Anti-corrosive efficient waterproof agent

Abstract

A disclosed anti-corrosive efficient waterproof agent is prepared from the following raw materials in parts by weight: 33-53 parts of deionized water, 2-7 parts of nanometer silicon dioxide, 2-6 parts of sodium alkyl sulfate, 3-6 parts of sodium polyacrylate, 2-5 parts of ethyl silicate, 4-8 parts of chrome oxide, 3-6 parts of an ethanolamine, 10-20 parts of sulfur trioxide, 5-10 parts of n-butyl benzoate, 15-25 parts of tetraethyl orthosilicate, 2-6 parts of a benzoate and 6-14 parts of phenyl salicylate. The provided anti-corrosive efficient waterproof agent is good in weatherability, high in caking ability and substantial in waterproof and anticorrosion effects, is especially applicable to ocean engineering, and does not contain substances harmful to human body.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an anti-corrosion and high-efficiency waterproofing agent. Background technique [0002] With the rapid development of urban and rural construction in our country, people have higher requirements on the living environment and quality. Building waterproofing is an important part of construction engineering. It occupies a very important position in construction engineering. The waterproof technology of buildings is a special measure to ensure that buildings are not eroded by water and the internal space is not harmed.

Most of these products are products based on nitrate and nitrite. Aggregate reaction is highly valued, and the nitrate and nitrite admixtures specified in GB 50119 cannot be used in re...

AI Technical Summary

Problems solved by technology

[0003] At present, there is no similar product in the known technology at home and abroad, and there are only independent concrete rust inhibitor products on the market. Most of these products are products based on nitrate and nitrite. High attention is paid to the reaction of aggregates, and the admixtures of nitrate and nitrite specified in GB 50119 cannot be used in residential and other projects, and the application of this kind of rust inhibitor products is limited

There are also some alkali-free concrete rust inhibitor products, these products are mainly imported products, but the price is very expensive, resulting in an increase in the cost of concrete

Moreover, when some rust inhibitor components are added to concrete alone, it is easy to have poor compatibility with other admixtures in concrete, which is not conducive to ensuring the quality of concrete.

Although the concrete waterproofing agent products on the market meet the requirements of the JC 474 standard, they do not reflect the anti-corrosion and anti-embroidery performance
