一种可广泛应用于水利、建筑等工程建设的高效防水防渗材料——双组份聚硫防水密封膏日前在河北衡水华鑫橡塑有限公司研制成功。该产品填补了国内空白,并申报了国家技术专利。双组份聚硫防水密封膏具有良好的耐久性、气密性和防水性,且无毒无害,对环境无污染。特别是在混凝土、钢筋等粘接中,其拉伸粘接性最大拉伸强度达0.87MPa,最大伸长率不小于273％,下垂度不大于3毫米,使用寿命达60年以上。
A widely used in water conservancy, construction and other construction projects efficient waterproof impermeable material - two-component polysulfide waterproof sealant recently in Hebei Hengshui Huaxin Rubber Co., Ltd. successfully developed. The product has filled the gaps in the country, and declared a national technology patents. Two-component polysulfide waterproof sealant with good durability, air tightness and water resistance, and non-toxic harmless to the environment without pollution. Especially in concrete, steel and other bonding, the tensile adhesive tensile strength of the maximum tensile 0.87MPa, the maximum elongation of not less than 273%, sag less than 3 mm, the service life of 60 years.
