METHOD OF PREPARING GREASES
Document Type and Number:
Japanese Patent JP2014208851
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method for preparing a grease composition, which comprises mixing grease components under high pressure and high flow rate impingement.SOLUTION: In one embodiment, a first mixture of an amine in a lubricating base oil is mixed with an isocyanate in a lubricating base oil under high pressure and high flow impingement. In another embodiment, the mixing and reaction occurs in a reaction injection molding device. The size of an orifice through which each of the mixtures is introduced into a reaction/mixing zone is less than 0.030 inch (0.0762 centimeter) in diameter. The resulting grease composition is an extremely low noise grease, being virtually clear of any urea thickener particles, and/or can exhibit good high temperature resistance and mechanical stability.
