Abstract

Glass fibre matting process.. GF-. by using low-pressure on a matting which incorporates air channels in its surface. This facilitates the removal of air-trapped between the matting and the laying surface, but the pressure must be maintained until the air channels have disappeared. The glass fibres may be mixed with fillers, pigments, abrasives etc. in addition to a duroplast such as polyester.

Description

Verfahren zum Belegen großer Flächen mit Glasfasermatte Die vorliegende Erfindung betrifft ein Verfahren zum Belegen großer Welchen mit vorimprägnierter Glasfasermatte.Method for covering large areas with fiberglass mat The present The invention relates to a method for covering large wichers with pre-impregnated Fiberglass mat.

Eine vorimprägnierte Glasfasermatte besteht gewöhnlich aus einer Glasfasermatte mit verhältnismäßig langen Fasern, et-WS 50 mm, die mit einer Mischung aus Duroplast, gewöhnlich Polyester, Füllstoff, Färbpigment, Schleifmittel, Härtungsmittel, Verdickungsmittel und anderen speziellen Chemikalien imprägniert ist. Diese Matte soll nach ihrem "Reifen" eine hohe Viskosität haben, was mittels geeigneter Chemikalien, die Eindickung bewirken, erreicht wird. Der Pressvorgang verlangt nämlich eine hohe Viskosität, damit der Kunststoff während des plastischen Fließens Glasfasern und Füllstoff transportieren kann, ohne die Eaterialien voneinander zu trennen, und damit die Matte während des Hantierens nicht klebt.A pre-impregnated fiberglass mat usually consists of a fiberglass mat with relatively long fibers, et-WS 50 mm, with a mixture of thermoset, usually polyester, filler, coloring pigment, abrasive, hardener, thickener and other special chemicals. This mat should be after your "Tires" have a high viscosity, which by means of suitable chemicals, the thickening effect is achieved. The pressing process requires a high viscosity, so that the plastic transport glass fibers and filler during the plastic flow can without separating the Eaterialien from each other, and thus the mat during the Handling does not stick.

Bei Anwendung einer solchen Matte zur Bekleidung einer größeren ebenen Fläche, beispielsweise einer Tischplatte oder dergleichen, ist das Risiko groß, daß beim Pressen Luft zwischen Matte und Preßlatte eingeschlossen wird,insbesondere wenn man nicht hohem Preßdruck, etwa 50-150 kp/cm², arbeitet.When using such a mat to cover a larger flat area Surface, for example a table top or the like, the risk is high that when pressing air between Mat and press slat included is, especially if one does not work with high press pressure, about 50-150 kgf / cm².

Bei größeren Flächen ist die Anwendung eines hohen Preßdruckes oft nicht ermöglicht, da die presse unwirtschaftlich grobe Abmessungen erhalten würde, und da der zu bekleidende "erkstoff, z. 3. Holz, so große Drücke nicht aushält. Man ist also gezwungen, 2mit niedrigen Freßdrücken, etwa der Größenordnung 5-50 kp/cm , zu arbeiten. Bei niedrigen Preßdrücken ist jedoch die Gefahr von Lufteinschlüssen sehr groß. vurch Luft einschlüsse bilden sich in der fertigen Oberflache Blasen, die zu einer Schwächung der Oberfläche und oft zu einem Brechen der Bekleidungsmatte führen.In the case of larger areas, high pressure is often used not possible, since the press would get uneconomically coarse dimensions, and since the material to be clad, e.g. 3. wood, cannot withstand such great pressures. So you are forced to use low feeding pressures, around 5-50 kp / cm to work. At low press pressures, however, there is a risk of air inclusions very large. air inclusions form bubbles in the finished surface, which can weaken the surface and often break the garment mat to lead.

Die vorliegende Erfindung bezweckt ein Verfahren, das Pressung mit niedrigem Druck ohne Gefahr von Lufteinschlüssen der vorstehend beschriebenen Art ermöglicht.The present invention aims a method that pressing with low pressure without the risk of air inclusions of the type described above enables.

Dies wird gemäß der Erfindung dadurch erreicht, daß die Oberfläche der vorimprägnierten Matte mit Kanälen versehen wird, durch die die Luft bei Beginn des Pressens entweichen kann, so daß die Masse keine Luftblasen einschließt. Die Kanäle sind vorzugsweise auf der der Preßplatte zugewandten Seife der Matte angeordnet, insbesondere bei Bekleidung von Gegenständen aus porösem Material, WO die zwischen Matte und Gegenstand eingeschlossene Luft in den Gegenstand hineingedrückt wird. Bei einer vorzugsweisen Ausführungsform haben die Kanäle in der Matte einen von der Mitte der Matte nach außen zu ihren Kanten zunehmenden Querschnitt. Dank dieser Ausbildung wird der Luft eine vorteilhafte Bewegung nach außen vermittelt, wobei Material und Luft von der ,atten- und Preßplattenmitte nach außen zu den Kanten gepreßt, und gleichzeitig die Kanäle zugedrückt und mit Material gefüllt werden, wodurch sie verschwinden. Die Matte erhält dadurch eine gleichmäßige glatte Oberfläche ohne Lufteinschlüsse, Die sich konisch erweiternde Form der Kanäle macht ein Verbleiben von Luft in der ;;atte unmöglich.This is achieved according to the invention in that the surface the pre-impregnated mat is provided with channels through which the air at the beginning the pressing can escape so that the mass does not include any air bubbles. the Channels are preferably arranged on the soap of the mat facing the press plate, especially when clothing items made of porous material, where between Air trapped in the mat and the object is forced into the object. In a preferred embodiment, the channels in the mat have one of the center of the mat outwards towards its edges increasing cross-section. thanks to this Training gives the air an advantageous outward movement, whereby Material and air from the middle, atten- and press plate center outwards to the edges pressed, and at the same time the channels are closed and filled with material, making them disappear. This gives the mat an even, smooth surface without air inclusions, the conically widening Shape of the channels makes it impossible for air to remain in the ;; atte.

Das Verfahren gemäß der Erfindung ermöglicht das Ausführen des Pressens mit verhältnismäßig niedrigem Druck unter hnwendung herkömmlicher Pressen. Die Methode wird hierdurch wirtschaftlich und macht es überhaupt möglich, Material der beschriebenen Art zur Bekleidung größerer Flächen anzuwenden.The method according to the invention enables pressing to be carried out with relatively low pressure using conventional presses. The method This makes it economical and makes it possible at all to use the material described Type to be used for covering larger areas.
