Abstract
A biodegradable chain bar lubricant composition containing a blend of naturally occurring and partially hydrogenated vegetable oil triglycerides, which blend it can be adjusted for the lubricant composition an unusually low pour point to make it useful for cold weather applications, or a high lubricity at higher summer temperatures. The composition also contains additives including a viscosity modifying additive, a pour point depressant, a tackifier, a lubricity improver, and an anti-wear or anti-corrosion additive.
Claims9
A biodegradable chain saw bar lubricant composition comprising:
- (a) a blend of between one and ninety nine percent of one or more naturally occurring triglycerides and between ninety nine and one percent of one or more partially hydrogenated triglycerides, said naturally occurring triglycerides having an oleic content of at least 60% and said partially hydrogenated triglycerides having an oleic content of less than 50%;
- (b) between 2 and 10% of a viscosity modifying additive;
- (c) between 3 and 10% of a tackifier;
- (d) between 2 and 3% of a pour point depressant;
- and
- (e) between 1.5 and 5.0% of an anti-wear agent.
A BioLubricant composition comprising a blend of triglycerides having a ratio of mono to poly unsaturated content of between 0.5/1.0 to 0.98/1.0 in which said blend of triglycerides is formed by the partial hydrogenation of a vegetable oil, and said composition contains between 2 and 10% of a viscosity modifying additive, between 3 and 10% of a tackifier, between 2 and 3% of a pour point depressant, and between 1.5 and 5.0% of an anti-wear agent.
