Problems solved by technology

However, the waterproof performance and price of the same type of sodium silicate aqueous solution-based waterproofing materials vary greatly due to different formulations. Depending on the surface tension, viscosity and gelation time, the resulting water repellents also vary in their ability to penetrate and seal pores and microcracks in concrete
[0004] The existing sodium silicate-based sprayable inorganic gel concrete waterproofing agent has complex preparation process and high price, because the surface tension cannot be reduced to the optimal value by using ordinary anionic, cationic and amphoteric surfactants, so that it cannot be waterproofed best performance

Embodiment 1

[0029] A permeate multifunction water repellent and a preparation method thereof, wherein the penetrating multifunction water repellent consists of 8500-9500 parts of a methyl silicate aqueous solution, 30-60 parts of a catalyst, surfactant 4 -9 copies, 40-120 copies of preservatives, 100-350 water. Among them, the catalyst is a zinc-borne composite catalyst, the surfactant is a silicone surfactant, the preservatives being aqueous coating sterilization preservative.

[0030] Among them, 9400 sodium methyl silicate solution, 50 catalysts, 5 surfactants, 100 cases of preservative, and 445 water.

[0031] The aqueous sodium methyl silicate solution in the present invention is a commercially available finished colorless transparent liquid, or a 12-fold water formation of 27% sodium silicate solution is also used, and the sodium methyl silicate solution impurity content can be used. Low, prepared water repellent colorless transparency, low cost. The aqueous solution of sodium silicate ...

Embodiment 2

[0052] Example 2 is substantially identical to the technical solution of Example 1, there is different in that the permeate multifunction water repellent in Example 2 consists of 9000 parts of the sodium methyl silicate, zinc compound. 40 copies of the catalyst, 8 silicon surfactants, 52 parts of aqueous coating, 900 parts of water.

[0053] This embodiment also provides a method of penetrating multi-function water repellent, including the following steps:

[0054] Step 1, prepare the components according to the requirements;

[0055] Step 2, aqueous sodium methyl silicate and water were added to the reactor, mixed with stirring at the stirring rotational speed 800r / min, mixed 10 min, and mixture A;

[0056] Step three, add catalyst, surfactant, and preservative to mixture A;

[0057] Step 4, stirred at a stirred speed of 1000r / min to stir the dispersion for 30 min to obtain a permeable multifunction water repellent;

[0058] Step 5. Dispelling.

Embodiment 3

[0060] Example 3 is substantially identical to the technical solution of the first embodiment, and it is different from: 30 parts of the catalyst, 4 silicon surfactants, 40 parts of aqueous coating, 350 parts of water.

Abstract

The invention discloses a permeable multifunctional waterproof agent and a preparation method thereof, and belongs to the technical field of building waterproof materials, and the permeable multifunctional waterproof agent is prepared from a sodium methyl silicate aqueous solution, a zinc-bismuth composite catalyst, an organosilicon surfactant, a water-based paint bactericidal preservative and water. The permeable multifunctional waterproof agent has the advantages of simple preparation process and low cost, and the surface tension of the permeable multifunctional waterproof agent is reduced to the minimum value, so that the waterproof performance of the permeable multifunctional waterproof agent is optimal.

Description

Technical field [0001] The present invention belongs to the technical field of building waterproof material, and is specifically involved in a permeable multifunctional water repellent and a preparation method thereof. Background technique [0002] Water and water-soluble carbon dioxide, chloride, sulfur dioxide, and sulfate, etc., after entering concrete, it will corrode the steel bars in the concrete, resulting in reinforcing the degradation of reinforced steel performance in the concrete, affecting the service life of the building. Degradation of concrete performance due to the above causes has become a problem that must face all over the world, and a large number of resources are consumed by the repair of leakage buildings. The cost of repairing the required cost is sometimes more than the initial construction investment. In my country, the leakage of buildings is especially amazing and severe. It is a problem that plagues in my country's construction industry, and is also an...
