초록

A mat for supporting a monolith, the mat comprising one or more first portions comprising fibers at least partially coated with an erosion resistant inorganic (e.g. silica) gel composition or a precursor thereof.

대표청구항 ▼

1. A mounting mat comprising one or more first portions comprising fibres at least partially coated with a silica precursor, which forms an erosion resistant inorganic gel composition on the fibres, wherein said silica precursor comprises a compound having the general formula: where R1 to R4 are the same or different and may comprise H or substituted or unsubstituted alkyl chains. 2. A mat according to claim 1, wherein a major surface area of the first portion or portions comprises less than 80% of the major surface area of the mat. 3. A mat according to claim 2, wherein the major surface area of the first portion or portions comprises less than 40%, less than 30%, less than 20% or less than 10% of the major surface area of the mat. 4. A mat according to claim 1, wherein at least part of the first portion is adjacent at least part of an intended leading edge of the mat. 5. A mat according to claim 1, wherein one or each of said at least one first portions extend through at least a part of an entire thickness of the mat. 6. A mat according to claim 1, wherein the mat comprises a plurality of the first portions. 7. A mat according to claim 6, wherein the first portions are arranged in a random or regular pattern across a major surface of the mat. 8. A mat according to claim 6, wherein the plurality of first portions comprise columns of the erosion resistant inorganic gel composition, which columns extend through part or substantially all of a thickness of the mat. 9. A mat according to claim 8, wherein the columns are arranged in a regular pattern, each first column being between 1 mm and 50 mm from its nearest neighbour or neighbours. 10. A mat according to claim 1, wherein at least part of the mat comprises an erosion resistant material and wherein the mat undergoes 28 mm2 or less of erosion when subjected to Erosion Test 1 and the mat undergoes 50 mm2 or less of erosion when subjected to Erosion Test 2. 11. A mat according to claim 1, wherein the mat has a minimum wrapping diameter of less than 100 mm according to Flexibility Test 1 and a flexibility of less than 180 mm2N−1 according to Flexibility Test 2. 12. A catalytic convertor comprising the mounting mat of claim 1. 13. A catalytic convertor comprising the mounting mat of claim 1, wherein the inorganic gel composition comprises a silica compound or silicone polymer or gel, formed on the fibres by an acid or base catalysed reaction of a silica precursor. 14. A mat according to claim 1, wherein at least part of the mat comprises an erosion resistant material and wherein the mat undergoes 28 mm2 or less of erosion when subjected to Erosion Test 1 or the mat undergoes 50 mm2 or less of erosion when subjected to Erosion Test 2. 15. A mat according to claim 1, wherein the mat has a minimum wrapping diameter of less than 100 mm according to Flexibility Test 1 or a flexibility of less than 180 mm2N−1 according to Flexibility Test 2. 16. The mat according to claim 1, further comprising a second portion substantially free from said silica precursor. 17. The mat according to claim 1, wherein said silica precursor forms an erosion resistant inorganic gel composition on the fibres by an acid or base catalyzed reaction.
