Problems solved by technology

It can be seen that the current water-based anti-corrosion coatings have poor corrosion resistance, initial water resistance and mechanical properties, and the paint film cannot be cured at room temperature, and the construction adaptability is low. Therefore, it cannot be applied to anti-corrosion coatings on the surface of engineering cranes.

Abstract

The invention discloses a room-temperature-curable aqueous anticorrosion primer used for coating the external surface of a construction crane. The primer comprises the following components by weight: 35-45% of an aqueous resin, 5-8% of a curing agent, 1-3% of a dispersant, 5-12% of an antirust pigment, 20-35% of a pigment filling material, 1-2% of an anti-settling agent, 0.5-1% of a wetting agent, 0.5-1% of a thixotropic agent, 0.5-1% of an antifoaming agent, 0.1-0.8% of a flash etching inhibitor, 0.1-0.8% of a mildew inhibitor, 1-3% of a film-forming auxiliary agent and 10-20% of deionized water. The invention also discloses a preparation method of the aqueous anticorrosion primer. The aqueous anticorrosion primer has a room-temperature-curable paint film, is energy-saving and environment friendly, and can satisfy safe production requirements of enterprises; the primer is high in solidity, low in viscosity, convenient for construction; and the coating of the primer has good corrosion resistance and water proofness, and the comprehensive properties of the coating reach performance indexes of same-type oiliness products.

Description

technical field [0001] The invention relates to a water-based paint, in particular to a room-temperature-curable water-based anticorrosion primer for coating the outer surface of an engineering crane. The invention also relates to a preparation method of the water-based anticorrosion primer. Background technique [0002] Engineering cranes are mainly divided into port cranes, construction cranes, general factory cranes and other mobile cranes. According to different application environments, there are different standards for anti-corrosion requirements. At present, the anti-corrosion primers for domestic engineering crane equipment generally use solvent-based alkyd primers, epoxy ester primers, polyurethane primers, two-component epoxy iron red paint, and epoxy zinc-rich primers. The environment is harsh, and the content of organic volatile gases in the air is high. Due to the large area occupied by engineering cranes, it is impossible to set up a separate spraying workshop...
