Abstract

The invention relates to an ultraviolet curing anti-drag paint in steel pipes. Epoxy acrylate and polyester acrylate are combinedly used as prepolymers, and phosphate-modified acrylate resin is used as an adhesion promotor, thereby greatly increasing the adhesion; a mixture of two or three of tripropylene glycol diacrylate, isobornyl acrylate and ethoxylated trimethylolpropane triacrylate is selected as an active monomer, and multiple functional group monomers are selectively added for compounding, thereby simultaneously satisfying curing speed, hardness, adhesion, flexibility and other requirements; multiple initiator compounding systems are adopted so as to simultaneously implement curing on the surface layer and deep layer; the paint provided by the invention has favorable mechanical properties and chemical resistance on a steel substrate; after coating, the surface is very smooth, has favorable anti-drag effect, can effectively enhance the salt fog resistance and corrosion resistance of the coating and the transmission efficiency of the pipeline, and can be widely used in anti-drag corrosion prevention in transmission pipelines in the fields of oil transmission, gas transmission, water supply and drainage, and the like.

Description

technical field [0001] The invention relates to the technical field of coatings in chemical technology, and relates to an ultraviolet light-cured coating and an internal drag-reducing coating for steel pipes, in particular to an ultraviolet-curable internal drag-reducing coating for steel pipes. Background technique [0002] As a new material that began to rise in the 1970s, UV-curable coatings have the outstanding advantages of fast curing speed (0.1-10s); excellent coating performance; they can be coated on heat-sensitive substrates; energy saving (approx. It is 1 / 5-1 / 10 of the energy consumption of heat-curing materials); no solvent is discharged, it is safe and does not pollute the environment; it occupies a small area and is suitable for automatic assembly line coating, etc. Therefore, UV-curable coatings are increasingly widely used. [0003] UV curable coating refers to a special coating that can undergo photopolymerization or photocrosslinking reaction under ultravi...
