Definitions

  • This invention relates to inorganic fibre compositions, and in particular to alkaline earth aluminosilicate fibres.

  • Such fibres may be used in support structures for catalyst bodies in pollution control devices such as automotive exhaust system catalytic converters and diesel particulate filters and may be used in the catalyst bodies themselves.
  • Such fibres may be used as a constituent of friction materials [e.g. for automotive brakes].
  • the fibres of the present invention have a range of properties and may be usable in any or all of these applications depending on the properties shown.

  • the fibres disclosed therein exhibit a low shrinkage at elevated temperature, and a high resilience at temperature, and also have the virtue of having a degree of solubility in body fluids which is significantly higher than the solubility of pure mullite fibres.
  • there is a trade-off in these requirements with the invention disclosed therein permitting the production of highly refractory- slightly soluble materials at one extreme to very soluble -reasonably refractory materials at the other with a range of characteristics in between.
  • sol-gel fibres which may yield both improved biosolubility and mechanical strength for applications taking place at 650°C, which conveniently is a temperature useful for certain automotive applications of inorganic fibres.
  • the present invention provides alkaline earth aluminosilicate fibres having a composition comprising:
  • alkaline earth metal oxide content of between 12 wt% and 20 wt%
  • compositions of the names of oxides e.g. alumina, silica, quicklime, calcia, strontia
  • alumina, silica, quicklime, calcia, strontia refers to the composition of the final fibre expressing the relevant elements as oxides.
  • the materials concerned may be provided in whole or in part as mixed oxides, compounded with fugitive components [e.g. supplied as carbonates] or indeed as non-oxide components [e.g. as halides].
  • a number of compositions were made by forming various aluminosilicate compositions comprising alkaline earth oxide additives. Except for such differences as highlighted below, the manufacturing method was similar to that of the fibres disclosed in PCT application no.

  • An aluminium chlorohydrate was used as the source of alumina.
  • a mixture of siloxane and colloidal silica sol acted as a source of silica.

  • soluble salts include salts such as chlorides or nitrates [e.g calcium nitrate tetrahydrate, strontium nitrate, magnesium nitrate hexahydrate, potassium chloride].
  • Sol is extruded through 300 x 0.2 mm holes spaced evenly around the periphery of a disc rotating at 2600 r.p.m. Air at 15°C and 45% relative humidity is blown through an annular orifice past the disc to attenuate the sol streams.

This has the beneficial effect of controlling the level of crystallisation in the fibres, and in particular the ratio of ⁇ -alumina crystals to amorphous material in the fibres. Limiting crystallisation helps to ensure improved biosolubility of the fibres produced. Comparative fibre As well as producing fibres as outlined above, comparative fibres were obtained from various sources. Two known fibres were obtained from commercial sources.
  • a third comparative fibre comprising 70% alumina, 19% alumina, and 11% calcia by weight, was produced based on the methods of fibre production disclosed in disclosed in PCT application no. WO 2007/054697. This will be referred to subsequently as the "PCT" fibre.

  • the source of silica in the sol gel consisted of a 50:50 mixture by mass of siloxane and colloidal silica, the colloidal silica in question being marketed under the brand name "Ludox CL” (30 wt% suspension of silica in water, pH 4.5).
  • the colloidal silica in question was that marketed under the brand name "Levasil 200S” in a 50:50 mixture of Levasil to siloxane.

  • Levasil 200S has a comparable silica concentration and pH to Ludox CL, but whereas Levasil 200S provides silica with an average particle size of 15nm and provides aluminium salts as a counter ion, Ludox CL provides silica with an average particle size of 12nm and has provides chloride as a counter ion. These factors may be related to the difference in performance.
  • Comparative fibres and fibres according to the present invention were assessed on mechanical resilience through a hot cyclic compression test, in which the materials were subjected to cyclic compression between two different pressures at 650°C and the retained force measured; the more force retained, the more resilient the material.
  • Static solubility (normalised and otherwise) and flow through solubility measurements were also made in accordance with the procedure set out in WO2008/065363, save that the test proceeded for 24 hours instead of 5 hours due to the lower solubility of the fibres involved.
