ABSTRACT:
A process to manufacture in laboratory and/or industrial scale lubricant greases using hydrophilic or hydrophobic silicon bioxide (fumed silica with a surface area in the range of 120 to 300 m.sup.2 /g), or ground precipitated silicic acid which is mixed and dispersed in an adequate and proportional manner with liquid or solid additives and with either pure paraffinic or naphthenic, heavy or light, refined or regenerated, mineral oils derived from petroleum to obtain mineral lubricant greases, or with treated vegetable oils, such as castor oil and soy oil, or synthetic esters like polyol esters and diesters or glycerine or propylene glycol, in order to obtain synthetic type lubricant greases, or with dimethyl and phenylmethyl polysiloxanes in order to obtain silicon greases. The lubricant greases of this invention may be applied with great advantages in the automotive and food industries, as well as industry in general, due to their special characteristics and properties of lubrication, purity and resistance to high or low temperatures, to water and to some solvents.
