Vegetable oil-based coating and method for application
View Patent ↗A method for manufacturing a carpet material that typically includes applying a coating to a substrate where the coating includes the reaction product of a B-side that includes an esterified vegetable oil-based polyol and a catalyst and an A-side that includes an isocyanate and the reaction product of a B-side that includes a vegetable oil-based polyol and a catalyst and an A-side that includes an isocyanate. The polyols may optionally be blown, oxylated, and/or neutralized.
1. A method of manufacturing a carpet material comprising:
providing a carpet substrate; and
engaging a material and the carpet substrate wherein the material comprises the reaction product of an A-side comprising an isocyanate and a B-side comprising a blown soy oil, a polyol at least partially derived from petroleum, a cross-linker, and a catalyst.
2. The method of manufacturing a carpet material of claim 1 , wherein the cross-linker comprises hydroxyl groups and the molar ratio of the hydroxyl groups of the cross-linker to hydroxyl groups of the blown soy oil is at least 0.7:1.
3. The method of manufacturing a carpet material of claim 2 , wherein the B-side further comprises a blowing agent.
4. The method of manufacturing a carpet material of claim 3 , wherein the blowing agent comprises at least one blowing agent chosen from the group consisting of a hydrochlorofluorocarbon, a hydrofluorocarbon, a hydrocarbon, water, and methylene chloride.
5. The method of manufacturing a carpet material of claim 1 , wherein the B-side further comprises a blowing agent.
6. The method of manufacturing a carpet material of claim 5 , wherein the B-side further comprises a surfactant.
7. The method of manufacturing a carpet material of claim 1 , wherein the B-side further comprises a surfactant.
8. The method of manufacturing a carpet material of claim 1 , wherein the cross-linker comprises a multifunctional alcohol and the B-side further comprises a polyol derived from petroleum.
9. The method of manufacturing a carpet material of claim 8 , wherein the B-side further comprises a blowing agent.
10. The method of manufacturing a carpet material of claim 8 , wherein the polyol derived from petroleum has a molecular weight of 4,000.
11. The method of claim 10 , wherein the B-side comprises two different non-acid blocked catalysts.
12. The method of claim 11 , wherein the B-side comprises a non-acid blocked dibutyltin dilaurate catalyst and a non-acid blocked alkyltin mercaptide catalyst.
13. The method of manufacturing a carpet material of claim 8 , wherein the polyol derived from petroleum is two functional.
14. The method of claim 8 , wherein the B-side comprises two different non-acid blocked catalysts.
15. The method of claim 14 , wherein the B-side comprises a non-acid blocked dibutyltin dilaurate catalyst and a non-acid blocked alkyltin mercaptide catalyst.
