Definitions
- the present invention relates to the field of insulating resins for composite insulators.
- the term "insulating resin system” includes and / or encompasses in particular a (preferably low-viscosity) impregnating resin system based on epoxy resin and anhydride component with controlled reactivity Resin still other components (such as the inorganic oxide nanoparticles) may be present.
- epoxy in particular, that as an off ⁇ transition component - in particular a main component -.
- An epoxide is used this case, all can be used well-known in the prior art materials, are preferred - without it, to be limited - substances selected from the group comprising epoxy resins based on bisphenol A, bisphenol F, cycloaliphatic epoxides (in particular selected from the group comprising bis (2, 3-epoxycyclopentyl) ethers, 2,3-Epoxycyclopentylglycidylether, 1, 2 Bis (2,3-epoxycyclopentoxy) ethane, 3,4-epoxycyclohexylmethyl-3 ', 4'-epoxycyclohexanecarboxylate or mixtures thereof), glycidyl ester resins, and mixtures thereof
- the proportion of the inorganic oxide nanoparticles in the resin is from> 0.1% by weight to 10% by weight. This has proved to be favorable for many applications because often the favorable properties of the insulating resin can be achieved without the other properties (e.g.

- a particularly preferred material is Al 2 O 3 , as it has been shown for many applications when using this material that the resulting insulating resin is largely resistant to ⁇ over decomposition products of SF 6 . This represents an important secondary aspect for many applications of the present invention, so that Al 2 O 3 is preferred insofar as the invention is not limited thereto.
- the inorganic oxide nanoparticles are produced by a plasma process. This has proved favorable for many applications.
- the inorganic oxide nanoparticles can have a round in Wesentli ⁇ chen shape, but the invention is not so limited.
- the inorganic oxide nanoparticles may be sharp-edged and / or in platelets and / or wire form.
- the inorganic oxide nanoparticles are introduced into the resin according to a preferred embodiment by stirring, rolling and / or by using a turbomixer. Possibly.
- additives may be added to prevent agglomeration, although this has not been found necessary in many applications of the invention.
- the inorganic oxide nanoparticles may be provided with adhesion promoters (such as silane compounds).
- the starting materials constituting the insulating resin system comprise a hardener component.
- the hardener component is preferably selected from the group comprising phthalic anhydride, tetrahydrophthalic anhydride, methylnadic anhydride, hydrogenated methylnadic anhydride, methylhexahydrophthalic anhydride, hexahydrophthalic anhydride, methyltetrahydrophthalic anhydride and derivatives thereof and mixtures thereof. Particular preference is given to methylhexahydrophthalic anhydride, hexahydrophthalic anhydride, methyltetrahydrophthalic anhydride or mixtures thereof.
- the starting materials constituting the insulating resin system comprise an accelerator component.
- the accelerator component is selected from the group consisting of dialkylarylamine, Diarylalkylamine and Mi ⁇ mixtures thereof; Dimethylbenzylamine is particularly preferred.
- aryl or “alkyl” is understood to mean, in particular, the following functionalities: Alkyl: linear and branched C 1 -C 6 -alkyl, in particular
- Aryl selected from the group comprising: phenyl; biphenyl; Naphthalenyl; anthracenyl; Phenanthrenyl, benzyl
- the insulating resin system according to the invention may additionally contain additional components such as thinners, defoamers, adhesion promoters, flexibilizers. In this case, all known in the prior art materials can be used.
- the present invention also relates to a Iso ⁇ lierteil containing a Isolierharzsystem according to the vorlie ⁇ constricting invention.
- insulating member in particular to an insulating ⁇ collectively
- a Isolierharzsystem and a roving and / or fabric based on polyester, glass or aramid.
- the term "embedded” includes and / or includes in particular that the roving and / or tissue is impregnated with the resin. From dielektri ⁇ reasons a vacuum impregnation is preferred.
- the insulating resin system is prepared in a curing process comprising a curing step at> 50 ° C, preferably 70 ° C and a curing time of> 1 h, preferably ⁇ 2 h. Subsequently, preferably, a post-curing at> 150 ° C u. a curing time of> 10h, most preferably ⁇ 16 h.
- the present invention also relates to the use of a ⁇ Ver Isolierharzsystems comprising an epoxy-based resin and inorganic oxide nanoparticles as insulating material in electrical switchgear ⁇ .
- the present invention is - purely illustrative and not restrictive - examined using the present inventive example I.
- a resin was produced, composed of the following components:
- the resin was mixed with 3% by weight of Al 2 O 3 nanoparticles (diameter about 100 nm)
- a comparative resin (not according to the invention) was prepared; this corresponded to the resin system according to the invention, except that no nanoparticles were added.
