Water-based capillary crystalline waterproofing agent

Abstract

The invention discloses a water-based capillary crystalline waterproofing agent. The agent is characterized by being prepared from the following components in parts by mass: 40-60 parts of an organicsilicon monomer, 6-9 parts of a surfactant, 6-9 parts of a polymer film-forming agent, 10-15 parts of nano silicon dioxide, 10-15 parts of amorphous calcium aluminate, 6-9 parts of calcium hydroxide and 50-70 parts of water. The waterproof agent has very strong permeability and can permeate below the surface layer of concrete by 3-8 cm, formed eutectic always grows along capillary pores of the concrete, all pores of the concrete are blocked, the compactness of the concrete can be enhanced, the strength and hardness of a concrete base material can also be enhanced, and the waterproof effect with the same service life as the concrete is achieved, according to the invention, the plasticization of concrete and mortar can be improved, and the weathering resistance, shrinkage resistance and impermeable pressure of concrete are further improved,construction is easy, and cost is low.

Description

technical field [0001] The invention relates to a crystalline waterproofing agent, in particular to a osmotic crystalline waterproofing agent. Background technique [0002] With the continuous development of China's engineering construction, corresponding housing and ground water seepage problems are also emerging one after another. The demand for waterproof materials is also increasing. At present, the types of waterproof materials in our country are complex, and the waterproof technology is constantly updated. There are 5 categories of waterproof materials: waterproof coiled materials, waterproof coatings, and plugging materials. [0003] Cement-based permeable crystalline waterproof coating is a slurry material with inorganic cementitious materials as the main component, mixed with active chemical substances and a certain amount of mixed materials, mixed with water and stirred evenly, and then brushed or sprayed on the surface of the substrate. It can also be directly ...

Problems solved by technology

In this solution, sodium fluoride dissolves in water and is weakly alkaline, and has poor compatibility with tartaric acid and silica sol, which is not conducive to the long-term stability of the waterproofing agent.
