Waterborne self-drying anticorrosion priming paint for construction crane and preparation method thereof

Abstract

The invention discloses a waterborne self-drying anticorrosion priming paint for a construction crane and a preparation method thereof. The priming paint comprises, by weight, 10 to 30% of a resin, 25 to 45% of an auxiliary agent, 2 to 15% of a thickening thixotropic agent, 0.8 to 6% of an antirust pigment, 2 to 4% of silica and 15 to 25% of an auxiliary material. The preparation method for the waterborne self-drying anticorrosion priming paint comprises the following steps: step (1), mixing the resin and the auxiliary material according to a ratio of 4: 6; step (2), putting the resin and the auxiliary material into an agitator for stirring and dispersing, wherein a stirring speed is 400 to 700 r / min; step (3), adding the prepared thickening thixotropic agent, antirust pigment and silica into the agitator for uniform mixing under stirring; and step (4), adding the auxiliary material and carrying out stirring for 40 to 55 min.

Description

technical field [0001] The invention relates to a self-drying anti-corrosion primer and a preparation method thereof, in particular to a water-based self-drying anti-corrosion primer for engineering cranes and a preparation method thereof. Background technique [0002] 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 primers, and epoxy zinc-rich primers. Harsh, high VOC content in the air. Due to the large area occupied by engineering cranes, it is impossible to set up spraying workshops and drying rooms alone. Therefore, domestic production companies usually put welding and spraying in the same room, which poses serious flammable, explosive and health hazards. Domestic enterprises that produce water-based high-performance primer materials for machinery and equipment are mainly internationally renowned companies such as BASF, NIPP...

AI Technical Summary

Problems solved by technology

Due to the large area occupied by engineering cranes, it is impossible to set up spraying workshops and drying rooms alone. Therefore, domestic production companies usually use welding and spraying in the same room, which poses serious flammable, explosive and health hazards.

Domestic enterprises that produce water-based high-performance primer materials for machinery and equipment are mainly internationally renowned companies such as BASF, NIPPON, and PPG. Their output accounts for about 90% of the total production of domestic industrial water-based high-performance primer materials, all of which are used for passenger cars. Due to the different construction techniques, it cannot be applied to the coating of engineering cranes. At present, domestic water-based technologies that meet the needs of construction machinery equipment are mainly concentrated in the application fields with low requirements such as mechanical chassis and the manufacture of primers such as primer electrophoresis, while high-performance The required waterborne anti-corrosion coating technology has not yet been applied
