Composite materials based on rubbers, elastomers, and their recycled

A material based on rubbers, elastomers, and/or recycling thereof consisting of:

• a) at least one rubber based on polybutadienes, butadiene-styrene, poly-acrylonitrile butadiene, neoprene, butyl rubbers, poly-isobutylenes, poly-isobutylene isoprene, chloroprene;
• or ethylene- propylene, the at least one rubber having a particle size between 9.51 mm to 0.075 mm;
• b) at least one elastomer derivative of the rubbers of a), wherein the at least one rubber derivate is partially or totally cross-linked and having a particle size between 9.51 mm to 0.075 mm;
• and
• c) at least one recycled rubber, the recycled rubber is partially or totally cross-linked by different chemical reactions generating a vulcanization state;
• having homogeneous sizes with a particle size between 9.51 to 0.075 mm;
• d) a polyurethane binder including a soft segment and a hard segment, the soft segment is in the amount of 10 to 90% by weight, based on a total weight of the polyurethane;
• the hard segment includes diisocyanates selected from the group consisting of 4,4′-diisocyanate diphenylmethane (“MDI”), p-phenylene diisocyanate, 1,3-bis(isocyanatomethyl)- cyclohexane, 1,4-diisocyanate-cyclohexane, hexamethylene diisocyanate, 1,5-naphthalene diisocyanate, 3,3′-dimethyl-4,4′-biphenyl diisocyanate, 4,4′-diisocyanate-dicyclohexylmethane, and 2, 4-toluene diisocyanate;
• the soft segment polyester diols obtained by the reaction of:
• diols selected from the group consisting of 1,4-butanediol, hydroquinone bis(2-hidroxyethyl) ether, ethylene glycol, diethylene glycol, triethylene glycol, propylene glycol, dipropylene glycol, 2-methyl-2-ethyl-1,3-propanodiol, 2-etil-1,3-hexanediol, 1,5-pentanediol, thiodiglycol, 1,3-propanediol, 1,1,3-butanediol, 2,3-Butanediol, 1, neopentylalcohol glycol, 2-dimethyl-1, 2-ciclopentanodiol, 1, 6-hexanediol, 1, 1,2-cyclohexenodiol, 2-dimethyl-1,2-cyclohexanediol, glycerol, trimethylol propane, trimethylol ethane, 1,2,4-butanediol, 1,2,6, pentaerythritol, dipentaerythritol, tripentaeritritol, anhidroanheptitol, mannitol, sorbitol, methyl-glucoside, and
