Concrete surface modifier, and preparation method and use method thereof

Abstract

The invention discloses a concrete surface modifier, and a preparation method and a use method thereof. The concrete surface modifier is prepared from the following raw materials in parts by weight: 40-60 parts of citric acid, 15-20 parts of acetic acid, 10-15 parts of ethylenediamine tetraacetic acid, 5-10 parts of polyether carboxylate, 3-5 parts of high-carbon fatty ester sulphonate, 2-6 parts of alkylolamide phosphate, 1-5 parts of diethylenetriaminepenta acid, 2-5 parts of nipagin ester, 10-15 parts of sodium gluconate, 8-12 parts of guar gum powder, 5-10 parts of polyacrylamide, 3-6 parts of cyclohexanone peroxide, and 6-12 parts of sucrose. According to the concrete surface modifier, organic acid with relatively low acidity is adopted as the raw materials, so that the concrete surface modifier is milder in a using process; compounded organic acid cooperates mutually, so that the effect of compounded organic acid is superior to the effect of single organic acid; and by use of the concrete surface modifier, cracks are prevented from being formed on the concrete surface, and fine cracks can be repaired.

Description

technical field [0001] The invention belongs to the field of concrete, in particular to a concrete surface corrector and its preparation method and application method. Background technique [0002] At present, the existing concrete surface modifiers and their preparation methods and use methods mostly use inorganic acids or inorganic acid salts as raw materials. For example, CN201410525586.3 discloses the use of oxalic acid, dilute sulfuric acid or dilute hydrochloric acid. The reaction in the process is relatively strong, and the acid is easy to corrode the substrate during use, and it will also damage the human body. Contents of the invention [0003] The invention provides a concrete surface modifier and its preparation method and application method, which are used to solve the defects in the prior art. [0004] The present invention is achieved through the following technical solutions: [0005] The concrete surface modifier and its preparation method and use method ...
