Definitions

  • the present invention relates to a new composition, its application as an electrical insulator and as a solvent for carbonless copying paper.
  • the invention relates more particularly to insulating oils which are used in transformers and electric capacitors. Such oils are described, for example, in European patent EP 8251 and in US patent 4,523,044.
  • the Applicant has unexpectedly discovered that the dielectric properties of these insulating oils can be greatly improved when certain products are added in small proportion.
  • the present invention is a composition comprising at least one electrical insulating oil (A) and at least one product (B) having at least 6 carbon atoms, carrying an aldehyde function and having at most two OH groups.
  • Electrical insulating oil designates all products which can be used in electrical transformers and capacitors. These are liquid products at operating temperatures, i.e. between -40 and 100 ° C or as soon as the temperature exceeds a value between ambient and 100 ° C. These products have a resistivity at least equal to 1010 ⁇ cm and preferably greater than 1012 ⁇ cm.
  • the product (A) can also be a mixture of at least any two of the products mentioned above. All these products are purified for example on absorbers or on land, and optionally degassed to obtain sufficient resistivity.
  • the invention is particularly useful for the products described in US Pat. No. 4,523,044 which are compositions of polyarylalkane oligomers consisting of the mixture of two oligomers A and B.
  • the invention also applies in particular to the liquid dielectrics described in EP 8251 of formula: where n and y have the value 1 or 2 which can be mixed with one or more products of general formula: where a varies from 2 to 4, b varies from 0 to 2, and R is an aliphatic hydrocarbon radical containing from 1 to 3 carbon atoms, this mixture being added with an acid acceptor of the epoxidized oil or tetraphenyltin type in quantity between 0.001 and 10% and preferably from 0.01 to 0.3%.
  • the product (B) can be chosen from products having at least 6 carbon atoms and carrying an aldehyde function. It can also carry other functions but not more than two OH groups. We use for example:
  • the product (B) contains at least one phenyl, for example:
  • the proportion of (B) can be included within wide limits.
  • the amount of (B) is such that it can represent up to 1 to 5% by weight of the mixture of (A) and (B).
  • the amount of (B), expressed on the same basis is between 50 and 1000 ppm.
  • the product (B) can also be a mixture of at least two products having 6 carbon atoms and carrying an aldehyde function, one of these products may or may not contain a phenyl.
  • composition according to the invention may contain antioxidants, epoxides and other additives customary in dielectric liquids.
  • the present invention also relates to the process for the preparation of these compositions.
  • the present invention also relates to the application of this composition in transformers and electrical capacitors.
  • composition according to the invention can be used as a solvent for manufacturing pressure-sensitive recording materials such as carbonless copying paper.
  • pressure-sensitive recording materials such as carbonless copying paper.
  • Such techniques are described for example in the patents FR 2 257 432 (NCR), GB 1 346 364 (FUJI) and FR 2 157 587 (Monsanto).
  • the angle of loss (tan-delta) is one of the important characteristics of a dielectric liquid. It characterizes the electrical conduction of the liquid and must be as low as possible.
  • the increase in the tan-delta during this test is generally due to the appearance of ionic products of oxidation of the liquid (or its impurities).
  • the tests consist in manufacturing and impregnating models of capacitors and in subjecting these models to accelerated aging (high voltages and temperatures).
  • the main sanction of the test is the number of capacitors which are deteriorated (breakdowns) during the test.
  • two series of 10 capacitors were made, comprising 2 films of smooth polypropylene 12 ⁇ m thick (24 ⁇ m in total) and a layer of kraft paper, 12 ⁇ m thick, located between the two films.
  • the paper has a density of 1.0.
  • the two series of 10 capacitors were impregnated using A1 and A1 + 200 ppm of B1 respectively.
  • the capacitance and tan-delta values of the capacitors at the temperature of 85 ° C. were measured, under the voltage of 1000 AC.
  • the capacitors were then subjected to aging at 85 ° C at 2700 V (75.0 V / ⁇ m) for 535 hours.
  • the tan-delta of all the remaining capacitors was measured as a function of the voltage at the temperature of 85 ° C.
  • the Tan-delta of the group of A1 capacitors comprising aldehyde B1 is significantly lower than that of the reference group A1 without this additive. (Reminder: the result is all the more favorable the lower the tan-delta).
