Problems solved by technology

[0006] Inorganic curing agents are stable in performance, non-toxic and tasteless, and cheap in price, but their film-forming properties are poor, and they cannot effectively prevent the phenomenon of efflorescence in concrete pores, which will affect the appearance of concrete after spraying; organic curing agents are usually emulsion-type and solvent-type, Emulsion-based curing agents have a firm curing film after curing, which is difficult to break, affecting subsequent processes, and the price is also high. Solvent-based curing agents contain volatile solvents that are easy to pollute the environment and have a strong smell

Synthetic example 1

[0029] Synthetic Example 1 Synthesis of Bromine-Containing Compounds

[0030] Add 80g of potassium bromide and 0.4g of sodium silanolate to 100g of diethylene glycol, stir and react in an ice-water bath for 3 hours, raise the temperature to room temperature, and stir for 2 hours to react; wash the reaction product twice with water, separate the organic layer, anhydrous magnesium sulfate Drying, filtering, and distilling out the product under reduced pressure are bromine-containing compounds; the reaction formula is as follows:

[0031]

Synthetic example 2

[0032] Preparation of Synthetic Example 2 Moisturizing and Antifungal Agent

[0033] The main reactions are as follows:

[0034]

[0035] First, mix 1Kg of bromine-containing compound, 10g of lanthanum trifluoromethanesulfonate and 200g of imidazole, place in a container, and react with microwave heating to obtain a crude product; add 1.8Kg of water and 120g of ethylenediamine-N to the above crude product, N′-diacetic acid and 360g of ammonia water with a concentration of 30% were soaked for 10 hours, filtered, and the filter residue was dried to obtain a solid powder; the microwave heating time was 150 seconds, and the power was 720w;

[0036] Then 1Kg of solid powder, 20Kg of 1,3-butanediol, and 120g of potassium carbonate were added to the reactor, refluxed for 0.5 hours, and cooled to room temperature to become the moisturizing antifungal agent;

Synthetic example 3

[0037] Preparation of Synthetic Example 3 Curing Agent

[0038] (1) Mix 100g butyl acrylate and 40g deionized water to obtain mixture A;

[0039] (2) In a nitrogen atmosphere, add 120g of deionized water, 6.4g of nonylphenol polyoxyethylene ether and 1.6g of NaHCO to the reactor in sequence 3 , stirring at 50°C for 30 minutes to obtain mixture B;

[0040] (3) Mixture A and mixture B were mixed and stirred for 55 minutes to obtain mixture C;

[0041] (4) Add 64g of tetraethoxysilane into the mixture C; then keep the temperature at 60°C for 0.5h; stop heating and cool to room temperature; then add 72g of sodium silicate to obtain the curing agent.

Abstract

The invention discloses a maintenance method for a concrete member. The maintenance method for the concrete member specifically comprises the steps that in a ventilation environment, after pouring of the concrete member is completed, the surface of the concrete member is coated with a layer of homemade curing agents which have the function of preventing water loss inside concrete; after the curing agents become drier, a layer of homemade moisture preserving mould inhibitor is sprayed to achieve the functions of absorbing air moisture and ensuring the humidity of the surface of the concrete member; last, maintenance of the concrete member is completed as long as another layer of the homemade curing agents is smeared. The maintenance method for the concrete member is good in maintenance effect, environmentally friendly, and low in cost, and the concrete maintained through the maintenance method has the advantages of being high in strength, excellent in durableness, and excellent in anti-mold property, thereby being capable of being applied to the field of modular construction.

Description

technical field [0001] The invention belongs to the technical field of buildings, and in particular relates to a maintenance method for concrete components. Background technique [0002] Modular building is a kind of assembly technology. It uses prefabricated concrete module components, such as walls, to assemble various houses, which are easy to construct and flexible to assemble. The modular components are prefabricated in the factory, which facilitates the organization of industrialized production, improves work efficiency, reduces material consumption, and is less affected by seasons. Modular buildings have the characteristics of fast construction speed, good seismic performance, large usable area, light building weight, simple construction, flexible assembly, low labor and material consumption, and modular components can be designed, so they have good application value in urban construction. [0003] In addition to the load-bearing wall and beam structure, a complete h...
