Problems solved by technology

In terms of maintenance, the concrete structure that has already been carbonized is often pulverized or even peeled off, so it is impossible to effectively attach new concrete to it.
Especially on cloudy or rainy days, because the environment is too humid, ordinary concrete cannot effectively adhere to it.

preparation example Construction

[0057] A method for preparing an anti-carbonization coating with super adaptability, comprising the following steps:

[0058] S01. Preparation of penetrating primer: mix the special penetrating emulsion, deionized water, film-forming aid, defoamer, and emery in the raw materials corresponding to the proportion of penetrating primer at a speed of 600-800 rpm, and slowly add the corresponding penetrating primer after 1 hour. The lithium silicate aqueous solution in the raw material components is mixed evenly, and after stirring for 1 hour, the measured pH value is 9-10;

[0059]S02. Preparation of intermediate paint: mix the water-based hyperbranched emulsion, deionized water, special additives, antifungal agent, and tungsten-doped nano-vanadium dioxide dispersion liquid in the raw materials corresponding to the proportion of component A at a speed of 600-800rpm. Stir for 1 hour, and measure the PH value to be 7-8; mix the special cement, quartz sand, talcum powder, and powdery ...

specific Embodiment 1

[0062] This embodiment provides a preparation process of an anti-carbonization paint penetrating primer, intermediate paint and top coat with super adaptability. Use 300kg of deionized water, 200kg of special penetrating emulsion, 3kg of cetyl alcohol ester, 0.2kg of defoamer, and 50kg of diamond for the penetrating primer. Mix evenly at a speed of 600-800rpm, and slowly add 500kg of silicon Lithium acid aqueous solution was mixed evenly, and after stirring for 1 hour, the measured pH value was 9-10. The middle layer paint is two-component, and component A uses 497kg of water-based hyperbranched emulsion, 500kg of deionized water, 2kg of special additives, 1kg of antifungal agent, and 2kg of tungsten-doped nano vanadium dioxide dispersion liquid, at a speed of 600-800rpm Mix evenly, stir at a constant speed for 1 hour, and measure the PH value to be 7-8. Component B is 400kg of special cement, 594kg of quartz sand, 5kg of talcum powder, and 1kg of powdered defoamer. Mix evenly...

specific Embodiment 2

[0064] The difference between this embodiment and Example 1 is only the proportioning difference of the formula, specifically as follows, the penetrating primer penetrating primer uses 150 kg of deionized water, 100 kg of special penetrating emulsion, 1.5 kg of cetyl alcohol ester, and 0.1 kg of defoaming Agent, 30kg diamond jade, 300kg lithium silicate aqueous solution.

[0065] The middle layer paint is two-component, A component uses 150kg of water-based hyperbranched emulsion, 600kg of deionized water, 1kg of special additives, 0.5kg of antifungal agent, 1kg of tungsten-doped nano-vanadium dioxide dispersion, and B component is 200kg Special cement, 600kg quartz sand, 1kg talcum powder, 1kg powdered defoamer.

[0066] For the topcoat, 250kg of titanium dioxide, 100kg of nano ceramic dispersion, 150kg of deionized water, 320kg of water-based hyperbranched modified silicon acrylic emulsion, 1kg of defoamer, 20kg of cetyl alcohol ester, 3kg of antifungal agent, 5kg special a...

Abstract

The invention discloses an anti-carbonization coating with super-strong adaptability and a preparation method thereof, and relates to the technical field of concrete. The coating comprises a permeableprimer, a middle-layer paint and a finish paint, and the permeable primer comprises a lithium silicate aqueous solution, a special permeable emulsion, deionized water, a coalescing agent, a defoamingagent and diamond jade in percentage by weight; the middle-layer paint comprises a group A and a group B, wherein the group A comprises a water-based hyperbranched emulsion, a special auxiliary agent, a mildew preventive and a tungsten-doped nano vanadium dioxide dispersion liquid; and the group B comprises special cement, quartz sand, talcum powder and a powdery defoaming agent; and the finish paint comprises a water-based hyperbranched modified silicone acrylic emulsion, a mildew preventive, a coalescing agent, deionized water, a defoaming agent, a wetting agent and a thickening agent. Thecoating can effectively prevent water from reacting with repaired concrete, can generate good adherence with middle-layer paint, can quickly extrude water to the surface, is not influenced by environmental humidity, has good ageing resistance, further protects the concrete and reduces the carbonization opportunity.

Description

technical field [0001] The invention belongs to the technical field of concrete, and in particular relates to an anti-carbonization coating with super adaptability and a preparation method of the anti-carbonization coating with super adaptability. Background technique [0002] Due to the rapid development of the city, many infrastructures, houses, ports, etc. are supported by a large number of concrete structures. Concrete structures are often damaged before reaching the default service life, and the durability and aging resistance of concrete materials have been widely concerned. The carbonization of concrete is the main reason for reducing the service life. [0003] When CO2 reacts with calcium hydroxide in concrete to produce calcium carbonate, which reduces the pH value of the concrete solution to 8.5-9.0, it means that the concrete has been carbonized, causing the internal steel bars to rust and cracks in the concrete structure. In terms of maintenance, the concrete s...
