水(shui)性環氧地坪的優勢

水(shui)性環氧樹脂以(yi)其(qi)突(tu)出的(de)性能優(you)勢(shi)，使制備得到的(de)水(shui)性環氧樹脂涂料(liao)同樣具有優(you)異的(de)性能，從而在(zai)水(shui)性產品大家族里地位越來越重(zhong)要，專家認為水(shui)性環氧樹脂在(zai)環保(bao)化的(de)今(jin)天，前景十分開闊。

水(shui)性(xing)(xing)環(huan)(huan)氧樹(shu)(shu)(shu)脂(zhi)(zhi)(zhi)是(shi)指環(huan)(huan)氧樹(shu)(shu)(shu)脂(zhi)(zhi)(zhi)以(yi)(yi)微(wei)粒或(huo)液滴的(de)(de)形式分散在以(yi)(yi)水(shui)為連(lian)續相的(de)(de)分散介(jie)質(zhi)(zhi)中而配(pei)得(de)的(de)(de)穩定分散體系(xi)。由于環(huan)(huan)氧樹(shu)(shu)(shu)脂(zhi)(zhi)(zhi)是(shi)線型結構的(de)(de)熱固(gu)性(xing)(xing)樹(shu)(shu)(shu)脂(zhi)(zhi)(zhi)，所以(yi)(yi)施(shi)工(gong)前(qian)必(bi)須加(jia)入水(shui)性(xing)(xing)環(huan)(huan)氧固(gu)化(hua)劑，在室溫(wen)環(huan)(huan)境下發生(sheng)化(hua)學交聯(lian)反應，環(huan)(huan)氧樹(shu)(shu)(shu)脂(zhi)(zhi)(zhi)固(gu)化(hua)后(hou)就改變了原來可(ke)溶可(ke)熔的(de)(de)性(xing)(xing)質(zhi)(zhi)而變成不(bu)溶不(bu)熔的(de)(de)空間網狀結構，顯示出優(you)(you)異(yi)(yi)的(de)(de)性(xing)(xing)能(neng)(neng)。水(shui)性(xing)(xing)環(huan)(huan)氧樹(shu)(shu)(shu)脂(zhi)(zhi)(zhi)涂(tu)(tu)料(liao)除了具(ju)有(you)(you)(you)(you)溶劑型環(huan)(huan)氧樹(shu)(shu)(shu)脂(zhi)(zhi)(zhi)涂(tu)(tu)料(liao)的(de)(de)諸多優(you)(you)點，一是(shi)適應能(neng)(neng)力強(qiang)，對眾多底材具(ju)有(you)(you)(you)(you)極(ji)高(gao)(gao)的(de)(de)附著力，固(gu)化(hua)后(hou)的(de)(de)涂(tu)(tu)膜耐腐蝕性(xing)(xing)和(he)耐化(hua)學藥(yao)品性(xing)(xing)能(neng)(neng)優(you)(you)異(yi)(yi)，并且涂(tu)(tu)膜收縮小、硬(ying)度(du)高(gao)(gao)、耐磨性(xing)(xing)好、電(dian)氣絕緣性(xing)(xing)能(neng)(neng)優(you)(you)異(yi)(yi)等(deng)；二(er)是(shi)環(huan)(huan)保性(xing)(xing)能(neng)(neng)好，還具(ju)有(you)(you)(you)(you)不(bu)含有(you)(you)(you)(you)機(ji)溶劑或(huo)揮發性(xing)(xing)有(you)(you)(you)(you)機(ji)化(hua)合物含量(liang)較低(di)，不(bu)會(hui)造成空氣污染，因而滿足當前(qian)環(huan)(huan)境保護的(de)(de)要求；三是(shi)真正(zheng)水(shui)性(xing)(xing)化(hua)，以(yi)(yi)水(shui)作為分散介(jie)質(zhi)(zhi)，價格低(di)廉、無(wu)氣味(wei)、不(bu)燃，儲存、運(yun)輸和(he)使用過程中的(de)(de)安全性(xing)(xing)也大為提高(gao)(gao)；四是(shi)操(cao)作性(xing)(xing)佳(jia)，水(shui)性(xing)(xing)環(huan)(huan)氧樹(shu)(shu)(shu)脂(zhi)(zhi)(zhi)涂(tu)(tu)料(liao)的(de)(de)施(shi)工(gong)操(cao)作性(xing)(xing)能(neng)(neng)好，施(shi)工(gong)工(gong)具(ju)可(ke)用水(shui)直接清洗，可(ke)在室溫(wen)和(he)潮濕的(de)(de)環(huan)(huan)境中固(gu)化(hua)，有(you)(you)(you)(you)合理(li)的(de)(de)固(gu)化(hua)時間，并保證有(you)(you)(you)(you)很高(gao)(gao)的(de)(de)交聯(lian)密度(du)。這是(shi)通常的(de)(de)水(shui)性(xing)(xing)丙烯酸涂(tu)(tu)料(liao)和(he)水(shui)性(xing)(xing)聚氨(an)酯涂(tu)(tu)料(liao)所無(wu)法(fa)比擬的(de)(de)。
