Abstract

The invention discloses plant oil-modified self-emulsifying ester. The plant oil-modified self-emulsifying ester is prepared from plant oil, vinyl diacid and fatty alcohol ether. The invention also discloses a preparation method of the plant oil-modified self-emulsifying ester. The preparation method comprises Diels-Alder reaction: adding plant oil, vinyl diacid (acid anhydride) and a certain amount of a catalyst into a reactor, and heating the materials to a certain temperature for double bond rearrangement and Diels-Alder reaction lasting for some time to obtain reacted plant oil, and esterification reaction: mixing the obtained reacted plant oil and fatty alcohol ether, adding a catalyst into the mixture, and heating the mixture to a certain temperature for some time to obtain a self-emulsifying ester finished product. The plant-based modified product is renewable, is biodegradable easily and prevents environmental pollution. The product has good lubrication performances and self-emulsifying characteristics, can be easily emulsified in water, can be used as an emulsifier for replacing other types of emulsifiers, an oil-based lubricant, an antirust agent and mineral oil or reducing their use in a water-based metal processing liquid.

Description

Technical field [0001] The invention relates to the field of self-emulsifying esters, in particular to a vegetable oil-modified self-emulsifying ester and a preparation method thereof. Background technique [0002] At present, the main emulsifiers used in the metalworking fluid industry are sodium petroleum sulfonate, vegetable oleic acid amine soap or inorganic alkali soap, nonylphenol polyoxyethylene ether, C10-14 fatty alcohol polyoxyethylene ether, oleyl alcohol ether, and vegetable fatty acid. Amides, etc.; lubricants are mainly fatty acid esters, fatty acid amine salts, etc., but sodium petroleum sulfonate is mainly derived from petroleum, which is not renewable and has poor biodegradability. Vegetable oleic acid amine soap or inorganic alkali soap has disadvantages such as large foam and not resistant to hard water. Nonylphenol polyoxyethylene ethers have been banned for use in metalworking fluids due to their huge impact on the environment. C10-14 fatty alcohol ethers ha...
