Corrosion resistant ultraviolet (UV) curing paint for oil steel pipe and preparation method thereof

Abstract

The invention belongs to the technical field of corrosion resistant paint, and particularly relate to corrosion resistant UV curing paint for an oil steel pipe and a preparation method thereof. The UV curing paint comprises, by mass, 10%-30% of aliphatic polyurethane acrylate, 5%-20% of modified epoxy acrylate, 10%-30% of polyester acrylate, 20%-40% of monofunctional monomer, 8%-20% of bifunctional monomer, 2%-15% of multifunctional monomer, 5%-20% of abrarsion resistant agent, 2%-8% of photoinitiator, 0.1%-1% of leveling agent, 0.2%-2% of defoaming agent and 0.1%-1% of anti-settling agent. The UV curing paint has the advantages that the corrosion resistant coating efficiency and surface corrosion resistance of steel products are improved; the producing process is simple; a formed paint film has good adhesion, abrasion resistance, salt spray resistance and humidity resistance; and the UV curing paint can be applied to the steel products and is suitable for a plurality of coating modes such as spray coating and curtain coating.

Description

technical field [0001] The invention belongs to the technical field of anti-corrosion coatings, and in particular relates to an anti-corrosion UV paint for petroleum steel pipes and a preparation method thereof. Background technique [0002] Petroleum steel pipes occupy an important position in the petroleum industry, not only in terms of huge output, but more importantly, the quality and performance of steel pipes are of great importance to the development of the petroleum industry. Petroleum steel pipes mainly include oil well pipes (drill pipes, drill collars, casings, oil pipes, etc.) and paint delivery pipes. In general, compared with the surface treatment of ordinary steel pipes, the surface treatment of petroleum steel pipes, especially the task of anti-corrosion, is more difficult. The main reasons are as follows: On the one hand, due to the huge annual output of petroleum steel pipes, some may face the need for long-term storage, and some It may need to go through ...

AI Technical Summary

Problems solved by technology

In general, when UV paint is applied to the surface of steel for surface anti-corrosion function, due to the presence of an oxide film on the metal surface, the surface energy of the metal is reduced, the adhesion of UV paint is poor, and the coating is difficult.
