Water-based self-drying anti-corrosion primer for engineering cranes and preparation method thereof

Abstract

The invention discloses a water-based self-drying anti-corrosion primer for engineering cranes and a preparation method thereof. The primer is composed of resin, auxiliary agent, thickening thixotropic agent, antirust pigment, silicon dioxide and auxiliary materials. For: resin: 10-30%, additives: 25-45%, thickening thixotropic agent: 2-15%, anti-rust pigment: 0.8-6%, silicon dioxide: 2-4%, auxiliary materials: 15- 25%; the preparation method of the water-based self-drying anti-corrosion primer is carried out according to the following steps: step (1): mix the resin and the auxiliary agent in a ratio of 4:6; step (2): put the above resin and the auxiliary agent into the stirring Stir and disperse in the kettle at a stirring speed of 400-700r / min; Step (3): Add all the configured thickening thixotropic agent, antirust pigment and silicon dioxide into the stirring kettle and stir evenly; Step (4): Finally, add auxiliary materials and stir for 40-55 minutes.

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...

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 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
