Definitions
- the present invention relates to a preparing process of cardboard or similar agglomerates, which brings essential characteristics of novelty and unquestionable advantages with regard to the already known systems used in the state of the art for preparing materials having similar - characteristics.
- the application field of the product as obtained through the process of the present invention can be very wide, since it can be very useful in the industry dedicated to the manufacture in general of panels, partitions, thermic and acoustic insulation, moulded parts of every type, - with reliefs, and so on.
- Another object of this invention is to provide a final product which can be easily moulded at will.
- Another object of the invention is to obtain a final product having characteristics allowing its surface to be suitably treated in order to be shaped, raised worked, painted, varnished, etc., so that the article as manufactured with the product of this invention can receive the wanted final finish.
- a binding agent which may consists of, for example, a soda silicate glue,so that both components intervene in relative ratios of about 60% by weight of the basic material (i.e. cardboard) to about 40% by weight of the binding agent.
- this conglomerate is broken up into sizes according to the final use to which the product is to be applied (panelling or moulding); next, the composition is left to remain to soak for a variable period of time, with stirring about every two hours; subsequently, a pressing stage is performed with several options to be later explained, with removal of the remaining liquid through the application of temperatures of a determined value, and lastly, the product is cured, allowing it to remain for a period of time of, for example, 48 hours, in a warm air atmosphere.
- the process must be performed with slight variations, depending on whether it is desired to obtain a panellable product or a mouldable product. If a panellable product, once the pulp has been prepared with the incorporation of the basic cardboard and the binding agent, it is necessary to break up the cardboard into strips, the width of which will be, preferably, between 0.5 and 10 mm, and the - length of which will be, also preferably, between 5 and 30 cm. During the rest stage of the pulp, this broken up composition is left to soak for a period of time of 10 - 20 hours, being necessary, as already stated, to - stir it every 2 hours.
- the material will be pressed according to the desired dimensions (long, wide and thick), using, with this end, a platen press fitted with overflows through which the remaining liquid is evacuated, heating the conglomerate up to a - temperature of about 170oC in order to crystallize the conglomerate, and, to this end and as an alternative, a warm air tunnel can be also utilized.
- the desired panels which being insulating as a function of the characteristics of the materials used, can be used for forming partitions, air chambers, decorating pieces, internal or external pieces of furniture, and, in general, every kind of thermic and acoustic insulating panels.
- the finishing of these panels can be obtained by varnishing, painting, relief working on their surface, and so on.
- the rest stage consists of leaving this broken up cardboard in resting state for a period of time of about 5 to 10 hours, stirring it, as stated, about every two hours.
- the product will be subjected to the action of a platen press, through which a temperature of up to 250oC is supplied it by means of suitable electric resistances providing heat.
- the material is provided with the desired volume and shape according to the application of the product, and so that the application of the temperature in this last stage provokes a greater pulp hardening.
- the last curing stage for the anticipate time of about 48 hours, in a warm air atmosphere, provides a material fully ready to be used, being preferably usable for forming different ornamental pieces and decorative figures, applicable to doors, socles, jambs, etc., and these pieces being, also, capable of receiving a final finish by means of varnish, paint, relief work, or any other desired finishing.
- a product obtained starting from recyclable cardboard and paper products is provided, which final product is also recyclable.
- the residues from this agglomerate disintegrate fully when soaked in water.
- the outcoming product has a high ignifugous power, making it particularly applicable to the manufacture of insulating panels and similar, as above stated.
