Abstract

The invention discloses a water-based ultrafast-drying anticorrosive coating for a petroleum steel pipe, and relates to the field of water-based industrial coatings. The preparation method comprises the following steps: firstly, terminating simethicone by using amino to prepare modified silicone oil; reacting the modified silicone oil with graphene oxide to prepare modified graphene / organic silicone oil; then reducing the mixture to prepare reduced modified graphene / organic silicone oil; then self-making water-based anti-corrosion coating, and adding zinc powder into the water-based anti-corrosion coating for modification; finally, reacting the reduced modified graphene / organic silicone oil with the modified anti-corrosion coating to prepare the water-based ultra-fast-drying anti-corrosion coating. The prepared water-based ultra-fast-drying anticorrosive paint for the petroleum steel pipe has the characteristics of short drying time, enhanced corrosion resistance, improved mechanical properties and the like.

Description

technical field [0001] The invention relates to the technical field of water-based industrial coatings, in particular to a water-based ultra-fast-drying anti-corrosion coating for petroleum steel pipes. Background technique [0002] Petroleum steel pipes mainly include oil drilling pipes, oil casing pipes, oil extraction pipes, etc. Newly produced steel pipes and factory refurbished steel pipes need to be coated with a layer of hard film anti-rust oil, which is also a layer of anti-corrosion coating. Currently, the commonly used oil steel pipe anti-corrosion paint Multi-purpose solvent-based anti-corrosion coatings, due to environmental protection requirements, need to use water-based anti-corrosion coatings for factory coating of steel pipe paint. The current water-based petroleum steel pipe paint generally has the problems of slow drying speed and serious corrosion. In today's industrialized production, some manufacturers can only rely on heating for drying, which not only...
