COATING FOR SURFACE OF RUBBER-POLYOLEFINE COMPOSITION Russian patent published in 2010 - IPC C09D123/02 C09D125/04 C09D107/00 C09D109/00 C09D127/06 B29B9/06 B29C43/24 E04F15/10 

FIELD: construction industry.

SUBSTANCE: invention refers to floor covering of rubber-polyolefine composition and method of obtaining thereof. Covering for surface includes 5 to 50 wt/wt % of thermoplastic material chosen from the group including polyethylene of extra-high molar weight, ion metre or copolymer of ethylene with methylmethacrylate, copolymer of ethylene with acrylamide, polystyrene, copolymers of ethylene with butyl acrylate, ethylene with methyl acrylate, ethylene with vinyl acetate, ethylene with octane, polyvinyl chloride, polyethylene, polypropylene, polybutene, and their mixture, from 5 to 50 wt/wt % of elastomeric material chosen from the group including styrene-butadiene rubber, nitrile-butadiene rubber, natural rubber, isoprene rubber, ethylene-propylene rubber and their mixture, from 5 to 20 wt/wt % of resin with high content of styrene, from 25 to 70 wt/wt % of filler and from 1 to 10 wt/wt % of vulcanising system. Method is implemented by mixing thermoplastic material, elastomeric material, resin with high content of styrene, filler, vulcanising system, calendering of mixture thus obtaining at least two calendered sheets, granulation of these sheets thus obtaining granules, mixing of the above granules and obtaining marble-like coating for surface by means of these granules and vulcanisation of elastomeric material.

EFFECT: obtaining the coating with increased resistance to tear and resistance to formation of spots.
