Embodiment Construction

[0034] The present invention will be further described below in conjunction with examples.

[0035] First prepare carbon-titanium modified acrylic resin according to the following steps:

[0036] (1) Take the raw materials of the following quality:

[0037]

[0038]

[0039] (2) Put 2400g of deionized water, 500g of nano-carbon-titanium composite and 3g of ammonium bicarbonate into the reactor and stir to raise the temperature to 88°C;

[0040] (3) 2300g deionized water, 400g nano-carbon-titanium composite and 20g sulfosuccinate are dropped into the pre-emulsification kettle under agitation state and drop into all butyl acrylate, methyl methacrylate, styrene and acrylic acid, stir for 30 Take out after minutes;

[0041] (4) Add the mixed liquid of step (3) into the reaction kettle that has been heated to 88° C. and stir;

[0042] (5) remove 200g deionized water and 30g ammonium persulfate and make solution;

[0043] (6) half of the solution obtained in step (5) is pu...

Abstract

The invention discloses a water-based steel structural anti-corrosive coating. The water-based steel structural anti-corrosive coating is prepared from, carbon titanium modified acrylic resin, dispersing agent, wetting agent, pigment, filler, anti-foaming agent, anti-flash-rust agent, anti-sinking agent, coalescing agent, thickening agent, pH adjusting agent, fungicide, and de-ionized water. The water-based steel structural anti-corrosive coating can carry out construction along with rust, and has low requirement on construction environment, thus the coating labor intensity is largely reduced; especially, the coating has super-strong scratching self-repair ability, and the heavy anti-corrosive field needs not use the zinc-enriched primer, thus the environmental protection property and reliability of the heavy corrosion prevention are greatly increased. The water-based coating is applied to the heavy corrosion prevention, and the construction simplicity and corrosion prevention are better than the existed oily coating. The coating has very strong weather resistance, and can realize the long-term protection under the condition of thin coating thickness.

Description

technical field [0001] The invention belongs to the field of steel anticorrosion coatings, and in particular relates to a water-based steel structure anticorrosion coating and a preparation method thereof. Background technique [0002] In the environmental protection trend of oil-to-water transformation in the coatings industry, anti-corrosion coatings are a difficult field to overcome. 90% of the anti-corrosion industry uses oil-based paint, and 100% of the oil-based paint is used in the heavy-duty anti-corrosion field. [0003] Traditional oil-based anti-corrosion coatings have complex coating processes, harsh working conditions, and high labor intensity. Corrosion rings above C4 also need to add zinc-rich primer, which not only brings serious pollution to the environment, but also greatly increases the difficulty of construction. Due to the limited performance of the current anti-corrosion coatings, usually after 5 to 10 years of use, the base surface needs to be re-cle...
