Problems solved by technology

[0004] At present, most of the rusty paints used in China are solvent-based paints. Ordinary solvent-based rusty paints contain a large amount of organic solvents, which are toxic, harmful, not environmentally friendly, pollute the environment, endanger human health, and have the risk of fire; The metal antirust paint prepared by acrylic emulsion or tertiary acrylic emulsion cannot be painted with rust, and a large amount of manual rust removal is required, and the anti-rust and anti-rust capabilities are very poor. One of the important varieties that need to be developed urgently

Abstract

The invention relates to the field of materials and discloses an auto-rust converting rust-containing corrosion resistant emulsion and preparation method thereof. The auto-rust converting rust-covering corrosion resistant emulsion is prepared as follows: a mixture of at least one from metacrylic acid ester or acrylic ester and styrene is selected as an allyl monomer; methacrylic acid phosphate, methacrylic acid glycidyl ester and vinyl tri-methoxysilane are selected as functional monomers; a mixture diester of at least one from acrylic acid, or methacrylic acid and acrylamide is selected as afunctional monomer; poly (ethylene glycol) phosphate, allyl alkylphenol polyoxyethylene ammonium sulfate, and the like, are selected as emulsifying agents. The emulsion prepared has the auto-rust converting function, does not a huge amount of manual work to eliminate rusts during coating and can be coated by containing rust. Moreover, the emulsion has good corrosion resistant capacity, is safe and environmental friendly, is innocuous, can not cause fire, and reduces the working intensity and harmfulness of constructors.

Description

technical field [0001] The invention belongs to the field of materials, and relates to a self-rotating rust-with-rust anti-rust emulsion, which is an acrylate copolymer emulsion. Background technique [0002] Rust paint is a kind of primer for protecting metal, which can be directly painted on the metal surface with residual rust, passivate with rust, and play a role of stabilization or transformation. When using it, it is only necessary to remove floating rust on the rusty surface, which can improve working conditions, reduce the workload of rust removal, and increase production efficiency. [0003] Rust-transfer anti-rust coatings can be directly applied to metal surfaces without pretreatment, and have anti-corrosion effects; complex pre-painting processes such as grinding, pickling, and water washing are exempted, which can reduce costs and improve work efficiency. At the same time, it can convert the rust layer on the metal surface into a hydrophobic passivation layer, ...
