Paragraph 0044, (2018/09/12)
The invention discloses an acidification corrosion inhibitor based on an interpolymer indolizine derivative as well as a preparation method and application thereof. The acidification corrosion inhibitor contains the interpolymer indolizine derivative; the interpolymer indolizine derivative is prepared by carrying out decarboxylation on heterocyclic alkali including (substituted) quinoline, (substituted) pyridine and the like, and carboxymethyl heterocyclic alkali quaternary ammonium salt obtained by alpha-haloacetic acid, and then carrying out intermolecular addition polymerization reaction onquaternary ammonium salt of the heterocyclic alkali including the (substituted) quinoline, the (substituted) pyridine and the like. The acidification corrosion inhibitor disclosed by the invention has relatively good corrosion inhibition performance under the condition that common corrosion inhibition synergists including alkynol and the like do not need to be compounded; the use amount of the acidification corrosion inhibitor is less and the acidification corrosion inhibitor can reach, even be better than the requirements of an acidification corrosion inhibitor performance testing method andfirst-grade to third-grade standards in evaluation indexes SY/T 5405-1996 when being independently used.
