Definitions

  • the present invention consists in a thermal insulation board made of ground paper in a mixture with natural fibers such as jute or the like.
  • a thermal insulation panel of the same type is e.g. described in patent application DE-A-35 45 001. Then paper is separated into the individual cellulose fibers by grinding until a woolly state is reached and mixed with vegetable or animal fibers with a length of 2-10 cm. The connection of the fibers is brought about by glue, to which fire-retardant or rot-preventing substances have also been added, by pressing the mixture in a mold and solidifying it with superheated steam and then drying it.
  • thermal insulation boards have at most insignificant proportions of synthetic chemicals, they are therefore particularly environmentally friendly and meet modern building biological requirements.
  • a major problem in the manufacture of such panels is the previously unavoidable inhomogeneities in the end product, which on the one hand impair the mechanical strength and on the other hand also cause the bond to break up during storage and transport.
  • the object of the present invention is therefore to improve such thermal insulation boards, in particular to increase their mechanical strength, to bind the fibers in a more durable manner and to provide a method and an apparatus therefor with the aid of which such boards can be produced.
  • the thermal insulation board according to the invention is obtained from a mixture of shredded and with putrefactive additives, such as preferably borates, pretreated newspaper or the like, paper free of surface coatings or fillers and natural fibers, and glues and / or reaction aids, characterized in that the shredded paper in Flakes of 1-5 mm edge length are present and the natural fibers have a length of 5-100 mm.
  • putrefactive additives such as preferably borates, pretreated newspaper or the like, paper free of surface coatings or fillers and natural fibers, and glues and / or reaction aids
  • the nature of the natural fibers to be used is largely uncritical with regard to their nature, in particular jute, sisal, cotton, coconut, flax, those made from recycling or waste material from spinning mills or processed material made from straw or wood or animal hair, such as preferably wool, preferably one Length from 5 to 100 mm.
  • Balsam resins such as rosin, starch or lignin glue, rubber or else cement, gypsum, aluminum sulfate and water glass are preferably used as glues and reaction aids.
  • the plates can be produced in such a way that the substances are mixed and loosened, placed in a mold, compressed to the desired density and treated with hot air and / or superheated steam and dried.
  • the lignin components contained in the paper are activated and used as binders.
  • a particularly effective method according to the invention consists in first premixing paper flakes and fibers, blowing the mixture into a mixing vessel and adding glue or glue and reaction aids, if necessary in the form of an aqueous solution, in countercurrent, then loosening the mixture, in free case in introduces and compresses a molding station and then treats and dries it with hot air or hot air and steam.
  • the glues and optionally reaction aids can be injected into the flake and fiber stream in powder form, in molten form or as an aqueous solution and essentially settle on the surfaces of the particles.
  • the desired orientation of the fibers and the interlocking or matting of the fibers and flakes are achieved by compacting onto plate form, which improve the bond and reduce the need for glue.
  • the compacted mass is then treated with hot air or hot air and steam, causing the glue components to flow and then set.
  • the mixture then collected and loosened again mechanically can be treated with superheated steam (or hot air if the moisture inherent in the fibers is sufficient) during the free fall into the forming station to stretch and swell the fiber components, depending on the nature of this, what is obtained Product can improve.
  • the loosening and separation of the components before they are introduced into the mold is of major importance. It is therefore further proposed to collect (continuously) the mixture of the components produced by countercurrent in a container provided with a loosening mixing element, to discharge it into a chute with the aid of a lock, preferably a cellular wheel lock, and to mix and loosen the mixture there again.
  • a lock preferably a cellular wheel lock
  • the "setting" of the plates takes place under mechanical pressure, whereby hot steam or hot air or both, depending on the moisture available and required for the activation of the glues used, is passed through the press material under excess pressure and then dried, which e.g. can be done by passing dry air through, which can also be sucked through to generate a negative pressure and to accelerate evaporation.
  • the process can be varied during filling in such a way that different mixtures are produced in separate mixing devices and these are successively layered on top of one another and then pressed.
  • the outer layer can have higher proportions of glue and paper in order to make them smoother or to cover them with the aid of the glue, or, depending on the application, also increasingly contain longer or shorter fiber proportions.
  • the material trickling out of the chute be placed on a (perforated) conveyor belt to which an upper belt (top belt) is assigned.
  • the latter has an inclined feed area that narrows in the direction of transport, which lowers to the desired level of the plate thickness and runs into the hot steam and / or hot air supply and the drying station.
  • the product to be compacted also be guided laterally, for example by its own belts.
  • the device according to the invention consists of a cyclone with an upper tangential feed of the fiber / flake mixture and approximately opposite flow of the glue components. This mixture rotates peripherally and reaches the bottom of the cyclone, where it is collected and monitored by a level indicator. Filter bags are provided on the head side for dedusting.
  • Rotating comb tine shafts are arranged in the collecting area, underneath there is a rotary valve which doses the material onto another mixing element, whereby it can be steamed if necessary. Below the latter mixing element there is a chute and below this the filling station, with stripping shafts being provided at the outlet.
  • the cyclone 1 has two mutually directed, approximately tangential material inputs, the feed 2 for the premixing of paper flakes and natural fibers.
  • This premix contains the essential substances, ie, in addition to the fibers and paper flakes, for example also the putrefactive substances which can be added to the paper during grinding.
  • the glue is blown into the rotating mixture in powder form or as a melt or in aqueous solution.
  • the storage container 4 with mixer 5 and the metering container 6 with screw discharge 7 are used to produce the glue.
  • the material entry is preferably carried out with little air at high speed, for which there are suitable devices.
  • the excess pressure generated by the material input in the interior of the cyclone 1 serves at the same time for dedusting by the filter bags 9 at the top of the cyclone 1.
  • the cyclone is equipped with a fill level control 11, which throttles the material supply before being overloaded.
  • Mixing elements in the form of comb teeth shafts 10 are arranged on the bottom of the cyclone 1, which homogenize the material and prevent premature setting of the glue by constant movement.
  • a lock preferably a cellular wheel lock 12, which doses the material into the chute 13.
  • Evaporation 14 can be provided below the cellular wheel sluice, which serves to pre-swell and stretch the fibers.
  • This chute 13 is preferably designed to widen downwards in order to prevent caking of glue components when the addition is dissolved or melted.
  • a fill level control 15 and underneath the molding station which is designed here as a plurality of molding boxes 16 open at the top. The material flows into these boxes 16 in a completely loosened state.
  • the boxes 16 are slidably mounted.
  • the press After filling a box, it arrives at a press 17 in which the loose bed is compressed to the desired density.
  • the press consists in a simple way of a perforated sheet, just like the molded boxes, adapted to the dimensions of the boxes, which is placed on the filling and pressed down.
  • the perforated plate can remain on the box until it is removed from the mold, but it is also possible to apply your own perforated plates in the following stages for holding down and setting. This creates the desired orientation and entanglement of the fibers, which mechanically strengthens the bond.
  • scraper shafts 18 can be arranged, which ensure a uniform degree of filling.
  • the device should therefore preferably be started up and kept in continuous operation.
  • the temperature and moisture treatment stages follow the press 17. First, hot air and hot steam can be blown in to activate the glue and the activatable lignin components 19.
  • Compressed air 20 can then be blown in for drying and then, in a further stage 21, either further drying air can be supplied, the exhaust air in 20 of which can be used for predrying, or it can also be dried to residual building physics with the aid of a vacuum in 21.
  • the mold boxes are circulated after removal from the mold.
  • the degree of filling can be regulated via the scraper shafts 18 if they are height-adjustable.
  • the temperature and humidity control is preferably carried out as follows: A mixture of hot air and superheated steam is driven in through the openings in the perforated plate below, the temperature and mixing ratio of which can be regulated.
  • the gas mixture is fed into the mold until the material is heated to just below the boiling point of the liquid it contains.
  • the moisture must be sufficient to enable the setting and reaction specifications, including the reactivation of the glues contained in the paper.
  • the drying process of the plates does not take so long until the moisture diffuses from the inner areas of the plate through the salts and fiber materials to the outside is, but is carried out of the plate much faster by the air flow, which also brings evaporation energy with it.
  • Another part of the evaporation energy is contributed by controlling the pressure in the closed form.
  • a moisture residue that slightly exceeds the building moisture (approx. 10% moisture weight) can remain in the plate. As soon as the moisture has dropped so far, the plate can be dried and switched off and packed.
  • Treating the wet plate with hot air can optionally post-cure certain adhesives, e.g. Effect lignin glue.
  • the energy management of the gas central system can be optimized by minimizing heat losses through thermal insulation of the temperature-conducting lines and surfaces and good seals, as well as recovering heat from the post-drying of the plates, the heat of condensation from the moist drying exhaust air and the superheated steam-hot air excess from steaming.
  • the vaporization mixture can also be obtained by reheating the moist drying exhaust air (containing steam) and the moisture can thus be circulated.
