Abstract
Description
L'invention concerne un matériau thermoplastique de modelage. The invention relates to a thermoplastic modeling material.
Le matériau de l'invention est caractérisé en ce qu'il comporte en mélange du polycaprolactone et une charge minérale de carbonate de calcium en poudre fine dans la proportion de 40 à 100 g de carbonate de calcium pour 100 g de polycaprolactone. The material of the invention is characterized in that it comprises a mixture of polycaprolactone and an inorganic filler of calcium carbonate in fine powder in the proportion of 40 to 100 g of calcium carbonate per 100 g of polycaprolactone.
Selon une autre caractéristique de l'invention, le mélange de polycaprolactone et de carbonate de calcium comprend un copolymère dans la proportion de l'ordre de 5 W en poids. According to another characteristic of the invention, the mixture of polycaprolactone and calcium carbonate comprises a copolymer in the proportion of the order of 5 W by weight.
Selon une autre caractéristique de l'invention, le mélange de polycaprolactone et le carbonate de calcium comprend de la poudre de titane dans la proportion de l'ordre de 1 % en poids. According to another characteristic of the invention, the mixture of polycaprolactone and calcium carbonate comprises titanium powder in the proportion of the order of 1% by weight.
L'invention concerne également un procédé pour l'obtention de ce produit, ce procédé étant caractérisé en ce que le mélange des composants est réalisé à une température de l'ordre de 1500. The invention also relates to a process for obtaining this product, this process being characterized in that the mixing of the components is carried out at a temperature of the order of 1500.
La présente invention a en conséquence pour but la réalisation d'un matériau thermoplastique de modelage d'un coût réduit et qui à température ambiante est d'une très grande dureté et d'une grande résistance aux chocs. Ce produit présente en outre la particularité d'être à l'état plastique pour une température supérieure et sur une plage de températures relativement importante tout en réduisant la variation de cette plasticité à l'intérieur de cette plage. The present invention therefore aims to achieve a thermoplastic modeling material of a reduced cost and which at room temperature is of very high hardness and great impact resistance. This product also has the particularity of being in the plastic state for a higher temperature and over a relatively large temperature range while reducing the variation of this plasticity within this range.
On aboutit ainsi à un produit thermoplastique de modelage dont la consistance à l'état pâteux lui permet d'être modelé et de conserver la forme qu'on lui donne pour cette plage de températures étendue. Ce résultat est également obtenu par le fait que la vitesse de refroidissement du produit est ralentie tandis que le passage de l'état pâteux à l'état solide s'effectue sans rétreint de la matière, ce qui est particulièrement important lorsque l'on désire réaliser des modelages, des surmoulages ou des contre-moulages précis. This results in a thermoplastic modeling product, the consistency of which in the pasty state allows it to be molded and to retain the shape which it is given for this extended temperature range. This result is also obtained by the fact that the speed of cooling of the product is slowed down while the transition from the pasty state to the solid state takes place without shrinking of the material, which is particularly important when it is desired perform precise modeling, overmolding or countermolding.
Le produit de l'invention présente également la particularité de pouvoir aisément être usiné, percé, meulé, etc. lorsqu'il est à la température ambiante, tandis que du fait de sa grande dureté et de sa résistance importante aux chocs, ces possibilités de mises en oeuvre sont considérablement augmentées. The product of the invention also has the particularity of being able to be easily machined, drilled, ground, etc. when it is at room temperature, while due to its high hardness and its high impact resistance, these possibilities of implementation are considerably increased.
Les avantages de ce matériau résultent également du fait qu'il est un excellent isolant électrique et qu'il n'est pas collant, sauf sur certaines matières plastiques et pour des températures élevées. The advantages of this material also result from the fact that it is an excellent electrical insulator and that it is not sticky, except on certain plastics and at high temperatures.
Ce matériau est obtenu en réalisant le mélange d'un polycaprolactone avec du carbonate de calcium en poudre très fine, ce mélange étant réalisé alors que le polycaprolactone dont la température de fusion est de 650 est porté à une température beaucoup plus importante et de l'ordre de 1500. This material is obtained by mixing a polycaprolactone with very fine powdered calcium carbonate, this mixture being produced while the polycaprolactone, the melting temperature of which is 650, is brought to a much higher temperature and order of 1500.
A cette température, il est alors possible de réaliser un mélange intime et homogène du carbonate de calcium et du polycaprolactone comme cela est nécessaire pour aboutir à une pâte à modeler. At this temperature, it is then possible to produce an intimate and homogeneous mixture of calcium carbonate and polycaprolactone as is necessary to result in a modeling clay.
Ce mélange sera de préférence réalisé dans une machine d'extrusion à vis sans fin, cette machine étant pourvue d'une buse produisant un fil de matériau qui est ensuite sectionné pour obtenir des granulés dont la longueur est sensiblement de l'ordre du diamètre du fil, diamètre qui pourra luimême être de l'ordre de 2 à 8 mm. This mixing will preferably be carried out in a worm extrusion machine, this machine being provided with a nozzle producing a wire of material which is then sectioned to obtain granules whose length is substantially of the order of the diameter of the wire, diameter which may itself be of the order of 2 to 8 mm.
Les granulés obtenus pourront alors être aisément amenés à l'état pâteux en les plongeant dans de l'eau bouillante de façon à obtenir l'amalgame de ces granulés sous la forme d'une pâte malléable mais qui conserve la forme qu'on lui donne. The granules obtained can then be easily brought to a pasty state by immersing them in boiling water so as to obtain the amalgam of these granules in the form of a malleable paste but which retains the shape which it is given. .
Les proportions du carbonate de calcium et de polycaprolactone à mettre en oeuvre se situeront entre 40 et 100 g de carbonate de calcium pour 100 g de polycaprolactone et de préférence de l'ordre de 80 g de carbonate de calcium. The proportions of calcium carbonate and polycaprolactone to be used will be between 40 and 100 g of calcium carbonate per 100 g of polycaprolactone and preferably of the order of 80 g of calcium carbonate.
L'amélioration de la résistance aux chocs de cette pâte à modeler sera encore augmentée en incorporant un copolymère au mélange de polycaprolactone et de carbonate de calcium alors qu'ils sont portés à leur température de mélange. The improvement in the impact resistance of this plasticine will be further increased by incorporating a copolymer into the mixture of polycaprolactone and calcium carbonate while they are brought to their mixing temperature.
La quantité de copolymère introduite pourra être de l'ordre de 10 g en poids de copolymère pour 100 g de polycaprolactone. The amount of copolymer introduced may be of the order of 10 g by weight of copolymer per 100 g of polycaprolactone.
Dans le but de donner à la pâte une couleur de base blanche, le mélange global comportera du titane dans la proportion de 1 W en poids environ. In order to give the dough a white base color, the overall mixture will include titanium in the proportion of about 1 W by weight.
Cette couleur blanche de la pâte lui permet alors d'être mélangée avec des produits colorants sans que la couleur de ce colorant mélangée à la pâte ne soit dénaturée. This white color of the dough then allows it to be mixed with coloring products without the color of this dye mixed with the dough being denatured.
