Problems solved by technology

However, with the continuous development of concrete technology in the direction of high strength and high performance, the strength of concrete structures is getting higher and higher, while the effect of traditional cement-based permeable crystalline waterproof materials is becoming weaker and weaker.
At the same time, because the traditional cement-based permeable crystalline waterproof material needs to be mixed with cement and mortar, it can only be applied to building materials such as plastering mortar and decorative mortar in the application process. No convenient post-processing
At present, many early buildings have not been waterproofed for their building materials during the initial construction. Therefore, once water leakage occurs during subsequent use, it cannot be easily solved by using the existing cement-based permeable crystalline waterproof materials.
Most of the other types of waterproofing agents in the prior art can only be used for covering waterproofing. Once they are separated from the base layer, they will easily leak, and for different types, especially the external or internal construction of irregularly shaped building structures However, the effect of covering waterproofing is often unsatisfactory

Embodiment

[0034] Embodiment, invisible waterproofing agent, its component and the weight percent of each component are: tartaric acid 20%; Sodium fluoride 15%; Silica sol 6%; The solid content of silane emulsion 6%; %.

[0035] Preparation method: Weigh each component according to the above formula ratio, then add tartaric acid, sodium fluoride, silica sol, silane emulsion, and nuciferin to water successively to prepare a mixed solution, and fully stir the mixed solution evenly in the reaction kettle. Then, the impurity in the solution was removed by filtering through an acid-resistant filter with a mesh number of 400, and the clear liquid after filtering was obtained the invisible waterproofing agent prepared in this embodiment.

[0036] How to use: First, pre-treat the base surface to be applied. Oil stains or other sundries on it should be removed, and the surface should be kept dry. The invisible waterproofing agent can be applied to the concrete base surface by brushing.

Abstract

The invention discloses an invisible waterproofing agent and a preparation process thereof and belongs to the field of building materials. The waterproofing agent comprises tartaric acid, sodium fluoride, silica sol, silane emulsion and water. By weight percentage, the tartaric acid accounts for 15-28%, the sodium fluoride accounts for 8-19%, the silica sol accounts for 2-10%, the solid content of the silane emulsion accounts for 1-10%, lotus leaf element accounts for 1-10% and the water accounts for 33-74%. The method comprises the following steps of: weighing the ingredients according to the proportion; adding the tartaric acid, the sodium fluoride, the silica sol, the silane emulsion and the lotus leaf element successively to the water to obtain a mixed solution; stirring fully and evenly the mixed solution in a reaction kettle; and eliminating impurities in the solution by filtering treatment to obtain a clear liquid which is the invisible waterproofing agent. The invisible waterproofing agent provided by the invention can react with hydration products of cement to generate a crystal product which can take the effects of compacting and water proofing and the silane emulsion can further take the effects of water repellenting and water proofing on the surface of the concrete base.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to an invisible waterproofing agent and a preparation process thereof. Background technique [0002] Reinforced concrete is currently the largest building structure material used by humans. The main causes of concrete deterioration processes (physical, chemical, and biological) and steel or prestressed reinforcement deterioration are freeze-thaw cycles, alkali-aggregate reaction, sulfate attack, shrinkage cracking, and steel corrosion. [0003] For any of the above-mentioned deterioration processes, the cause of expansion and cracking is related to water, and water is also the carrier for the migration of aggressive media (such as chloride salts, sulfates, etc.) into the concrete. Water is not only the transmission medium of destructive substances, but also the necessary condition for the occurrence of damage and the basis for the establishment of many failure mechanis...
