The present invention relates to a process for producing composite profiles comprising at least two metal shells which are joined by struts comprising a thermoplastic material and a core comprising rigid polyurethane foam, which comprises introduction of the starting components of the rigid polyurethane foam into a hollow space formed by the metal shells, with the rigid polyurethane foam being formed, and subsequent application of a surface coating to the outer surface of the composite profile by means of a powder coating or baking enamel, where the rigid polyurethane foam is obtained by reaction of the following components:

Process for producing composite profiles

The invention relates to a process for the production of composites, composed of at least one outer layer b) and of an isocyanate-based rigid foam a), where the outer layer b) is moved continuously and the starting material for the isocyanate-based rigid foam a) is applied to the outer layer b), which comprises achieving the application of the liquid starting material for the isocyanate-based rigid foam a) by means of at least one fixed tube c) which has openings f) and which has been placed, with respect to the outer layer b), so as to be parallel to the plane of the outer layer and at right angles to the direction of movement.

Methods for producing composite elements based on foams based on isocyanate

An apparatus for application of liquids to a continuously conveyed outer layer having a rotating plate which is horizontal and parallel to the outer layer or with a deviation of up to 15&#xb0; from horizontal, wherein a liquid applied to the rotating plate is ejected centrifugally from the rotating plate via rotation and then, via gravity, passed onto the outer layer below the rotating plate, is provided.

Method for the production of composite elements based on isocyanate-based foams

The invention relates to a process for production of composite elements composed of at least one outer layer a) and of an rigid isocyanate-based foam b), where between the outer layer a) and the rigid isocyanate-based foam b) an adhesion promoter c) has been applied, and where the outer layer a) is continuously moved and the adhesion promoter c) and the starting material for the rigid isocyanate-based foam b) are applied successively to the outer layer, which comprises applying the adhesion promoter c) by means of a rotating plate which has been installed horizontally or with a deviation of up to 15&#xb0; from horizontal, preferably parallel to the outer layer.
