Description

Pièce de conteneur de déchets réalisée en pneumatique recyclé Waste container part made of recycled tire
L'invention concerne le domaine technique des conteneurs de déchets. Ces conteneurs de déchets peuvent être par exemple des bacs roulants destinés à la collecte des déchets ménagers, des conteneurs enterrés ou semi-enterrés.The invention relates to the technical field of waste containers. These waste containers may be for example rolling bins for the collection of household waste, buried or semi-buried containers.
De plus en plus, de tels conteneurs de déchets sont réalisés partiellement en matière plastique. En particulier, certaines pièces, comme par exemple les bandages de roues ou les butées d'amortissement du couvercle d'un conteneur de déchets, sont réalisées en caoutchouc.More and more, such waste containers are partially made of plastic. In particular, certain parts, such as wheel tires or damping stops of the lid of a waste container, are made of rubber.
Les différents matériaux utilisés pour la fabrication de ces pièces de conteneurs de déchets présentent de bonnes qualités mécaniques mais leurs coûts sont parfois élevés.The different materials used for the manufacture of these pieces of waste containers have good mechanical properties but their costs are sometimes high.
Aussi, l'invention a notamment pour but de proposer des pièces de conteneur de déchets réalisées en un matériau plus économique. A cet effet, l'invention a pour objet une pièce de conteneur de déchets, réalisée en un mélange de résidus de broyage de pneumatiques usagés et de matière thermoplastique.Also, one object of the invention is to provide waste container parts made of a more economical material. For this purpose, the subject of the invention is a piece of waste container made of a mixture of grinding residues of used tires and of thermoplastic material.
Les résidus de broyage de pneumatiques usagés, parfois appelés poudrette lorsque la dimension de leurs particules est inférieure à 20 millimètres, constituent un matériau relativement bon marché. Il est donc particulièrement intéressant d'utiliser ce matériau pour la conception de pièces de conteneurs de déchets.Used tire grinding residues, sometimes referred to as crumb when the size of their particles is less than 20 millimeters, is a relatively cheap material. It is therefore particularly interesting to use this material for the design of waste container parts.
Toutefois, la poudrette de pneumatiques recyclés est un matériau qui, une fois moulé, par exemple par injection, ne présente pas une cohésion suffisamment importante pour pouvoir former des pièces de conteneurs de déchets résistantes. En particulier, il n'est pas recommandé de fabriquer des bandages de roues de conteneurs de déchets entièrement en poudrette de pneumatiques recyclés du fait d'un manque de cohésion mécanique.However, the crumb of recycled tires is a material which, once molded, for example by injection, does not have sufficient cohesion to be able to form parts of resistant waste containers. In particular, it is not recommended to manufacture wheel tires of waste containers made entirely of recycled tire crumb because of a lack of mechanical cohesion.
Aussi, l'invention propose de mélanger ces résidus de broyage de pneumatiques usagés avec de la matière thermoplastique. La matière thermoplastique a un effet de liant des particules de pneumatiques entre elles et permet d'apporter de la cohésion au mélange.Also, the invention proposes to mix these waste grinding residues of used tires with thermoplastic material. The thermoplastic material has a binder effect of the tire particles together and provides cohesion to the mixture.
Ainsi, grâce à l'invention, il est possible de fabriquer des pièces de conteneurs de déchets dont la matière principale est issue du recyclage de pneumatiques usagés.Thus, thanks to the invention, it is possible to manufacture pieces of waste containers whose main material is derived from the recycling of used tires.
En fonction du type de pièce que l'on souhaite fabriquer, on déterminera les quantités relatives de matière thermoplastique et de résidus de broyage dans le mélange.Depending on the type of part that is to be manufactured, the relative amounts of thermoplastic and grinding residues in the mixture will be determined.
Plus la quantité de matière thermoplastique est importante, plus le matériau est résistant. Toutefois, des impératifs économiques sont également à considérer lors du mélange des matériaux puisque le prix de revient de la matière thermoplastique peut atteindre dix fois celui des résidus de broyage de pneumatiques.The larger the amount of thermoplastic material, the stronger the material. However, economic requirements are also to be considered when mixing materials since the cost price of the thermoplastic material can reach ten times that of tire grinding residues.
Ce type de matériau est particulièrement bien adapté à un usage en tant que pièce de conteneur de déchets car il s'agit d'une application dans lequel les caractéristiques techniques et mécaniques priment sur les caractéristiques esthétiques. En particulier, pour la réalisation d'un bandage de roue ou d'une butée d'amortissement d'un couvercle de conteneur, les caractéristiques esthétiques ne sont pas primordiales contrairement aux capacités mécaniques d'amortissement et de résistance à l'usure. Une pièce de conteneur de déchets selon l'invention peut en outre comprendre l'une ou plusieurs des caractéristiques suivantes.This type of material is particularly well suited for use as a piece of waste container because it is an application in which the technical and mechanical characteristics take precedence over the aesthetic characteristics. In particular, for the realization of a wheel bandage or a damping abutment of a container lid, the aesthetic characteristics are not essential in contrast to mechanical damping and wear resistance. A waste container part according to the invention may further comprise one or more of the following features.
La matière thermoplastique est un polyéthylène. Le polyéthylène est un matériau qui donne de très bons résultats lorsqu'il est mélangé avec des résidus de broyage de pneumatiques. - La quantité de matière thermoplastique est comprise entre 1 % et 60 % en masse du mélange. En fonction du type de pièce à fabriquer, on peut déterminer la quantité relative de matière thermoplastique à mélanger. En particulier, si l'on souhaite obtenir une pièce très résistante mécaniquement, on ajoutera une quantité supérieure de thermoplastique. Si l'on souhaite au contraire une pièce dont les qualités d'absorption acoustique sont grandes, on utilisera une plus faible quantité de matière thermoplastique.The thermoplastic material is a polyethylene. Polyethylene is a material that gives very good results when mixed with tire grinding residues. - The amount of thermoplastic material is between 1% and 60% by weight of the mixture. Depending on the type of part to be manufactured, it is possible to determine the relative amount of thermoplastic material to be mixed. In particular, if it is desired to obtain a very mechanically resistant part, a greater quantity of thermoplastic will be added. If, on the contrary, a part is desired whose acoustic absorption qualities are great, a smaller quantity of thermoplastic material will be used.
La quantité de matière thermoplastique est comprise entre 1% et 7% en masse du mélange. Généralement, la matière thermoplastique est utilisée en quantité majoritaire et les résidus de pneumatique en quantité minoritaire sous forme de charge. Il a été constaté que, contrairement aux préjugés de l'état de la technique, il est possible d'utiliser une quantité très faible de thermoplastique comprise entre 1 % et 7% en masse pour apporter de la cohésion aux résidus de pneumatique et pour fabriquer une pièce dont les qualités mécaniques sont correctes. Même avec une quantité aussi faible que 1 % de matière thermoplastique, celle-ci forme un maillage autour et au sein des résidus de pneumatiques de sorte que, une fois que le maillage a refroidi, il forme un liant des résidus entre eux et empêche leur désolidarisation.The amount of thermoplastic material is between 1% and 7% by weight of the mixture. Generally, the thermoplastic material is used in a majority amount and the tire residues in a minor amount in the form of a filler. It has been found that, contrary to the prejudices of the state of the art, it is possible to use a very small amount of thermoplastic of between 1% and 7% by weight to bring cohesion to tire residues and to manufacture a piece whose mechanical qualities are correct. Even with as little as 1% of thermoplastic material, it forms a mesh around and within the tire residues so that, once the mesh has cooled, it forms a binder of the residues between them and prevents their formation. separation.
Lorsque la quantité de résidus de pneumatiques est très élevée, l'aspect et l'état de surface de la pièce de conteneur obtenue ne sont pas très esthétiques. Toutefois, on peut utiliser un tel mélange comprenant une très faible quantité de matière thermoplastique pour fabriquer des pièces qui sont masquées ou peu visibles et dont les qualités fonctionnelles et mécaniques sont plus importantes que leurs qualités esthétiques. Par exemple, cette invention peut être appliquée pour la fabrication de bandages de roue ou des butées d'amortissement de couvercle qui sont la plupart du temps masqués par le couvercle.When the amount of tire residue is very high, the appearance and the surface condition of the container part obtained are not very aesthetic. However, such a mixture comprising a very small amount of thermoplastic material can be used to manufacture parts that are masked or not very visible and whose functional and mechanical qualities are more important than their aesthetic qualities. For example, this invention can be applied for the manufacture of Wheel bandages or lid cushioning stops that are mostly hidden by the cover.
Enfin, on notera que lorsque la quantité de matière thermoplastique est très faible, le temps de refroidissement et de solidarisation de cette matière est court. Il est alors possible d'extraire la pièce du moule très rapidement après que la matière visqueuse a été moulée Ainsi, une telle pièce est bon marché, d'une part du fait que la majorité du matériau est recyclée et donc peu coûteuse, et d'autre part grâce à la réduction du temps de cycle de moulage du fait de la courte durée de refroidissement.Finally, it will be noted that when the amount of thermoplastic material is very small, the cooling and securing time of this material is short. It is then possible to extract the part of the mold very quickly after the viscous material has been molded. Thus, such a part is cheap, on the one hand because the majority of the material is recycled and therefore inexpensive, and on the other hand by reducing the molding cycle time due to the short cooling time.
Les résidus de broyage de pneumatiques usagés se présentent sous forme de particules de dimensions comprises entre 0,2 millimètres et 20 millimètres. Ainsi, l'invention peut être mise en œuvre avec une grande variété de résidus de pneumatiques usagés. Lorsque les particules ont une dimension de l'ordre de 0,5 millimètre ou moins, on parle parfois de poudrette de pneumatique. De préférence, les particules de pneumatique présentent des dimensions comprises entre 10 et 20 millimètres. De telles particules de dimensions conséquentes sont relativement bon marché car l'opération de broyage pour obtenir ces particules est simple. Elles sont particulièrement bien adaptées à la fabrication de pièces destinées à être masquées ou peu visibles et dont les qualités fonctionnelles et mécaniques sont plus importantes que leurs qualités esthétiques.Waste grinding residues of used tires are in the form of particles of dimensions between 0.2 millimeters and 20 millimeters. Thus, the invention can be implemented with a wide variety of used tire residues. When the particles have a dimension of the order of 0.5 millimeters or less, it is sometimes called tire crumb. Preferably, the tire particles have dimensions of between 10 and 20 millimeters. Such particles of substantial size are relatively cheap because the grinding operation to obtain these particles is simple. They are particularly well suited to the manufacture of parts intended to be masked or not very visible and whose functional and mechanical qualities are more important than their aesthetic qualities.
La pièce est choisie parmi l'un quelconque des éléments de l'ensemble constitué par un bouchon de vidange, un joint de bouchon de vidange, une grille de compost, une roue de bac de collecte de déchets, un enjoliveur de roue de bac de collecte de déchets, un obturateur de conteneur de collecte sélective, un compensateur d'insonorisation au roulement, un plot ou une butée d'insonorisation à la fermeture/ouverture du couvercle, un axe de couvercle de bac de collecte de déchets. L'invention sera mieux comprise à la lecture de la description qui va suivre, donnée uniquement à titre d'exemple.The piece is selected from any of the elements of the assembly consisting of a drain plug, a drain plug gasket, a compost grid, a garbage collection bin wheel, a trolley wheel hub cap. waste collection, a selective collection container shutter, a rolling soundproofing compensator, a soundproofing pad or stopper at closing / opening of the lid, a hopper container lid axis. The invention will be better understood on reading the description which follows, given solely by way of example.
Nous considérons par exemple un bandage de roue de bac de collecte de déchets. Ce bandage de roue est réalisé par moulage, par exemple par injection, d'une matière issue du mélange de résidus de broyage de pneumatiques usagés et de polyéthylène.For example, we consider a garbage bag wheel bandage. This wheel tire is produced by molding, for example by injection, a material derived from the mixture of grinding residues of used tires and polyethylene.
Les résidus de broyage de pneumatiques usagés sont introduits dans un mélangeur sous forme de particules de dimensions inférieures à 500 microns, appelées poudrette. Dans ce même mélangeur, on ajoute entre 5 et 30 % de polyéthylène.The grinding residues of used tires are introduced into a mixer in the form of particles smaller than 500 microns, known as crumb. In this same mixer, between 5 and 30% of polyethylene is added.
Puis, ce mélange est porté à une température sensiblement égale à 200° de sorte que le polyéthylène devient visqueux et se mélange intimement avec la poudrette. Grâce -A- à ce mélange des deux matériaux, le polyéthylène permet d'obtenir une bonne cohésion de la poudrette.Then, this mixture is heated to a temperature substantially equal to 200 ° so that the polyethylene becomes viscous and mixes intimately with the crumb. grace -A- to this mixture of the two materials, the polyethylene makes it possible to obtain a good cohesion of the poudrette.
Le mélange obtenu est ensuite moulé sous la forme du bandage de roue puis refroidi. Le bandage de roue ainsi obtenu présente des propriétés mécaniques sensiblement identiques à celles d'un bandage de roue réalisé classiquement après cuisson d'un caoutchouc revulcanisé. L'invention permet donc, à moindre coût, de fabriquer des pièces de conteneurs de déchets dont les propriétés mécaniques sont identiques à celles des pièces auparavant fabriquées. Bien entendu, le procédé décrit pour la fabrication du bandage de roue n'est pas limitatif. On pourra mettre en œuvre d'autres méthodes permettant la fabrication d'une pièce de conteneur réalisée partiellement en résidu de pneumatique et en thermoplastique. The mixture obtained is then molded in the form of the wheel tire and then cooled. The tire thus obtained has mechanical properties substantially identical to those of a wheel tire conventionally produced after firing a revulcanized rubber. The invention therefore makes it possible, at a lower cost, to manufacture waste container parts whose mechanical properties are identical to those of previously manufactured parts. Of course, the method described for the manufacture of the wheel tire is not limiting. Other methods can be used for the manufacture of a container part partially made of tire residue and thermoplastic.
