Abstract

A method of producing a viscoelastic polyurethane foam coating in which a polyisocyanate is reacted with a polyol to form a prepolymer. The prepolymer is reacted with a polyol having at least one pendant carboxylic acid group to form a prepolymer with a pendant carboxylic acid group. The prepolymer with a pendant carboxylic acid group is neutralized with a tertiary amine and then reacted with water or an organic or inorganic polyamine. An energy absorbing unit in which the coating produced by the above method is provided on a viscoelastic polyurethane foam layer.

Claims (20)

1. ~A method of producing a viscoelastic polyurethane foam coating, the method comprising:

reacting a isocyanate or diisocyanate monomer with a polyol to form a prepolymer, reacting the prepolymer with a polyol, the polyol having at least one pendant carboxylic acid group, to form a prepolymer with a pendant carboxylic acid group, neutralizing the pendant carboxylic acid group with a tertiary amine, and then reacting the result with water or a organic or inorganic polyamine.
2. ~The method as claimed in claim 1, wherein the diisocyanate monomer is selected from a group consisting of toulene diisocyanate, methyl diphenyl dissocyanate, hexamethylene dissocyanate, isophorone diisocyanate, tetramethylxylylene diisocyanate, dicyclohexylmethane 4,4-diisocyanate, xylylene diisocyanate, dimerized diisocyanate, and paraphenylene diisocyanate.
3. ~The method as claimed in claim 1, wherein the isocyanate monomer is a monocarboxylic polyol or a polycarboxylic polyol.
4. ~The method as claimed in claim 1, wherein the polyol is selected from a group consisting of polyether polyol, polyester polyol, polycaprolactone polyol, polybutadiene polyol, polycarbonate polyol, sebaceous polyol, epoxy polyol graft copolymer polyol, acrylic polyol, and polyvinyl chloride polyol.
5. ~The method as claimed in claim 1, wherein the tertiary amine is selected from a group consisting of tirethylamine, diethylamine, aminomethylpropanol and dimethyethylamine.
6. ~The method as claimed in claim 1, wherein the organic or inorganic polyamine is aliphatic, aromatic, cycloaliphatic, or polyoxypropyleneamines.
7. ~A viscoelastic polyurethane foam coating comprising a isocyanate or a diisocyanate monomer crosslinked with a polyol.

14. ~An energy absorbing unit comprising a coating and a foam layer, wherein the coating comprises a isocyanate or a diisocyanate monomer and a polyol.
15. ~The energy absorbing unit as claimed in claim 14, wherein the foam layer is viscoelastic polyurethane foam.
16. ~The energy absorbing unit as claimed in claim 15, wherein the viscoelastic polyurethane foam is slow recovery viscoelastic polyurethane foam, open cell viscoelastic polyurethane foam, closed cell viscoelastic polyurethane foam, or a combination thereof.
17. ~The energy absorbing unit as claimed in claim 14, wherein the diisocyanate monomer is selected from a group consisting of toulene diisocyanate, methyl diphenyl dissocyanate, hexamethylene dissocyanate, isophorone diisocyanate, tetramethylxylylene diisocyanate, dicyclohexylmethane 4,4-diisocyanate, xylylene diisocyanate, dimerized diisocyanate, and paraphenylene diisocyanate.
18. ~The energy absorbing unit as claimed in claim 14, wherein the isocyanate monomer is a monocarboxylic polyol or a polycarboxylic polyol.
19. ~The energy absorbing unit as claimed in claim 14, wherein the polyol is selected from a group consisting of polyether polyol, polyester polyol, polycaprolactone polyol, polybutadiene polyol, polycarbonate polyol, sebaceous polyol, epoxy polyol graft copolymer polyol, acrylic polyol, and polyvinyl chloride polyol.
