Abstract

The invention belongs to the field of anti-corrosion technology of metal material, and more particularly relates to a magnesium alloy corrosion inhibitor and a preparation method thereof. The magnesium alloy corrosion inhibitor takes the mixture of ficus virens leaves, sweet osmanthus tree leaves and willow leaves as raw material, and is prepared by the steps of mixing the three leaves according to a certain weight proportion, cleaning the mixture, smashing, poaching, filtering, extracting, etc. The magnesium alloy corrosion inhibitor has the advantages of simple preparation method, environment protection, wide source of the raw material, little dosage of the product, high corrosion inhibition efficiency, low cost and changing waste into valuable, can be widely used for inhibiting the corrosion of magnesium alloy, and has good application prospect.

Description

technical field [0001] The invention relates to the technical field of anticorrosion of metal materials, in particular to a magnesium alloy corrosion inhibitor and a preparation method thereof. Background technique [0002] Magnesium alloys are known as "green engineering materials in the 21st century" and have broad application prospects in many fields such as automobiles, machinery, and aerospace. However, the corrosion resistance of magnesium alloy is very poor, and it is prone to corrosion in humid atmosphere or acidic, neutral, and weak alkaline solutions, which largely limits its performance advantages. Therefore, it is urgent to develop related anti-corrosion technology to improve its corrosion resistance and promote its application. [0003] Corrosion inhibitor technology can prevent or slow down the corrosion of metals, and is one of the most widely used metal corrosion protection technologies. Currently widely used magnesium alloy corrosion inhibitors include ino...
