Definitions
- the present invention relates to an organopolysiloxane composition that can be vulcanized from room temperature to a polycondensation-crosslinking elastomer and does not contain alkyltin catalysts which have toxicity problems.
- the invention also relates to novel polycondensation catalysts in silicone chemistry and their use as catalysts for the polycondensation reaction of organopolysiloxanes.
- the formulations of the polycondensation-crosslinking elastomers generally involve a silicone oil, generally a hydroxyl-terminated polydimethylsiloxane, optionally prefunctionalized with a silane so as to have alkoxy ends, a crosslinking agent, a polycondensation catalyst, conventionally a tin salt or an alkyl titanate, a reinforcing filler and any other additives such as fillers, adhesion promoters, dyes, biocides, etc.
- RTV Room Temperature Vulcanisable
- water (either brought by atmospheric humidity in the case of RTV-I, or introduced into a part of the composition in the case of RTV-2) allows the polycondensation reaction, which leads to the formation of the elastomeric network.
- single component compositions crosslink when exposed to moisture in the air, i.e. they can not crosslink in a confined environment.
- the single-component silicone compositions used as mastics or adhesives cold-crosslink following a mechanism for hydrolysis of reactive functions of the acetoxysilane, cetimoxysilane, alkoxysilane, etc. type, followed by condensation reactions between formed silanol groups and other residual reactive functions. Hydrolysis is usually carried out by means of the water vapor diffusing into the material from the surface exposed to the atmosphere. Generally, the kinetics of the polycondensation reactions is extremely slow; these reactions are catalyzed by a suitable catalyst.
- catalysts As catalysts are used, it is most often used catalysts based on tin, titanium, an amine or compositions of these catalysts.
- the catalysts based on tin see in particular FR-A-2,557,582) and titanium (see in particular FR-A-2,786,497) are catalysts having a good efficiency.
- the two-component compositions When the two-component compositions, they are marketed and stored in the form of two components, a first component containing the base polymeric materials and the second component containing the catalyst. The two components are mixed during use and the crosslinked mixture in the form of a relatively hard elastomer.
- These two-component compositions are well known and are described in particular in the work of Walter NoIl "Chemistry and Technology of Silicones" 1968, 2nd edition on pages 395 to 398. These compositions essentially comprise 4 different ingredients:
- crosslinking agent generally a silicate or a polysilicate, a tin catalyst, and
- the condensation catalyst is based on an organic tin compound.
- tin catalysts have already been proposed as a crosslinking catalyst for these RTV-2.
- the most widely used compounds are alkyltin carboxylates such as tributyltain monooleate or dialkyltin dicarboxylates such as dibutyltin dilaurate, dibutyltin diacetate or dimethyltin dilaurate (see the book “Chemistry and Technology of NoIl”). silicones "page 337, Academy Press, 1968 - 2nd edition or patents EP 147 323 or EP 235 049).
- Titanium catalysts also widely used in RTV-I, however, have a major disadvantage: they have slower kinetics than tin catalysts. In addition, these catalysts are not usable in RTV-2 due to gelling problems.
- a catalyst of the polycondensation reaction of the organopolysiloxanes is the time of implementation ("pot-life” or “working time”), that is to say the time during which the composition can be used after mixing without curing. This time must be long enough to pe ⁇ nettre its use but short enough to obtain a moldable object manipulable no later than minutes or hours after its manufacture.
- the catalyst must therefore make it possible to obtain a good compromise between the time of use of the catalyzed mixture and the time at the end of which the molded object can be handled (these times depend on the intended application, for example the molding or the manufacture of joints).
- the catalyst must give the catalyzed mixture a spreading time that does not vary with the storage time.
- the essential objective of the present invention is therefore to find a catalytic system that can be used both in the crosslinking of the mono- and bi-component elastomer compositions.
- Another essential objective of the present invention is to provide a catalyst which continues to meet both the constraints of conservation, implementation and crosslinking of the two types of elastomeric compositions mono- and bi-components.
