Abstract

In this paper, an inorganic-organic hybrid PAMgA/SiO2/K/GCC composite waterproof material was prepared by free radical polymerization using polymagnesium acrylate (PAMgA) as the substrate for the composite waterproof material. Silica (SiO2), Kaolin (K), and Ground calcium carbonate (GCC) were used as inorganic modified fillers. The response surface methodology (RSM) Box-Behnken design (BBD) was utilized to optimize the effect of the addition of an inorganic modified filler on the tensile strength of composite waterproof materials. The optimal ratios of SiO2, K, and GCC in the composite waterproof materials were obtained. When the additions of SiO2 was 6.776 wt %, K was 14.594 wt %, and GCC was 10.494 wt %, the tensile strength of PAMgA/SiO2/K/GCC composite waterproofing materials was experimentally measured to be as high as 1.679 MPa. The water retention rate (15 days) reached 82.8%, the swelling ratio (35 h) was 26%, and the coefficient of impermeability was as low as 1.169 × 10–8 cm/s. This composite waterproofing material exhibits a hybridized inorganic-organic structure, characterized by high tensile strength, effective water retention, swelling resistance, and seepage resistance. Its applications include its use as a sprayed membrane waterproofing material in underground engineering, where it demonstrates considerable promise.
