METHOD OF PREPARING POLYMER SPORTS COATING Russian patent published in 2010 - IPC C09D175/04 E01C13/06 

Abstract RU 2391373 C2

FIELD: chemistry.

SUBSTANCE: invention relates to polymer construction compositions and can be used for making sports coatings. The coating is formed by depositing a composition onto a hard base, where the composition contains an isocyanate prepolymer, a mixture of chalk and caustic lime in ratio of 5:1, a mixture of chlorinated paraffin wax, low-molecular polyethylene and calcium oxide in ratio of 1:2:0.5, a catalyst, low-molecular tri-functional alcohol, chlorinated paraffin wax, plasticiser and holding for 20-24 hours. A second layer is deposited, based on a polymer composition which contains oligodienediol with molecular weight of 2000-5000 and 0.7-1.7% content of hydroxyl groups, a plasticiser, mineral filler, a mixture of chlorinated paraffin wax, low-molecular tri-functional alcohol, polyisocyanate, catalyst, 2,4,6-tri-tertbutylphenol, ethyl silicate and kept for 20-24 hours. A third layer of polymer composition is deposited, which contains a polysulphide oligomer, a plasticiser, zinc oxide, rubber crumbs with particle size of 3 mm and 1 mm in ratio of 3:1, vulcanising paste No.9, diphenylguanidine, oligodienediol with molecular weight of 2000-5000 and 0.7-1.7% content of hydroxyl groups, low-molecular tri-functional alcohol, polyisocyanate, catalyst and subsequently holding for 20-24 hours.

EFFECT: improved dynamic and elastic-hysteresis properties, hydrolytic and thermal oxidative stability of the coating.
