Definitions
- Part made of thermoplastic material loaded with fruit stone flour and process for obtaining such a part.
- the present invention relates to the field of parts made of synthetic materials and their production, and relates to a part made of thermoplastic material, as well as its manufacturing process.
- Thermoplastics have been trending for many years, due to their ease of transformation, the multiple possibilities of configuration, conformation, coloring, shaping and surface states that they offer, their stability and conservation in the time and their resistance to deformation and impact, to systematically replace other materials in many fields of industrial and domestic capital goods, and in particular natural materials such as wood.
- the parts and articles thus obtained do not have good dimensional stability in the event of variation in the surrounding humidity, nor good resistance to putrefaction under the action of humidity and atmospheric agents, and are sensitive to freezing. , which limit their application in an outdoor environment, unless subjecting said flour or sawdust to a hydrophobic and waterproofing chemical pretreatment, which again takes away its cachet of natural product.
- the present invention aims in particular to overcome the aforementioned drawbacks.
- the inventors have found, unexpectedly and surprisingly, that the use of fruit kernel flour makes it possible to meet the abovementioned expectations while avoiding most of the limitations of existing solutions.
- the object of the present invention consists of a part (or article) of thermoplastic material (s), characterized in that it comprises in its mass particles of flour of fruit kernels, mixed as that charge to said plastic material (s) before the manufacture or the formation of said part, as well as to a process for manufacturing such a part or of such an article.
- composition of thermoplastic material (s) forming the base material of the part may consist either of a single thermoplastic material, or of a mixture of several compatible or made compatible thermoplastic materials.
- the flour is essentially obtained from the lignified endocarps or hulls of the nuclei and the latter advantageously come from fruits of oleaginous trees, preferably from olives.
- the average size of the flour particles is between 50 ⁇ m and 500 ⁇ m, preferably between 70 ⁇ m and 120 ⁇ m, and the flour content is between approximately 5% and approximately 50 %, advantageously between 10% and 20% o, and preferably around 15%, by weight of dry flour (humidity below 10%, preferably below 5%) in the final composition of material (s) thermoplastic (s) used for the manufacture of said part.
- the particles obtained by fine grinding are dried and, if necessary, tinted or treated by coloring before they are mixed with the thermoplastic materials.
- the present invention also relates to a method for manufacturing parts made of thermoplastic material (s), characterized in that it consists in forming a homogeneous mixture comprising, as main component, a composition of thermoplastic material (s) ( s) and as a load of fruit stone flour, then transforming said mixture into plasticized form, to form parts or articles as mentioned above.
- Said method may more specifically consist in providing flour of dried fruit kernels, a composition of thermoplastic material (s) and one or more additive (s) for stabilization, lubrication, for increasing impact resistance. and / or to facilitate processing, to mix and heat these ingredients to a temperature approximately 5 to 20 ° C (preferably 10 to 15 ° C) above the normal heating temperature of said composition of material (s) thermoplastic (s), for an identical transformation, in the absence of filler in the form of flour, then to allow the resulting mixture to cool and, optionally, to allow it to stand for a predetermined period, said mixture retaining a pulverulent constitution during the all of the aforementioned operations, and, finally, transforming said mixture into one or more parts as described above by a suitable transformation operation, if necessary, after granulating it.
- a suitable transformation operation if necessary, after granulating it.
- thermoplastic material (s) / flour and if necessary its heating, may be carried out on a separate station or on a station integrated into the machine operating the transformation of the resulting mixture.
- provision may be made to tint or impregnate coloring substances with the flour kernels of fruit cores, preferably obtained from the shells of olive cores, before they are mixed with the composition of thermoplastic material (s), and to vary the particle size of said particles (if necessary by mixing flours of different particle sizes).
- thermoplastic being preferably chosen from the group formed by vinyl, olefinic and styrenic polymers, and compatible blends of these polymers.
- the production of an extruded piece of rigid PVC incorporating flour of olive kernels is described below.
- composition of the mixture of materials and substances used for the manufacture of the aforementioned part is indicated in the table below in terms of weight parts:
- composition of the mixture / Formulation (rigid PVC type)
- an adequate coloring substance is added.
- a mixer of the so-called rapid mixer type is used, which is equipped with a heating tank and a cooling tank.
- the heating temperature is brought to about 130 ° C to 160 ° C, preferably to about 150 ° C, in the heating tank.
- the mixture is passed through the cooling tank and allowed to cool to a temperature of about
- the types of extruders best suited for this transformation are the twin screw extruders, the precise choice of the extruder, as for its capacity and its performance of extrusion volume, being linked to the metric weight of the profile to obtain.
- the extrusion line does not differ, in terms of structure and operation, from the usual standard known to those skilled in the art.
- the implementation in the extraction process of mixtures loaded with flour from oilseed kernels, and in particular from olives, is similar in terms of the settings of the extraction line (in particular in terms of temperatures, pressure and suction), to the settings of such a line for the extrusion of an uncharged rigid PVC.
- thermoplastic material consists of another polymer or mixture of polymers
- said settings will be substantially equivalent to those necessary for the extrusion of such uncharged polymers (such as for example: PVC / Polypropylene / Acrylonitrile- Butadiene- Styrene) .
- thermoplastic materials in particular PVC or PP (Polypropylene), which stand out from comparable parts or articles existing by a lower cost price.
- PVC or PP Polypropylene
- the integration of the aforementioned type of flour into the thermoplastic materials is carried out easily and in a homogeneous manner, without requiring specific additional operations.
- fruit stone flour especially olive flour
- fungi bacterial flora
- the particles of kernel flour have a hardness and a material density significantly higher than those of traditional wood flour.
