摘要: The present invention aims to offer a lubricating composition with excellent heat resistance, mechanical stability, water resistance, corrosion resistance, load resistance and flame resistance. To this end the present invention suggests that from 2 to 68% by weight of tricalcium phosphate relative to the total composition is added to a base oil, which may be a mineral oil and/or a synthetic oil. Surfactants are further added, and the whole is thoroughly mixed and kneaded to give a semi-solid lubricating composition. For the surfactants, non-ionic surfactants are most suitable, and fatty acid esters such as glycerine fatty acid esters, sorbitan fatty acid esters and sucrose fatty acid esters may be used. The amount used is from 0.2 to 18% by weight relative to the total composition.
