Gelatinous Triblock Copolymer Elastomer Particles in Polyurethane Flexible Foams

Номер: US20130316164A1
Автор: Crawford Mark L., Peterson Bruce W.
Принадлежит: Peterson Chemical Technology, Inc.

Combinations of gelatinous elastomer and polyurethane foam may be made by introducing a plasticized triblock copolymer resin and/or a diblock copolymer resin at least partially cured into gel particles into a mixture of polyurethane foam forming components including a polyol and an isocyanate. The plasticized copolymer resin is polymerized to form a cured gelatinous elastomer or gel, which is then reduced in size, for instance to give an average particle size of 10 millimeters or less. Polymerizing the polyol and the isocyanate forms polyurethane foam. The polyurethane reaction is exothermic and can generate sufficient temperature to at least partially melt the styrene-portion of the triblock copolymer resin thereby extending the crosslinking and in some cases integrating the triblock copolymer within the polyurethane polymer matrix. The gel component has higher heat capacity than polyurethane foam and thus has good thermal conductivity and acts as a heat sink. 2.

The present invention pertains to foam cushion backings. More particularly, the present invention pertains to foam cushion backings suitable for use in carpets and carpet tile products. The present invention further pertains to foam cushion-backed carpet and carpet tile products. The present invention further pertains to methods of making such foam cushion backings and carpet and carpet tiles as described herein. 1. A foam cushion backing comprising: 'i) one or more of a homogenously branched ethylene polymer (HBEP) or a substantially linear ethylene polymer (SLEP),', 'a) a foamable polymer composition comprisingwherein a foam cushion backing is prepared from the foamable polymer composition,{'sup': '3', 'wherein the foam cushion backing is substantially uncrosslinked, has a thickness of greater than 0.075 inches, has a uniform density in the range of from 10 to 30 lbs/ft, and'}wherein the foam cushion backing is suitable for use in carpet or carpet tiles.2. (canceled)3. The foam cushion backing of claim 1 , comprising the SLEP.4. The foam cushion backing of having a thickness of from about 0.100 to about 0.225 inches.5. The foam cushion backing of claim 1 , wherein the foamable polymer composition further comprises ii) an adhesive polymer component comprising an adhesive material claim 1 , and wherein the adhesive material comprises a functionalized polymer or copolymer.6. The foam cushion backing of claim 5 , wherein the foamable polymer composition comprises from about greater than 0 to about 10% of the functionalized polymer or copolymer claim 5 , as measured by total weight of the foamable polymer composition.7. The foam cushion backing of claim 5 , wherein the functionalized polymer or copolymer material comprises maleic anhydride grafted to an ethylene polymer.8. The foam cushion backing of claim 1 , wherein the foamable polymer composition further comprises iii) a filler component.9. (canceled)10. (canceled)11. (canceled)12. (canceled)13. (canceled)14.
