THE EFFECT OF BUTYL METHACRYLATE AND ACRYLAMIDE COPOLYMER ON A UNIVERSAL-PURPOSE LUBRICANT BASED ON USED AVIATION OILS

Abstract

The article presents the results of studies on the effect of butyl methacrylate-acrylamide copolymers on universal lubricants based on waste motor and industrial oil. The physicochemical properties of lubricants based on the used industrial oil I-40A, synthetic oil Turbonicoil-321 were studied and certain results were obtained. It was found that adding the copolymer to the lubricant improves its quality characteristics. At the same time, waste aviation motor oils are not used as waste, but are processed into nanosized lubricants by interacting with various thickeners, oxidized cottonseed oil, rosin and copper acetate at a certain temperature and pressure. This is also of great environmental importance. The article reflects the properties and areas of application of highquality grease obtained as a result of the effect of acrylamide-butyl methacrylate copolymer on the resulting grease. The presence of synthetic oil in the base oil allows the grease to have a wider range of applications. In this case, maintaining its stability under vacuum, high pressure and temperature conditions, as well as high hermeticity, is of great importance. The article includes a graph demonstrating the high content of DDT in a propellant with the addition of a polymer. After the interaction of a lubricant obtained from waste semi-synthetic aviation motor oil with a copolymer of acrylamide BMA, a lubricant is obtained that differs from other industrial lubricants in its quality, plasticity and adhesive properties, which is described in detail in the article. This copolymer increases the resistance of lubricants to oxidation and improves their thermal stability.
