Definitions

  • the subject of the invention is a composite material and its production device.
  • the material according to the invention is based on mineral fibers, in particular glass fibers, obtained by reconstitution of a mat of mineral fibers containing a binder. It is used, for example, as a primitive for obtaining molded parts.
  • natural fibers are used in particular textile fibers which have a fairly large average diameter, greater than 10 microns which is not very favorable from the point of view of the performance of acoustic and thermal insulation.
  • synthetic fibers mineral fibers are more particularly preferred, in particular the so-called insulation fibers such as glass fibers, rock fibers or slag fibers which are finer and are also produced at extremely low costs.
  • Patent application FR 2 608 964 describes, for example, the use of glass fiber mats for obtaining molded parts such as, for example, fittings for automobile parts.
  • the primitives are in this case sections of glass fiber mats obtained by high speed centrifugation of molten glass with a gaseous drawing of the filaments; the fibers being received on a endless conveyor belt closing a hood in which they are sprayed with an organic binder in aqueous solution; the sheet thus obtained being subsequently shaped in an oven where the polymerization of the binder occurs, and then cut to the desired dimensions to form the mat.
  • Fiberizing processes can be used, in particular so-called free centrifugation processes or processes in which the molten material is introduced into the interaction zone of two gas streams at high temperatures and at high speeds.
  • the reception is characterized by an aspiration of the fibers being collected on the endless strip under which a vacuum chamber is provided. Consequently, and even if it is possible to partially remedy it by operating under appropriate fiberizing and suction conditions, the mats or mineral fibers thus obtained always exhibit anisotropy, the fibers preferably being positioned in horizontal planes. This results in an anisotropy of certain physical properties, in particular of the tensile strength, anisotropy which moreover has certain advantages in particular with regard to the insulating power of the felt formed.
  • the insulating layers obtained from such flakes are significantly better than the blown wool layers obtained in the traditional way, but on many points, in particular the thermal conductivity, the difference between the properties of these layers and those of the mat. origin is still very sensitive.
  • the addition of binder can be carried out before the flakes are reunited again, at a temperature and under conditions free from any stress due to the process for preparing the fibers. .
  • the reception of the flakes can be done simply by depositing under gravity, that is to say under conditions which do not give rise to preferential orientation of the fibers and which therefore lead to more isotropic products.
  • patent publication AU-A-75 746/87 teaches a process for obtaining an insulating fibrous product containing a uniformly distributed binder, even if the product is based on fibers which are difficult to impregnate such as vegetable fibers. or animal.
  • This process - which can also be applied to mineral fibers - consists in carding a felt to substantially separate the fibers, then to complete this separation by fluidizing them by entraining them by a gas stream, the binder being sprayed on the fibers separated before that these are not deposited.
  • the subject of the present invention is a composite product based on mineral fibers obtained by reconstitution of a mat or felt in mineral insulation fibers, the thermal performance of which (based on an identical mass of product) is at least equal to 93%. those of the initial felt and comprising a binder which can be activated subsequently, chosen independently of the technique used to obtain said initial felt.
  • the composite product according to the invention is formed of flakes to which a subsequently activatable binder is added, obtained by shredding a felt based on mineral insulating fibers, less than 10% of the flasks comprising a dense nodule whose average diameter is more defined as less than 7 mm and which has a lower degree of impregnation with reactivable binder than the rest of the product.
  • the flakes are produced from a mineral fiber felt which is shredded using a carding machine made up of a single soft bristle brush cleaned by a comb.
  • a carding machine with counter-rotating brushes conforming to FR-2 591 621 produces flakes comprising half of them dense nodules (and it is not possible to remedy this defect by extending the presence time flakes between the brushes because then the fibers are reduced to dust).
  • the composite product according to the invention contains a binder which can be activated subsequently.
  • a time set by the user is understood to be possibly a few seconds, where a polymerization oven is provided immediately downstream of the line or, on the contrary, several days and even several months, the latter case being more particularly found.
  • the duration of this period depends of course on the type of binder used, intermediate storage of the product is only possible with resins whose action does not occur - or extremely slowly - at room temperature. This is the case, for example, of hot-melt or thermosetting resins, added in powder form to the fibers.
  • hot-melt or thermosetting resins examples include phenol-formaldehyde novolac resins, epoxy resins, silicones, polyurethane, polyethylene and polypropylene.
  • the binder In liquid form, the binder is sprayed onto the fibers, either at the time of the carding operation or after it.
  • the addition of the binder is preferably carried out after carding, the binder being suspended in a gas for optimal distribution.
  • the flakes are preferably collected by simple deposit under gravity, without additional suction.
  • the products thus reconstituted are much more isotropic than the standard products obtained directly under the fiber hood, which is more particularly advantageous for the preparation of molded shaped parts which may be subsequently subjected to stresses at fairly high levels, this which is of course not the case when the flakes are used in bulk.
  • the composite product according to the invention is prepared as shown very diagrammatically in FIG. 1.
  • the initial felt 1 which we also call standard felt - or the 2 felts as shown here - is a felt made of mineral fibers.
  • a glass wool felt can be used, for example, the fibers being obtained by a process according to which the molten glass is introduced inside a centrifuge plate rotating at high speed from which it escapes in the form of filaments by a series of orifices made on the wall of the plate, the filaments being drawn in the form of fibers by a gas stream at high speed and high temperature, generated by burners surrounding the plate.
  • the temperature conditions of the glass and the gases, the pressures and the speeds used being for example those defined in European patent EP-91866.
  • the sizing is advantageously sprayed on the fibers before they are collected by a receiving member.
  • This sizing is preferably a 10% aqueous solution of a formo-phenolic resin comprising partly dry 55% by weight of resol resin and a silane acting among other actions as an anti-dust agent.
  • a felt was used whose density is 11 kg / m3, the thermal resistance of 2 m2 ° C / Watt and the specific resistance to the passage of air of 6.4 Rayls / cm (resistance measured perpendicular to the glass fiber deposition plane).
  • the felt conditioned in the roll state is mounted on a reel here not shown.
  • the supply of the carding unit is obtained by means of a cylinder 2 and a counter-cylinder 3 ensuring the advancement of the product.
  • the felt 1 is simply compressed between the cylinders 2, 3, without cutting, which simplifies the device for these operations.
  • these two cylinders also maintain the felt by retaining it somewhat.
  • the carding unit 4, surrounded by a casing, is advantageously constituted by a single brush 5.
  • This brush has an outside diameter of for example 300 mm. It is provided with 6 fine bristles, mounted at a sufficient free height (within 45 mm) to allow them a certain flexibility. These bristles have for example a diameter of the order of 0.5 mm and are preferably wavy. According to the invention, they are preferably made of metal, the best results have been obtained with hardened steel. The choice of metal may seem surprising given that it is known that bristles made of synthetic materials, for example polyamide, are more resistant to attack by abrasion from glass.
  • such a brush with fine metal bristles makes it possible to increase the number of bristles and to eliminate the counter-brush which has the disadvantage of prolonging the processing time of the felt made of mineral fibers and therefore accentuates its degradation.
  • the density of bristles must be high enough to allow complete shredding and over a small portion of the brush, but without however reaching a value such that it prohibits a separate action of each bristle.
  • a spacing of the bristles at the periphery of between 2 and 5 mm is satisfactory, better results having been obtained with approximately 1500 bristles, ie 1 bristle every 3.5 mm for a brush with a diameter of 300 mm.
  • the speed of rotation of the brush is for example close to 1000 revolutions per minute when the unit is fed by a felt of 11 kg / m3.
  • a simple comb 7 is used, consisting of points mounted on a plate 8, preferably very thin and very pointed. These points are, for example, metal needles less than 0.2 mm in diameter at the point which penetrate into the brush at a depth of for example 2 mm, this depth being able to vary thanks to the position adjustment mechanism 9.
  • the flakes are collected by gravity deposit in a closed enclosure 10, without transport by pneumatic means.
  • This pneumatic transport has the disadvantage during the extraction of air of favoring a preferential orientation of the flakes parallel to the direction of the carrier gas and moreover, it appreciably increases the cost price of the product.
  • the closed receiving chamber 10 is preferably made entirely of plastic.
  • the other aspect of the invention is the addition of a binder; after dosing (by pumps 11, 12) the binder is led through a pipe 13 to the fibers.
  • a binder in liquid form will rather be sprayed at a level located after the carding unit, this in order to avoid if possible fouling of the latter against a binder in powder form, with "wetting" power. less, will be sent to him on the flakes at the carding unit.
  • this is only a general trend, the problem arising more precisely for each binder used.
  • the extreme opening of the flakes obtained according to the invention allows, if necessary, a very homogeneous distribution of the binder even after carding.
  • the fibers are deposited on a receiving mat 14 closing the carding hood 10. As shown in FIG. 1, this hood 10 completely closes the system which leads to yields of materials close to 100%.
  • the mattress is brought back to the desired thickness by a calendering machine 15 then the product is optionally led into an enclosure 16 in which a circulation of hot air is established ensuring the setting of the binder (for example in a melting furnace of the binder in the case of a hot-melt product).
  • a circulation of hot air is established ensuring the setting of the binder (for example in a melting furnace of the binder in the case of a hot-melt product).
  • it is of course carried out the various cutting operations 17 necessary before obtaining the finished product.
  • Another particularly interesting application of the method according to the invention is the production of molding primitives and in this case, the product is directly packaged after calendering, the setting of the binder taking place subsequently during the molding operation.
  • Products have been produced with extremely diverse amounts of binder. Tests have been carried out, for example, with a very low percentage of binder of between 10 and 15%, for a heat-activatable binder intended for a primitive for products molded using a hot press. Conversely, composite products have also been prepared comprising more than 70% of a mineral binder which can be activated by the addition of water.
  • the measured values for products a, c and d are practically identical.
  • the method according to the invention therefore makes it possible to produce end products very comparable to those of the art but which can be produced according to a production in two deferred stages, thus making the molding step independent of the step of fiber preparation.
  • Another aspect of the device according to the invention is that of recycling fibers. Indeed, it is known to prepare insulating products from fiber glass fiber felt waste.
  • the so-called textile fibers are therefore recovered by carding a felt using a carding machine traditionally used by the textile industry. Felts based on so-called insulating fibers such as those envisaged by the present invention do not not suitable because the carding machine transforms these more fragile fibers into dust.
  • With a carding machine according to the invention it is possible to replace part of the textile fibers with insulation fibers.
  • a reconstituted felt weighing 1.2 kg / m3 was thus produced without particular difficulty, for a density of 25 kg / m3, made up of 12% "flakes" according to the invention, of 74% fibers.
  • textile glass and 14% of a phenolic binder The proportion of mineral insulation fibers can possibly be increased to 20 or 25%, which is particularly advantageous when the available quantity of textile fiber waste is insufficient to cover the demand for reconstituted insulating products.
  • the first of these curves ( Figure 3) is a representation of the Lambda thermal conductivity measured in mW / m. ° K, as a function of the density of the prepared product (fibers and binders). This curve relates directly to the insulation capacity of a product, in fact the thermal conductivity is defined as equal to the ratio of the thickness of the product to its thermal resistance.
  • Curve A is the characteristic curve of a standard product obtained by the centrifugal process with gaseous stretching described above, the fineness of the fibers being characterized by a micronaire of 3 for 5 g.
  • the micronaire F is defined in a standardized way as the flow rate of a gaseous current measured after this gaseous current emitted under well-fixed pressure conditions has passed through a very compressed sample of 5 g of fibers. Note that the micronaire gives an indication of the braking of the gas stream by the glass fibers and is therefore characteristic of the fineness of the fibers. Such a micronaire of 3 to 5 g is characteristic of very fine glass fibers.
  • Curve B is that obtained with reconstituted products according to the invention, while curves C and D are respectively obtained for reconstituted products obtained in accordance with the teaching of FR 2,591,621 and for blown glass wool obtained in a conventional manner.
  • curves A and B are practically parallel and that consequently, the difference between the initial product (according to curve A) and the product reconstituted according to the invention is for the entire density range considered between 5 and 7%.
  • the composite product according to the invention can very easily replace the standard product, without a deterioration in the qualities being practically observable; we can especially produce very light products, typically 10 kg / m3 or less while blown fiber products always have a density greater than 15 kg / m3 (and in this case with very low insulating power compared to standard felts) , and that the lower limit is close to 12-13 kg / m3 for products according to FR 2 591 621.
  • the parallel specific resistance is much lower than the perpendicular specific resistance.
  • the curve 24 of the parallel specific resistance is practically coincident with the curve 22 of the standard product; on the other hand, the perpendicular specific resistance (curve 23) is a little lower. This explains the weakening of the insulation performance of the product (see thermal conductivity curve) but also shows that the anisotropy of the product has decreased.
  • Curve 31 corresponds to a standard product, always in the sense defined above, whose density is 45 kg / m3. Practically vertical at the start - which corresponds to a significant increase in the relative deformation even for a weak stress, the curve bends slightly for more important stresses but remains permanently concave. In addition, we see that a rate of 50% relative deformation is reached for a stress of 18 kg / m2.
  • the curve 32 is relatively flat, in other words the increase in the relative deformation is slower than that of the stress exerted.
  • This in fact corresponds to the presence of vertically arranged fibers which have the possibility of bending while in the horizontal plane the relative deformation is directly the result of the deformation of the fibers themselves under the effect of the stresses.
  • the curve of the relative strain becomes identical to that of the standard product, but starting from a non-zero initial value. It is indeed noted that for a given relative deformation, the stress to be exerted is approximately 12 kN / m3 higher with a reconstituted product.
