Abstract

A method for preparing a novel waterproof cement material comprises the following steps: firstly, adding quartz sand and sodium silicate into a reaction kettle, and performing heating to raise the temperature to 150-180 DEG C to remove water; secondly, grinding quartz sand and sodium silicate to ensure that the grain fineness reaches 100-150 [mu]m; thirdly, adding a modified ethyl methacrylate emulsion into quartz sand and sodium silicate, continually raising the temperature to 200-250 DEG C, and performing uniform stirring to produce a mixture I; fourthly, adding ammonium polyacrylate, silicone oil, a flatting agent and a wetting agent into the mixture I, controlling the temperature to be 80-90 DEG C, and performing stirring till all components are completely dissolved and mixed to obtain a mixture II; and fifthly, adding high-temperature resin and tackifying resin into the mixture II, performing stirring for dissolution, then adding nano talcum powder, heavy calcium carbonate and ordinary Portland cement, performing heating and uniform stirring, and then conducting cooling. The prepared cement is favorable in waterproofness, the preparation method is simple, the material cost is low, and the method is suitable for industrial large-scale production.

Description

technical field [0001] The invention belongs to the technical field of waterproof materials, and in particular relates to a preparation method of a novel waterproof cement material. Background technique [0002] Concrete is the most commonly used building material in modern architecture. Since concrete is a porous material in nature, micropores and microcracks inevitably exist on its surface. These structural imperfections provide pathways for water molecules to seep into the interior of the concrete. In addition, the shrinkage cracks produced by the evaporation of water on the surface of concrete in the plastic stage and the temperature cracks produced in the hardening stage will also increase the water permeability of concrete. Waterproof materials can effectively prevent the penetration of water in concrete and greatly improve the durability of concrete. [0003] At present, there are two main types of waterproof materials: one is polyurethane waterproof coating, which ...
