Embodiment 1

[0033] A concrete repair agent, mainly including acrylic resin, emulsifier, penetrant and diluent, wherein the emulsifier can use alkylphenol polyoxyethylene ether, dibenzyl biphenyl polyoxyethylene ether or styrylphenol formaldehyde resin One of the polyoxyethylene ethers can also be used in combination. The penetrating agent adopts fatty alcohol polyoxyethylene ether, the diluent adopts water and organic solvent, and the organic solvent adopts butyl acetate; in this embodiment, the emulsifier Alkylphenol polyoxyethylene ether is used.

[0034] Take a clean container, dissolve 20 parts of acrylic resin in 10 parts of butyl acetate, add 10 parts of water and 1 part of emulsifier after it is completely dissolved, stir at high speed to form an emulsified suspension; then pour 3 parts of penetrant into Until it is stirred evenly, the preparation of the concrete repair agent is completed.

Embodiment 2

[0036] A concrete repair agent, mainly including acrylic resin, emulsifier, penetrant and diluent, wherein the emulsifier can use alkylphenol polyoxyethylene ether, dibenzyl biphenyl polyoxyethylene ether or styrylphenol formaldehyde resin One of the polyoxyethylene ethers can also be used in combination. The penetrating agent adopts fatty alcohol polyoxyethylene ether, the diluent adopts water and organic solvent, and the organic solvent adopts butyl acetate; in this embodiment, the emulsifier Styrylphenol formaldehyde resin polyoxyethylene ether is used.

[0037] Take a clean container, dissolve 60 parts of acrylic resin in 30 parts of butyl acetate, add 30 parts of water and 30 parts of emulsifier after it is completely dissolved, and stir at high speed to form an emulsified suspension; then pour 10 parts of penetrant into Until it is stirred evenly, the preparation of the concrete repair agent is completed.

Embodiment 3

[0039] A concrete repair agent, mainly including acrylic resin, emulsifier, penetrant and diluent, wherein the emulsifier can use alkylphenol polyoxyethylene ether, dibenzyl biphenyl polyoxyethylene ether or styrylphenol formaldehyde resin One of the polyoxyethylene ethers can also be used in combination. The penetrating agent adopts fatty alcohol polyoxyethylene ether, the diluent adopts water and organic solvent, and the organic solvent adopts butyl acetate; in this embodiment, the emulsifier Dibenzyl biphenyl polyoxyethylene ether is used.

[0040] Take a clean container, dissolve 40 parts of acrylic resin in 20 parts of butyl acetate, add 20 parts of water and 16 parts of emulsifier to it after complete dissolution, stir at high speed to form an emulsified suspension; then pour 6 parts of penetrant into Until it is stirred evenly, the preparation of the concrete repair agent is completed.

Abstract

The invention relates to a concrete repair agent. The concrete repair agent is prepared from, by weight, acrylic-based resin, an emulsifying agent, a penetrating agent and a diluting agent. The concrete repair agent is commonly known as a concrete solder and is a waterborne environment-friendly agent, and the concrete repair agent is capable of having cross-linking reaction with dust generated ina cement and concrete grinding process to enable re-setting and hardening, and defects of holes, cracks and the like of concrete repaired. By application of the concrete repair agent to new and old concrete combination faces, adhesion firmness of the new and old concrete combination faces can be remarkably improved, and concrete bulging, layering and shedding can be prevented. In addition, the concrete repair agent is simple in operation, early strength of concrete can be quickly improved, an integral construction period is shortened, and concrete compactness is improved to make it easy for grinding and polishing.

Description

technical field [0001] The invention relates to a building material, in particular to a concrete repair agent and its application. Background technique [0002] It has been more than 180 years since the advent of concrete in 1830, and many important and large-scale infrastructures have been constructed of concrete; however, over time, some of these infrastructures are due to harsh natural environmental conditions, such as: The large temperature difference between day and night, the seasonal dryness and wetness, sea wave erosion, severe saline-alkali corrosion, etc., as well as the frequent occurrence of traffic accidents in some areas, have caused serious damage to cement and concrete infrastructure, especially highways. [0003] However, considering that the amount of concrete used in existing buildings is large, and most of the concrete cannot be recycled after damage, the maintenance of concrete works is very important, especially for large-volume concrete such as dams an...
