RUBBER COATING Russian patent published in 2006 - IPC C09D175/14 C08L15/00 

FIELD: rubber materials.

SUBSTANCE: invention relates to rubber coatings used mainly for sporting platforms, floorings, roofing and insulating coverings. The coating composition comprises the following components, mas. p. p.: hydroxyl-containing copolymer of isoprene and butadiene with the ratio of monomers = 20:80, molecular mass 3000-3500 Da, the content of hydroxyl groups is 0.7-1.1 wt.-%, 100; polyisocyanate, 10-36; catalyst for urethane formation, 0.001-0.3. Coating can comprise additionally a water-absorbing agent, up to 20; a filling agent, up to 250; plasticizer agent and/or solvent, up to 100; low-molecular alcohol or aminophenol component, up to 8; an alkynophenol antiager, up to 2; pigment, up to 10, and components improving rheological properties or organosiloxane modifying agents, up to 5. Proposed composition provides enhancing abrasion resistance and coating structure.

EFFECT: improved and valuable properties of coatings.
