- This type of analysis consisting of burning samples in the ambient air while subjecting them to an external energy radiation of less than 100 kW / m 2 power and imposed by a radiant heating controlled in temperature, makes it possible to obtain the released heat expressed in MJ / m 2 and the peak of heat output expressed in kW / m 2 .
- each sample is shaped into square plates 10 cm square and 3 mm thick.
- Table 3 collects the data collected by the cone-calorimeter analyzes with the samples from Table 2. ⁇ u> Table 3 ⁇ / u> Sample Heat release rate (MJ / kg) Peak of heat released (kW / m 2 ) 1 23 910 2 21 1030 2 bis 19 756 4 23 755 5 22 860 5 bis 23 228 6 37 1360 7 43 1310
- Sample 8 is a composition comprising a biopolymer (Cellulose), a synthetic polymer (EVA) and magnesium hydroxide.
- Samples 9 to 11 respectively correspond to samples 2, 6 and 7 added with a flame retardant filler.
- Samples 12 to 14 correspond to sample 2, supplemented with a flame retardant filler.
- Samples 15 to 17 correspond to the sample 5 bis supplemented with a flame retardant filler.
- Sample 18 corresponds to sample 2 bis added with a flame retardant filler.
- the samples in accordance with the invention have better flame-retarding properties since the heat content released from samples 8, 9 and 12 to 18 according to the invention are much lower than those of samples 10 and 11. for lower or equivalent peak heat values.
- the sample 12 thus obtained makes it possible to obtain a tensile strength of 19 MPa and an elongation at break of 70%.
- the mixture of these two biopolymers advantageously has well-balanced mechanical properties, whose tensile strength is greater than that of the sample 2 and the elongation at break is greater than that of the sample 1.
- compositions 1, 2, 5 and 5 bis of Table 1 are extruded on a metal conductor of 1.03 mm diameter in a layer of approximately 0.50 mm, in order to obtain the respective electrical wires 1, 2, 5 and 5 bis.
- composition 1 extends from 145 ° C. to 200 ° C. under a pressure of 150 Bar, that of composition 2 extends from 100 ° C to 135 ° C under a pressure of 135 Bar, and that of the compositions 5 and 5 bis extends from 120 to 150 ° C under a pressure of 190 bars, these extrusion profiles being well known to man of career.
- the insulation test according to IEC 60502-1 consists in immersing the electric wires in water for at least one hour before said test.
- a DC voltage between 80V and 500V is then applied for a sufficient time (between 1 and 5 min) then the resistance of the ring is measured. This is used to determine the insulation constant.
- Ki values are advantageously greater than those recommended for certain materials, especially for polyvinyl chloride.
- the extrusion of said composition makes it possible to achieve significant layer thicknesses of the order of at least 0.3-0.5 mm, unlike film-forming coatings, and thus makes it possible to obtain optimized insulating properties.
- compositions in question are used in the production of extruded insulating and / or sheathing and / or stuffing materials for energy and / or telecommunication cables.
- composition may furthermore comprise other additives, especially antioxidants, UV stabilizing agents, plasticizing agents, pigmentation agents or coloring agents.
- the plasticizing agents may be added to the composition according to the present invention in order to improve the elongation at break of said composition.
- plasticizer of castor oil, crodamide or triethyl citrate.
- the present invention is not limited to the examples of compositions which have just been described and generally relates to all the cables that can be envisaged from the general indications given in the description of the invention.
