Abstract

The invention provides waterborne rust conversion primer coating with rust and a preparation method thereof. The waterborne rust conversion primer coating with the rust is prepared by uniformly mixinga component A and a component B, wherein the component A is prepared from the following raw material components in parts by weight: 2 to 10 parts of a rust conversion agent, 2 to 5 parts of a rust conversion auxiliary agent, 5 to 8 parts of a stabilizer, 0.5 to 3 parts of a corrosion inhibitor, 2 to 4 parts of a film forming auxiliary agent, 0.1 to 0.3 part of a thickener, 0.3 to 0.6 part of a wetting dispersant, 0.2 to 0.5 part of a de-foaming agent, 0.05 to 0.2 part of fungicide, 30 to 50 parts of waterborne epoxy antirust emulsion and 15 to 25 parts of de-ionized water; the component B isan epoxy curing agent. Therefore, the primer coating has the characteristics of environment friendliness, good adhesive power, acid resistance, alkali resistance, salt spray corrosion resistance and long service life, can be coated with the rust and is convenient to construct.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based rust-carrying-rust-turning-rust primer coating and a preparation method thereof. Background technique [0002] The rust-removing paint is a heavy-duty anti-corrosion paint that can be directly painted on the surface of steel with certain residual rust. become part of the paint film. Rust-reversing paint simplifies the surface treatment procedure before traditional paint coating, greatly reduces the cost of painting and the harm to the environment and construction personnel, and its anti-rust performance is also better than conventional anti-corrosion coatings. Rust-to-rust coatings and their matching intermediate coatings have become the focus and focus of research on heavy-duty anti-corrosion coatings. [0003] In the invention patent of application number CN201310538722.8, a new type of rust-removing coating with rust is introduced, which prepares a synthetic r...
