COMPOSITE MATERIAL FOR MANUFACTURE OF THE TRIBOENGINEERING COATINGS Russian patent published in 2007 - IPC C09D177/00 C10M161/00 

FIELD: chemical industry; mechanical engineering; production of the polymeric composite material.

SUBSTANCE: the invention is pertaining to the field of the polymeric materials technology, in particular, to the triboengineering material science and may be used in mechanical engineering for manufacture of the antifrictional coatings of the details of the friction units operating mainly without supply of the external greasing. The invention is pertaining to the composite material for the tribotechnical coatings on the basis of the polyamide 6 containing the polymeric modifier and the dry greasing. As the polymeric modifier the composite material contains the mixture of the powders of polyamide 11 and the polytetrafluoroethylene at the ratio of 1:1÷5:1 of the identical dispersity with the polyamide 6 powder, and as the dry greasing - the laminated silicate-containing mineral at the following ratio of the components (in mass %): the mixture of the powders - 2.0-60.0, polyamide - 11 and polytetrafluoroethylene - at the ratio of 1:1÷5:1, the laminated silicate-containing mineral - 0.1 ÷ 1.0, polyamide 6 - the rest.

EFFECT: the invention ensures manufacture of the antifrictional coatings for the details of the friction units operating mainly without supply of the external greasing.
