Description

Technical Field

[0001] The present invention relates to the field of material technology, and more specifically, to a blended surface self-repairing reinforcement material and a preparation method and an application method thereof. Background Art

[0002] Permeable crystalline material is a liquid substance used for building structural reinforcement and waterproofing. The principle of reinforcement and waterproofing of permeable crystalline material is that when the material encounters water, the active substances and catalysts in the material dissolve in water and penetrate into the concrete structure with water as a carrier. In the process of penetration and movement, the active substances in the material react chemically with anion groups such as calcium ions, silicate ions, sulfate ions, etc. in the pores inside the structure, and generate a certain amount of water-insoluble crystalline substances in the pores. These crystalline substances and hydration products are generated in the pores and gaps along the way, so that the gaps in these structures are filled and blocked, thereby blocking these channels that originally belonged to water seepage and migration, effectively reducing the amount of water seepage in the structure, improving the waterproof ability of the structure, and reinforcing the original structure at the same time.

[0003] Traditional cement-based permeable crystallization materials have good cementitiousness, high stone strength, convenient slurry preparation, economy and environmental protection, but the slurry has poor stability, easy precipitation and water separation, and insufficient waterproof and anti-seepage capabilities. Compared with cement slurry, cement-water glass permeable crystallization liquid has improved anti-seepage ability, shortened solidification time and improved fluidity, but it is a two-component material with complex construction operations. At the same time, the solidified slurry has insufficient strength and toughness, low durability and is prone to brittle failure. Although chemical permeable crystallization materials have excellent waterproof and anti-seepage properties, they have high material costs, complex preparation processes, and may cause harm to the environment.

[0004] In summary, there is currently a lack of an economically feasible solution that has good concrete repair and reinforcement effects, long service life, and waterproof and anti-seepage effects. Summary of the invention

[0005] In view of the above problems, the purpose of the present invention is to provide a blended surface self-repairing reinforcement material and a preparation method and an application method thereof. The prepared blended surface self-repairing reinforcement material has excellent adhesion and anti-permeability, good repair and reinforcement effect, long service life, simple preparation, strong economy, and can better solve the problems existing in the prior art.

[0008] In addition, a preferred solution is that the complex catalyst is any one of sodium acetate, sodium nitrate, sodium sulfate, and magnesium fluoride silicate, or at least two of them mixed in any proportion.

[0009] In addition, a preferred solution is that the water retention enhancer is any one of hydroxypropyl methylcellulose, sodium carboxymethyl cellulose, ethylenediaminetetraacetic acid, sodium polyacrylate, or at least two of them mixed in any proportion.

[0014] The mixed liquid is heated and stirred to make the mixed liquid uniformly mixed, and the temperature is 30-40° C. to obtain a blended surface self-repairing reinforcement material.

[0015] In addition, a preferred solution is that during the heating and stirring of the mixed liquid to make the mixed liquid evenly mixed and the temperature of the mixed liquid is 30-40°C to obtain the blended surface self-repair reinforcement material, the mixed liquid is heated and stirred in a constant temperature water bath with a stirring function.

[0016] In addition, a preferred solution is that when the mixed liquid is heated and stirred in a constant temperature water bath with a stirring function, the rotation speed is set to 200-1000 r / min, and the uniform stirring time is at least 30 min.

[0017] The present invention also provides an application method of the above-mentioned blended surface self-repairing reinforcement material, comprising the following steps:

[0018] Cleaning the surface of the concrete test block, determining the location of the cracks on the surface of the concrete test block and measuring the size of the cracks;

[0019] Determine the amount of the blended surface self-repairing reinforcement material according to the crack position and crack size of the concrete test block, and apply the blended surface self-repairing reinforcement material to the cracks on the surface of the concrete test block based on the amount;

[0027] Figure 2 The present invention is a flow chart of an application method of a blended surface self-repairing reinforcement material according to an embodiment of the present invention. DETAILED DESCRIPTION

[0028] In the following description, for the purpose of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more embodiments. However, it is apparent that these embodiments may also be implemented without these specific details.

[0029] In view of the problems existing in the prior art mentioned above, it is necessary to provide a material with good adhesion and anti-permeability, good effect on repairing and reinforcing concrete cracks, long service life, simple preparation and strong economy. The present invention proposes a blended surface self-repairing reinforcement material and its preparation method and application method.

[0030] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] In order to illustrate the blended surface self-repairing reinforcement material provided by the present invention and its preparation method and application method, Figure 1 The preparation process of the blended surface self-repairing reinforcement material according to an embodiment of the present invention is shown; Figure 2 The application process of the blended surface self-repairing reinforcement material according to an embodiment of the present invention is shown.

[0034] The self-repairing reinforcement material penetrates into the interior of the concrete. The chemically active substances use water as a carrier and penetrate into the interior of the matrix to promote further hydration of the unhydrated particles in the concrete or undergo a complexation-precipitation reaction with some hydration products to generate water-insoluble products, thereby achieving the repair of cracks.

[0035] Among them, by compounding the complex catalyst, that is, containing the early strength accelerating component, the setting time after construction can be effectively shortened, the hardening process can be accelerated, and the hardening can be made to maintain high strength and excellent bonding performance while hardening quickly, and the early concrete strength level can be improved, thereby significantly reducing the construction and maintenance cycle. Compared with traditional materials, the solidification and hardening speed is faster, and at the same time it has stronger anti-permeability performance. By compounding water-soluble organic silicon materials, silicon ions react chemically with inorganic potassium salts to form insoluble irreversible inorganic substances to fill pores and cracks, thereby improving the strength, waterproof performance, durability and self-healing properties of concrete. By using inorganic silicon materials, water-soluble organic silicon materials, water-retention enhancers and complex catalysts as the main raw materials, each raw material has good compatibility with concrete, low cost, and easy construction. The above main raw materials are compounded and used, and the synergistic effect between each other makes the prepared self-repairing reinforcement material not only have good bonding and anti-permeability effects, but also can improve the overall strength, mechanical properties, durability and crack resistance of concrete, thereby playing a good self-repairing reinforcement role on concrete cracks.

[0045] As a preferred embodiment of the present invention, the mixed liquid is heated and stirred to make the mixed liquid uniformly mixed, and the temperature is 30-40° C. to obtain the blended surface self-repairing reinforcement material.

[0046] The mixed solution is heated and stirred in a constant temperature water bath with a stirring function.

[0048] Specifically, heating and stirring the mixed liquid in a constant temperature water bath with a stirring function can further simplify the preparation process and make the uniformity of heating and stirring of the mixed liquid easier to control, thereby making the prepared self-healing reinforcement material more effective.

It effectively shortens the setting time after construction and accelerates the hardening process by compounding complex catalyst (containing early strength accelerating coagulation component), so that it can harden rapidly while maintaining high strength and excellent bonding performance, and improves the early concrete strength level, thereby significantly reducing the construction and maintenance cycle. Compared with traditional materials, the solidification and hardening speed of the present invention is faster, and it also has stronger impermeability.
