乙烯基酯樹脂的介紹
乙(yi)烯(xi)(xi)(xi)基(ji)(ji)(ji)(ji)酯樹(shu)(shu)脂(zhi)(zhi)是由雙酚(fen)型(xing)或酚(fen)醛型(xing)環(huan)(huan)(huan)(huan)氧(yang)樹(shu)(shu)脂(zhi)(zhi)與甲基(ji)(ji)(ji)(ji)丙(bing)烯(xi)(xi)(xi)酸反應得到(dao)的(de)一類變性環(huan)(huan)(huan)(huan)氧(yang)樹(shu)(shu)脂(zhi)(zhi),通常被稱(cheng)為(wei)乙(yi)烯(xi)(xi)(xi)基(ji)(ji)(ji)(ji)酯樹(shu)(shu)脂(zhi)(zhi)(VE),別名環(huan)(huan)(huan)(huan)氧(yang)丙(bing)烯(xi)(xi)(xi)酸樹(shu)(shu)脂(zhi)(zhi),為(wei)熱固(gu)(gu)性樹(shu)(shu)脂(zhi)(zhi).乙(yi)烯(xi)(xi)(xi)基(ji)(ji)(ji)(ji)酯樹(shu)(shu)脂(zhi)(zhi)秉(bing)承了(le)環(huan)(huan)(huan)(huan)氧(yang)樹(shu)(shu)脂(zhi)(zhi)的(de)優良特性,固(gu)(gu)化(hua)性和(he)成(cheng)型(xing)性方(fang)面更為(wei)出色,能溶解于苯乙(yi)烯(xi)(xi)(xi)以(yi)及(ji)丙(bing)烯(xi)(xi)(xi)酸系單體,由于兼具環(huan)(huan)(huan)(huan)氧(yang)和(he)不(bu)(bu)飽和(he)的(de)優點(dian),其(qi)應用領域正在(zai)不(bu)(bu)斷擴(kuo)大.乙(yi)烯(xi)(xi)(xi)基(ji)(ji)(ji)(ji)酯樹(shu)(shu)脂(zhi)(zhi)是由環(huan)(huan)(huan)(huan)氧(yang)樹(shu)(shu)脂(zhi)(zhi)與甲基(ji)(ji)(ji)(ji)丙(bing)烯(xi)(xi)(xi)酸通過開(kai)環(huan)(huan)(huan)(huan)加成(cheng)化(hua)學反應而制得.它保留了(le)環(huan)(huan)(huan)(huan)氧(yang)樹(shu)(shu)脂(zhi)(zhi)的(de)基(ji)(ji)(ji)(ji)本鏈段,又(you)有不(bu)(bu)飽和(he)聚酯樹(shu)(shu)脂(zhi)(zhi)的(de)良好工藝性能,它在(zai)適(shi)宜條件下固(gu)(gu)化(hua)后,表現出某些特殊(shu)的(de)優良性能.
乙烯基樹脂的應用
1、 制作耐腐(fu)蝕(shi)FRP制品(pin),如(ru)玻璃鋼槽罐、管道、塔器(qi)以(yi)及(ji)耐腐(fu)蝕(shi)格(ge)柵(zha)等.
2、 防(fang)腐蝕工(gong)程,如水泥基或鐵基玻璃鋼(gang)襯里、高耐腐蝕地坪,高強度FRP制品,如玻璃鋼(gang)型材、體(ti)育用品、FRP船艇等.
3、 重防腐玻璃鱗(lin)片(pian)涂料(liao)、鱗(lin)片(pian)膠(jiao)泥.
4、 -如UV油墨、重防腐工業地(di)坪等.
5、 電(dian)廠脫(tuo)硫防腐,耐(nai)高溫,耐(nai)強酸(suan)強堿.
乙烯基酯樹脂又被叫做乙烯基樹脂. 物化性質
環氧樹脂和含雙鍵的不飽和一元羧酸(suan)酌加成聚合物.以苯乙(yi)烯為(wei)稀釋劑(ji)和(he)交聯劑(ji).樹脂(zhi)兼具不飽(bao)和(he)聚酯和(he)環氧樹脂(zhi)的性(xing)(xing)(xing)(xing)(xing)能,有良好的力(li)學性(xing)(xing)(xing)(xing)(xing)能、韌(ren)性(xing)(xing)(xing)(xing)(xing)、耐熱(re)性(xing)(xing)(xing)(xing)(xing)和(he)黏結(jie)性(xing)(xing)(xing)(xing)(xing),優異的耐化學性(xing)(xing)(xing)(xing)(xing)及便(bian)于固化的特性(xing)(xing)(xing)(xing)(xing).
