Description
COMPOSITE ELEMENTS
*
Field of the invention
The invention relates to composite elements consisting of a core covered with a plastic sheet made of foam or a porous material.
BACKGROUND OF THE INVENTION
The composite elements made of a foam core surrounded by at least one outer layer are well known. They have decorative functions, although they are preferably used for thermal insulation, for example in buildings or in refrigeration equipment.
Refrigeration equipment is very important both in the commercial sector and in the private sector. It is mostly produced by manufacturing a cover into which is introduced a liquid mixture made of a rigid polyurethane foam system, and the system hardens on the cover to give the polyurethane.
"Vacuum insulation panels" also abbreviated as VIPs, have been used in recent times to reduce thermal conductivity. These, too, in !: their majority are introduced in the covers and are surrounded with rigid polyurethane foam.
These processes are inconvenient. Particularly when VIPs are incorporated, a fixation process is necessary.
During transport and during the subsequent handling, and also during the process of foaming around the VIPs, there is also the risk of damage to the VIPs, for example in the region of the welds.
The Permaskin process is a method known for the use of a plastic sheet to wrap substrates. It is described by way of example in WO 01/32400. :: |
Here, a molding is placed in a chamber between two thermoplastic sheets separated from each other, and fixed, and then the air is evacuated from the chamber, and the sheet is consequently compressed on the surface of the molding, while: ::: a gap between the sheets is maintained. The sheet here is preferably heated, in particular at a temperature above the softening point of the sheet.; '·;;' · The rigid polyurethane foams used- in 'the thermal insulation / low temperature sector too'; they can be used in theory as a substrate. The application [WO 2008/135550 describes this. The bilaterally coated rigid foam elements produced in this way exhibit an increased holding capacity, breaking strength,; and resistance to weathering, and also improved sensation ^ j and barrier action with respect to the ingress of liquids. :: The given example has a rigid foam made of Neopolen. Reference is made to the fact that foams can be used! 'of rigid polyurethane. The rigid foams used ?? ' you h!
no additional previously applied functional layer.
However, moldings produced in this manner have only inadequate long-term insulation properties, due to the gas exchange processes. In addition, the resistance to mechanical loads is only low, examples are loads that can be raised in contact with pointed articles or with sharp edges.
Description of the invention
The objective of the present invention was to provide composite elements which can be used for refrigeration equipment and which optionally allow the incorporation of VIPs. They are proposed for being easy to produce, and for having good mechanical resistance and low intrinsic weight. An additional intention is that it is possible to apply decorative layers.
Surprisingly, the objective was achieved through the content of the invention, particularly an elementary compound comprising; a) a core made of a foam or a porous material,
b) an outer layer applied to the core a), and, "c) a sheet made of a thermoplastic and which differs from the outer layer b).
The invention also provides for the production of the composite elements, and also the use thereof, 'in
particular to produce refrigeration equipment.
The core a) is preferably one selected from the group comprising foams and porous materials.
The foams a) are preferably selected from the group comprising melanin-formaldehyde foams, rigid open cell polyurethane foams, and rigid closed cell polyurethane foams.
The porous materials are preferably inorganic organic or inorganic polymers, hereinafter also referred to as monoliths. Among the monoliths, it is; gives particular preference to aerogels. Aerogels are gels which have pores and have dried under supercritical conditions. |, N
In a preferred embodiment of the invention, the core; it is a foam, in particular a rigid foam. The foams are foams of open cells or closed cells, and this varies with the application sector of the composite elements. The open cell foams may be melanin-formaldehyde foams or rigid polyurethane foams, preferably rigid polyurethane foams, and in particular rigid open cell polyurethane foams.
For the purposes of the invention, the rigid foams are foams of DIN 7726 (05/1982), where these are exhi: ben relatively high resistance to deformation under 'compressive load (compressive stress at a compression of '10%', " ";
compressive strength of DIN 53421, 06/1984, > 80 kPa).
The rigid polyurethane foams used as the core a) are known. Open cell foams, which can be evacuated, have also been described extensively, for example in EP 2072548. The foams can be used as core a) without further pretreatment. WO 2006/120183 says that the foam can be compressed to improve the ease of evacuation.
Melamine-formaldehyde foams are likewise known, for example from EP 74593. Products of this type are marketed by way of example by BASF SE as Basotect®.
Aerogels which can be used as core a): are described by way of example in WO 2007/065847.
The outer layer b) is preferably selected from the group comprising barrier layers with respect to the gases, also called diffusion barriers, where also "water vapor is considered as a gas, flame retardant layers, with mechanical support.
The diffusion barriers preferably involve waterproof sheets to water vapor and other gases.
Flame retardant barriers preferably involve thin-film mats made of mineral wool, layers; of alkali metal silicate, as described by way of example in WO 2006/040097, or layers made of other
Flame retardants, such as phosphorus, graphite, melanin, or antimony trioxide.

The metallized high barrier laminates are composed of at least two layers of Al in order to inhibit the entry of small molecules, for example water, as the diffusion trajectories extend. However, in the case of applications of thermal insulation of composite elements, the thickness of the metal layer should certainly not exceed a number of micrometers, otherwise heat loss through thermal bridging will occur. , and in particular through its dissipation in the corners, 'becomes excessive. ....
In a preferred embodiment of the invention, the outer layer: b ') is a sheet which completely encloses the: num: e'; or a). It is particularly preferable that the external layer b), which is described, is a sheet impervious to gas.

Examples of copolymers that can be used are alpha-olefins with C3-C20, preferably alpha-olefins with C3-C8.

For the process of the invention of the bilateral coating of the core a) with a plastic sheet is essential
what
- the molding is distributed and secured in a capsule between the sheets, with separation,
- the air is evacuated from the capsule, and
- the sheets are thus compressed on the opposite areas of the molding, while maintaining a vacuum between the sheets. This reduces the risk of surface defects, such as folds or misalignments.
The sheets c) can be applied on one side of the composite element. It is preferable that a sheet c) is applied on two opposite sides of the molding. The sheet c) here can be left at the edge of the molding, and in another embodiment of the invention the sheet c) may have to be bent over the molding edge. The sheet c) can also completely surround the molding.
The composite elements of the invention are versatile. By way of example, they can be used in the construction industry, for example in the thermal insulation of buildings. Plate c) here serves not only: for decorative purposes but also to protect the core a) from the effects of weathering.
The desired properties of the composite element can be achieved when desired, for example in relation to the flame retardation, by virtue of the different outer layers b).
The moldings of the invention can be used with particular advantage in the production of refrigeration equipment. The composite elements can be produced in the form of the walls and doors of the refrigeration equipment. Said components can then be assembled to give the finished cooling equipment, thereby considerably simplifying the production of the refrigeration equipment. Here again, the color and decorative effect of the cooling equipment can be varied through the sheet c). The protection of the surface can also be achieved.
The use of evacuated composite elements can further reduce the thermal conductivity of the refrigeration equipment.
