Abstract:
The invention relates to a method for producing composite bodies consisting of at least one covering layer a) and a rigid foamed material based on isocyanate b), the covering layer a) being continuously moved and the starting material for the rigid foamed material based on isocyanate b) being applied to the covering layer. The invention is characterised in that the application of the liquid starting material for the rigid foamed material based on isocyanate b) is carried out by means of a fixed tube provided with boreholes and oriented towards the covering layer in such a way that it is parallel and at a right angle to the direction of movement.
Abstract:
Método para producir elementos compuestos, que se componen al menos de una capa de cobertura a) y una espuma rígida a base de isocianato b), en la cual la capa de cobertura a) se mueve continuamente y el material de inicio para la espuma rígida a base de isocianato b) se aplica sobre la capa de cobertura, en cuyo caso la descarga del material de inicio líquido para la espuma rígida a base de isocianato b) se efectúa por medio de un tubo provisto de orificios, parado fijo, dispuesto en paralelo y en ángulo recto a la dirección de movimiento de la capa de cobertura a), caracterizado porque el material de inicio para la espuma rígida a base de isocianato b) se abastece en el centro del tubo provisto de orificios y porque el diámetro del tubo provisto de orificios se disminuye desde el centro hacia los bordes del tubo.
Abstract:
The invention relates to a method for producing composite bodies consisting of at least one covering layer (4) and a rigid foamed material (5) based on isocyanate, the covering layer (4) being continuously moved and the starting material for the rigid foamed material (5) based on isocyanate being applied to the covering layer (4). The invention is characterised in that the application of the liquid starting material for the rigid foamed material (5) based on isocyanate is carried out by means of a fixed tube (3) provided with boreholes and oriented towards the covering layer (4) in such a way that it is parallel and at a right angle to the direction of movement.
Abstract:
The invention relates to a process for producing composite bodies comprising at least one covering layer a) and a rigid foam based on isocyanate b), in which the covering layer a) is moved continuously and the starting material for the rigid foam based on isocyanate b) is applied to the covering layer, wherein the application of the liquid starting material for the rigid foam based on isocyanate b) is effected by means of a fixed tube which is provided with orifices and is arranged parallel to the covering layer a) and at right angles to the direction of movement of the covering layer a).
Abstract:
The present invention relates to a method for producing a composite element, at least comprising steps of providing a cover layer having an uncoated surface and a coated surface, which is at least partially coated with a composition (B) comprising at least one inorganic material, treating the uncoated surface of the cover layer, and applying a composition (Z2), which is suitable for producing a polyurethane and/or polyisocyanurate foam, to the treated surface of the cover layer. The present invention further relates to a composite element obtainable or obtained according to a method according to the invention and to the use of a composite element obtainable or obtained according to a method according to the invention or of a composite element according to the invention as an insulating material or in façade construction.
