Abstract

The present invention relates to a non-sulfur and non-phosphorus water-soluble organic boron additive. The technical scheme of the present invention is that: the preparation method comprises the following steps: placing oleic acid and diethanolamine in a container, carrying out a reaction for 3-5 hours at a temperature of 90-100 DEG C, adding hydroxyethylethylene diamine, and continuously carrying out the reaction for 2-4 hours at the temperature of 100 DEG C under a vacuum condition to obtain mixed oleyl amine, wherein a weight ratio of the oleic acid to the diethanolamine is 100:30-40, a weight ratio of the oleic acid to the hydroxyethylethylene diamine is 100:20-30; mixing the prepared mixed oleyl amine and boric acid, uniformly stirring, then adding imidazole, reducing the pressure to 100-150 mmHg at the temperature of about 70-80 DEG C, and carrying out the reaction for 4-5 hours; adjusting the temperature to 80-100 DEG C, reducing the pressure to 50-80 mmHg, and carrying out the reaction for 2-3 hours; sucking the moisture generated from the reaction; carrying out cooling and filtering to obtain the yellowish non-sulfur and non-phosphorus water-soluble organic boron with the content of 3.2% and the N content of 5.5%, wherein a weight ratio of the mixed oleyl amine to the boric acid is 100:20-30, and a weight ratio of the mixed oleyl amine to the imidazole is 100:15-20. According to the present invention, the two-step vacuum distillation treatment is adopted, and the prepared product has excellent extreme pressure property, good metal slow release and excellent water soluble lubrification.

Description

technical field [0001] The invention belongs to the field of chemical synthesis, and in particular relates to the synthesis of a nonthion-phosphorous water-soluble organic boron additive compound. Background technique [0002] Long-chain fatty acid water-based boron derivatives as a neutral aqueous solution medium, the application of steel corrosion inhibitors and cutting fluid application research has been the attention of scholars from all over the world. With the development and the further strengthening of people's awareness of ecological environment, more and more researchers are trying to use non-nitrous acid, non-sulfur phosphorus long-chain fatty acid amides to provide a chemical barrier to enhance the corrosion inhibition performance of the preparation. In particular, some water-soluble products can improve the anti-rust ability of the product by adding the compound of C12~C18 organic acid and alcohol amine. However, domestic research shows that improving its water...
