)(yang)樹(shu)脂(zhi)(zhi)(zhi)的(de)(de)優(you)良特性(xing),固化(hua)(hua)性(xing)和成型(xing)性(xing)方(fang)面(mian)更為出色,能(neng)(neng)溶解于苯乙烯(xi)(xi)以及丙烯(xi)(xi)酸系單(dan)體,由(you)于兼具環氧(yang)(yang)和不(bu)飽(bao)和的(de)(de)優(you)點(dian),其應用領域正在不(bu)斷擴大(da).乙烯(xi)(xi)基(ji)(ji)(ji)酯樹(shu)脂(zhi)(zhi)(zhi)是由(you)環氧(yang)(yang)樹(shu)脂(zhi)(zhi)(zhi)與甲基(ji)(ji)(ji)丙烯(xi)(xi)酸通(tong)過開(kai)環加(jia)成化(hua)(hua)學(xue)反應而制得(de).它保留了環氧(yang)(yang)樹(shu)脂(zhi)(zhi)(zhi)的(de)(de)基(ji)(ji)(ji)本鏈段,又有不(bu)飽(bao)和聚酯樹(shu)脂(zhi)(zhi)(zhi)的(de)(de)良好工藝性(xing)能(neng)(neng),它在適宜(yi)條(tiao)件(jian)下固化(hua)(hua)后,表現出某些特殊的(de)(de)優(you)良性(xing)能(neng)(neng).
乙烯基樹脂的應用
1、 制(zhi)作耐腐(fu)蝕FRP制(zhi)品(pin),如玻璃(li)鋼槽罐、管道、塔器以及耐腐(fu)蝕格柵等.
2、 防腐蝕(shi)工程,如水泥基或鐵(tie)基玻璃(li)鋼襯(chen)里、高耐腐蝕(shi)地(di)坪,高強度FRP制品(pin)(pin),如玻璃(li)鋼型材、體(ti)育用品(pin)(pin)、FRP船艇等.
3、 重防(fang)腐(fu)玻璃鱗片(pian)涂料、鱗片(pian)膠泥.
4、 -如(ru)UV油墨、重防腐工(gong)業地坪(ping)等.
5、 電廠脫硫防(fang)腐(fu),耐(nai)高(gao)溫,耐(nai)強酸強堿.
乙(yi)烯(xi)基酯樹(shu)脂又(you)被叫做乙(yi)烯(xi)基樹(shu)脂. 物化性質
環氧樹脂和含雙鍵的不飽和一元羧酸酌加成聚合物.以苯乙烯為(wei)稀釋劑(ji)和交聯(lian)劑(ji).樹脂(zhi)兼具(ju)不飽和聚酯和環(huan)氧樹脂(zhi)的(de)性(xing)(xing)(xing)能,有良(liang)好(hao)的(de)力學(xue)性(xing)(xing)(xing)能、韌性(xing)(xing)(xing)、耐熱性(xing)(xing)(xing)和黏結性(xing)(xing)(xing),優異的(de)耐化(hua)學(xue)性(xing)(xing)(xing)及(ji)便于固化(hua)的(de)特性(xing)(xing)(xing).
