有机硅防水剂喷涂于各种建筑物表面,能渗透进基层,且不降低基层的透气性,具有憎水和透气的特点。与建筑涂料配套使用,可保持涂料鲜艳色彩,经久耐用。近年来,国产有机硅851防水剂(即甲基硅醇钠)已应用于建筑物上,具有防水效果,但其使用寿命不长;且碱性较强,喷涂时具有刺激性气体,会腐蚀皮肤。因此,急需开发新型防水剂产品。苏州市建筑科学研究所与上海树脂厂合作,共同开发新型有机硅 SAH—
Silicone waterproofing agent is sprayed on the surface of various buildings, can penetrate into the base layer, and does not reduce the permeability of the base layer, and has the characteristics of drowning and ventilation. Used in conjunction with architectural paints, it maintains bright colors and is durable. In recent years, the domestic silicone 851 water repellent (namely methyl sodium silanolate) has been applied to buildings and has a waterproof effect, but its service life is not long; its alkalinity is strong, and it has irritant gas when sprayed, and it will corrode. skin. Therefore, it is urgent to develop new water repellent products. The Suzhou Institute of Building Science cooperated with Shanghai Resin Factory to jointly develop a new type of silicone SAH—
