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, an applicator having an A-side intake, a B-side intake, and at least one nozzle head, an A-side comprising an isocyanate, and a B-side comprising an esterified polyol and a catalyst wherein the esterified polyoi comprises the reaction product of a first polyol and a blown vegetable oil and the first polyol comprises the reaction product of a first multifunctional compound and a second multifunctional compound;
directing the applicator toward the substrate; and
passing the A-side through the A-side intake of the applicator and the B-side through the B-side intake of the applicator such that the A-side and B-side react and contact the carpet substrate.
2. The method of manufacturing a carpet material of claim 1 further comprising the step of moving the applicator to substantially evenly coat the carpet substrate.
3. The method of manufacturing a carpet material of claim 2 , wherein the movement of the applicator is controlled by a computer.
4. The method of manufacturing a carpet material of claim 3 , wherein the applicator moves along an X-axis and a Y-axis.
5. The method of manufacturing a carpet material of claim 1 , wherein the first multifunctional compound comprises a multifunctional alcohol and the second multifunctional compound comprises a saccharide compound.
6. The method of manufacturing a carpet material of claim 1 , wherein the B-side further comprises a blowing agent.
7. The method of manufacturing a carpet material of claim 6 , 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.
8. The method of manufacturing a carpet material of claim 7 , wherein the blown vegetable oil comprises a blown soy oil.
9. The method of manufacturing a carpet material of claim 8 , wherein the B-side further comprises a cross-linker.
10. The method of manufacturing a carpet material of claim 6 , wherein the B-side further comprises a cross-linker.
11. The method of manufacturing a carpet material of claim 1 , wherein the B-side further comprises a polyol at least partially derived from petroleum.
