Abstract
Description
- 1 La présente invention concerne un procédé de production de mélange-- 1 The present invention relates to a process for producing a mixture
maîtres utilisés par les plasturgistes. Le procédé de production traditionnel est l'extrusion de mélanges sous forme de granulés ou " lentilles ". Ceux-ci sont constitués de matière plastique et d'une ou plusieurs poudres homogénéisées à chaud dans une extrudeuse. Les pourcentages de ces composants varient suivant les utilisations. Les inconvénients de ce procédé sont: - la présence de matière plastique dans le mélange-maître, - un pourcentage variable et inférieur à 100 % de produit actif dans le mélange-maître, - une température de transformation égale à la température de fusion de ou des 10 matières plastiques utilisées, - l'impossibilité de créer des mélange-maîtres biodégradables à cause de la matière masters used by plastics manufacturers. The traditional production process is the extrusion of mixtures in the form of granules or "lenses". These consist of plastic and one or more powders homogenized hot in an extruder. The percentages of these components vary according to the uses. The disadvantages of this process are: - the presence of plastic in the masterbatch, - a variable percentage of less than 100% of active product in the masterbatch, - a transformation temperature equal to the melting point of of the 10 plastic materials used, - the impossibility of creating biodegradable masterbatches because of the material
plastique rentrant dans la composition des mélanges. plastic used in the composition of mixtures.
Le procédé selon l'invention concernée permet de remédier à ces inconvénients. En effet, le procédé retenu consiste à comprimer à chaud ou à froid des poudres afin d'obtenir des 15 " pastilles " ou " comprimés " dont les dimensions peuvent être variables. Cette compression pourra être obtenue dans une machine à comprimer du type rotatif ou alternatif. The method according to the invention concerned overcomes these drawbacks. In fact, the method chosen consists in compressing powders hot or cold in order to obtain "pellets" or "tablets" the dimensions of which can be variable. This compression can be obtained in a rotary or alternative type compression machine.
Les avantages de ce procédé sont les suivants: - un pourcentage de 100 % de produits actifs contenus dans les mélange-maîtres, - une utilisation de ces mélange-maîtres à des températures plus basses qu'avec 20 des mélange-maîtres traditionnels, d'o économie d'énergie, - la possibilité de créer des mélange-maîtres biodégradables et/ou photodégradables du fait de l'absence de matière non biodégradable dans le mélange-maître (matière plastique). The advantages of this process are as follows: - a percentage of 100% of active products contained in the masterbatches, - a use of these masterbatches at lower temperatures than with traditional masterbatches, o energy saving, - the possibility of creating biodegradable and / or photodegradable masterbatches due to the absence of non-biodegradable material in the masterbatch (plastic).
Ce procédé de production de mélange-maîtres sera plus particulièrement adapté à la 25 production de mélange-maîtres biodégradables et/ou photodégradables et dont la liste non limitative fait partie du présent brevet et est ci-dessous mentionnée. This method of producing masterbatches will be more particularly suitable for the production of biodegradable and / or photodegradable masterbatches, the non-limiting list of which is part of this patent and is mentioned below.
Les mélanges biodégradables ainsi " comprimés " avec les poudres cidessous nommées et qui font également l'objet du présent brevet pourront servir à produire des articles tels que couverts à usage unique, rasoirs, cintres et seringues jetables, stylos, 30 crayons, barquettes, golf-tee, bougeoirs, cartouches, bourres et obturateurs de chasse, tubes pour artificiers, sacs divers (emballage, à déchets, hypermarchés,...), films et housses divers (emballage, funéraires, agricoles,...), bouchons, bouteilles, flacons, bidons, pots d'horticulture, agrafes pour vignerons, filets pour la pêche, coton-tiges, etc... et des articles rencontrés dans des domaines d'application tels que la santé, l'hygiène, l'horticulture, 35 l'emballage, la viticulture, la pêche, la chasse, la pyrotechnie, le bouchage, le surbouchage, l'agriculture, etc,... The biodegradable mixtures thus "compressed" with the powders below named and which are also the subject of this patent may be used to produce articles such as disposable cutlery, razors, hangers and disposable syringes, pens, 30 pencils, trays, golf -tee, candlesticks, cartridges, flasks and shutters, fireworks tubes, various bags (packaging, waste, hypermarkets, ...), various films and covers (packaging, funeral, agricultural, ...), caps, bottles, flasks, cans, horticultural pots, staples for winegrowers, fishing nets, cotton swabs, etc ... and articles encountered in fields of application such as health, hygiene, horticulture , 35 packaging, viticulture, fishing, hunting, pyrotechnics, capping, overcapping, agriculture, etc, ...
