  "Werkwijze voor het herwinnen van glasvezel-, rotswol-, polyurethaanhardschuimafval en aldus bekomen eindprodukten" De onderhavige uitvinding betreft een werkwijze voor het herwinnen van afval van glasvezels, rotswol, polyurethaanhardschuim en dergelijke.

  
Isolatiepanelen worden meestal in continu vervaardigd, bijvoorbeeld door het sproeien van een schuimmengsel tussen twee deklagen uit papier, karton, aluminiumfolie of dergelijke. Na het verharden van de schuim dienen de onregelmatige randen van de aldus bekomen strook rechtgesneden te worden. Dit betekent een afval van 1 tot 1,25% van het totaal verwerkt volume. Het wegvoeren en vernietigen van dit afval wordt immer duurder, bijzonder om reden van de milieubescherming.

  
Het doel van de uitvinding is derhalve een oplossing

  
aan dit probleem te verschaffen. Hiervoor wordt een werkwijze voorgesteld die hoofdzakelijk erin bestaat : afval van glasvezels en/of rotswol en/of polyurethaanhardschuim te vermalen;

  
het aldus gemalen afval te bespuiten en te vermengen met een isocyanaat of een phenolhars; het vervolgens samendrukken en verwarmen van het geïmpregneerde afval tot het bekomen van een plaat met een soortgelijk gewicht begrepen tussen ongeveer 300 en ongeveer 800 kg/m .

  
Polyurethaanhardschuim wordt vermalen tot een korrelgrootte van hoogstens 1 cm . Het bindmiddel wordt toegevoegd

  
a ratio van 3 to 6 gewichtsprocenten.

  
Het samenpersen gebeurt bij voorkeur onder een druk begrepen tussen 15-20 kg/cm<2> terwijl de temperatuur op ongeveer
190[deg.]-210[deg.]C gehouden wordt, dit gedurende een tijd die afhankelijk is van de gewenste dikte van het eindprodukt (bijvoorbeeld drie minuten voor een plaat van 10 mm dik) .

  
Platen bekomen door deze werkwijze met hoofdzakelijk polyurethaanhardschuim als uitgangsmateriaal werden onderzocht, met de volgende uitslagen : 

  

 <EMI ID=1.1> 
 

  

 <EMI ID=2.1> 
 

  

 <EMI ID=3.1> 
 

  

 <EMI ID=4.1>

  The present invention relates to a method for the recovery of waste from glass fibers, rock wool, polyurethane rigid foam and the like.

  
Insulation panels are usually manufactured continuously, for example by spraying a foam mixture between two cover layers of paper, cardboard, aluminum foil or the like. After the foam has hardened, the irregular edges of the strip thus obtained must be cut straight. This means waste from 1 to 1.25% of the total processed volume. The disposal and destruction of this waste is becoming more and more expensive, especially for reasons of environmental protection.

  
The object of the invention is therefore a solution

  
to provide this problem. A method is proposed for this, which mainly consists of: grinding glass fiber and / or rock wool and / or polyurethane rigid foam waste;

  
spray the waste ground in this way and mix it with an isocyanate or a phenolic resin; subsequently compressing and heating the impregnated waste to obtain a plate of a similar weight comprised between about 300 and about 800 kg / m.

  
Polyurethane rigid foam is ground to a grain size of at most 1 cm. The binder is added

  
a ratio of 3 to 6 weight percent.

  
Compression is preferably carried out under a pressure comprised between 15-20 kg / cm <2> while the temperature is approximately
190 [deg.] - 210 [deg.] C for a time depending on the desired thickness of the final product (for example three minutes for a 10 mm thick plate).

  
Sheets obtained by this method with mainly polyurethane rigid foam as starting material were examined, with the following results:

  

 <EMI ID = 1.1>
 

  

 <EMI ID = 2.1>
 

  

 <EMI ID = 3.1>
 

  

 <EMI ID = 4.1>
 

  

 <EMI ID = 5.1>
 

  

 <EMI ID = 6.1>



    

Claims (7)

<EMI ID=7.1> Een onderzoek op schimmel (Aspergillus) heeft, op de drie diktes, een positief resultaat gegeven, beter dan op een klassieke houtvezelplaat. Platen volgens de uitvinding kunnen gebruikt worden tot verschillende doeleinden. Is polyurethaanhardschuim het hoofdbestanddeel, dan kunnen de platen gebruikt worden bijvoorbeeld voor verloren verpakkingen of, voor bepaalde toepassingen, zoals spaanderplaten. Zijn de platen hoofdzakelijk gevormd door glasvezels en/of rotswol, dan komen eerder akoestische toepassingen in aanmerking. EISEN.<EMI ID = 7.1> An investigation on mold (Aspergillus) has given a positive result on the three thicknesses, better than on a classic wood fiber board. Plates according to the invention can be used for various purposes. If polyurethane rigid foam is the main component, the plates can be used, for example, for lost packaging or, for certain applications, such as chipboards. If the panels are mainly formed by glass fibers and / or rock wool, then acoustic applications are more suitable. REQUIREMENTS. 1.- Werkwijze voor het herwinnen van glasvezels-, rotswol- en polyurethaanhardschuimafval, met het kenmerk dat zij hoofdzakelijk erin bestaat afval van glasvezels en/of rotswol en/of polyurethaanhardschuim te vermalen; het aldus gemalen afval te bespuiten en te vermengen met een isocyanaat of een phe- <EMI ID=8.1> 1.- Method for recovering glass fiber, rock wool and polyurethane rigid foam waste, characterized in that it mainly consists of grinding glass fiber and / or rock wool and / or polyurethane rigid foam waste; spray the waste ground in this way and mix it with an isocyanate or a phe- <EMI ID = 8.1> pregneerde afval tot het bekomen van een plaat met een soortgelijk gewicht begrepen tussen ongeveer 300 en ongeveer 800 kg/m<3>. impregnated waste to obtain a plate with a similar weight between about 300 and about 800 kg / m <3>. 2.- Werkwijze volgens eis 1, met het kenmerk dat, in het geval van polyurethaanhardschuim, het afval vermalen wordt tot een korrelgrootte van hoogstens 1 cm<3>. 2.- Method according to requirement 1, characterized in that, in the case of polyurethane rigid foam, the waste is ground to a grain size of at most 1 cm <3>. 3.- Werkwijze volgens eis 1, met het kenmerk dat het bindmiddel toegevoegd wordt a ratio van 3 tot 6 gewichtsprocenten. 3.- Method according to requirement 1, characterized in that the binder is added at a ratio of 3 to 6% by weight. 4.- Werkwijze volgens eis 1, met het kenmerk dat het 4.- Method according to requirement 1, characterized in that it <EMI ID=9.1> <EMI ID = 9.1> 5.- Werkwijze volgens eis 1, met het kenmerk dat de samengeperste massa gehouden wordt op een temperatuur van 190- 210[deg.]C tijdens het persen. 5.- Method according to requirement 1, characterized in that the compressed mass is kept at a temperature of 190- 210 [deg.] C during pressing. 6.- Plaat bekomen door toepassing van een werkwijze vol- 6.- Plate obtained by applying a method completely <EMI ID=10.1> <EMI ID = 10.1> 7.- Werkwijze voor het herwinnen van glasvezel-, rotswol-, polyurethaanhardschuimafval en aldus bekomen eindprodukten, hoofdzakelijk zoals voorafgaand beschreven. 7.- Method for recovering glass fiber, rock wool, polyurethane rigid foam waste and end products thus obtained, mainly as described previously.
