Abstract

The invention belongs to the technical field of building construction, and particularly relates to an environmentally friendly waterproof leakage stopping material and a preparation method thereof. The environmentally friendly waterproof leakage stopping material is prepared from the following raw materials in parts by weight: 50-100 parts of silicate, 10-35 parts of aluminate, 10-40 parts of redispersible rubber powder, 0.5-15 part of quartz sand, 5-20 parts of calcined gypsum powder, 1-10 parts of a retarder and 1-10 parts of an additive. The waterproof leakage stopping material which is prepared by the provided formula and the preparation method is environmentally friendly and toxic-free, and is high in bending resistance, high in impermeability pressure, high in wet base surface bonding strength and high in acid resistance.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to an environment-friendly waterproof plugging material, a preparation method and an application thereof. Background technique [0002] Water is a pervasive substance, no matter how hard the building is, it will also suffer from water seepage, so waterproofing is one of the necessary steps in the construction process. Once water penetrates into the building, in a limited space, under the condition of receiving thermal energy such as solar heat, the water turns into water vapor, and the pressure generated by the water vapor is very likely to destroy the original waterproof layer and even destroy the building. Surface finishes, such as causing paint peeling and wood floors to bulge. Furthermore, when the building is built, due to the age of the building or the uneven settlement of the building, etc., there will often be cracks, etc., resulting in water leaka...
