Problems solved by technology

[0003] However, due to the limitations of current water-based resin technology, water-based industrial coatings are only used in general industrial fields. For heavy-duty anti-corrosion fields, especially C4 and above environments, such as marine engineering, marine, heavy chemical and other fields, water-based industrial coatings are currently difficult to apply. Meet the requirements of anti-corrosion of steel structure

Embodiment 1

[0031] First prepare the water-based resin containing the hyperbranched structure, and prepare the raw materials according to the following components and the total fraction:

[0032]

[0033] The deionized water was added into a storage tank with stirring, pre-mixed for 30 minutes in a stirring state, and injected into a pipeline reactor with a temperature regulating device at a rate of 3 liters per minute by a delivery pump with a flow meter.

[0034] An initiator dripping device is installed at the monomer inlet of the pipeline reactor, and the initiator uses a 10% aqueous solution of ammonium persulfate.

[0035] While the monomer is being injected, the initiator is injected at a rate of 0.2 liters per minute in the first hour, and the reaction polymerization temperature is controlled at about 90°C. After the body is all injected from the mixing tank, the cooling water on the outer wall of the pipe reactor is passed into it.

[0036] The reaction temperature is quickly...

[0046] First prepare the water-based resin containing the hyperbranched structure, and prepare the raw materials according to the following components and the total fraction:

[0047]

[0048] Add the deionized water into the storage tank with stirring, pre-mix for 30 minutes under stirring, and inject it into the pipeline reactor with temperature regulating device at a rate of 3 liters per minute with a delivery pump with a flow meter. An initiator dripping device is installed at the monomer inlet of the reactor, and the initiator uses a 10% aqueous solution of ammonium persulfate.

[0049] While the monomer is being injected, the initiator is injected at a rate of 0.2 liters per minute in the first hour, and the reaction polymerization temperature is controlled at about 90°C. After the body is all injected from the mixing tank, the cooling water on the outer wall of the pipeline reactor is passed in, and the reaction temperature is quickly dropped to about 80°C, and the c...

Abstract

The invention discloses a water-based metal anti-corrosion coating which is characterized by comprising the following components in parts by weight: 50-75 parts of water-based resin containing a hyperbranched structure; 10 to 25 parts of deionized water; 8-10 parts of a coalescing agent; and 20-30 parts of a filler. The invention also discloses a preparation method and application of the compound. The water-based metal anti-corrosion coating is prepared by matching the water-based resin with the creative hyperbranched structure and the hyperbranched structure with a creative coating preparation process. The prepared water-based metal anti-corrosion coating has a rust transfer function, can be used for construction with rust on the surface of a steel structure, greatly reduces the difficulty of engineering construction and the labor intensity of workers, and has super-strong steel structure corrosion resistance in a C4 or even C5-M environment.

Description

technical field [0001] The invention relates to the field of preparation of antirust primers for steel structure metals, in particular to a water-based metal anticorrosion paint and its preparation method and application. Background technique [0002] Compared with oil-based anti-rust paint, water-based anti-rust paint does not contain harmful ingredients such as benzene, formaldehyde, etc., and will not contain these harmful chemicals to human health and the environment during production and processing. Serious environmental pollution and ecological damage are avoided, so in today's increasingly prominent environmental protection issues, the development and maturity of water-based industrial coatings is an inevitable trend. [0003] However, due to the limitations of current water-based resin technology, water-based industrial coatings are only used in general industrial fields. For heavy-duty anti-corrosion fields, especially C4 and above environments, such as marine engin...
