我单位在双曲线冷却水塔的筒壁及无保温钢筋混凝土屋面的防水层施工中,采用了四川成都橡胶厂生产的再生橡胶—沥青防水涂料(以下简称涂料),代替以往常用的沥青及两毡三油卷材防水和防潮层,取得了较好的效果。该涂料是以废橡胶、石油沥青和汽油为主要原料,经油法再生及研磨制浆等工艺制成.其特点是施工中不需要熬制和配料,成 In the construction of the wall of the hyperbolic cooling tower and the waterproof layer of the non-insulated reinforced concrete roof, the unit used the reclaimed rubber-asphalt waterproof coating (hereinafter referred to as coating) produced by Sichuan Chengdu Rubber Factory to replace the commonly used asphalt and felt. The three oil coil waterproof and moisture-proof layer achieved good results. The paint is made of waste rubber, petroleum pitch and gasoline as the main raw materials, and is made by the process of oil regeneration and grinding and pulping. It is characterized by the fact that no tanning and batching is required during construction.
