REFRACTORY POLYMER COMPOSITION Russian patent published in 2018 - IPC C08L9/00 C08L9/02 C08L9/06 C08L23/08 C08J3/24 C09D5/18 C09K21/06 C08J9/00 D06M15/693 F16F7/12 

FIELD: chemistry.

SUBSTANCE: invention relates to the refractory polymer composition suitable for use when applying the coating on the treated articles containing thermoplastic polymer containing vinyl acetate, and an unsaturated elastomer containing double bonds as polymeric components, where the polymer components are present in the form of a homogeneous polymer blend, and where a composite matrix is formed, vulcanized only with the use of sulfur or a crosslinking system containing sulfur, where the sulfur crosslinking system is distributed throughout the matrix and fully penetrates into the matrix, and at least one flame retardant or a combination of flame retardants. The invention further relates to articles obtained from such a composition and to composite elements coated with the composition as well as to the method for their preparation.

EFFECT: producing compositions for protecting a dynamically tense component with a coating of this composition, so that the aggregate component is sufficiently refractory, in particular, complies with the standard for fire safety CEN TS 45545-2 without rendering noticeable adverse effects by the specified coating on the dynamic properties of the composite element during its service life.
