Highly wear-resistant plant genetic lubricant oil additive, preparation method and application thereof

Abstract

A highly wear-resistant plant genetic lubricant oil additive, a preparation method and an application thereof are disclosed. The additive includes 90-97% of a plant base oil and 3-10% of an aerogel. The plant base oil is prepared from a mixed plant oil of soybean oil, rapeseed oil, sesame oil, peanut oil, olive oil, castor seed oil, salad oil, sunflower seed oil and tung oil. The highly wear-resistant plant genetic lubricant oil additive is added to various lubricant oils for being used to devices, and a colloidal substance is generated after the devices are driven and heat is generated, so that the lubricant oils are firmly adhered to the surface of components. The lubricant oil additive not only has characteristics of high abrasion resistance, high and low temperature resistance, and oxidation resistance, but also the used lubricant oil can be regenerated and recycled after being recovered and filtered.
