| 发明名称 | Methods for producing composite elements based on foams based on isocyanate | ||
| 摘要 | 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. | ||

| 主权项 | 1. A process for the production of composites, comprising at least one outer layer and of an isocyanate-based rigid foam, where the outer layer is moved continuously and a liquid starting material for the isocyanate-based rigid foam is applied to the outer layer, which comprises achieving an application of the liquid starting material for the isocyanate-based rigid foam through at least two fixed tubes, each of which has openings and which has been placed, with respect to the outer layer, so as to be parallel to the plane of the outer layer, wherein the ratio of the lengths of the openings between the site of the feed of the starting material for the isocyanate-based rigid foam and the end of each tube is from 1.1 to 20. | ||
