Novel oil soluble corrosion inhibitor

Abstract

The invention relates to a novel oil soluble corrosion inhibitor. The preparation method of the novel oil soluble corrosion inhibitor comprises the steps of mixing and stirring the components of 0.6-0.8 part of imidazoline corrosion inhibitor, 0.0008-0.0012 part of quaternary ammonium salt, 0.4-1.1parts of adsorption film additive, 0.3-0.9 part of organic additive, 0.5-0.9 part of an active agent,and mixing 0.4-1.1 part of the adsorption film additive and 0.0008-0.0012 part of quaternary ammonium salt and stirring the mixture for 2 minutes (at the speed of 30-80 rpm) at the processing temperature of 40-50 DEG C to obtain a stable adsorption additive, wherein the adsorption film additive is formed by mixing and stirring 0.1-0.3 part of tallow amine, 0.2-0.4 part of hexadecylamine and 0.1-0.4part of octadecylamine at the mixing processing temperature of 30-60 DEG C. The novel oil soluble corrosion inhibitor can increase the action effect of the corrosion inhibitor by adding the adsorption film type additive, and prevent occurrence of unfavorable factors such as low activity, precipitation and the like of the adsorption film additive along with the change of time; and when the organic additive is added, the corrosion inhibitor can be used as an ideal corrosion inhibitor for nonferrous metals (especially copper) and 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] When present in the environment (medium) in an appropriate concentration and form, chemical substances or compounds that can prevent or slow down the corrosion of materials, so corrosion inhibitors can also be called corrosion inhibitors, and their dosage is very small (10-20ppm) , but the effect is remarkable. This method of protecting metals is called corrosion inhibitor protection. [0003] The type of solvent contained in the formula of the existing corrosion inhibitor is relatively single, which leads to the monotonous function of the corrosion inhibitor, which does not have stronger adaptability and better practical performance. At the same time, 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 dif...

Problems solved by technology

[0004] The purpose of the present invention is to provide a novel oil-soluble corrosion inhibitor to solve the problem that the formula of the existing corrosion inhibitor proposed in the above-mentioned background technology contains a single type of solvent, which causes the function of the corrosion inhibitor to be relatively monotonous and does not have Stronger adaptability and better practical performance, and the mode of action of the corrosion inhibitor is relatively monotonous, which makes it impossible to apply to the items to be treated with different corrosion inhibition methods
