A kind of anti-corrosion coating for ultra-fast drying and anti-sticking cast pipe

Abstract

The invention belongs to the field of paint manufacturing, and in particular relates to an ultra-fast-drying anti-sticking cast pipe anticorrosion paint, which is characterized in that it comprises thermoplastic acrylic resin liquid, petroleum resin liquid, modified polyurethane resin, dispersant, bentonite, iron black, heavy Spar powder, xylene, cobalt naphthenate, chlorinated paraffin, leveling agent. Compared with the traditional paint coating used, the present invention has the characteristics of normal temperature drying, ultra-fast drying, etc., and has the advantages of energy saving and consumption reduction, etc., and meets the requirements of the rapid coating process; the product can be stacked and packaged without sticking after spraying at room temperature for 30 minutes, suitable for Assembly line operation, the paint film does not fall off when the stacking is bumped against each other, and after a certain period of time it is placed in the open air, the paint film is aging, and the cast pipe is rusted.

Description

technical field [0001] The invention belongs to the field of paint manufacture, and in particular relates to an ultra-fast-drying anti-sticking cast pipe anticorrosion paint. Background technique [0002] At present, iron cast pipes are widely used in the sewerage and industrial drainage pipes of large buildings and houses at home and abroad. Its application spreads all over the country and is directly related to industrial production and civil facilities. Since the exposed cast pipes will soon rust and corrode during open-air storage and transportation, it is generally used to protect the cast pipes by spraying paint after production to prevent the cast pipes from rusting and corroding, and prolong the use of steel cast pipes life. [0003] In China, the assembly line is usually used to coat steel cast pipes. Most of the methods are carried out in accordance with the procedures of heating and preheating the cast pipes after pretreatment, spraying anti-corrosion coatings, d...

AI Technical Summary

Problems solved by technology

The anti-corrosion coatings usually used are prone to brittle paint film and not resistant to bumps after being painted on the assembly line, and then placed in the open air for a certain period of time, aging of the paint film during ocean transportation, and rusting of cast pipes, etc.
