Definitions
- the invention relates to a cement, in particular a grouting cement for joining a plurality of filter blocks of a filter body, in particular for an exhaust gas particle filter of an internal combustion engine of a motor vehicle, and in particular a cement intended to form a peripheral coating of the lateral surface of such a filter body.
- the invention also relates to a filter body comprising a plurality of filter blocks secured by means of a seal interposed between said filter blocks and shaped so as to oppose the passage of said exhaust gases between said filter blocks, in which the seal is obtained by curing a cement according to the invention.
- a particle filter 1 is shown in FIG. 1 in cross-section along the section plane B-B shown in FIG. 2, and in FIG. 2 in longitudinal section along the sectional plane A-A shown in FIG.
- the particulate filter 1 conventionally comprises at least one filter body 3, of length L, inserted into a metal casing 5.
- the filter body 3 may be monolithic. To improve its thermomechanical resistance, in particular during the regeneration phases, however, it has proved advantageous that it results from the assembly and machining of a plurality of blocks 1 1, referenced 1 1 a-1 1 i.
- a ceramic material cordierite, silicon carbide, etc.
- the extruded porous structure conventionally has the shape of a rectangular parallelepiped extending between two upstream faces 12 and downstream 13 substantially square on which open a plurality of channels 14 adjacent, rectilinear, and parallel.
- the extruded porous structures are alternately plugged on the upstream face 12 or on the downstream face 13 by upstream 15s and downstream 15e plugs, respectively, as is well known, to form channels of types
- the inlet 14e and exit 14s channels thus define interior spaces 20e and 20s delimited by a side wall 22e and 22s, a closure cap 15e and 15s, and an opening 19s or 19e opening outwards, respectively .
- Two input channels 14e and 14s adjacent output are in fluid communication by the common part of their side walls 22e and 22s.
- the blocks 1 1 a-1 1 i are assembled together by bonding by means of seals 27 made of ceramic cement generally made of silica and / or silicon carbide and / or aluminum nitride.
- seals 27 made of ceramic cement generally made of silica and / or silicon carbide and / or aluminum nitride.
- the assembly thus formed can then be machined to take, for example, a round section.
- a peripheral coating 27 ' also called “coating” is also applied so as to cover substantially the entire lateral surface of the filter body.
- the flow F of the exhaust gases enters the filter body 3 through the openings 19e of the inlet channels 14e, passes through the filtering side walls of these channels to join the channels exit 14s, then escapes to the outside through the openings 19s.
- the particles, or "soot" accumulated in the channels of the filter body 3 increase the pressure drop due to the filter body 3 and thus impair the performance of the engine. For this reason, the filter body must be regenerated regularly, for example every 500 kilometers
- Regeneration or "declogging" consists of oxidizing the soot. To do this, it is necessary to heat them to a temperature that allows them to ignite.
- the inhomogeneity of the temperatures within the filter body 3 and the possible differences in the nature of the materials used for the filter blocks 1 1 -a 1 1 i and the seals 27 and 28 can then generate high thermomechanical stresses, which may be origin of cracks in the joints and / or in the filter blocks 1a-1 1 i, decreasing the life of the particulate filter 1.
- the material of the seals 27 and 28 must therefore have a good mechanical strength at low temperature, that is to say between 400 and 500 ° C, and at high temperature, that is to say at temperatures above 1100 ° C.
- jointing cements comprising between 30 and 60% by weight of silicon carbide are known.
- Silicon carbide has a high thermal conductivity advantageously to homogenize the heat transfer.
- Silicon carbide has a relatively high coefficient of expansion.
- the silicon carbide content of these grouting cements must therefore be limited to ensure thermomechanical resistance suitable for application to particulate filters.
- EP 1 479 881 discloses a grouting cement with resin amounts substantially greater than 5% in order to adjust the porosity.
- the high quantities of thermosetting resin give the wet cement a consistency which, under the industrial conditions of use, prevents a regular spreading, and therefore a homogeneous distribution of the cement between the filter blocks.
- the filter body obtained by assembling filter blocks using such a cement therefore has insufficient mechanical strength for the canning operation, that is to say the installation of the filter body in the exhaust line. .
- high levels of thermosetting resin lead to the appearance of cracks during drying, debinding or cooking operations.
- these resins generally generate environmentally harmful products during debinding and high amounts of resin make it difficult to control these harmful products under industrial conditions.
- the object of the present invention is to provide a cement for producing a new seal material having improved adhesion, or having a satisfactory thermomechanical resistance but without ceramic fibers and / or with a high silicon carbide content.
- this goal is achieved by means of a cement, in particular a grouting cement, in particular intended for joining a plurality of filtering blocks of a filter body of an exhaust gas particulate filter.
- a cement in particular a grouting cement, in particular intended for joining a plurality of filtering blocks of a filter body of an exhaust gas particulate filter.

- the cement according to the invention may comprise clay, in particular a refractory clay of the ball-clays, bentonite or even kaolin type.
- Clay is indeed classically added to increase the strength of the joint after drying. However, it involves high amounts of water in the cement, and therefore an increased risk of cracking.
- the presence of thermosetting resin in the cement advantageously reduces the amount of clay while ensuring acceptable adhesion.
- the cement also comprises between 0.1 and 0.5% by weight of a dispersant, in percentage by weight relative to the total mass of the mineral material, excluding any water, and the thermosetting resin.
