COMPOSITION FOR SELF-HARDENING ANTIFRICTION COVER Russian patent published in 2006 - IPC C08J5/16 C08L33/08 C08K3/30 C08K3/02 C08K7/18 

FIELD: antifriction materials.

SUBSTANCE: invention relates to antifriction self-hardening covers based on polymeric binding agent. Proposed composition comprises the following components, wt.-%: molybdenum disulfide, 10.0-18.0; crystalline iodine, 0.2-0.6 and polyacryl lacquer. For improving antifriction properties ultradispersed β-sialone in the amount 0.2-0.5 wt.-% can be added to composition additionally. Composition is prepared by mechanical mixing components. Ready composition is applied on working surface of unit friction article by spraying, immersion method or by a brush. Prepared cover is dried at temperature 20 ± 5°C for 0.5-2 h. Prepared covers are especially effective for applying on articles that can't be heated or in case of difficult heating. Proposed composition is used in machine engineering for applying on friction unit articles working without lubrication. Invention provides enhancing antifriction properties of composition, adhesion to steel and exclusion the necessity of temperature effect.

EFFECT: improved and valuable technical properties of composition.
