Abstract
Surface coating composition, method and apparatus for coating a surface. The surface coating composition comprises a recycled rubber product, one or more binding agent and optionally one or more additional agent.
Claims14
A surface coating composition comprising:
- crumbs of size 10-20 mesh and buffings from a recycled rubber product,
- a binding agent consisting of a mixture of:
- an epoxy-based binding agent and
- a polyurethane-based binding agent, and
- up to 3% by weight of the composition of fibers selected from polyester, nylon, Kevlar and their mixture thereof.
2 more elements
A surface coating composition comprising:
- 10% to 90% by weight of 10-20 crumb and buffings from a reclaimed tire processing product obtained from whole tire processing without chemical treatment;
- 90% to 10% by weight of a polyurethane-based binding agent produced from a reaction between a polyisocyanate that is diphenylmethane diisocynate (MDI), tolulene diisocynate (TDI), naphthalene diisocynate (NDI) m- and p-phenylene diisocyanate, p,p′-diphenyl diisocyanate tetra-, penta-, hexa-, hepta-, and octa-methylene diisocyanate, cyclohexylene diisocyanate, or polymethylene polyphenyl isocyanates, and mixtures thereof;
- and a polyol that is a polyethylene glycol, a polyester polyol, glycerol or ethylene glycol, in the presence of catalysts;
- up to 3% by weight of the composition of fibers selected from polyester, nylon, Kevlar and their mixture thereof;
- a viscosity reducing agent;
- and
- a fire retardant;
- wherein 80% of the total crumb weight is crumb rubber particles in the 1-3 mm range and the size of said buffings is above 90 mesh.
5 more elements
A surface coating composition comprising:
- crumbs of size 10-20 mesh and buffings obtained from a recycled rubber product;
- a binding agent consisting of
- a polyurethane-based binding agent produced from a reaction between an aromatic or aliphatic type polyisocyanate and a polyol in the presence of catalysts, and
- up to 3% by weight of fibers selected from polyester, nylon, Kevlar and their mixture thereof.
