Abstract
The invention discloses base oil for a three-layer protection system for a steel pipe pile of an ocean platform, and belongs to the technical field of the protection of steel pipe piles of ocean platforms. The base oil comprises the following components in part by weight: 1 part of petroleum resin, 0.1 to 0.3 part of liquid chlorinated paraffin, 0.01 to 0.03 part of sorbitan monooleate, 0.01 to 0.04 part of 2,6-di-tert-butyl-p-cresol, 0.01 to 0.04 part of fumed silica, 0.1 to 0.5 part of kaolin, 0.1 to 0.5 part of precipitated barium sulfate and 0.1 to 0.5 part of talcpowder. When used, the base oil is directly spread to the surface of the steel pipe pile to form a base oil film, then a second-layer anticorrosive cold winding tape of the three-layer protection system is wound, and finally an outer-layer protective sleeve is arranged. The invention has the advantages that: the base oil has hydrophobic and corrosion inhibition functions, has the properties of good adhesion and the like, has excellent underwater constructability and storage stability, and is a key composing part of realizing the three-layer protection of the steel pipe piles of the ocean platforms; and the production process is simple.
Description
Technical field
The present invention relates to ocean platform steel pipe piling surface protection technique field, particularly the paint of ocean platform steel pipe piling protection is a kind of end oil that is exclusively used in the three-layer protection of steel pipe piling surface.Its end oil film has hydrophobic and corrosion inhibitive function, has good bonding force.
