Abstract

In mfr. of building components, partic. insulating boards for thermal or sound insulation, foamed starch is used, mixed with natural building materials that are rapidly broken down by biological means, e.g. wood, cork, hemp, and other natural fibre materials. As rigid foam, the mixt. can be used for building blocks or for doors. ADVANTAGE - Relatively low cost, easily disposable.

Description

Die Erfindung bezieht sich auf ein unter Verwendung verschäumter Stärke hergestelltes Bauelement.The invention relates to a foamed using Starch made component.

Es ist bekannt, in der Bautechnik Bauelemente, insbesondere Dämm-Platten, -Matten oder dergleichen zur Wärme- oder Schalldämmung, unter Verwendung poröser Kunstharze herzustel­ len. Diese unterliegen als Abfall in der Regel, wenn über­ haupt, nur einer sehr langsamen Zersetzung zu einfacheren Stoffen, wobei sich häufig umweltschädliche Zersetzungspro­ dukte ergeben.It is known in construction engineering, in particular Insulation boards, mats or the like for heat or Soundproofing, using porous synthetic resins len. These are usually subject to waste when over at all, just a very slow decomposition to simplify Substances, where often environmentally harmful decomposition pro products result.

Ferner sind gattungsgemäße Bauelemente aus der DE-PS 32 06 751 bekannt. Hierbei handelt es sich um Schaumplatten aus Stärkeschaum, oder es wird Stärkeschaum als Füllstoff für Verpackungs- und Gipsplatten verwendet. Stärke läßt sich nach herkömmlichen Verfahren in großen Mengen aus pflanzli­ chen Rohstoffen herstellen und zu hart- bis weichelastischem Schaumstoff verarbeiten. Sie ist im Abfall leicht und rasch biologisch durch Mikroben ohne umweltschädliche Rückstände zersetzbar, wobei sie das mikrobielle Wachstum selbst för­ dert.Furthermore, generic components from DE-PS 32 06 751 known. These are foam sheets from starch foam, or it becomes starch foam as a filler used for packaging and plasterboard. Strength can be by conventional methods in large quantities from vegetable Chen raw materials and hard to soft elastic Process foam. It is easy and quick to waste biologically by microbes without environmentally harmful residues decomposable, thereby promoting microbial growth itself different.

Bauelemente im wesentlichen nur aus Stärkeschaum herzustel­ len, ist jedoch kostspielig. Components essentially only from starch foam len, but is expensive.  

Der Erfindung liegt die Aufgabe zugrunde, ein Bauelement der gattungsgemäßen Art anzugeben, bei dem die Zersetzung im Abfall (Müll) rasch und ohne umweltschädliche Zersetzungs­ produkte erfolgt, dessen Herstellung jedoch einfacher ist.The invention has for its object a component of the generic type in which the decomposition in waste (rubbish) quickly and without environmentally harmful decomposition products, but their manufacture is simpler.

Erfindungsgemäß ist diese Aufgabe dadurch gelöst, daß die verschäumte Stärke mit Natur-Baustoffen, die biologisch rasch abbaubar sind, vermischt ist.According to the invention this object is achieved in that the foamed starch with natural building materials that are biologically quick are degradable, is mixed.

Bei dieser Lösung ist es möglich, den Anteil der verschäum­ ten Stärke geringer zu halten und als Zusatz auf andere Na­ tur-Baustoffe zurückzugreifen, z. B. Holz, Kork, Hanf, andere Naturfaserstoffe und dergleichen. Ein solches Bauelement ist nicht nur weniger kostspielig, sondern läßt sich auch weiter­ hin rasch biologisch ohne umweltschädliche Rückstände ab­ bauen.With this solution it is possible to increase the proportion of foaming to keep the starch lower and as an additive to other Na to use tur building materials, e.g. B. wood, cork, hemp, others Natural fibers and the like. Such a component is not only less expensive, but can also be further expanded quickly biodegradable without environmentally harmful residues to build.

Aufgrund ihrer porösen Struktur ist verschäumte Stärke beson­ ders für Dämm-Bauelemente geeignet, z. B. für Dämm-Platten oder -Matten zur Wärme- oder Schalldämmmung.Foamed starch is special due to its porous structure particularly suitable for insulation components, e.g. B. for insulation boards or mats for heat or sound insulation.

Als Hart-Schaumstoff kann sie auch für stützende oder tra­ gende Bauelemente verwendet werden, z. B. für Bausteine in der Bautechnik.As a rigid foam, it can also be used for supportive or tra ing components are used, for. B. for blocks in of construction technology.

Insbesondere kann das Bauelement mit der verschäumten Stärke verfüllt sein, z. B. in Form einer Tür mit Füllung.In particular, the component with the foamed thickness be filled, e.g. B. in the form of a door with filling.
