Abstract

The invention discloses a water-based heavy-duty anti-corrosion primer and a preparation method thereof, and belongs to the technical field of coatings and preparation methods thereof. According to the water-based heavy-duty anti-corrosion primer and the preparation method thereof, the formula system of the water-based heavy anti-corrosion primer comprises the aluminum alloy powder, the basalt fiber powder, the anti-rust pigment, the water-based epoxy resin emulsion, the water, the sterilization preservative and the hydrophilic epoxy curing agent, and the aluminum alloy powder is adopted, so that the overall anti-corrosion efficiency of the water-based heavy anti-corrosion primer can be improved; because of the addition of aluminum alloy powder, the content of zinc in the water-based heavy-duty anti-corrosion primer is greatly reduced, and the cost of the water-based heavy-duty anti-corrosion primer is also greatly reduced. The aluminum alloy powder is at least one of aluminum-copper alloy powder and aluminum-zinc-manganese alloy powder, the potential difference of zinc and manganese in the aluminum-copper alloy powder and the aluminum-zinc-manganese alloy powder is small, the generated electrochemical reaction is small, corrosion resistance is achieved, and the service life of the water-based heavy-duty anti-corrosion primer can be prolonged by adding the aluminum alloy powder into the water-based heavy-duty anti-corrosion primer.

Description

technical field [0001] The invention relates to the technical field of coatings and preparation methods thereof, in particular to a water-based heavy-duty anti-corrosion primer and a preparation method thereof. Background technique [0002] Heavy-duty coating refers to a type of anti-corrosion coating that can be used in relatively harsh corrosive environments and has a longer protection period than conventional anti-corrosion coatings. It includes primers, intermediate layers and surfaces. Paint matching paint. Heavy-duty anti-corrosion has two meanings, one is that the corrosion environment is harsh; the other is that the protection life is long, such as heavy-duty anti-corrosion coatings can be used for at least 10 years in the marine environment and chemical atmosphere; and in acid, alkali, salt and solvents Medium, and under certain temperature conditions, it can usually be used for more than 5 years. Therefore, coatings that can meet heavy-duty anti-corrosion require...
