POLYURETHANE COMPOSITION FOR ARTICLES WITH ANTIFRICTION PROPERTY Russian patent published in 2006 - IPC C08L75/08 C08G18/61 C08J5/16

Abstract RU 2287539 C1

FIELD: polymers.

SUBSTANCE: invention relates to polyurethane compositions designated for making abrasion-resistant articles possessing antifriction properties. The composition comprises polyoxytetramethylene glycol with molecular mass 1000 Da, 2,4-toluylenediisocyanate, liquid hardening agent as solution of 3,3'-dichloro-4,4'-diaminodiphenylmethane in polyoxytetramethylene glycol with molecular mass 1000 Da and low-molecular silicon rubber SKTN (7-10%). Invention provides preparing elastoplastics possessing the low friction coefficient (0.22-0.24) and high physical-mechanical indices.

EFFECT: improved and valuable properties of composition.
