Definitions

  • the invention relates to a method for producing an insulating jacket, in particular for a water reservoir with an insulating layer and an outer layer, according to the preamble of patent claim 1.
  • Hot water storage or buffer storage for heating systems and similar devices must be isolated as best as possible to save energy.
  • Typical insulating materials are PU foams, since these have good insulating properties, are durable and easy to work with.
  • For the production of insulating foam mainly new material is used, which makes it much easier to control the production process and to produce high-quality end products.
  • a conventional insulating jacket is in EP 0 030 930 A described and illustrated.
  • This insulating jacket consists of a rigid polyurethane foam layer, on the inside of a soft foam layer is attached.
  • the soft foam layer has the task to compensate for dimensional tolerances and inaccuracies in order to prevent convection of air between the water reservoir and the insulating layer.
  • the known solution is unsatisfactory, since the use of composite material, the recyclability of the insulating jacket is much more difficult.
  • the existing inaccuracies may be somewhat compensated by the soft foam layer, but in particular at the connection points, flanges and the like, the insufficient accuracy of fit in practice regularly leads to problems.
  • the object of the present invention is to avoid these disadvantages and to provide a method which makes it possible to produce a high-quality insulating jacket from recycled material.
  • this object is achieved by a method in which the parts are processed after foaming at their abutment surfaces. It has namely, pointed out that the problem of dimensional tolerances, especially when using recycled materials particularly massive occurs and the tightly tolerated components can be produced in this way hardly.
  • the inventive solution it is now possible to produce high-precision fitting parts, which are adapted to avoid the cavities or joints to the corresponding water storage or the like. On special compensation layers to solve the problem of dimensional tolerances can be completely or at least largely dispensed with.
  • the machining takes place by producing a tongue and groove connection.
  • the processing can also be done by making a gradation.
  • Essential here is a certain overlap area, which ensures that joints can be safely excluded between the individual parts of the insulating jacket.
  • a particularly favorable embodiment of the method according to the invention provides that the processing takes place after cooling while maintaining a relaxation time. This fact takes into account the fact that, in particular with recycled materials, even after foaming, certain dimensional changes can occur.
  • the present invention relates to an insulating jacket, in particular for a water reservoir with an insulating layer and an outer layer.
  • this insulating jacket is characterized in that the insulating layer consists of recycled material and that the jacket consists of several mutually connectable parts, which are preferably machined at their abutment surfaces. With such an insulating jacket, it is possible to represent complex geometries with high precision.
  • a particularly advantageous solution is achieved if the insulating layer of recycled polyurethane with 3 to 25 wt% polyurethane binder, which preferably contains flame retardant agents. In this way, an ideal combination of high thermal insulation and advantageous overall properties can be achieved.
  • the insulating layer has a thickness which is between 50 mm and 200 mm.
  • the outer layer can consist of PVC (polyvinyl chloride) or PS (polystyrene).
  • the insulating jacket consists of an outer layer 1 within which an insulating layer 2 is arranged. With 3 the tongue and groove connection is marked at the joints of the individual parts. With 4 sealing strips are indicated, which may optionally be provided to effect an improved seal.
  • the ceiling insulation is labeled 5.
  • FIG. 3 differs from that of FIGS. 1 and 2 in that, instead of four parts, only three parts are provided which form the cylinder jacket of the insulation at uniform circumferential intervals.
  • the diameter of the cylindrical shell can have a diameter of 400 mm to 1500 mm depending on the application.
  • the ceiling insulation 5 By a precisely fitting cover, the ceiling insulation 5, the cylinder jacket is closed at the top.
  • the outer layer 1 can be made of aluminum or PET in order to obtain a robust and visually appealing exterior.
  • the individual parts are delivered loose and usually assembled at the installation site. The attachment takes place in a conventional manner by clamping rings.
  • the production process is as follows:
  • Old PU material polyurethane
  • Old PU material polyurethane
  • aggregates and PU virgin material are added, and the mixture is compressed in a mixing machine to a density between 40 kg / m 3 and 150 kg / m 3 .
  • the mixture is then reacted with hot air or steam, demolded after the ripening time and dried if necessary.
  • the shaping takes place in tools made of stainless steel. After cooling and maintaining a required relaxation time, the individual parts are precisely milled on the abutment surfaces in order to obtain highly accurate end products.
  • the outer layer is inserted into milled longitudinal slots of the insulation layer.
  • Fig. 4 shows in detail the exact structure at the joint.
  • a first part 6 is connected to a second part 7, wherein on the end face of the first part 6, a spring 8 is connected, which engages in a groove 9 of the second part 7.
  • the outer layer 1 surrounds the outer surfaces of the parts 6, 7, covers a part of the end face and is held in a groove 10, 11 of the part 6, 7.
  • the present invention makes it possible to process recycled waste to high quality products.
