Description
Technical field
The invention belongs to the anti-corrosive paints technical field, be specifically related to a kind of petroleum steel pipe with anticorrosion UV lacquer and preparation method thereof.
Background technology
Petroleum steel pipe occupies an important position in petroleum industry, and it is huge not only to show as output, and main is that development counts for much to petroleum industry for pipe quality, performance.Petroleum steel pipe mainly comprises oil well pipe (drilling rod, drill collar, sleeve pipe, oil pipe etc.) and paint transfer lime two big classes.Generally, with respect to the surface treatment of common steel tube, petroleum steel pipe is in surface treatment; Task on particularly anticorrosion is arduous more, and its major cause is following: on the one hand, and petroleum steel pipe; Because its annual output is huge, a part possibly face needs standing storage, and a part possibly need experience long-distance transport process; Be vulnerable to the influence of media such as atmosphere, industrial gasses, salt fog, acid rain and trickle and produce corrosion; And, in cargo handling process, also very easily cause outside damage such as wearing and tearing, scratch, thereby influence the performance of petroleum steel pipe; On the other hand, because petroleum steel pipe in use, working condition is abominable, mostly is in the environment of high temperature and harsh corrosive medium.
The actual requirement that traditional rust-inhibiting paint is weather-proof, scratch resistance, corrosion resistance nature all can not be satisfied the client; And traditional rust-inhibiting paint also exists, and rate of drying is slow, production efficiency is low, solvent evaporates produces problems such as environmental pollution, needs a kind of novel product badly it is substituted.UV lacquer, i.e. ultraviolet light polymerization lacquer is to be the environment-friendly and energy-efficient coating of characteristic to adopt radiation curing technology; Its staple is photosensitive resin, reactive thinner, light trigger and auxiliary agent; This coating is under the irradiation of the UV-light of certain wavelength, and the light trigger absorbing ultraviolet light in the coating can form radical, causes photosensitive resin and reactive thinner molecule; And then polymerization, crosslinking reaction take place, make paint solidification.Compare with traditional coating, advantages such as UV lacquer has that saving power and preventing pollution dyes, ambient cure, efficient and superior performance are widely used in fields such as chemical industry, machinery, electronics, light industry.Generally speaking, UV lacquer is coated on steel surface when being used for the surface anticorrosion function, because there is layer oxide film in the metallic surface, thereby causes the metallic surface can reduce, the sticking power that UV coats with lacquer is relatively poor, and application is difficult.
