The present invention relates generally to a composition of a viscoelastic tackifier for conventional environment-friendly lubricants, specifically in relation to optimum operating conditions for chainsaws and the like.
To ensure proper function, chainsaw chains and bars must be continuously lubricated to avoid excessive mechanical wear on the interconnected elements of said chain. Virtually all of this lubricant is expelled from the chain during use, flung from the chain in motion or transferred into the affected wood. This categorizes the chain lubricant as a ‘total loss lubricant’, with an estimated 70 million liters of this lubricant being released into the environment per annum. One liter of conventional lubricant oil dispersed into an aquifer can contaminate up to one million liters of potable water. Peripheral environmental hazards stemming from the use of this oil (non-biodegradable benzenes, heavy metals, etc.) may persist after initial exposure, contaminating soil for years if not decades. More immediate concerns of adverse health effects caused by prolonged exposure to vaporized petroleum lubricants have also been noted; workers may suffer increased incidences of metals poisoning and cancer.
In response to the clear environmental hazards posed by the use of conventional petroleum-based lubricants, the demand for environmentally-acceptable products is growing rapidly. One potential alternative is the use of environmentally-neutral water-soluble lubricants produced from vegetable products. Essential features of these environmentally-neutral compounds are non-toxicity and rapid biodegradability, preventing extended contamination of a working area in the event of a spill (or regular loss of lubricant during use). In tandem with the use of more environmentally-friendly compounds for lubrication, battery-powered equipment tools are becoming more popular among operators concerned with noise or atmospheric pollution. It follows, then, that these new tools would require a novel form of lubricant to maximize the efficacy of the electrically-powered tools. Thickening agents added to conventional lubricant compositions, may be extracted or derived from chitin, chitosan, dextrin, cellulose, starch, vegetable gums, hyaluronic acid or derivatives and/or mixtures thereof. Though this additive may decrease viscosity, they do not appreciably increase lubricant retention to the chain. As previously outlined, the high-speed circulation of a chain is liable to shed lubricant at an excessive rate if not properly applied, thereby robbing the chain of essential lubrication.
The present invention comprises a novel additive composition for environmentally-neutral lubricants, specifically targeted towards increasing lubricant retention to the moving components of chainsaws. The ideal function of the present invention would be to increase the adhesive qualities of an aqueous lubricant without compromising the coolant and lubricant roles of such a substance. To wit, the additive compound is a tackifier agent, presented as novel both as an independent composition and in addition to extant lubricants.
All illustrations of the drawings are for the purpose of describing selected versions of the present invention and are not intended to limit the scope of the present invention.

Further, the quantity of the cationic surfactant may range between 0.1 wt. % and 30 wt. % of the aqueous tacky lubricant. However, more specifically, it is preferred that the quantity of the aqueous lubricant additive ranges between 0.001 wt. % and 5 wt. %. Preferably, the lubricant is water-soluble and environment friendly. To that end, the composition of the present invention comprises a quantity of water ranging between 40% wt.-98.099 wt. % of the aqueous lubricant. Thus, as seen in
In the preferred embodiment, the composition of the water-soluble lubricant most directly embodies a unique combination of dried, powdered botanicals observed to be effective in preventing hypoglycemia when delivered orally.

However, it should be noted that the water-soluble or aqueous lubricant may comprise any variety of suitable solvents, and/or one or more ingredients that are known to one of ordinary skill in the art, and may be mixed in different concentrations, as long as the intents of the present invention are not altered.
According to the preferred embodiment, the preferred ranged ratios of the other compositional constituents of the aqueous lubricant are as follows. The quantity of glycerin ranges between 0.1 wt. % and 10 wt. % of the aqueous lubricant, the quantity of propylene glycol ranges between 0.1 wt. % and 75 wt. % of the aqueous lubricant, the quantity of polyalkylene glycol ranging between 0.1 wt. % and 5 wt. % of the aqueous lubricant, the quantity of polyethylene glycol ranges between 0.1 wt. % and 5 wt. % of the aqueous lubricant, the quantity of anti-corrosive agents ranges between 0.5 wt. % and 5 wt. % of the aqueous lubricant, the quantity of anti-wear agents ranges between 0.5 wt. % and 30 wt. % of the aqueous lubricant, and the quantity of preservative agents ranges between 0.01 wt. % and 5 wt. % of the aqueous lubricant.
