The invention discloses a composite acid
pickling corrosion inhibitor of barbadosnut cake
meal extract and a preparation method of the composite acid
pickling corrosion inhibitor, and belongs to the technical field of
corrosion inhibitors. The process of extracting an
acid corrosion inhibitor from barbadosnut cake
meal is optimized, toxalbumin and
phorbol ester are removed, the problem that the
acid corrosion inhibitor extracted from the barbadosnut cake
meal is toxic is solved, shaddock peel extract and the barbadosnut cake meal extract suffer from synergistic interaction, the corrosion inhibition efficiency is high, high adaptability is achieved, the effect of corrosion of acid on steel and aluminum is obviously inhibited, and more importantly, a good corrosion inhibition effect is achieved for
zinc and
zinc and aluminum
alloy. The
corrosion inhibitor is safe, free of harm, biodegradable and convenient to use, can be applied to washing
petrochemical equipment, boilers and even
tap water pipelines, and has good development prospects.
