This invention relates to the field of lubricant preparation technology and provides a method for preparing a neutralization-free modified amine ethoxylated compound lubricant. The method includes the preparation of oligomeric amides and alkoxylated adducts. An oligomer is formed by condensing a dimer acid with diethylenetriamine to form an amide. Subsequently, the oligomer is modified with ethylene oxide and propylene oxide, alkoxylating the secondary amino groups in the diethylenetriamine. The alkoxylated secondary amino groups act as an alkaline neutralizer, while the dimer acid replaces the fatty acid as a lubricant. By adjusting the ethylene oxide-propylene oxide ratio and polymerization structure, products with emulsifying functions for semi-synthetic cutting fluids and low-foaming products for fully synthetic cutting fluids can be synthesized. This reduces preparation costs and environmental pollution, and allows for the preparation of high-performance adducts suitable for different application areas. It also improves product quality and stability, resulting in a promising market.
