Definitions

  • the invention relates to a fiber mat according to the preamble of claim 1, a molded part produced from this fiber mat and a method for its production.
  • DE 2845117 A1 already discloses a process for the production of plate material which can be pressed into molded parts from cellulose-containing material and at least one thermoplastic binder, in which the cellulose-containing material and the thermoplastic binder are mixed and the mixture is formed into plate material in the heated state.
  • the cellulose-containing material is defibrated into fiber and mixed with the thermoplastic binders, a fleece is formed from the mixture and the fleece is compressed to the plate material by the action of heat and pressure.
  • Waste of cellulose materials such as paper, Cardboard, textiles, etc., however, may also be used, possibly even in a predominant proportion of peat, bark and, in a particularly preferred manner, dried plant parts of annual plants such as straw or the like.
  • pulp-containing material such as paper and cardboard waste is broken down into particles with dimensions of approximately 5 ⁇ 5 mm and then fiberized, so that the maximum fiber length is approximately 5 mm.
  • a dry powder of fibrous particle nature made of polyethylene is used as the thermoplastic binder. No lengths are given for these particles.
  • the molded parts made from this sheet material have a limited strength, so that they usually also contain thermosetting binders.
  • the plastic is in the form of fibers with a length in the range of 30-100 mm and the cellulose fibers have a length of 10-100 mm, a relatively dimensionally stable fiber mat can be obtained, in particular after needling, which can be handled without problems until further processing ,
  • the molded part obtained from this is given the great length of the cellulose fibers, great strength and impact resistance, especially at very low temperatures.
  • the fact that no thermosetting binders are required means that the molded parts can be produced inexpensively, are light in weight and are largely free of emissions and odors and are easily recyclable.
  • Preferred cellulose fibers are those which have a length in the range of 50-100 mm, and in particular those whose average length is 70 mm +/- 20%. Their share in the total weight of the fiber mat can be between 10 and 90%.
  • the cellulose fibers advantageously consist of natural fibers from annual plants, such as hemp, flax, sisal or kenaf or technical viscose fibers, and also from cellulose regenerate, that is to say synthetic cellulose, which is preferably obtained from wood but does not contain its lignin components. Mixtures of the aforementioned various cellulose fibers can also be used.
  • the cellulose fibers Before the formation of the fiber mat, the cellulose fibers can have been chemically, chemically-physically or physically pretreated in a known manner, for example bleached, mercerized, alkalized, ace- ethylated or provided with an adhesion promoter, flame retardant or water repellent.
  • Polypropylene is preferably used for the plastic fibers. However, they generally consist of textile fibers, ribbon fibers or fibrous film chips made of polyolyphins, engineering plastics and / or copolymers, as well as mixtures of several polymers (e.g. as bico fibers). In order to obtain a homogeneous fiber mixture, the plastic fibers should have a fineness in the range of 3.3-25 dtex.
  • auxiliaries in particular processing aids such as antistatic agents or adhesion promoters, but also water repellents, flame retardants and additives can be added during the manufacture of the mat. However, their total amount should not exceed 10% of the total weight of the mat.
  • the fiber mat can be covered on at least one side with a light fleece made of e.g. polypropylene / polyester and with a basis weight of up to 300 g / m 2 are covered.
  • the connection between the fiber mat and light fleece is expediently made by needling.
  • the manufacture of the fiber mat basically takes place in a known manner, as is known for example from DE 2845117 AI.
  • the main steps in mat formation are as follows:
  • the corresponding fiber components are delivered in bale form to a processing plant and fed via a bale opener with metering devices, pre-opener, fine opener, fiber finisher, mixing chamber and box storage as a fiber mixture to the fleece system.
  • the bale opener releases the cellulose and plastic fibers from the respective bales.
  • a weighing device doses the desired mixing ratio of the fibers on a collecting belt.
  • the material is transported from the collecting belt to a mixer opener (pre-opener) in which the fiber components are roughly mixed.
  • a mixer opener pre-opener
  • the following fine opener is used to shorten, refine and clean bast fibers.
  • This device is equipped with a trough feed and a sawtooth barrel. Cockroaches and other contaminants are separated by means of expanded metal gratings arranged on the circumference of the tambour.
  • the fibers are treated with a spray system with liquid additives such as water repellents, lubricants, flame retardants, antistatic agents, adhesion promoters and the like.
  • a stationary rotary separator in the bunker ceiling ensures an even layering of the fibers and the formation of a fiber sandwich.
  • This fiber sandwich is milled vertically by an emptying machine.
  • the box feeder doses the fiber mixture into a volumetric filler shaft using a flat cloth belt. This doses the fiber cake into the fleece system via a dosing scale.
  • the fleece system consists of a pre-fleece and an end fleece.
  • a pre-web is produced in the pre-web former either by a carding system or an aerodynamic system.
  • the fibers are placed in an oriented manner.
  • the homogeneously premixed fiber components in the form of the preliminary nonwoven are broken down from a high-speed sawtooth turret to individual fibers. Due to the centrifugal force, the fibers detach themselves from the tambour and are blown onto the screen surface by the pleasure flow of a cross-flow fan. The simultaneous suction by vacuum fans causes the formation of tangled fleece on the screen surface.
  • the subsequent needling of the fiber mats is a mechanical consolidation, which is based on a weaving of the fibers and the increase in friction between the fibers caused by the compaction of the fleece.
  • the fleece is first pre-compacted by rolling or a press belt and then fed to the needle machine.
  • the endlessly produced needle felt is then cut to mat dimensions for pallet stacking or rolled goods by means of a cross-cut and a longitudinal cut device.
  • the mats will stored on pallets via an automatic stacking device.
  • the needle fleece is wound onto carrier sleeves.
  • the production of the molded parts can take place spatially and temporally separately from the fiber mat production. It is possible to produce the molded part together with a lamination from a fabric, a decorative film or the like in the so-called one-shot process. This can significantly reduce production costs.
  • the fiber mat is first fed to a preheating station, in which it is heated to approximately 180 degrees Celsius. At the same time, pre-compression takes place. At this temperature, the plastic fibers melt so that they lose their fiber structure.
  • the heated fiber mat is then introduced together with the lamination into a molding press, in which the molding receives its shape and at the same time the lamination is connected to the molding by the molten plastic.
  • the molding press has a temperature of less than 80 degrees Celsius, so that the molded part is cooled and the molten plastic solidifies, as a result of which a dimensionally stable molded part can be removed from the molding press.
  • Such a molded part which was made from 50 percent by weight of cellulose fibers and 50 percent by weight of polypropylene fibers, has, for example, a density of 1.0 g / cm 3 , a water absorption of 4.5 percent by weight, a flexural modulus of 3500 N / mm 2 and a bending strength of 65-70 N / mm 2 .

Abstract

L'invention concerne un mat de fibres servant de produit intermédiaire pour produire des pièces moulées d'épaisseur de paroi de préférence identique, consistant en fibres essentiellement à base de cellulose, comprimées avec une matière plastique en mélange homogène. La matière plastique se présente sous forme de fibres d'une longueur de l'ordre de 30 à 100 mm et les fibres de cellulose présentent une longueur de l'ordre de 10 à 100 mm. Les fibres de cellulose se composent de préférence de fibres naturelles obtenues à partir de lin, de sisal, de chanvre, de kenaf, de fibres de viscose techniques ou de mélanges de ces constituants, ou bien à partir de régénérat de cellulose, en d'autres termes notamment de cellulose synthétique issue du bois.
