环氧煤焦油防渗涂料系由环氧树脂、煤焦油为主剂,外加一定量邻苯二甲酸二丁脂、甲苯(或二甲苯)、乙二胺(或二乙稀三胺)等辅助化学药剂配制而成,外观为黑褐色粘稠液体,具有粘结力强,物理机械性能好,抗渗性佳及耐腐蚀等特点。它在水利水电工程中已较多的用于水工混凝土建筑物和钢丝网水泥构件表面防腐,也有用作砌石拱坝坝体的防渗,均已获得良好的效果。我所曾在七九年间,针对环氧煤焦油作为混凝土结构物的防渗材料,就涂
Epoxy coal tar impermeable coating consists of epoxy resin, coal tar as the main agent, plus a certain amount of dibutyl phthalate, toluene (or xylene), ethylenediamine (or diethylenetriamine) and other auxiliary Formulated from chemical agents, the appearance of dark brown viscous liquid, with strong adhesion, good physical and mechanical properties, good impermeability and corrosion resistance and so on. It has been used in water conservancy and hydropower projects more for hydraulic concrete structures and wire mesh cement surface corrosion, but also for the masonry dam seepage control, have achieved good results. I have in 1979, for the anti-seepage material of epoxy coal tar concrete structure, Tu
