Definitions

  • Wood fibre insulating material and method of producing the same
  • the present invention relates to a wood fibre insulator according to the preamble of the claim, particularly a wood fibre insulation board.
  • an insulator such as this comprises finely ground wood material or material derived from wood, such as wood fibre, wood chip, cellulose fibre or paper fibre or similar.
  • the present invention also relates to a method according to the preamble of Claim 6 of producing a wood fibre insulator.
  • Thermal insulators made of wood have long been produced. Initially, sawdust and wood chips produced by a rotating-blade planer, were used. Later, wastepaper was defibred and, later still, wood as such. In this way, a thermal insulator is generated which is easy to blow, and which can be blown either dry or damp into the place that is to be insulated.
  • thermal insulators for houses erected on-site should already be in the form of boards, at least for their use in the floors and walls.
  • Rock wool, glass wool, polystyrene foam and polyurethane foam are already marketed in the form of boards.
  • rock wool and glass wool comprise fibrous materials, the fibres of which are bound together with resins, generally with phenol-formalin resin.
  • the present invention is based on the principle that material which can be recycled, and which is generated for instance as waste from other activities, is used for binding the fibres.
  • a most advantageous solution for building work in general is that it is possible to use waste material or waste materials.
  • wood waste or woodworking waste which can be defibred by dry refining or refining in slightly damp conditions is an advantageous material either together with or separate from waste paper or cardboard used for packing.
  • a thermal insulation panel or board which comprises organic fibres or their derivatives or their recycled products is produced in such a way that the fibres are bound to each other by polyolefin fibres that are made of waste plastic or recycled plastic.
  • a plastic film which is designed to be a binder, or a polymer which melts in similar conditions, for instance polypropylene, is defibred by using heat and kinetic energy to form fibres or/and thin mini films, which are blown in between organic fibres and/or wood chips.
  • the product according to the present invention is mainly characterized by what is stated in the preamble of Claim 1.
  • the method according to the present invention is, in turn, characterized by what is stated in the preamble of Claim 6.
  • the binding fibres are blown, either hot or warm, in between the basic fibres, in which case it is not necessary to introduce much, if any, heat while the finished panel is being worked on. Furthermore, it is possible to avoid separate breaking open of binding fibre packages and scattering of the binding fibre.
  • Figure 1 shows a basic diagram of a simplified structure of the defibring apparatus used in the present invention
  • figure 2 shows a belt which is used for shaping the fibre insulation panels
  • figure 3 shows an aggregate of organic fibres and plastic.
  • recycled plastic and waste paper or/and waste wood are used for producing thermal insulation panels, and particularly as a binder for binding together organic fibres.
  • the basic fibres used for insulation panels i.e. insulation boards, are organic fibres, typically wood fibres, wood chips, cellulose fibres, lignocelluloses fibres, or fibres which are sourced from their derivatives or which are composed of them, or fibres which are made from recycled products of organic materials, such as fibres made from recycled paper or recycled cardboard.
  • the basic fibres and the binder fibres are mixed together and shaped as desired, for instance into a board.
  • the quantity of binding fibre used is generally approximately 1-50 %, especially approximately 1-25 %, most suitably approximately 2-20 %, of the weight of the base material fibres.
  • the dimensions of the plastic fibres are in the range that corresponds to the dimensions of the organic fibres, i.e. approximately 0.1-100 mm, typically approximately 0.5-50 mm, especially approximately 0.7-25 mm.
  • the panel blank which is made for instance by blowing and shaping onto a moving belt, and then to cool it before longitudinal cutting.
  • the binder of the fibre insulator comprises totally recycled material.
  • the percentage of recycled plastic in the binder of the insulating material is approximately 20-100 % by weight, especially approximately 50-100 % by weight.
  • the temperature should be occasionally over 120 °C.
  • fire retardants such as boric acid, borax and boron salts or magnesium sulphate and similar salts
  • This solution can be carried out in such a way that the necessary fire retardants or part of them are added during the stage in which the polymer material is melted, in which case the crystal water released from the retardants blows fine bubbles into the polymer fibres, which bubbles, in turn, increase the insulating capacity of the insulator.
  • Antimony oxide is a well-known effective fire retardant for protecting polymers. This, too, can be added during the melting stage.
  • the quantities of fire retardants and anti-mould agents added are approximately 0.01-20 % by weight of the binder quantity, especially approximately 0.05-10 % by weight.
  • the binding plastic fibres are prepared at the same time as are the basic fibres (i.e. organic fibres) but in a separate device, and are then blown together in a molten and adhesive state.
  • the basic fibres and the binding fibres together are post-heated in such a way that the binding fibres at least partly are adhered to the basic fibres by melting.
  • the molten waste plastic is fed onto a rotating disc, from where it is ejected in a fibrous state by the centrifugal force.
  • the rotating disc can be heated.
  • fibres are generated from thermoplastic molten material by pouring the material through a Laval nozzle by applying air pressure in such a way that the air pressure generates supersonic speed.
  • molten rock is defibred with the help of a rotating cylinder, in a gas flow channel, which flow defibres and cools the material.
  • US Published Patent Application No. 20090068430 describes how a thermal insulator is produced from organic fibres by using polyvinyl alcohol fibres as binder, and polyolefin fibres that become soft when heated.
  • the insulator comprises salts of K and P, in which case it is possible to use the insulator (to supplement boron compounds) as fertilizer, too.
  • the product is said to be biologically decomposable.
  • insulation boards are afforded high compressive strength by using waste plastic granules 22-37 % of the board weight to bind the fibres.
  • approximately 13 % of thermoplastic binding fibres are used in the application.
  • the production engineering is similar to that used for producing cardboard on a paper machine, where material is imported layer by layer until the desired thickness is reached.
  • the defibrator for defibring the polymer material must be such that it is suitable for waste and recycled polymers, including impurities.
  • transportation of heat into the polymer mass takes place in such a way that a feed screw compresses plastic into a cylinder, the walls of which are heated and which thus melt the polymer.
  • the defibring of the polymer takes place by means of one or several simultaneous mechanisms.
  • Kinetic energy can be brought into the molten polymer mass either by a jet of air or by expanding the air which has remained inside the mass, or, alternatively, by means of a rotating disc.
  • a thermal insulator called rock wool, for instance, is produced from molten rock material.
  • the objective is achieved, i.e. an insulation panel that maintains its shape.
  • the required thickness of the board is easily achieved by adjusting the speed of the conveyor belt/mould belt.
  • the properties of the product are, in turn, modified by changing the ratio between the basic fibres and the binding fibres.
  • FIG. 1 shows a feed funnel 10 for waste plastic, a feed screw 13 which is driven by a motor 11, a heat jacket 12 which can be oil-heated or electrically heated, and a disc for disintegrating 14, and an air nozzle 15.
  • Figure 2 shows a conveyor belt 21 and a smoothing device 22 and the recycle 23, 24 to the feed.
  • FIG. 3 shows the structure of a finished product.
  • the shaded fibres 32 are polymers, which bind together for instance wood fibres 31.
  • a defibrator The operation of a defibrator is based on the simple idea of having only a rapidly rotating disc 14, onto which a screw 13 feeds a molten polymer mass, and from which the exiting mass meets a jet of disintegrative air or inert gas which is generated by a blower and a nozzle 15.
  • the polymer fibres 18 are conducted with the help of an air flow into a flow of organic fibres, preferably immediately after they have exited from the defibrator through the outlet pipe 16.
  • the conveyor belt 21 is equipped with edges and a planing blade 22 which removes excess mass and returns that mass to the feed via the blower and the feeding line 24.
  • the breaking disc is electrically heated, in order to prevent the molten polymer from solidifying onto its surface.
  • a finished thermal insulation panel by increasing the quantity of polymeric binding fibres, and/or, by increasing the density of the insulation panel by means of compression. It is possible to regulate the basic density of thermal insulation panels by modifying the degree to which the organic fibres are refined. The finer the degree of defibring or fibrillating, the lower the density achieved. Typically, the densities are within the range of 30-70 kg/m . However, care should be taken to ensure that there are enough fire retardants, i.e. boric acid and sodium tetraborate, to smother a smouldering thermal insulation panel. Generally, a total quantity of approximately 5.5 % of these boron compounds is enough for fire retardant purposes; also, a suitable quantity of MgS0 4 is used, in order to ensure that the material aggregate fulfils the anti-smouldering requirements.
  • fire retardants i.e. boric acid and sodium tetraborate

Abstract

Panneau d'isolation thermique constitué de fibres de matrice organiques, d'un liant qui relie ces fibres entre elles et de tout additif, et son procédé de fabrication. Selon cette invention, les fibres organiques (31) sont reliées ensemble par des fibres de polyoléfine (32) tirées de déchets de plastique ou de plastique recyclé. Ainsi, les matières premières du panneau d'isolation sont très bon marché et les différents composants peuvent être produits indépendamment les uns des autres. Une fois produites, les fibres du liant sont injectées par soufflage entre les fibres de matrice, fondues et collées à ces fibres.
