Verfahren zur Herstellung stranggezogener, kunstharzgebundener Profile.Process for the production of extruded, synthetic resin-bonded profiles.

Die Erfindung betrifft ein Verfahren zur Herstellung stranggezogener, kunstharzgebundener Profile aus Glasfäsermaterial oder Draht, wobei das zu ziehende Material anschliessend in einer beheizten Ziehform profiliert wird.The invention relates to a method for producing extruded, Resin-bonded profiles made of fiberglass material or wire, with the material to be drawn then in a heated drawing die is profiled.

Es ist bereits bekannt, Glasfaser-Kunstharzprofile im Strangziehverfahren herzustellen. Dabei werden die sogenannten· Rovings, das sind die aus den einzelnen Pasern bestehenden Stränge, durch ein Harzbad gezogen und anschliessend in einer beheizten Ziehform profiliert und gleichzeitig ausgehärtet.It is already known to use fiberglass synthetic resin profiles in an extrusion process to manufacture. The so-called rovings, that is, those consisting of the individual pasers, are used Strands, drawn through a resin bath and then profiled in a heated drawing mold and hardened at the same time.

Das bekannte Verfahren weist jedoch verschiedene Mängel auf die unter anderem darin bestehen, dass die zur Tränkung der Rovings verwendete Harzmischung eine zu hohe Viskosität auf-However, the known method has various shortcomings which, among other things, consist in the fact that the resin mixture used to impregnate the rovings has too high a viscosity.

weist, wodurch eine ungenügende Durchtränkung der Pasern erzielt würde. Auch wurden die in das Harzbad einlaufenden Rovings vorgewärmt und die Harzmischung wurde mit Verdünnern· versetzt. -Durch eine Erhöhung der Temperatur des Harzbades, oder durch die Zugabe von reaktiven Verdünner verläuft die Reaktion zwischen Harz und Härter schneller und die Viskosität der Harzmischung steigt noch weiter an. Es entstehen dadurch W grosse Harzverluste und andere Fabrikationsschwierigkeiten.shows, which would result in insufficient impregnation of the pasers. The rovings entering the resin bath were also preheated and thinners were added to the resin mixture. - By increasing the temperature of the resin bath or by adding reactive thinners, the reaction between resin and hardener proceeds faster and the viscosity of the resin mixture increases even further. This creates large W resin losses and other manufacturing difficulties.

Die Aufgabe der Erfindung besteht darin, die Mängel des Vorbekannten zu vermeiden und ein verbessertes Verfahren in dieser Hinsicht zu entwickeln.The object of the invention is to overcome the shortcomings of the prior art avoid and develop an improved procedure in this regard.

Die vorgenannte Aufgabe wird erfindungsgemäss dadurch gelöst, dass die mit Kunstharz getränkten Rovings zwischen dem Kunstharzbad und der Ziehform erwärmt werden.The aforementioned object is achieved according to the invention in that the rovings impregnated with synthetic resin are located between the synthetic resin bath and the drawing die are heated.

Der Vorteil der Erfindung besteht insbesondere darin, dass eine besonders gute Durchtränkung der Rovings durch die Erwärmung des Harzes niedriger Viskosität zwischen dem Kunstharzbad und der Ziehform und einer Temperaturerhöhung der in die Ziehform einlaufenden Rovings erzielt wird.The advantage of the invention is, in particular, that the rovings are soaked through particularly well as a result of the heating of the resin of low viscosity between the resin bath and the drawing die and an increase in temperature of the rovings entering the drawing mold is achieved.

Es empfiehlt sich, zur Erwärmung der mit Kunstharz getränkten. Rovings zwischen dem Kunstharzbad und der Ziehform eine Be-It is recommended to warm the soaked with synthetic resin. Rovings between the synthetic resin bath and the drawing mold

strahlungsquelle, vorzugsweise einen Infrarotstrahler, anzuordnen. Dadurch ist die Möglichkeit gegeben, die Temperatur der in die Ziehform einlaufenden, bereits mit Kunstharz getränkten Rovings den günstigsten Bedingungen anzupassen. Das Harzbad wird durch die einlaufenden, kalten Rovings laufend gekühlt, so dass der Teil des erwärmten Harzes, der von den getränkten Rovings wieder in das Harzbad zurückläuft, keine nennenswerte Rolle spielt, da diese Menge, verglichen mit dem gesamten Volumen des Harzbades, relativ klein ist. Ein weiterer Vorteil der erfindungsgemässen Anordnung besteht darin, dass die Aushärtung mit bereits vorgewärmten, getränkten Rovings wesentlich schneller vor sich geht, so dass ein wesentlich schnellerer Durchlauf der Rovings durch ' das Harzbad erzielt wird, das Harz dadurch schneller verbraucht wird und daher das Harzbad öfter aufgefüllt und erneuert werden muss und somit die Lebensdauer des Bades erhöht wird. 'radiation source, preferably an infrared radiator, to be arranged. This enables the temperature of the already soaked with synthetic resin entering the drawing mold To adapt rovings to the most favorable conditions. The resin bath is running through the incoming, cold rovings cooled, so that the part of the heated resin that runs back into the resin bath from the soaked rovings does not plays a significant role since this amount is relatively small compared to the total volume of the resin bath. A further advantage of the arrangement according to the invention is that the curing process with already preheated, soaked rovings goes on much faster, so that a much faster passage of the rovings through ' the resin bath is achieved, the resin is consumed faster and therefore the resin bath is filled up and more often must be renewed and thus the service life of the bathroom is increased. '

Durch das erfindungsgemässe Verfahren können neben der Erhöhung der Ziehgeschwindigkeit und der besseren Durchtränkung ebenfalls Profile mit höherem Glasgehalt hergestellt werden, wodurch ebenfalls eine Verbesserung der mechanischen und thermischen Eigenschaften erreicht wird.By the method according to the invention, in addition to the increase the drawing speed and the better impregnation, profiles with a higher glass content can also be produced, which also improves the mechanical and thermal properties.
