Problems solved by technology

[0006] In the prior art, an aqueous emulsion composition comprising an alkylalkoxysilane, a surfactant (emulsifier), and water is used, and the aqueous emulsion composition will remain on the surface of the coated substrate due to the surfactant, Therefore, the surface of the substrate cannot be sufficiently hydrophobized
The resulting product has poor resistance to chloride ion penetration

Abstract

The invention relates to a composition used as a concrete maintenance assistant. The composition comprises, by weight, 100 parts of trihexadecenoin, 0.01-0.05 parts of 1-butylsulfonic acid-3-methylimidazolium tetrafluoroborate, 0.01-0.05 parts of N-butyl-N-methylpiperidine bis(trifluoromethanesulfonyl)imide salt, 1-5 parts of disodium laureth (1~4) sulfosuccinate and 1000 parts of tetrahydrofuran.

Description

technical field [0001] The invention relates to a concrete additive, in particular to a composition used as a concrete maintenance additive. Background technique [0002] Concrete maintenance additives are based on composite polar substances such as silicates, and are added with catalysts and polymers. After mixing and reacting, water resistance, impermeability, crystallinity, protection, corrosion resistance, and anti-aging properties are formed. A six-in-one rigid crystalline waterproof material. It is non-toxic, tasteless, non-combustible, and is an environmentally friendly waterproof material. And has better permeability than water. After spraying on the surface of concrete, it can quickly penetrate into the interior of the concrete, promote the release of calcium ions and undergo a secondary chemical reaction with free alkali and other chemical substances to form completely hydrophobic calcium silicate ion gel crystals. Fill gaps and capillary holes to make concrete ...
