Description
A mineral fiber composition
This invention relates to a mineral fiber composition which is biodegradable, i.e. the fibers decompose as soon as they come in contact with a physiological milieu.
The prior art already describes some mineral fiber com¬ positions which are said to be biodegradable.
Biodegradability of mineral fiber compositions is of great importance since various studies indicate that mineral fibers with very small diameters in the range of under 3 mi¬ crons are suspected to be carcinogenic, while biodegradable mineral fibers with such dimensions show no carcinogenicity.
However, mineral fiber compositions must also have good workability by known methods for producing mineral wool with a small diameter, in particular the jet process or the exter¬ nal rotary process. This involves in particular a sufficient difference of e.g. 80° between the devitrification and proc¬ essing temperatures.
The mechanical and thermal properties of mineral fibers, or the products made therefrom, are also of crucial impor¬ tance. Mineral fibers are used for example for insulating purposes to a great extent. Sufficient temperature resistance of the mineral fibers is necessary in particular for use in the industrial sector.
The problem of the invention is to provide a novel min¬ eral fiber composition which is distinguished by high biode¬ gradability, has sufficient temperature resistance for appli¬ cation in the industrial sector, and can be fiberized well.
The invention is based on the finding that this problem can be solved by a mineral fiber composition which consists substantially of silicon dioxide and alkaline-earth oxides,
and further contains alkali oxides as a melting accelerator and a considerable proportion of iron oxide for increasing temperature resistance.
It has turned out that such mineral fiber compositions fulfill the combination of necessary properties, namely bio¬ degradability, sufficient temperature resistance for insu¬ lated objects in industry, as well as good workability in the production of the mineral wool as such and the products . This simultaneously means that the upper devitrification tempera¬ ture of the melt is preferably under 1300°C.
The subject of the invention is a mineral fiber composi¬ tion which is biodegradable, characterized by the following constituents in percent by weight:
Si02 45 to 55
AI2O3 0 to less than 4
Fe203 more than 7 to 15
CaO 18 to 35
MgO 5 to 15
Na20 + K20 0 to 10
P205 0 to 5
Impurities 0 to 2
The inventive mineral fiber compositions are readily drawable in particular by the jet process, i.e. one obtains a mineral wool with a low-shot content.
The mineral fibers reach a high temperature resistance of at least 1000°C according to DIN 4102, part 17.
Such mineral fibers show good biodegradability.
The mean fiber diameter is usually 1 to 15 microns, a range of 2.5 to 8 microns being preferred.
The addition of alkali oxides causes a melting point re¬ duction and therefore better workability in the melting proc¬ ess. Furthermore, up to 30% recycled glass can be used advan¬ tageously with a sodium-containing mineral wool composition.
The inventive mineral fiber compositions can preferably be melted in melting chambers fueled with fossile fuels, in particular natural gas, at melting temperatures from 1350 to 1450°C. Such melting chambers can produce a homogeneous melt, which is a prerequisite for constant product quality. Homoge¬ neity of the glass melt also facilitates the reproducibility of the fiberizing process and thus of the thermal and me¬ chanical product properties. Furthermore, the constant chemi¬ cal composition of the thus produced mineral wool leads to controllable biodegradability.
In particular the addition of iron oxide increases the temperature resistance of the mineral wool.
The inventive mineral fiber compositions preferably have the following constituents in percent by weight :
Si02 45 to 53
A1203 0.3 to 3.9
Fe2θ3 more than 7 to 13
CaO 20 to 25
MgO 10 to 15
Na20 + K20 3 to 8
Impurities 0 to 2
A content of silicon oxide in the range of 46 to 52% by weight is especially preferred.
With respect to the alkali oxides a range of 3 to 6% by weight is especially preferred. Iron oxide is preferably pre¬ sent in a range between 7,1 and 11% by weight.
To assess biological degradability the standard powder test of the German Glass Society was used. This is an easily conducted method and gives a sufficient measure of biological degradability when used with a simulated physiological lung fluid at 37°C. The method is described in L. Springer, "Laboratoriumsbuch fur die Glasindustrie" , 3rd edition, 1950, Halle/S: W. Knapp Verlag.
The thermal behavior of the mineral fibers was deter¬ mined by the so-called "Swedish method" . This method uses a silit pipe furnace with a horizontal working pipe open on both sides with a length of 350 mm and an inside diameter of 27 mm. In the center of the furnace there is a ceramic sup¬ porting plate with dimensions of 30 x 20 x 3 mm for position¬ ing the test sample. The test sample has dimensions of 12 x 12 x 12 mm or 12 mm ø x 12 mm height. The gross density is normally 100 kg/m3. The temperature increase is 5 K/min. The change in test sample height is determined continuously with a reading optic.
The invention will be described more closely in the fol¬ lowing using examples.

An investigation by the modified powder test of the Deutsche Glasgesellschaft yielded a value of 45 mg/kg and thus a value for high biodegradability.
