| description | La presente invención se refiere a un método para preparar un bloque de espuma de poliuretano/poliisocianurato fibroso, en el que la expansión de la espuma está restringida por las paredes de un laminador de doble banda que forma un túnel, siendo el bloque de espuma de poliuretano/poliisocianurato fibroso compuesta por celdas que almacenan un gas, ventajosamente de baja conductividad térmica, y de densidad inferior a 50 kg.m-3 con una relación de fibras Tf que constituye al menos el 4% en masa del bloque de espuma fibrosa, en el que el tiempo de impregnación de las fibras ti es menor que el tiempo de crema tc de la espuma de poliuretano/poliisocianurato.

The present invention relates to a preparation of a block of fiber-reinforced polyurethane/polyisocyanurate foam in which the expansion of the foam is constrained by the walls of a double belt laminator forming a tunnel, the block of fiber-reinforced polyurethane/polyisocyanurate foam being composed of cells storing a gas, advantageously having low thermal conductivity, and exhibiting a density of less than 50 kg·m−3 with a content of fibers Cf representing at least 4% by weight of the block of fiber-reinforced foam, in which the impregnation time of the fibers ti is less than the cream time tc of the polyurethane/polyisocyanurate foam. |
