Embodiment 1

[0021] 1) Preparation of material A-emulsion part;

[0022] ① Emulsify the functional monomers styrene, acrylic acid, butyl acrylate, methyl methacrylate with water and OP-10, and add PH regulator and protective agent into the reaction kettle.

[0023] ② Add quantitative initiator potassium persulfate to the main reaction kettle where part of the emulsion is put into, and raise the temperature to 70-80°C;

[0024] ③Under stirring, carry out polymerization, then gradually add the remaining emulsion and initiator to initiate, add cross-linking agent N-methylolacrylamide during the initiation process, and continue to react for 3 hours to finish dripping.

[0025] ④ Under stirring, add redox agents ammonium persulfate and sodium bisulfite for post-treatment. Raise the temperature by 5-10 degrees, and then react for 1.5 hours.

[0026] ⑤ Cool down below 50 and filter.

[0027] ⑥Place it in a storage tank for later use.

[0028] 2) Preparation of B material-powder dispersion par...

Abstract

The invention discloses an environment-friendly aqueous paint with excellent anticorrosive property. A method for preparing the environment-friendly aqueous paint is characterized by comprising the following steps of: through modifying a polymer emulsion, crosslinking in different degrees and improving the physical and chemical properties of the paint by adopting a nuclear-shell polymerization method, introducing powders with special properties during paint preparation, and carrying out curing and film forming to obtain the single-component aqueous anticorrosive paint with excellent properties such as high strength and tenacity of a coating, high chemical resistance, high impact resistance strength, and the like. The environment-friendly aqueous paint with excellent anticorrosive property has the characteristics of excellent acid resistance, alkali resistance, high temperature resistance, impact resistance, low VOC (Volatile Organic Compound), and the like, does not combust or explode, does not belong to a dangerous article, solves unnecessary troubles in the transportation process of the traditional paint, and solves the problems of the traditional solvent based paint, i.e., the toxic and harmful operations exist in the using process and the atmosphere pollution is caused by continuously volatilized harmful matters, such as toluene, dimethylbenzene, and the like in the using process within several years.

Description

technical field [0001] The invention relates to a new water-based environment-friendly anticorrosion coating and a method for preparing the emulsion thereof, belonging to an environment-friendly new material. Background technique [0002] The anti-corrosion market in my country is mostly oil-based anti-corrosion, which pollutes the environment during construction, causing great pollution to the construction personnel and the surrounding environment. Many anti-corrosion constructions are required to strictly control environmental pollution, and at the same time have stricter requirements on anti-corrosion performance. Water-based anti-corrosion coating products are mainly made of modified acrylates, and are processed by adding special anti-oxidation and anti-corrosion powder and additives. Compared with traditional oil-based paints, there is no irritating smell after construction, it is friendly to the environment, and has no toxic and side effects on construction personnel. ...
