Abstract

The invention belongs to the technical field of anti-corrosive coatings, and particularly relates to an anti-corrosive coating for concrete surface and a preparation method thereof. The anti-corrosive coating for concrete surface is divided into a base coating and a surface coating, wherein the base coating is composed of a first component and a second component, the surface coating is composed of a component A and a component B; the first component and the component B both use epoxy resin as a base material; the second component and the component B are respectively composed of a curing agent and a curing promoter. While in use, the first component and the second component are uniformly mixed according to a proportion to obtain the base coating; and the component A and the component B are uniformly mixed according to proportion to obtain the surface coating. Compared with the prior art, the anti-corrosive coating for concrete surface has features of stable performance, strong adhesion, long service life, good corrosion prevention effect, green environmental protection, good decorative effect and simple production process, and can be used in highway bridges, offshore structures, factory buildings or the like. After the anti-corrosive coating is coated once, the high temperature resistance, the acid and alkaline corrosion resistance, and the service life are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of anticorrosion coatings, and in particular relates to an anticorrosion coating for concrete surfaces and a preparation method thereof. technical background [0002] As the main building material of modern life, cement concrete plays a big role in the construction of road traffic and urban buildings. However, it is often corroded by corrosive media during use. If anti-corrosion measures are not implemented, the corrosive media may damage the building structure and even make it lose its use value. This is even more important for traffic and municipal structures, because in traffic structures, building structures are in direct contact with liquid or gaseous media, or are polluted by waste discharged from transport vehicles. In highway traffic, 20%-70% of concrete structures are often eroded by corrosive media due to the influence of wind and sun, automobile exhaust, snow melting agent, oil pollution, etc., a...
