Vegetable oil-based coating and method for application
View Patent ↗A vegetable oil-based coating and a method for applying the coating to a substrate where the coating includes the reaction product of a transesterified vegetable oil-based polyol, a catalyst, and an isocyanate; the reaction product of a vegetable oil based polyol, a cross-linker, a catalyst, and an isocyanate where the vegetable-oil based polyol may optionally be oxylated and/or neutralized.
1. A method of coating a substrate with a material comprising:
providing a substrate, an applicator comprising an A-side intake, an A-side outlet, a B-side intake, a B-side outlet, and a nozzle head and an A-side reactant comprising an isocyanate and a B-side reactant wherein the B-side reactant comprises a blown vegetable oil, a cross-linking agent comprised of a multifunctional alcohol, and a catalyst; and
passing the A-side reactant through the A-side intake of the applicator and the B-side reactant through the B-side intake of the applicator such that the A-side and the B-side reactants pass through the A-side and B-side outlets and contact the substrate.
2. The method of claim 1 , wherein the B-side further includes a blowing agent.
3. The method of claim 1 , wherein the blown vegetable oil comprises a blown vegetable chosen from the group consisting of a blown soy oil, a blown rapeseed oil, a blown cottonseed oil, and a blown palm oil.
4. The method of claim 1 , wherein the blown vegetable oil comprises a blown soy oil.
5. The method of claim 1 , wherein the catalyst comprises a tertiary amine.
6. The method of claim 1 , wherein the multifunctional alcohol is present in a ratio to the vegetable oil such that there are at least 0.7 moles of hydroxyl (OH) groups per mole of vegetable oil.
7. The method of claim 1 , wherein the isocyanate comprises an isocyanate chosen from the group consisting of 2,4 toluene diisocyanate, 4,4′ diphenylmethane diisocyanate, and 2,4 diphenylmethane diisocyanate.
8. The method of claim 1 , wherein the B-side further comprises a surfactant.
9. The method of claim 1 , wherein the isocyanate comprises a mixture of at least two isocyanates.
10. The method of claim 9 , wherein the isocyanate comprises a mixture of at least two isocyanates selected from the group consisting of 2,4 toluene diisocyanate, 4,4′ diphenylmethane diisocyanate, and 2,4 diphenylmethane diisocyanate.
11. The method of claim 2 , wherein the blowing agent comprises a blowing agent chosen from the group consisting of water, acetone, methyl isobutyl ketone, methylene chloride, a hydrochloroflurocarbon, and a hydroflurocarbon.
12. The method of claim 1 , wherein the multifunctional alcohol comprises a multifunctional alcohol selected from the group consisting of ethylene glycol, 1,4, butanediol, and dipropylene glycol.
13. The method of claim 1 , wherein the multifunctional alcohol comprises a combination of ethylene glycol and 1,4 butanediol.
14. The method of claim 1 , wherein the B-side further comprises a polyol at least partially derived from petroleum.
15. The method of claim 14 , wherein the polyol at least partially derived from petroleum comprises a polyurea polyol.
16. The method of claim wherein the substrate comprises a carpeting material.
17. The method of claim 1 , wherein the blown vegetable oil is reacted with an alkyl oxide.
18. The method of claim 17 , wherein the alkyl oxide comprises an alkyl oxide chosen from the group consisting of propylene oxide, butylene oxide, and ethylene oxide.
19. A method of coating a substrate with a material comprising:
providing a substrate; a spray applicator comprising an A-side inlet, a B-side inlet, and a sprayer head comprising an A-side outlet and a B-side outlet; an A-side reactant comprising an isocyanate; and a B-side reactant comprising a blown vegetable oil, a polyol at least partially derived from petroleum, a cross-linker, and a catalyst;
directing the spray applicator toward the substrate;
passing the A-side reactant through the A-side intake of the applicator and the B-side reactant through the B-side intake of the applicator; and
passing the A-side reactant and the B-side reactant through the sprayer head such that the A-side and B-side reactants react and contact the substrate material.
20. The method of claim 19 , wherein the polyol at least partially derived from petroleum comprises a polyol at least partially derived from petroleum chosen from the group consisting of a polyether polyol, a polyester polyol, and a polyurea polyol.
21. The material produced according to claim 19 .
22. The method of claim 14 , wherein the polyol at least partially derived from petroleum comprises a polyol at least partially derived from petroleum chosen from the group consisting of a polyether polyol, a polyester polyol, and a polyurea polyol.
