Abstract

The invention discloses an organic corrosion inhibitor suitable for an antifreezing solution, which comprises the following components by weight: 20-30 parts of organic acidity and its salt, 10-13 parts of amide, 6-9 parts of nitrogen heterocyclic ring, 3-5 parts of solid state alkali, 4-7 parts of organic copolymer and 5-20 parts of water. Compared with prior art, the organic corrosion inhibitor added in the antifreezing solution plays good corrosion delaying effect, stability and foaming characteristic can satisfy the requirement of real usage, and all components in a formula are nontoxic or low-toxicity components, and the components have the advantages of low cost and easy acquisition.

Description

technical field [0001] The invention belongs to the field of antifreeze, and in particular relates to an organic corrosion inhibitor suitable for antifreeze. Background technique [0002] In the research field of antifreeze (also known as coolant) for vehicles, because the research on antifreeze has matured, the main difference of antifreeze lies in the different formulations of corrosion inhibitors. General antifreeze is divided into inorganic antifreeze, inorganic-organic antifreeze and all organic antifreeze according to the difference of corrosion inhibitor additives. Antifreeze with all-organic corrosion inhibitors is characterized by being able to be used stably for 3 years or even longer, reducing maintenance and waste liquid discharge, so it is becoming more and more popular, but the current formula of all-organic antifreeze is less, And there are the disadvantages of high price and high toxicity. Contents of the invention [0003] Purpose of the invention: the p...
