Engine oil composition taking waste plastic oil as fuel

Abstract

The invention discloses an engine oil composition taking waste plastic oil as a fuel. By adopting caster oil polyethylene glycol sebacate and poly alpha-olefin as base oil, matched with various compound additives, the engine oil composition comprises an antiwear agent, an antioxidant preservative, an anti-foaming agent, a viscosity index improver, a metal deactivator, a clearing agent, a dispersant, an antioxidant and an enhancer. The engine oil composition disclosed by the invention has excellent cleaning and dispersing effect, viscosity-temperature characteristic, base number retentivity and acid neutralizing capacity and can inhibit generation of polar materials such as oily sludge. The engine oil composition disclosed by the invention has good anti-high-temperature oxidation stability, halogen compound corrosion resistance and anti-nitration, antiwear, anti-shearing and antifriction and antiseptic properties, good low-temperature startability, low content of ash and less carbon deposit and is free from corrosion to moving parts.

Description

technical field [0001] The invention belongs to the field of internal combustion engine lubricants, in particular to an engine oil composition using waste plastic oil as fuel. Background technique [0002] Plastic has expansion, heat preservation, moisture barrier, toughness and corrosion resistance, and can replace various metal materials, wood materials and stone materials. It is an excellent and inexpensive material. But plastics themselves are difficult to biodegrade naturally, which is their fatal shortcoming. The ways to reuse waste plastics can be divided into two categories, namely raw material reuse and thermal processing reuse. The thermal processing and reuse of plastics is also called plastic recycling. Collect plastic waste and obtain gasoline and diesel fraction liquid fuel through thermal cracking, which not only reduces the environmental pollution caused by waste plastic, but also saves resources and turns waste into treasure. The technology of producing ...
