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 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.
