Aerosol type siloxane modified waterproof leak-repairing material and preparation method thereof

Abstract

The invention relates to the technical field of waterproof and leak-repairing materials, and discloses an aerosol type siloxane modified waterproof and leak-repairing material and a preparation method thereof.The aerosol type siloxane modified waterproof and leak-repairing material is prepared from, by weight, 40-50 parts of siloxane modified waterborne polyurethane resin, 20-40 parts of deionized water, 10-20 parts of silane impregnant, 1-2 parts of propylene glycol, 1-2 parts of coalescing agent, 0.2-0.5 part of defoaming agent and 0.2-0.5 part of preservative. 0.2-0.5 part of a mildew preventive, 0.1-0.2 part of a pH regulator and 2-5 parts of nitrogen. Water seepage, sunlight, acid rain and seawater erosion of a building base material can be effectively prevented, so that corrosion, looseness, stripping and mildew of concrete and an internal steel bar structure are prevented, and the service life of a building is prolonged; in addition, the permeation corrosion of water to the base material is further reduced by utilizing the hydrophobicity of the siloxane modified waterborne polyurethane resin after curing and film forming, and the service life of the building base material can be prolonged for a long time due to the super-strong weather resistance of the siloxane modified waterborne polyurethane resin; a binary package aerosol form is adopted, and the problem that a conventional aerosol product is flammable and explosive is solved.

Description

technical field [0001] The invention relates to the field of waterproof leakage repairing materials, in particular to an aerosol-type siloxane modified waterproof leakage repairing material and a preparation method thereof. Background technique [0002] Under the trend that the world and China require to achieve carbon peak and carbon neutrality, it is necessary to vigorously develop green and environmentally friendly building materials. Under this general environmental trend, environmental protection requirements are becoming increasingly stringent, requiring the coating industry to develop environmentally friendly and low-carbon coating products. The aerosol-type water-based siloxane modified waterproof leak-trap repair material is easy to use, environmentally friendly, easy to carry, and does not require special construction equipment. It can be used for indoor and outdoor corridors, roofs, and sewer pipes in homes, factories, hospitals, schools, and office buildings. Wa...

Problems solved by technology

[0006] In order to solve the technical problems existing in the background technology, the present invention proposes an aerosol-type siloxane-modified waterproof leakage-remedial material and its preparation method. The present invention utilizes the penetrable cementitious surface of the impregnated material with small-molecule silane to penetrate into the concrete The interior reacts chemically with the air exposed in the acidic or alkaline environment and the water molecules in the substrate to form a water-repellent treatment layer, thereby inhibiting the entry of moisture into the substrate, thereby producing waterproof, anti-chlorine ion, and anti-acid and alkali properties , can effectively prevent the base material from corrosion, looseness, peeling, and mildew of the concrete and internal steel structure due to water seepage, sunshine, acid rain, and seawater erosion, and improve the service life of the building; Fog can, using nitrogen as the propellant, put the contents of the water-based silicone modified waterproof leak repair repair material into an independent pouch in the aerosol tank, water-based silicone waterproof leak repair repair material and metal aerosol tank and propellant Form a non-contact isolator, when the valve is pressed, the content of the material liquid is atomized and sprayed through the atomizing nozzle through the extrusion of nitrogen, which solves the problem of poor compatibility between conventional water-based polymer resins and propellants and the corrosion of metal by water-based content Tank problem, the aerosol-type water-based siloxane modified waterproof leak-trap repair material has good storage stability and construction, easy to use and easy to carry, because it uses a water-based system, it does not contain a large amount of organic solvents, such as: Benzene, xylene, acetone, free formaldehyde and other harmful ingredients; after use, it can also avoid the continuous volatilization of harmful substances, causing indoor air pollution and human damage
