Abstract

The invention relates to a novel oil-soluble corrosion inhibitor, which is prepared by the following method: 0.6 to 0.8 part of imidazoline corrosion inhibitor, 0.0008 to 0.0012 part of quaternary ammonium salt, 0.4 to 1.1 parts of adsorption film type additive, 0.3 to 0.9 part of organic additive and 0.5 to 0.9 part of active agent. The adsorption film type additive is formed by mixing and stirring 0.1-0.3 part of tallow amine, 0.2-0.4 part of hexadecylamine and 0.1-0.4 part of octadecylamine, the mixing and processing temperature is 30-60 DEG C, 0.4-1.1 parts of the adsorption film type additive and 0.0008-0.0012 part of quaternary ammonium salt are mixed and stirred for 2 minutes at the speed of 30-80 revolutions per minute to obtain the stable adsorption additive, and the processing temperature is 40-50 DEG C. According to the novel oil-soluble corrosion inhibitor, the action effect of the corrosion inhibitor can be improved by adding the adsorption film type additive, adverse factors such as low activity and precipitation of the adsorption film type additive along with the change of time are prevented, and when the organic additive is added, the corrosion inhibitor can be used as an ideal corrosion inhibitor for nonferrous metals (especially copper), so that the service life of the corrosion inhibitor is prolonged. And the method has wider adaptability and practicability.

Description

technical field [0001] The invention relates to the technical field of corrosion inhibitors, in particular to a novel oil-soluble corrosion inhibitor. Background technique [0002] Chemical substances or compounds that can prevent or slow down the corrosion of materials when present in the environment (medium) in an appropriate concentration and form, so corrosion inhibitors can also be called corrosion inhibitors, and their dosage is very small (10-20ppm) , but the effect is significant, this method of protecting metals is called corrosion inhibitor protection. [0003] The existing corrosion inhibitor has a relatively single type of solvent in its formula, which leads to a relatively monotonous function of the corrosion inhibitor, and does not have stronger adaptability and better practical performance, and the mode of action of the corrosion inhibitor is also relatively monotonous. As a result, it cannot be applied to the items to be treated with different corrosion inhi...
