Inorganic silicate waterproof agent with depth permeability and filling property and preparation method of waterproof agent

Abstract

The invention belongs to the field of building materials, particularly relates to an inorganic silicate waterproof agent with depth permeability and filling property and a preparation method of the waterproof agent, and aims to provide a concrete waterproof agent with the depth permeability, excellent filling property and excellent waterproof performance. Soluble sodium silicate water solution serves as a reaction active substance, deionized water serves as a thinning agent, inert silica solution serves as a filling substance, and a catalyst and an ultra-high active fluorocarbon surfactant serves as auxiliary materials. The concrete waterproof agent has high active substance contents, appropriate inert fillers, medium viscosity and low surface tension, so that the concrete waterproof agent is high in permeation capacity and micro-pore filling capacity and can furthest close concrete surfaces, inner micro pores and micro cracks. When the waterproof agent is used, concrete and cement mortar surfaces are treated in a spraying manner, and the pressure-resistant strength and the anti-permeability performance of the waterproof agent can be remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of waterproofing materials for buildings, and in particular relates to an inorganic silicate waterproofing agent with deep permeability and filling property and a preparation method thereof. Background technique [0002] Concrete is essentially a porous substance, and micropores and microcracks inevitably exist on its surface. These structural imperfections provide pathways for moisture 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 further increase the water permeability of concrete. The water seepage of the concrete structure not only causes the building to leak, but also brings great inconvenience to the work and life of the people in the building. The greater harm is that the water seepage will cause the degradation of the perf...

Problems solved by technology

[0004] Based on the demand for rigid waterproofing of buildings, the present invention aims to provide a deeply permeable and filling inorganic silicate waterproofing agent and a preparation method thereof, so as to solve the problems of sodium silicate aqueous solution and catalyst of existing inorganic osmotic crystalline waterproofing agents. The poor match between the four, the inert material and the diluent makes it difficult to make the viscosity, surface tension and gelation time of the waterproofing agent reach the optimal value at the same time; at the same time, it is difficult to solve the surfactant in the prior art Reducing the surface tension of the waterproofing agent to a standard requirement below 36 mN / m, technical issues affecting the permeability of the waterproofing agent
