Abstract

The invention belongs to the field of paint manufacturing, and especially relates to a superfast-drying, anti-adhesion, and anticorrosion paint for casting pipes. The paint is characterized by comprising thermoplastic acrylic resin liquid, petroleum resin liquid, modified polyurethane resin, dispersant, bentonite, iron black, barite powder, xylene, cobalt naphthenate, chlorinated paraffin, and levelling agent. Compared with the conventional paint, the provided paint has the characteristics that the paint can be dried at a room temperature, and the drying speed is quick. The energy is saved and the consumption is reduced. The requirements of fast coating can be met. The paint can be sprayed on products at a room temperature, after 30 minutes the products can be piled together, and the products will not be adhered to each other. The processed products are suitable for streamline operation, the products are knocked with each other, the coating will not be damaged, and thus the problems of coating aging and cast pipe rusting due to outdoor storage and ocean transportation are solved.

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...
