Definitions
- the present invention relates to a method for the manufacture of fibreboards by distributing between two plates a paper material ground to a fleece and subsequently subjecting the same to pressure and heat.
- fibre or particle boards have a wide field of application within the building industry and the manufacture of furniture. These boards may be of different quality and nature depending on the field of application. More strongly compressed boards are used, for example, as a substitute for the more expensive timber in furniture framework and fittings. More loosely compressed fibreboards may be used as partly insulating layers in walls, floors and roofs.
- the method of manufacturing fibreboards or particle boards is generally known, and for this purpose wood particles of different qualities and coarsenesses are used, and in this way boards of different properties are obtained.
- a bonding agent of some kind has to be blended into the fleece material.
- this bonding agent usually is in the form of a powder or grain the mixing can bring about problems as the fleece material quite often has a different grain size.
- coarser particles when coarser particles are used these should not be subjected to the mechanical effects which a mixing process involves, as the particles are brittle and break readily.
- Particle boards in accordance with known manufacturing processes once they are made into boards, cannot be converted, since the bonding agent cannot be reheated and act again as a bonding agent.
- the paper material ground to a fleece is spread out between two plates whereafter it is subjected to pressure and heat.
- the paper material should be coated at least on one side with a thermoplastic which, when the material has been ground to a fleece, will be uniformly distributed in the fleece mass.
- a paper material of the abovementioned type is found to be obtainable at a low price in the packaging industry which manufactures non-returnable packages for liquids from paper coated with thermoplastics.
- a certain wastage always exists on changing of the material rolls, edge shearing, faulty printing or the like.
- This waste material is of little use in other fields and commands therefore a considerably lower price than does wood as a raw material for the conventional manufacture of particle board.
- boards of the homogeneous types described above may also be manufactured, which may be given a desired three-dimensional shape already during manufacture.
- thermoplastic as a bonding agent manufactured in accordance with the invention and afterwards under pressure and in moulds impart to them a desired three-dimensional shape.
- thermoplastic In the manufacture of porous fibreboards a homogeneous paper layer, coated at least on one side with thermoplastic, is introduced between each pressure plate and the fibre mass. This thermoplastic surface is located nearest the fibre mass and during heat treatment this surface layer also melts and bonds together the paper fleece with the outer homogeneous paper layer.
- a pressure treatment at an appreciably lower pressure is required than for a corresponding homogeneous board.
- a pressure of approx. 20 kN/m2 is required.
- the temperature is to be approx. 200 o C. A higher temperature is required due to the fact that the air caught between the fibres causes a greater loss of temperature, when the fibre material is pressed.
- the time duration of pressure application is dependent of the thickness of the fibre material to be pressed and the grade of porousity wanted.
- the fibre mass then still contains a quantity of air, so that this type of board can have wide uses in the building industry as a partly insulating building material, especially in countries with a shortage of timber.
