Waterproof and corrosion-resistant coating for coastal region

Abstract

A waterproof and corrosion-resistant coating for a coastal region is characterized by being prepared from a component A and a component B, wherein the component A is prepared from the following raw materials in parts by weight: 20-40 parts of epoxy resin, 0.1-1 part of graphene, 30-50 parts of powder, 1-5 parts of an auxiliary, and 10-30 parts of deionized water; the component B is prepared from the following raw materials in parts by weight: 5-10 parts of an amine curing agent, 1-2 parts of an auxiliary and 5-10 parts of deionized water. The waterproof and corrosion-resistant coating for the coastal region has the advantages of good water resistance, high chloride penetration resistance, good alkali resisting and salt corrosion resisting properties and the like, and is environmentally friendly and odorless, meanwhile, the preparation method is simple, and the waterproof and corrosion-resistant coating can be scraped and can also be sprayed during construction.

Description

technical field [0001] The invention relates to a waterproof and anticorrosion coating, in particular to a waterproof and anticorrosion coating used in coastal areas. Background technique [0002] Building waterproofing engineering is a systematic project, and building waterproofing system is an important part of the whole construction project, not only to ensure the waterproofing of the building, but also to ensure its function. In coastal areas, the waterproofing of buildings or structures has always been a major problem plaguing the waterproofing industry. The soil and groundwater in coastal areas contain high-concentration corrosive saline-alkali media, among which chloride ions are the main cause of corrosion of steel bars in concrete structures. Once the waterproof layer fails or a large amount of chloride ions penetrate into the interior of buildings or structures, it must be It will lead to a reduction in the strength of the main structure of the building, resulting...

Problems solved by technology

However, there is no research report on using graphene in waterproof coatings to improve its anticorrosion performance in the prior art.

Therefore, it is urgent to explore a graphene-based waterproof and anti-corrosion coating for coastal areas to overcome the deficiencies of existing waterproof coatings in terms of salt, alkali corrosion resistance and chloride ion penetration resistance.
