Definitions
- the invention relates to a process for manufacturing sheets or plates of thermoformable plastic, which can be used as thermocycling reinforcement material or for the preparation of orthopedic reinforcements.
- FR-A-2 392 810 describes a product of this type consisting of a synthetic material (binder) reinforced with an inert filling material.
- EP-A-0 183 912 describes a material of the same type in which the filling material consists entirely or at least superficially of plastic material.
- the starting substances, binder and filling material consist of powders having comparable particle sizes and preferably from 50 to 500 ⁇ m, and in particular from 100 to 400 ⁇ m.
- Obtaining and handling powders having such granul ⁇ meries can pose economic problems as well as the usual disadvantages of powders, namely static electricity and irregularity of the physico-chemical properties of the products obtained.
- FR-A-2 559 503 describes stiffening materials for leather, consisting of at least one layer of synthetic material obtained by sintering a mixture of two polymer components of different melting point. The product obtained is not fusible.
- the invention solves the problem by providing sheets and / or thermoformable sheets from the temperature of 80 * C-90 * G and fusible from this same temperature, usable as fusible reinforcing material, obtained by a process characterized in that
- the mixture is extruded under low shear conditions are low temperatures 100'G 140 ° C, giving the mixture a pasty consistency sufficient to form a homogeneous mixture of melted polymers,
- the product is laminated or calendered under high pressure at a temperature of the order of 100 "C to reduce the thickness and cooled to an internal temperature of 30 "C before the end of rolling or calendering.
- polyesters As a polymer of low melting point, can be employed polyesters, polyurethanes, ethylene / acetate or ethylene / acrylic m ⁇ nomêre having "a 50 melting point 90 ° C. These polymers are used in the form of granules of 2 to 3 mm such as those commercially available. Other polymers can also be used, the main thing being that they have a tackiness at low temperature and under low pressure.
- melting or softening may be mentioned by way of example poly (vinyl chloride), polycarbonates, polyethylenes, ABS (acrylonitrile / butadiene / styrene ⁇ > or any other compatible polymer wholly or partially with the lowest point of polymers of fusion mentioned above, in the form of granules as commercially available (granules of 2 to 3 mm ) or in the form of powders having a particle size preferably of 500 to 1000 ⁇ m. they can be obtained from powders used to recover plastics.
- the additives which may be used are the usual additives in this type of product, for example mineral fillers with small particle sizes, plasticizers, dyes, etc. It is generally possible to use up to 20 parts by weight of these usual additives per 100 parts by weight of the polymer mixture.
- the mixture obtained is brought to temperatures of 100 ° to 140 ° C. in a short single-screw or twin-screw extruder with a low compression and / or shear rate.
- Such an extruder * makes it possible to avoid excessive shearing of the polymers during melting or softening. in this way and under the effect of heat, the mixture takes on a pasty consistency, insufficient to transform the good mixture of granules into a homogeneous mixture of molten polymers.
- the extrusion is carried out without significant mechanical effort and at a temperature not exceeding 140 ° C., which in fact corresponds to imperfect extrusion conditions. In this way, a product is obtained which retains the adhesion properties of the type of polymers with a low melting point and acquires the thermoforming and rigidity properties of the mixture of the two types of associated polymers in a partial alloy.
- the product obtained has a surface irregularity (rough surface) and is poorly bonded; it obviously contains grains of the type of polymer (s) with a high melting or softening point, which shows that the starting granules have not undergone a complete melting,
- the strip thus obtained is then calendered or laminated with or without textile support .
- a calender with three rollers will be used, the product being calender between two rollers under high pressure at a temperature of approximately 100 ° C. in order to reduce the thickness and then being cooled on the third roller has a temperature below 30 ° C.
- calendering can be carried out with a belt press with a heating zone and a cooling zone allowing the hot rolling of the product and the cooling of the laminated strip obtained.
- This calendering or rolling operation makes it possible to obtain the desired thickness of the final product, because the imperfect extrusion conditions only allow a relatively thick continuous strip, of the order of 1 to 3 mm, to be obtained. finer dies not allowing the pasty mixture to pass.
- the calendering or rolling operation under high pressure makes it possible to reduce its thickness.
- the product leaving this treatment is densified and well bonded, has a smooth surface and has a good tackiness on the surface, because the operation seems to have the consequence of causing the most fluid product to migrate to the surface, i.e. -to say the polymer of low melting point.
- the product obtained can then undergo conventional operations, such as laminating in a calendered fabric or other textile support, winding on a spool or cutting into sheets or plates.
- the starting materials to be mixed namely polymer of low melting point, polymer of highest melting point and usual additives, are introduced into a mixing metering device 1, for example a mixing metering unit of the weight type with several tanks.
- the mixture obtained is transported via a pipe 2 into the feed hopper 3 of an extruder 4.
- This extruder comprises a relatively short screw 5 expelling the pasty mixture through a die 6.
- the film leaving the die 6, rough and poorly bonded, of a thickness of 1.2 mm for example, is brought to a calender 7, for example to three cylinders, into which is introduced a first textile support 9, coming from a supply reel 8.
- the product leaving the calender 7 is smooth, densified and well bonded, and has a thickness, for example, of 1.0mm + 0.05mm. It is carried by a band conveyor to a second calender 11 under low pressure, supplied with a second textile support 12 by a supply coil 13 Before entering the calender 11, the transported product is heated on the surface to a temperature of 80-100 "C, for example by an infrared device 14.
- the product obtained is cut at the cutting station 15 and packaged on a conditioning table 16. It is understood that the use of the second calender 11 is optional and that one can be satisfied with '' a product with a single textile support, or even without a textile support.
- the first textile support can be introduced as above before calendering under high pressure, or can be introduced after this first calendering, with the second textile support.
- the cutting station and the conditioning table can be replaced by a winding device on a mandrel.
- the first calender 7 can also be replaced by a belt press of the type described above. In such a press, the product introduced is strongly compressed and the thickness of the product leaving the extruder is significantly reduced as in the case of calendering. .
- polymer (s) is intended to mean either a polymer or a mixture of polymers, in the two cases with optionally the conventional processing aids, and in particular the formulations as placed on the market.
