preparation example Construction

[0061] On the other hand, the embodiment of the present application provides a preparation method, which specifically includes the following steps:

[0062] S100, prepare raw materials according to the components and their contents contained in the above-mentioned composite waterproofing agent;

[0063] S200, filter and magnetize the water and heat it, add the remaining components in the composite water repellent to the water, heat again to 100°C to 120°C, and stir at a constant temperature for 40 to 60 minutes;

[0064] The magnetization of water filtration increases the internal energy of water, promotes the change of water molecules, and changes the macromolecular water into small molecular water, which is easier to absorb; the filtered and magnetized water is heated, and heating can improve the remaining components in the composite waterproofing agent. In order to facilitate the operation of the operator and prevent scalding, the heating temperature can be set to 10-20 °C ...

Embodiment 1

[0074] A kind of composite waterproofing agent and its preparation method and application

[0075] The composite water repellent includes the following components by mass percentage: 6% of potassium aluminum sulfate, 1% of sodium silicate with a modulus of 2, 1% of silicon dioxide, 3% of methylcellulose, 0.26% of talc and chlorinated Sodium 1%, the balance is water.

[0076] The above-mentioned composite waterproofing agent is prepared by the following preparation method:

[0077] Prepare raw materials according to the components and their contents contained in the composite waterproofing agent described above;

[0078] After the water is magnetized by filtration, it is added to the reactor and heated to 10-20°C;

[0079] Add potassium aluminum sulfate, sodium silicate, methyl cellulose, sodium chloride, urea and filler in turn, heat up to 100°C, and keep stirring at 100°C for 1 hour;

[0080] Drop to room temperature for 1 hour and configure it as a composite waterproofing...

Abstract

The present application discloses a composite waterproofing agent and a preparation method and application thereof, including the following components by mass percentage: potassium aluminum sulfate 6%-20%, sodium silicate 1%-6%, sodium chloride 1%- 6%, urea 0.5%~3%, water retention agent 3%~8%, filler 1.26%~5.6%, the balance is water; the aluminum potassium sulfate is used as the main component of the composite waterproofing agent to form stable crystals with cement It can enhance the compactness and strength of the cement mortar to achieve self-waterproofing of the structure, and through the control of the type and content of the components, the components can play a synergistic effect, thereby further improving the anti-seepage of the composite waterproofing agent. leak function.

Description

technical field [0001] The application belongs to the technical field of construction engineering, and specifically relates to a composite waterproofing agent and a preparation method and application thereof. Background technique [0002] The rapid development of the construction industry plays an important role in the development of the national economy, but the leakage of construction projects has not been effectively solved. Once the leakage problem of the building occurs, its structural safety and durability may be involved. [0003] At present, the materials used in building anti-leakage are mainly surface water-retaining composite waterproofing agent and structural self-waterproofing composite waterproofing agent. Surface water-retaining composite waterproofing agent is mainly asphalt, waterproof coating film and waterproof membrane, etc. The waterproofing agent cannot solve the alkali-aggregate reaction of the concrete itself; and the above-mentioned composite waterpr...
