Embodiment Construction
[0019] In order to disclose more clearly, the present invention is described from several aspects below.
[0020] For waterproof plugging materials, from a mechanism point of view, the three most important indicators are: setting time, strength, and impermeability (expansion rate). Only by meeting the requirements of these three indicators can we get good results in engineering.
[0021] The self-waterproof high-performance quick-acting plugging agent provided by the present invention is based on sulphoaluminate cement (including iron-aluminate cement) and aluminum materials that meet the current standard requirements, adding appropriate amount of gypsum, micro-expansion components, coagulation The time adjusting agent, hardening agent, plasticizer, adhesive and other materials for improving the performance of waterproof and leak-proofing are prepared together, so that the above-mentioned performance of the material is obviously better than that of the existing waterproof and ...
