Application of water metal-paint on special package steel tank

Abstract

The present invention is characterized by that the water metal paint can be spray-coated on the internal and external surfaces of steel barrel so as to produce the environment-protecting type coating light special packaging steel barrel, and the paint film quality of the environment-protecting steel barrel can completely meet the requirements for packaging steel barrel, and the quality of the steel barrel also can meet the packaging requirements for railway transportation and dangerous chemical cargo ocean transportation.

Description

Technical field: [0001] The invention relates to the application of a water-based metallic paint on special packaging steel drums. Background technique: [0002] Packaging steel drums are widely used in the packaging of petroleum, chemical, grain and oil industries. At present, domestic manufacturers use oily resin paint to spray steel drums. When using oil-based resin paint, due to the needs of the spraying process, it is necessary to use 20-40% of the paint volume to dilute with benzene-containing solvents. During the drying process, this part of the solvent will all become gas and evaporate into the air, causing Atmospheric pollution, at the same time, the operator's inhalation will affect the health of the operator, prone to occupational diseases, and there are safety hazards; the waste paint slag produced after the oversprayed paint settles also pollutes the environment. Although activated carbon and other adsorption methods can be used for waste gas treatment, the eff...

When using oil-based resin paint, due to the needs of the spraying process, it is necessary to use 20-40% of the paint volume to dilute with benzene-containing solvents. During the drying process, this part of the solvent will all become gas and evaporate into the air, causing Atmospheric pollution, at the same time, the operator's inhalation will affect the health of the operator, prone to occupational diseases, and there are safety hazards; the waste paint slag produced after the oversprayed paint settles also pollutes the environment

Although activated carbon and other adsorption methods can be used for exhaust gas treatment, the effect is limited and the pollution and safety issues cannot be completely solved.

[0003] Anti-corrosion coatings for special industrial tanks such as steel oil tanks have been researched and reported in the literature ("Packaging Engineering", 2002, 2003 (1-3)), these coatings are usually solvent-based resin paint products; suitable for steel surfaces The water-based rust coating has also been reported ("Metal Products", 2002, 2003 (1-2)), this type of coating is mainly used for rust prevention, rust removal and anticorrosion of steel plates or steel structures, and has not been seen in steel drums, etc. Application on packaging containers; there are also literature reports on water-based coating compositions for metal containers and their applications ("Coating Technology", 2002, (1-6)), and the reported applications are only limited to food or beverage containers. metal products
