Definitions
- This invention relates to a polymer-thickened grease composition more particularly it relates to a polyolefinthickened grease composition.
- the grease compositions of the present invention preferably have a penetration above 300, more preferably of 310-500.
- the penetration of the greases can be measured by Test Method ASTM 217-68.
- Greases were prepared from two different lubricating base oilsby heating halfthetotal quantity ofoil and the polyethylene to C. The ataetic polypropylene was slowly added whilst heating to C. mins.
- the batch was held at 150C for 1 hour, to allow the t polymers to swell and partially dissolve.
- the batch was heated to C and held at this temperature for at least 30 mins to give a complete solution of the polymers.
- the rest of the lubricating oil was added and the batch cooled as quickly as possible to form a grease.
- the grease was circulated through a homogeniser at 80C to give a smooth grease.
- Tables I and 2 give information on the materials used in the forming of greases in Table 3.
- Table 4 shows'the effect of Melt Index on Grease Structure.
- smooth means a grease having a smooth consistency and is substantially homogeneous, grainy meanshaving the appearance of grains or particles in the grease, and rubbery means a more cohesive and spongy or elastic structure than the well known buttery structure of most lubricating greases.
- rubbery means a more cohesive and spongy or elastic structure than the well known buttery structure of most lubricating greases.
- the molecular weight of the polyethylene is from 20,000 to 500,000 weight average, more preferably from 50,000 to 250,000.
- the total weight of polymer in the grease is preferal-20f/r, more preferably 3-157! based on the total weight of the composition.
- a grease composition as claimed in claim 1 in l A grease composition which consists essentially of a lubricating base oil thickened to a grease consistency with from 1 to 20% weight of a polymer mixture, said polymer mixture consisting of an atactic polypropylene of melt index above 50 and a molecular weight below 100,000, and a polyethylene of density above 0.94 grm- /cc and molecular weight of 20,000 to 500,000, the weight ratio of said atactic polypropylene to polyethylene being from 1:1 to 10:1.
- weight ratio of atactic polypropylene to polyethylene is from 2:1 to 5:1.
- a grease composition as claimed in claim 1 which has a penetration above 300.
- a grease composition as claimed in claim 1 which has a penetration of 310 to 500.
