Abstract

The invention relates to a rusty protective coating with a rust conversion function and a preparation method. The rusty protective coating comprises 10-40 parts of a rust conversion agent, 60-90 partsof an acidic resin emulsion, an antifoaming agent accounting for 0.1-0.5% of the total mass of the acidic resin emulsion and the rust conversion agent, a thickening agent accounting for 0.1-0.5% of the total mass of the acidic resin emulsion and the rust conversion agent, and a wetting agent accounting for 0.1-0.5% of the total mass of the acidic resin emulsion and the rust conversion agent. Therusted protective coating with the rust conversion function is uniformly brushed on the surface of a rusted reinforcing steel bar, a rust layer can be converted and dissolved to generate a polymer protective film under the condition of normal temperature, the utilization rate of the reinforcing steel bar is increased by effectively converting the rust layer, the bonding and anchoring performance of the coating and concrete is excellent when a reinforced concrete structure is poured again, and an anti-rust action is achieved without affecting the performance of the concrete. The rusty protective coating has the characteristics of environmental protection, low cost, strong adhesive force, high corrosion resistance and the like.

Description

technical field

[0001] The invention relates to a protective coating material with rust, in particular to a long-acting polymer protective coating with rust conversion function. The invention also relates to a method for preparing the protective coating. Background technique

[0002] In the general atmospheric environment, the reduction of concrete alkalinity caused by carbonization is the main reason for the corrosion of steel bars in concrete. Concrete, when the surface of the steel bar reaches a certain concentration, even if the alkalinity of the concrete does not decrease, the steel bar will rust. Due to the uncertainty in the transportation and construction process, corrosion products have been produced on the surface of the steel bar before pouring, which significantly reduces the mechanical properties of the steel bar, resulting in a decrease in the safety and durability of the building structure. The time used also affects the project investment benefit and the ra...
