環(huan)(huan)氧樹脂通過(guo)不同的(de)水(shui)(shui)性(xing)化途徑可(ke)形(xing)成(cheng)三種水(shui)(shui)分散(san)形(xing)態：①水(shui)(shui)溶(rong)性(xing)；②膠束分散(san)型(xing)；③乳液。 環(huan)(huan)氧樹脂自(zi)身為(wei)(wei)熱塑性(xing)的(de)線型(xing)結構，受(shou)熱后固態變(bian)為(wei)(wei)液態，高粘(zhan)度(du)變(bian)為(wei)(wei)低粘(zhan)度(du)，只有(you)與固化劑配合使用才具(ju)有(you)實用價值(zhi) （純正的(de)單組分水(shui)(shui)性(xing)環(huan)(huan)氧體系也需加入(ru)潛伏(fu)型(xing)固化劑）。因此水(shui)(shui)性(xing)環(huan)(huan)氧體系應包含水(shui)(shui)性(xing)環(huan)(huan)氧樹脂和水(shui)(shui)性(xing)環(huan)(huan)氧固化劑，同樣，它...
