High-performance water-based paint for medium and small mechanical equipment and preparation method thereof

Abstract

The invention discloses a high-performance water-based paint for medium and small mechanical equipment, which comprises the following components in percentage by weight: 35-45% of water-based resin, 8-15% of full methylated amino resin, 2-8% of dispersant, 1-5% of pigment, 0.5-1% of wetting and leveling agent, 0.5-1% of thixotropic agent, 0.5-1% of defoaming agent, 0.1-0.8% of flash etching inhibitor, 0.1-0.8% of mildew inhibitor, 1-5% of film forming assistant and 30-40% of deionized water. The invention also discloses a preparation method of the high-performance water-based paint. The high-performance water-based paint has the characteristics of water dilution property, energy saving, environmental protection and the like, and is convenient for construction; the coating has the advantages of high aging resistance, solvent resistance, moisture and heat resistance, high gloss, high fullness and favorable mechanical properties; and the properties of the paint film achieve or exceed those of similar type oil-based products.

Description

technical field [0001] The invention relates to a chemical paint, in particular to a water-based paint used for small and medium mechanical equipment, and also to a preparation method of the paint. Background technique [0002] my country is far behind the international advanced level in terms of high-performance coating water-based technology. High-performance water-based coatings have an absolute advantage in industrially developed countries. Most of the machinery in Western Europe adopts water-based coating; in the United States, Japan and other countries, it is as high as 40-50%, but at present, my country's water-based coating only accounts for 15% in the field of industrial coating, mainly concentrated in the manufacture of foreign-funded brand passenger cars. [0003] Domestic enterprises that produce water-based high-performance coatings for machinery and equipment are mainly internationally renowned companies such as BASF, Nippon Paint, and PPG. Their output accoun...

AI Technical Summary

Problems solved by technology

Since the manufacturing process, coating quality requirements and processes of mechanical equipment and passenger cars are quite different, and the product types are also different, it cannot be applied

At present, the domestic self-sufficiency rate of water-based coating for mechanical equipment is less than 10%, which is mainly concentrated in the application fields with low requirements such as mechanical chassis and the manufacture of primers such as primer electrophoresis, while the high-performance, The composite coating technology with high decorative requirements has not been widely used, especially the water-based high-performance coating technology that meets the requirements of REACH has not been reported
