乙烯基酯樹脂的介紹
乙(yi)烯(xi)基酯(zhi)樹(shu)(shu)(shu)(shu)(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)是由(you)雙(shuang)酚型(xing)(xing)或酚醛型(xing)(xing)環(huan)氧(yang)樹(shu)(shu)(shu)(shu)(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)與甲基丙(bing)烯(xi)酸(suan)(suan)(suan)反(fan)應得到的(de)(de)一類變性環(huan)氧(yang)樹(shu)(shu)(shu)(shu)(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)(zhi)(zhi),通常被稱(cheng)為(wei)乙(yi)烯(xi)基酯(zhi)樹(shu)(shu)(shu)(shu)(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(VE),別名環(huan)氧(yang)丙(bing)烯(xi)酸(suan)(suan)(suan)樹(shu)(shu)(shu)(shu)(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)(zhi)(zhi),為(wei)熱固性樹(shu)(shu)(shu)(shu)(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)(zhi)(zhi).乙(yi)烯(xi)基酯(zhi)樹(shu)(shu)(shu)(shu)(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)秉承了環(huan)氧(yang)樹(shu)(shu)(shu)(shu)(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)的(de)(de)優(you)良特(te)(te)性,固化(hua)性和(he)成型(xing)(xing)性方面更(geng)為(wei)出色,能溶解于苯乙(yi)烯(xi)以(yi)及丙(bing)烯(xi)酸(suan)(suan)(suan)系單體,由(you)于兼具環(huan)氧(yang)和(he)不飽(bao)和(he)的(de)(de)優(you)點,其應用領域正在(zai)不斷擴大.乙(yi)烯(xi)基酯(zhi)樹(shu)(shu)(shu)(shu)(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)是由(you)環(huan)氧(yang)樹(shu)(shu)(shu)(shu)(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)與甲基丙(bing)烯(xi)酸(suan)(suan)(suan)通過開(kai)環(huan)加成化(hua)學反(fan)應而制得.它(ta)保留了環(huan)氧(yang)樹(shu)(shu)(shu)(shu)(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)的(de)(de)基本鏈段,又有(you)不飽(bao)和(he)聚酯(zhi)樹(shu)(shu)(shu)(shu)(shu)(shu)脂(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)的(de)(de)良好工藝性能,它(ta)在(zai)適宜條件下(xia)固化(hua)后,表現出某些(xie)特(te)(te)殊(shu)的(de)(de)優(you)良性能.
乙烯基樹脂的應用
1、 制(zhi)(zhi)作耐(nai)腐蝕(shi)FRP制(zhi)(zhi)品,如玻璃鋼槽(cao)罐(guan)、管(guan)道、塔器以(yi)及耐(nai)腐蝕(shi)格(ge)柵等(deng).
2、 防腐蝕(shi)工程,如水泥基或(huo)鐵基玻璃(li)鋼(gang)襯里、高耐腐蝕(shi)地坪(ping),高強度FRP制品,如玻璃(li)鋼(gang)型材、體育用品、FRP船艇等.
3、 重防腐玻(bo)璃鱗(lin)片(pian)涂料、鱗(lin)片(pian)膠(jiao)泥(ni).
4、 -如UV油(you)墨、重防腐工(gong)業地坪(ping)等.
