Qercetin waterproof agent

Abstract

The invention discloses a qercetin waterproof agent and relates to the technical field of building materials. The invention adopts a technical scheme that: the qercetin waterproof agent is prepared from 100 parts of deionized water, 3 part of lotus leaf extract, 8 parts of absolute ethanol, 8 parts of methyl silicic acid and 5 parts of potassium hydroxide. The manufacturing process of the qercetin waterproof agent comprises: uniformly mixing the absolute ethanol and the methyl silicic acid, reacting for 30 minutes in a natural environment, adding the deionized water in a reaction kettle and heating to 50 to 60 DEG C; adding lotus leaf extract and potassium hydroxide, continuously heating to 100 DEG C, adding the reacted methyl silicic acid into a reaction kettle, and reacting at a constant temperature for 50 minutes; pouring the reaction solution into a settling tank for cooling and settling; and pouring clear liquid obtained by settling into a filling machine for filtering, and filling to obtain finished products. The waterproof agent produced by the invention is an environmentally-friendly product and is free from formaldehyde, toxin, pungent odor, flammability, volatilization and steel bar corrosion. The waterproof performance is reliable, the water proof life is long, and the acid resistance, alkali resistance and weather resistance are high. The construction is safe, the operation is simple and convenient, and the price is reasonable.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a high-performance waterproof material. Background technique [0002] At present, the cracking and leakage of buildings and various structures has almost become a major quality problem in today's concrete structures. There is a saying that "the sky is cloudy and it rains all night", which expresses people's helplessness about house leakage. Cement concrete usually has a large amount of water, and after hardening and drying, a large number of connected capillary pores are formed inside the cement stone and at the interface of the aggregate and the slurry. In addition, the volume shrinks during the drying process, and it is prone to cracking after being restrained, which is even more aggravated. its leakage hazard. For a long time, people have adopted various measures to solve the anti-leakage problem of concrete, such as increasing the amount of cement, improving aggre...

AI Technical Summary

Problems solved by technology

For a long time, people have adopted various measures to solve the anti-leakage problem of concrete, such as increasing the amount of cement, improving aggregate gradation, etc., but the effect is limited, and the cost increases, and the crack problem still cannot be solved

In the past few decades, people have also adopted measures to improve the impermeability of concrete by adding admixtures such as triethanolamine and ferric chloride, but none of them can solve the cracking problem of concrete, and improper use of triethanolamine can easily cause serious damage to concrete performance. The chemical iron has a corrosive effect on the internal steel bars and has been restricted in use
