乙(yi)烯(xi)基(ji)酯樹(shu)(shu)(shu)(shu)脂(zhi)是由雙酚(fen)型或酚(fen)醛(quan)型環(huan)氧樹(shu)(shu)(shu)(shu)脂(zhi)與甲(jia)基(ji)丙(bing)烯(xi)酸(suan)反應得到的一類變性環(huan)氧樹(shu)(shu)(shu)(shu)脂(zhi),通常被稱為(wei)乙(yi)烯(xi)基(ji)酯樹(shu)(shu)(shu)(shu)脂(zhi)(VE),別名環(huan)氧丙(bing)烯(xi)酸(suan)樹(shu)(shu)(shu)(shu)脂(zhi),為(wei)熱固性樹(shu)(shu)(shu)(shu)脂(zhi).乙(yi)烯(xi)基(ji)酯樹(shu)(shu)(shu)(shu)脂(zhi)秉(bing)承(cheng)了環(huan)氧樹(shu)(shu)(shu)(shu)脂(zhi)的優良特性,固化性和成型性方(fang)面更為(wei)出色(se),能溶解于苯乙(yi)烯(xi)以(yi)及(ji)丙(bing)烯(xi)酸(suan)系單(dan)體.
乙烯基酯樹脂的介紹
乙(yi)烯(xi)基(ji)酯樹(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)是由(you)雙酚型(xing)(xing)或(huo)酚醛型(xing)(xing)環氧樹(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)與甲(jia)基(ji)丙(bing)烯(xi)酸反(fan)應得到的(de)一(yi)類變性(xing)(xing)環氧樹(shu)(shu)脂(zhi)(zhi)(zhi)(zhi),通常被稱(cheng)為(wei)乙(yi)烯(xi)基(ji)酯樹(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)(VE),別名環氧丙(bing)烯(xi)酸樹(shu)(shu)脂(zhi)(zhi)(zhi)(zhi),為(wei)熱固(gu)性(xing)(xing)樹(shu)(shu)脂(zhi)(zhi)(zhi)(zhi).乙(yi)烯(xi)基(ji)酯樹(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)秉承了(le)環氧樹(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)的(de)優良(liang)特性(xing)(xing),固(gu)化(hua)(hua)性(xing)(xing)和(he)成(cheng)型(xing)(xing)性(xing)(xing)方面更(geng)為(wei)出色,能(neng)溶(rong)解于(yu)苯乙(yi)烯(xi)以及丙(bing)烯(xi)酸系單體,由(you)于(yu)兼具環氧和(he)不飽(bao)和(he)的(de)優點,其應用領域正在不斷擴大.乙(yi)烯(xi)基(ji)酯樹(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)是由(you)環氧樹(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)與甲(jia)基(ji)丙(bing)烯(xi)酸通過開環加成(cheng)化(hua)(hua)學(xue)反(fan)應而(er)制得.它(ta)保留(liu)了(le)環氧樹(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)的(de)基(ji)本鏈段,又有不飽(bao)和(he)聚(ju)酯樹(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)的(de)良(liang)好工藝性(xing)(xing)能(neng),它(ta)在適宜條(tiao)件下(xia)固(gu)化(hua)(hua)后,表現出某些特殊的(de)優良(liang)性(xing)(xing)能(neng).
乙烯基樹脂的應用
1、 制作耐(nai)(nai)腐(fu)蝕(shi)FRP制品,如(ru)玻(bo)璃鋼槽罐(guan)、管道(dao)、塔器以及耐(nai)(nai)腐(fu)蝕(shi)格柵等.
2、 防腐蝕(shi)(shi)工程,如水泥基或鐵基玻璃(li)鋼(gang)襯里、高(gao)耐腐蝕(shi)(shi)地坪,高(gao)強度FRP制品,如玻璃(li)鋼(gang)型材、體育用品、FRP船艇等.
3、 重防(fang)腐玻璃(li)鱗片(pian)涂料、鱗片(pian)膠泥.
