Description

technical field [0001] The invention relates to the technical field of polymer cement-based materials, in particular to a waterproof mortar and a preparation method thereof. Background technique [0002] At present, with the development of polymer cement-based materials, polymer cement waterproof mortar has been widely used in many projects. Good and many other advantages, with the gradual application of various recycled materials, the research on the product formulation of related polymer cement waterproof mortars is also gradually deepening, but at present, various polymer cement waterproof mortars using recycled materials still have compression resistance in the market. The problems of reduced flexural strength and viscosity, high bleeding and long setting time limit the further application of polymer cement waterproof mortars in polymer cement-based materials. SUMMARY OF THE INVENTION [0003] Based on this, it is necessary to provide a waterproof mortar, which aims t...
