Flexible material web for cladding a · and / or SZ corner in buildings

The invention relates to a flexible material web for cladding and / or sealing purposes in buildings.

It is known to use copper foil as a particularly high-quality seal in buildings if necessary. Since such a seal must be chemically resistant to both acidic and alkaline substances and at the same time there are high requirements for good deformability, good sealing effect and high Resistance to aging, copper appeared to be particularly suitable for this application, as it was can meet the stated requirements as a whole.

However, it is disadvantageous! that the use of Copper for this purpose is very expensive.

Therefore, the invention was based on the object of a

for the purposes mentioned usable seal or Vei kleiuuag 2U BCiiäf part, all au the CueiäiBüueö and

Mechanical properties are met to a satisfactory extent and the requirements are significantly cheaper is.

To solve this problem, it is proposed according to the invention for an "M" + -eri "TLhATrn of the type mentioned that the The material web has an insert layer formed from a thin metal, that this insert layer is arranged between two bitumen layers and that between the insert layer and at least one of the two bitumen layers is provided with a plastic layer adhering to the insert layer, which consists of a material that is highly resistant to chemically aggressive substances.

The suggested web of material represents an extremely high quality Seal that fully meets all chemical and / or mechanical requirements and is much cheaper than the rest the previously used copper foil. Pure the metallic insert can e.g. Light metal or an aluminum alloy is used so that the use of an expensive precious metal is unnecessary. The bitumen layers can simply be '"id without large Raise effort; The same applies to the plastic layer on the metallic insert, e.g. by gluing, fusing or other materials adapted to the respective material Way. The thickness of the plastic layer is determined by the choice of material and can be between a few microns and a few millimeters.

It is also advantageous that the material web as a whole

very easy to process, e.g. by removing the material web slightly heated on a certain outside with the burner, so that the outer bitumen layer softens. It is then a good connection with the respective contact or support surface

guaranteed. In addition, the material web its structure and the materials used give it a good adaptability to shape, whereby it also has a beneficial effect that the material web, in contrast to a simple copper foil, has a comparatively precise thickness of a few millimeters, so that a precisely defined contact of the material web to all surfaces to be sealed and the presence of a relatively uniform protective layer of defined thickness is guaranteed _o

The on the metal insert it c, ■ · "-. A plastic layer that has been applied can advantageously be carried out after application in the liquid State of high temperature cured thermosetting resin be formed in a thickness between 5 and 100 microns, preferably between 30 and 50 microns.

It is also advantageous if the insert layer is covered by a thin Sheet metal or a metal foil of corrugated, corrugated, honeycomb-like or similar! * Deformation is formed, because this also improves the connection or adhesion to the bitumen layers, among other things.

In order to achieve a sufficient and good temperature resistance in the largest possible area, it is according to an M further proposal of the invention advantageous if at least

one of the two bitumen layers is formed from at least two types of bitumen with different softening and melting temperatures, and if these temperatures are chosen so " ^- 'Ch + in» ίπβΒ range from - 2Q G to + 100 ° C is temperature-resistant even over a long period of time. This results in a particularly versatile «usability of the material web.

It may also be advantageous if asbesi fibers are embedded in at least one of the two bitumen layers, which are suspended in the air.

In a further embodiment of the invention it is proposed that that in cJis Obsrssits there are one of the two * »bit.shifted Quartz gravel is embedded in a grain size of 1-2 mm. This storage can be done by rolling in the quartz gravel can serve as mechanical protection and, if necessary, even enable the material web to be walked on immediately. Furthermore, the quartz gravel prevents transitions between the bitumen and any asphalt that may be applied later.

While the metallic insert layer should have a thickness of 0.1-0.3 mm, the remaining layers in the ot thickness appropriately dimensioned so that it is suitable for the web of material gives a total thickness between 3 and 6 mm, preferably one Strength of 5 now.

An exemplary embodiment of the invention is illustrated below a drawing described in more detail. Show in detail:

1 shows a schematic section through a material web

of a particularly simple embodiment; 2 shows a schematic section through a modified embodiment of the material web.

The material web 1 shown in FIG. 1 has a metallic insert layer 2 which is provided with a plastic layer 3 on its upper side. The plastic layer 3 consists of a suitable synthetic resin and is applied at least to that side of the insert layer 2 on which attack by chemically aggressive substances from the outside must be expected. The adhesion between the plastic layer 3 ^{and the} insert layer 2 can be achieved in various ways, which also depends on the type of plastic, for example by gluing, by fusing, by welding, by hardening under the influence of heat or the like.

On the plastic layer 3 and the underside of the insert layer 2, in turn, a bitumen layer 4b or 5 is applied with good adhesion.

In Fig. 2, an improved embodiment 3 is shown at the one material web 6 aufweisi a metallic insert layer 7 These? consists of an aluminum alloy and has otherwise a wavy shape. On both sides of the insert layer 7, a thermosetting synthetic resin is applied in the liquid state and cured using a suitable baking temperature,

'each

a plastic layer 8 forms. Both layers of plastic have a corrugated shape like the inlet layer and are each covered with a layer of bitumen 9.

The bitumen layers 9 are each mixed from three different types of bitumen. For example, three bitumen fractions can be used which correspond to the DIN standard B GO / -, B 85/25 and B 105/15. It turns out that such a mixture results in a bitumen layer which is good in a relatively large temperature range Has persistence.

On top of the one bitumen layer 9 is a layer Rolled in from quartz gravel 10, which this side of the MaterIaIbalm 6 gives particularly good mechanical protection and can also be walked on immediately after processing the Material web 6 allows.

The thickness of the metallic insert layer 7 is, moreover, 0.2 mm.

From the description it follows, among other things, that the proposed material web is very versatile for sealing and / or lining purposes. Your flexibility is also large enough to allow the web of material to roll up before processing, e.g. for transport or Lagprzwecken is possible.
