The invention relates to the technical field of corrosion inhibition, in particular to a composite corrosion inhibitor for an oil field pipeline and a preparation method of the composite corrosion inhibitor, and the composite corrosion inhibitor comprises an N-thiourea acetyl-ethoxylation modified imidazoline intermediate, a 2-pyridylaldehyde-diphenylamine-4-sodium sulfonate condensate, sodium cyanoboride and methanol. The preparation method comprises the following steps: carrying out cyclization, ethoxylation and thiourea acetylation on fatty acid and polyamine to prepare an N-thiourea acetyl-ethoxylation modified imidazoline intermediate, and dissolving the N-thiourea acetyl-ethoxylation modified imidazoline intermediate, 2-pyridylaldehyde, a diphenylamine-4-sodium sulfonate condensate and sodium cyanoboride in methanol according to a specific mass ratio to form the composite corrosion inhibitor. The technical problem that an oil field pipeline is poor in corrosion protection effect in a high-temperature, high-pressure, high-salinity and CO2 / H2S coexistence environment is solved, and synergistic and efficient corrosion prevention of multiple active components is achieved.

The application relates to the technical field of aluminum alloy wire manufacturing, and particularly discloses a high-strength heat-resistant aluminum alloy wire and a preparation method thereof; the high-strength heat-resistant aluminum alloy wire is composed of the following components in percentage by mass: Zr 0.1-0.2%, Fe 0.05-0.1%, Zn 0.01-0.03%, Si 0.06-0.1%, a doping substance 0.18-0.25%, the rest impurities 0.01-0.05%, and the rest is Al; the doping substance is composed of W2B and MoB2; the high-strength heat-resistant aluminum alloy wire provided by the application is optimized in the elements of zirconium (Zr), iron (Fe), zinc (Zn) and silicon (Si) and the doping substances W2B and MoB2; on the basis of maintaining good conductivity of the aluminum alloy wire, the heat resistance and tensile strength of the aluminum alloy wire are remarkably improved.

This invention relates to the field of composite material technology and discloses a crack-resistant and wear-resistant paint and its preparation method. The method includes pretreatment of fillers, preparation of modified resin matrix, grinding of dispersing aids, crosslinking and curing stages, and aging treatment. By plasma activation treatment of ceramic microspheres, the surface activity of the filler is enhanced, and its interfacial compatibility with the resin matrix is ​​improved, avoiding early cracking of the coating due to poor interfacial bonding. At the same time, the activated filler and nano-alumina form a gradient-dispersed reinforcing network structure in the matrix, improving the overall density and wear resistance of the coating. A composite system of epoxy-modified acrylic resin and polyurethane prepolymer is used. Through the reaction of isocyanate curing agents with the active groups in the resin during the crosslinking and curing stage, a stable structure is formed, enhancing the toughness and adhesion of the paint film, thereby inhibiting cracking and peeling of the coating during use.
