Abstract: A continuous process forms a unitary mat on a line having at least two conveyors spaced from each other. The process includes combining the isocyanate, an isocyanate catalyst, and a plurality of lignocellulosic particles to form a mixture and a self-polymerization product of the isocyanate in-situ in the mixture. The process also includes forming the unitary mat from the mixture on a first conveyer and transferring the unitary mat from the first conveyor to a second conveyor across a predetermined distance while maintaining structural integrity of the unitary mat. The lignocellulosic particles have a moisture content of 0.5 to 30 weight percent of water. Moreover, the continuous process is free of a step of adding water to the isocyanate, the isocyanate catalyst, the lignocellulosic particles, and/or the unitary mat.

Abstract: Un método para formar un componente polimérico con funcionalidad isocianato incluye formar una primera mezcla mezclando un artículo de poliuretano reciclado y un primer componente isocianato que tiene grupos con funcionalidad isocianato. La primera mezcla se calienta a una temperatura suficiente para transformar el artículo de poliuretano reciclado de una forma sólida a una forma líquida y hacer reaccionar el componente de poliuretano reciclado líquido con el primer componente isocianato para formar un componente polimérico con funcionalidad isocianato que tiene un contenido de grupo funcional isocianato. contenido de grupos funcionales isocianato mayor que cero y menor que el del primer componente isocianato. El componente polimérico con funcionalidad isocianato formado se puede usar entonces para formar un artículo de poliuretano o un artículo de espuma de poliuretano que es el producto de reacción del componente polimérico con funcionalidad isocianato formado, un segundo componente isocianato y un componente reactivo con anisocianato que tiene grupos funcionales hidroxilo.

Abstract: A method of forming an isocyanate-functional polymer component includes forming a first mixture by mixing a recycled polyurethane article and a first isocyanate component having isocyanate-functional groups. The first mixture is heated to a temperature sufficient to transform the recycled polyurethane article from a solid form to a liquid form and react the liquid recycled polyurethane component with the first isocyanate component to form an isocyanate-functional polymer component having an isocyanate-functional group content greater than zero and less than isocyanate-functional group content of the first isocyanate component. The formed isocyanate-functional polymer component may then be used for forming a polyurethane article or polyurethane foam article that is the reaction product of the formed isocyanate-functional polymer component, a second isocyanate component and anisocyanate-reactive component having hydroxyl-functional groups.
