Abstract

The invention relates to water seepage prevention cement which is prepared from the following raw materials in percentage by weight: 5%-8% of fluorine-containing polyacrylate latex powder, 2%-3% of rosin of 100-200 meshes, 3%-5% of sodium silicate, 3%-5% of calcium hydroxide, 1%-2% of alums, 1%-2% of sodium dodecyl sulfate, 10%-15% of sulphate aluminum cement and the balance of silicate cement, wherein the fluorine content of the fluorine-containing polyacrylate latex powder is 1%-3%. The water seepage prevention cement prepared by the invention has water seepage prevention function.

Description

technical field [0001] The invention belongs to the technical field of polymer cement material research, and in particular relates to an anti-seepage cement. Background technique [0002] Through microscopic analysis, it can be known that cement will form four types of pores in the matrix during the hydration process: gel pores, transition pores, capillary pores and macropores. The total porosity of these pores, the distribution of pore diameters, the size and shape of the pores will all affect the compressive and flexural strength of the matrix. General cement-based composite materials are mainly composed of unhydrated cement clinker particles, hydrated crystalline minerals and gels of cement, water and a small amount of air. It is a solid-liquid-gas multiphase porous body. Therefore, buildings made of ordinary cement are bound to seep water. Therefore, it is necessary to lay a waterproof layer on the upper or lower layer of the cement product. In this way, the project c...
