Problems solved by technology

[0009] The purpose of the present invention is to address the defects of existing cutting fluid additives in terms of anti-hard water, lubrication and rust prevention. The present invention provides a novel additive tall oleic acid diacetamide borate, which can guarantee low acid value. At the same time, it overcomes the defects that the cutting fluid itself is not resistant to hard water, and the lubricity and rust resistance in hard water are reduced.

Abstract

The invention relates to a tall oil acid diacetyl amide borate which is prepared from the following components in percentage by weight: 40-65% of tall oil fatty acid, 30-45% of diethanolamine, 3.2-12.5% of boric acid and 1.8-2.5% of catalyst. The invention also relates to a formula and preparation method of the tall oil acid diacetyl amide borate. The components proportionally react according to the steps to prepare the tall oil acid diacetyl amide borate. The tall oil acid diacetyl amide borate can be directly diluted and used as a cutting fluid in metal working. The product has the advantages of favorable lubricating property, favorable rust resistance and favorable hard water resistance.

Description

technical field [0001] The invention relates to tall oleic acid diacetamide borate and a preparation method thereof, belonging to the technical field of metalworking fluid additives. [0002] Background technique [0003] Cutting fluid is an industrial liquid used in metal cutting and grinding to cool and lubricate cutting tools and workpieces. Cutting fluid is composed of various additives. [0004] There are three types of cutting fluids, the first is oil-based cutting fluid containing mineral oil and additives, the second is glycol-based cutting fluid containing polypropylene glycol or polyethylene glycol as the main component, and the third is surface Aqueous cutting fluid in the form of an aqueous solution of active agent. [0005] The existing fatty acid diethanolamide borate has the following deficiencies in the configuration of water-based cutting fluids. First, the water used for dilution in most factories is not treated, and the hardness of the wa...
