Definitions

  • the invention relates to a mica-containing material made from expanded or expanded and unexpanded mica powder, which is applied to a support having flat openings, and to a method for producing the mica material and its use.
  • mica Because of its excellent insulation properties, mica has been used as an insulation material for some time.
  • DE 39 22 636 describes a heat shield for motor vehicles in which mica powder with water glass as a binder is applied to a substrate in layer form and then subsequently baked on the substrate by temperature treatment.
  • Another application is known from DE 35 12 842.
  • This document relates to a flat gasket made from a flat mica material.
  • the mica material itself consists of a large number of superimposed flat mica disks, a binder layer being introduced in the overlapping areas of the mica disks lying directly one above the other.
  • the mica disks are produced in such a way that mica raw material is split into mica layers by treatment with a reaction solution, possibly with the additional action of higher temperatures.
  • a carrier material for example a thin steel wire mesh
  • a disadvantage of the mica material described above for the sealing application is in particular that its production is very complex. As described above, it is namely necessary in this case that the mica disks are first produced from the mica powder by chemical treatment. These mica disks must then be subsequently provided with binders in order to connect them to the sealing material. Another disadvantage is that, due to the binder (synthetic resins), harmful emissions caused by decomposition of the organic binder cannot be prevented at higher temperatures.
  • the mica material according to the invention is thus distinguished by the fact that expanded or expanded and unexpanded mica powder is bound to a flat support body having openings. Surprisingly, it has been shown that a connection to the mica powder is only possible through the flat supporting body having openings.
  • the mica powder is here by clinging to one another and with the perforations. stabilizes the flat support body. Obviously, this is achieved by compressing the inflated individual layers during manufacture. It is particularly surprising that the composite has such a high strength that it can also be used without a binder for most applications. On the other hand, in this case the bond can be released again by a correspondingly long mechanical treatment, so that on the one hand the planar support body and on the other hand the mica powder can be recycled separately. Since the mica material in this embodiment also contains no binder, no emissions occur even at high temperatures (> 600/700 ° C). The manufacturing process is extremely cheap owing to the inexpensive products used, such as expanded mica powder and, for example, glass fiber fabric as the carrier body.
  • the carrier body is preferably used in the form of woven fabrics, grids, nets, braids, nonwovens or perforated sheets.
  • the material of the carrier bodies described above can consist of non-fibrous or fibrous material, such as, for example, glass, ceramic, plastic, metal, cellulose or carbon.
  • Support bodies which are already commercially available, such as glass fiber fabrics or nets, are preferably used here. It has been found in numerous tests that the opening width of the openings can be a maximum of up to 50 mm. However, it is preferred if the opening widths of the openings in the supporting bodies are in the range from 3 mm to 10 mm.
  • the web width, ie the areas between the openings, are preferably between 0.001 and 10 mm, particularly preferably between 0.1 and 5 mm. It is advantageous if the openings are evenly distributed over the supporting bodies.

  • mica powder also includes the degradation products of the mica, e.g. Understand vermiculite.
  • Vermiculite is a three-layer phyllosilicate (see Römpp Chemie Lexikon, 9th edition, volume 6, p. 4896). It has been shown that in particular these vermiculites, which are also commercially available, are particularly suitable.

It has been shown that such
