Abstract

Se divulga un metodo para producir una estructura compuesta de poliurea-poliuretano el cual esta substancialmente libre de emision de compuestos organicos volatiles. La estructura compuesta producido segun el metodo del presente invento tiene un modulo de flexion de por lo menos 66,506 N/m2. La estructura compuesta incluye primeras y segundas capas. Un substrato de molde es proporcionado y un componente de poliisocianato de primera capa y un componente de resina de primera capa son reaccionados y rociados sobre el substrato de molde para formar la primera capa. El componente de poliisocianato de primera capa incluye un poliisocianato alifatico, y el componente de resina de primera capa incluye una poliamina por consiguiente formando una superficie mostrario de poliurea con una dureza Shore D de por lo menos 65. Despues de aplicar la primera capa, un componente de poliisocianato de segunda capa y un componente de resina de segunda capa son reaccionados y rociados detras de la primera capa para formar la segunda capa de la estructura compuesta. El componente de resina de segunda capa incluye, de manera mas especifica, un poliol con una funcionalidad teorica de por lo menos tres. Las primeras y segundas capas de la estructura compuesta estan substancialmente libres de compuestos organicos volatiles (VOCs por su sigla en ingles).
