  • Method for the production of composite elements based on isocyanate-based foams
    Patent number: 8578876
    Abstract: 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° 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.
    Type: Grant
    Filed: September 20, 2010
    Date of Patent: November 12, 2013
    Assignee: BASF Aktiengesellschaft
    Inventors: Erwin Calgua, Bernd Schaper, Lars Schoen, Peter von Malotki, Pit Lehmann, Michael Thater
  • Method for the production of composite elements based on mineral or organic thermal insulation materials with the aid of an adhesive
    Patent number: 8007611
    Abstract: The invention provides a method for the production of composite elements composed of at least one outer layer a) and a thermal insulation material b), where between the outer layer a) and the thermal insulation material b) an adhesive c) has been applied, the outer layer a) being moved continuously, the thermal insulation material b) being applied to the outer layer a) and, if appropriate, a further outer layer a) being applied to the thermal insulation material b), and the adhesive c) being applied to the thermal insulation material b) or to the outer layer a), which comprises applying the adhesive c) by means of a rotating flat body which is mounted horizontally or with a slight deviation from the horizontal, of up to 15°, preferably parallel to the outer layer a) or to the thermal insulation material b).

  • Method for the production of composite elements based on isocyanate-based foams
    Patent number: 7871489
    Abstract: 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° from horizontal, preferably parallel to the outer layer.
