Hydrophobic capillary crystalline waterproof agent and preparation method thereof

Abstract

The invention discloses a hydrophobic capillary crystalline waterproof agent and a preparation method thereof. The hydrophobic capillary crystalline waterproof agent is prepared from the following 11 raw materials: dodecylbenzene sulfonic acid, anhydrous isopropanol, nonylphenol peroxy vinyl ether, an aqueous sodium hydroxide solution, an aqueous sodium hypochlorite solution, an aqueous sodium silicate solution, tartrate, anhydrous sodium carbonate, a copolymerization solution of sodium acrylate and calcium acrylate, a sodium methylsilanolate solution and deionized water. The waterproof agent has the advantages of good waterproof performance, crack resistance, cleaning performance, no shrinkage, self-healing, hydraulic pressure resistance, surface hydrophobicity, capacity of preventing infiltration of steam and generation of mildew, etc.; moreover, the waterproof agent is simple and fast to construct, people with or without waterproof construction experience can rapidly master skills of waterproof construction with the agent, the agent is nontoxic and pollution-free in construction or application, etc.

Description

technical field [0001] The invention relates to a hydrophobic osmotic crystalline waterproofing agent and a preparation method thereof, belonging to the technical field of building waterproofing materials. Background technique [0002] At present, there are various degrees of water leakage in the exterior walls of many infrastructures and housing constructions in my country. The reasons for the leakage of the external walls of these buildings are more complicated, involving many factors such as design, materials, construction and management. According to the survey results, among the causes of water leakage in the above buildings, material factors accounted for 20%, design factors accounted for 26%, construction factors accounted for 48%, management and maintenance and objective factors accounted for 6%. With the improvement of my country's construction technology level and environmental protection requirements, great changes have taken place in the materials of exterior wa...

Problems solved by technology

Many years of practice at home and abroad have proved that although traditional elastic waterproof materials such as coatings have the characteristics of elasticity or flexibility, there is always a problem of "separation" from the base concrete. Humidity, water seepage and water channeling are always its enemies. At the same time, the material itself has poor corrosion resistance in a specific environment and cannot reach the normal service life

At present, all kinds of waterproofing agents used in building waterproofing have more or less the following problems or deficiencies: poor bonding strength with the base layer, erosion resistance, carbonization resistance, erosion resistance, frost resistance and durability, etc.

Therefore, the waterproof materials in the prior art are not ideal, and still cannot meet the requirements of use.
