Definitions
- the field of the invention is that of formulations for treating supports in order to give them resistance to aqueous and fatty substances. More particularly, the invention relates to silicone compositions containing perhalogenated - preferably perfluorinated - radicals which can be used in particular for the production of hydrophobic and / or oleophobic coatings and / or impregnations, of various supports.
- the invention relates to crosslinkable silicone compositions, capable of being used as fluorinated finishes, in the textile field to provide the treated fabrics with waterproofing, and anti-stain and / or anti-fouling properties, combined with a easy to wash.
- Such properties are also advantageous for fields other than the textile field.
- the silicone oils grafted with fluorinated units can also be used as a lubricant, as a specific anti-adherent agent with respect to certain adhesives (silicones with high adhesive power), as an anti-greasy agent, or even as an anti- foam. They can also be formulated with different thickeners to form sealants or any other sealing and / or jointing materials. In crosslinked form, these fluorinated silicones can be formed into various technical parts by molding or by extrusion.
- the present invention relates to crosslinkable silicone compositions comprising linear or cyclic perhalogenated, preferably perfluorinated, polyorganosiloxanes, having at least one silicon atom substituted by at least one perfluorinated radical Rf.
- the present invention also relates to this water-repellent and oil-repellent perfluorinated silicone composition, in crosslinked form.
- the invention relates to precursors of coatings, coatings, paints or other varnishes comprising this composition.
- halogens and in particular fluorine and the carbon / fluorine bond in providing specific properties to organic polymer systems, is a well-known concept in polymer chemistry. It is known in particular that fluorination, and more precisely the introduction of perfluorinated units into polymers, brings about a reduction in surface energies, an improvement in thermal and chemical stability as well as hydrophobicity, organophobia and d 'oleophobia. It is thus known that in order to resist aqueous and fatty substances, a coating must have a high density of perfluorinated end groups Rf at the surface. Since the 1970s, this type of functionalization by perfluorination has been applied to silicone polymers, in particular of the linear or cyclic polyorganosiloxane (POS) type; preferably linear.
- POS polyorganosiloxane
- a perfluorinated dihalogenoorganosilane which can be hydrolyzed so as to produce a functionalized silicone, which can be, for example, a cyclic tetramer.
- a non-negligible drawback of these cobalt-based complexes is that they catalyze reactions other than hydrosilylation. In particular, they can participate in polymerization processes by breaking of epoxy rings. This lack of specificity is particularly troublesome. In addition, these catalysts are not industrial.
- US Patent No. 5,348,769 discloses linear or cyclic polyorganosiloxanes, comprising siloxy units D substituted by a first perfluorinated functional unit of formula -R- ZRf as well as other siloxy units D, carrying a second type of unit functional of the etherhydroxyl or alkylhydroxyl type.
- the catalyst used is preferably chloroplatinic acid. Such a technique is not very simple, because it requires the prior preparation of the olefinic reagent perfluoroalkylated. This significantly lengthens the synthesis times and consequently it increases the cost price of the process.
- POS - ⁇ alkyl esterfluorinated do not have optimal properties with regard to the lowering of surface tension as well as oleophobia and hydrophobia.
- European patent application No. 0 640 644 describes, for its part, perfluorinated silicone derivatives (Rf), which can be used in cosmetic formulations. These perfluorinated silicone derivatives are characterized by D siloxyl units, carrying perfluorinated grafts of three different types, namely:
- These POS can respond, eg to the following formula:
- POSs can be used in the formulation of antifoams of lubricants, anti-adhesion agents, agents for reducing surface tension, anti-fouling agents, oleophobic and / or hydrophobic agents or raw materials for the production of elastomers or films resistant to chemical attack and to solvents.
- One of the essential objectives of the present invention is to improve the perfluorinated silicone (co-) polymers according to the prior art and in particular according to FR 95 09 269:
- perfluorinated silicone systems are not sensitive to external aggressions (solubilization / extraction due to washing or the action of abrasives), so as to preserve their desired properties of lowering the surface tension at the origin of their waterproofing, anti-stain and anti-soiling functions.
- external aggressions have the direct impact of eliminating perfluorinated groups on the surface.
- this surface localization of said Rf groups is essential to their effectiveness.
- a crosslinkable silicone system comprising POSs carrying perhalogenated Gf grafts, preferably perfluorinated, judiciously selected from perfluorinated esters of dicarboxylic acids capable of forming anhydrides (eg maleic acid).
- Gf grafts are called bifid Rf grafts.
