Abstract

The invention discloses a 2-chlorinized,3-polyhydroxypropyl isopropylamine quaternary ammonium salt surfactant-containing corrosion inhibitor. The corrosion inhibitor can be applied to an aluminum alloy corrosion inhibition system for aviation; and a 2-chlorinized,3-polyhydroxypropyl isopropylamine quaternary ammonium salt surfactant can be independently used as a corrosion inhibitor, or the 2-chlorinized,3-polyhydroxypropyl isopropylamine quaternary ammonium salt surfactant can be combined with sodium dodecyl benzene sulfonate or cerium chloride heptahydrate. An experiment shows that compared with the corrosion inhibition capacity of a corrosion inhibitor independently taking a synthesis raw material isopropamide, the corrosion inhibition capacity of the corrosion inhibitor is improved to different extends, and a corrosion inhibition system is outstanding in synergistic effect; and the corrosion inhibitor has wide application value.

Description

technical field [0001] The invention belongs to the technical field of fine chemicals, in particular to a corrosion inhibitor containing 2-chlorinated and 3-polyhydroxypropylisopropylamine quaternary ammonium salt surfactant. technical background [0002] Because aluminum and aluminum alloy materials have the advantages of low density (about 2.7g / cm3), high specific strength, good electrical conductivity and thermal conductivity, and easy processing and casting, they are widely used in aerospace, transportation, light industrial building materials, electronic information, machinery, etc. It has a broad application prospect and an irreplaceable important position in the packaging industry. Among them, 2024 aluminum alloy is a kind of high-strength hard aluminum alloy widely used in aircraft, which has good mechanical and processing properties, but 2024 aluminum alloy contains more copper, resulting in poor corrosion resistance. Corrosion is very easy to occur in the environm...
