Definitions

  • the present invention relates to a fiber part according to the preamble of claim 1, a method for producing a molded part according to the preamble of claim 10 and a use of a carbon dioxide-curing binder for producing a molded part from fibers.
  • a fiber part, in particular a molded part, for the purposes of the present invention is used in particular for heat or heat insulation and / or storage or covering, preferably in exhaust systems of an internal combustion engine or motor vehicle, in the engine compartment of a motor vehicle or the like, for example, an element of an exhaust system, in particular an elbow, a front pipe, an inlet hopper, a particulate filter, a catalyst, a monolith, a muffler or the like.
  • the present invention relates in particular to fiber parts, which are used at higher or elevated temperatures, preferably greater than 200 0 C, in particular of about 300 ° C to 1100 0 C or higher.
  • the present invention has for its object to provide a fiber part, a method for producing a fiber part and a use of a carbon dioxide-curing binder for producing a molded part, so that a simple and inexpensive production of a molded part of fibers or a fiber part is made possible.
  • One aspect of the present invention is to use a binder for the fibers which cures under carbon dioxide. This leads to several advantages.
  • the proposed binder allows a simple and inexpensive production of a molded part from the fibers.
  • solidification can be achieved very quickly, for example within 60 seconds. This allows compared to the prior art lower cycle times and higher productivity for example, the same number of molds gene.
  • Another advantage is that in principle no heating for curing of the binder - that is, for solidification of the fiber part or the fibers to the fiber molding - is required. This noticeably reduces the energy expenditure compared with the prior art. Furthermore, this is beneficial for shorter cycle times, since a warm-up and cooling can be omitted.
  • a certain (small) heating for example to about 50 to 100 ° C, in particular about 70 0 C, possible to accelerate the hardening of the binder (further).
  • the binder contains or consists of at least one phenolic resin. Particular preference is given to using a resol.
  • the term "by carbon dioxide” is to be understood as meaning that a gas is used which contains or consists of carbon dioxide of at least 25% by volume, preferably at least 50% by volume. Either it is sufficient to expose the fiber part or binder to be cured to this gas, in particular by displacing the normal air. Particularly preferably, the fiber part or binder is flowed through by the gas.
  • Fig. 1 is a schematic representation of a proposed production of a proposed fiber part
  • FIG. 2 shows a schematic representation of the production of a molded part from the fiber part or from fibers provided with binder.
  • FIG. 1 illustrates, in a schematic diagram only, a preferred production of a proposed fiber part 1, in particular of mineral or heat-resistant fibers 2.

  • the fiber part 1 is not further tailored or shaped and is in particular in endless form or as wool or the like before.
  • the fibers 2 used are preferably glass fibers, in particular E or ECR glass fibers.
  • other mineral fibers in particular silicate fibers or calcium silicate fibers, can also be used.
  • the fibers 2 are heat-resistant at least to 300 ° C., preferably high-temperature resistant, preferably up to 600 ° C., in particular up to 800 ° C., very particularly preferably up to 1100 ° C. or more.
  • the fibers 2 are preferably drawn endlessly from a melt and have a constant diameter.
  • the fiber diameter is at least 3 microns, preferably at least 4 microns and more preferably at least 6 microns or more. According to a very particularly preferred embodiment, the diameter is substantially 9 to 10 microns with a tolerance of at most 3 microns.
  • the fibers 2 are preferably - as already mentioned - continuous filaments.
  • the fiber part 1 can basically also be formed from fibers of finite or specific length. Alternatively or additionally, the endless fibers 2 can also be cut. Furthermore, during fabrication and cutting of the fiber part 1, a shortening of the fibers 2 takes place anyway.
  • the fiber part 1 furthermore has a binder 3 which is applied, for example sprayed on, in particular to the fibers 2, for example in liquid or dry form or in any other suitable form.
  • the fibers 2 are preferably textured, in particular by means of a nozzle 4, as indicated in FIG. 1.
  • the fibers 2 initially present as fiber strand are textured by supplied gas, for example compressed air, and output, in particular, wool-like.
  • the binder 3 is preferably added during the texturing, in particular in the nozzle 4 or by means of the nozzle 4 or through a separate or integrated nozzle, in particular sprayed on or otherwise applied to the fibers 2.
  • the fibers 2 need not be completely covered by the binder 3, although this may be desirable. However, at least partial covering, wetting or adhesion of binder 3 is preferably sufficient.
  • the binder 3 preferably cures quickly by carbon dioxide - that is, under the action of carbon dioxide.
  • the binder 3 contains in particular at least one corresponding phenolic resin, more preferably at least one resol.
  • the phenol resin or resol as binder 3 available under the trade name "Carbophen” from Wilsontenes Albertus Chemische Werke GmbH, Dusseldorf, Germany, or under the trade name "SuperEko 2000” from Erg-Odlew, Poland

  • the mold 5 is filled with the particular wool-like, not solidified fiber part 1 or the preferably wooleartig present fibers 2 with the binder 3. The mold 5 then gives the desired shape.
  • a gas containing or consisting of carbon dioxide fed via an inlet 7 to the interior of the mold 5 and the shaped fiber part 1 and for example via an optional outlet 8 again led off.
  • the fiber part 1 is traversed by the carbon dioxide or gas.
  • the interior of the mold 5 or the fiber part 1 is flooded with gas containing only carbon dioxide or carbon dioxide, ie, it does not flow through continuously.
