Abstract
Description
Die Erfindung betrifft ein Verfahren zum Hinterspritzen eines Dekormaterials sowie ein nach dem Verfahren herstellbares Verbundprodukt.The The invention relates to a method for back-molding a decorative material and a composite product that can be produced by the method.
Dekorative Oberflächen, insbesondere von Fahrzeuginnenräumen, werden durch Hinterspritzverfahren hergestellt. Dabei werden Dekormaterialien, beispielsweise Kunststofffolien oder Textilien, in Spritzgießwerkzeugen eingelegt und anschließend mit einer fließfähigen Kunststoffformmasse auf einer von einer Sichtseite abgewandten Seite des Dekormaterials, der Spritzseite, hinterspritzt. Nach Aushärten der Kunststoffformmasse behält das so hergestellte Verbundprodukt seine durch einen Formraum der Spritzgießform vorgegebene äußere Form.Decorative Surfaces, especially of vehicle interiors, are produced by back injection molding. Decorative materials, for example plastic films or textiles, in injection molds inserted and then with a flowable plastic molding compound on a side of the decorative material facing away from a visible side, the spray side, back injection. After the plastic molding compound has hardened reserves the composite product thus produced is formed by a molding space injection mold given outer shape.
Um eine Beschädigung des empfindlichen Dekormaterials durch die heiße Kunststoffformmasse während der Hinterspritzung zu vermeiden, ist bekannt, das Dekormaterial vor der Hinterspritzung auf seiner Spritzseite mit einer Barriereschicht aus Vlies zu kaschieren. Die Vliesschicht verbindet sich beim nachfolgenden Hinterspritzen mit der Kunststoffschicht. Um einen wirksamen Schutz des Dekormaterials beim Hinterspritzen zu gewährleisten, sind relativ hohe Schichtdicken des Vlieses erforderlich. Dies führt zu einem hohen Gewicht und hohen Kosten. Ferner kann die Barriereschicht eine Faltenbildung verursachen, die sich optisch nachteilig auf das Dekormaterial überträgt.Around damage the sensitive decorative material through the hot plastic molding compound during the Avoiding back injection is known to decorate the front the back injection on its spray side with a barrier layer to be laminated from fleece. The fleece layer connects in the following Injection molding with the plastic layer. For effective protection to ensure the decorative material when injecting are relatively high Layer thicknesses of the fleece required. This leads to a high weight and high cost. Furthermore, the barrier layer can form wrinkles cause that visually disadvantageously transferred to the decorative material.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren zum Hinterspritzen eines Dekormaterials bereitzustellen, das zu einem hinterspritzten Verbundprodukt mit möglichst niedrigem Gewicht führt und mit niedrigen Kosten durchführbar ist. Es soll ferner ein entsprechendes Verbundprodukt zur Verfügung gestellt werden.The The invention is therefore based on the object of a method for back injection to provide a decorative material that is back-injected Composite product with as much as possible low weight leads and is feasible at low cost. A corresponding composite product is also to be made available become.
Diese Aufgabe wird durch ein Verfahren mit den Merkmalen des Anspruchs 1 sowie ein Verbundprodukt nach Anspruch 8 gelöst.This Task is achieved by a method with the features of the claim 1 and a composite product according to claim 8 solved.
Erfindungsgemäß wird als Barriereschicht ein Maschen- oder Webwarenmaterial, insbesondere ein Gewebe, ein Gewirke oder ein Gestrick, verwendet. Maschen- oder Webmaterialien haben gegenüber den gemäß der Stand der Technik verwendeten Vliesmaterialien den Vorteil einer höheren Widerstandskraft gegenüber der Kunststoffformmasse. Dies ermöglicht den Einsatz geringerer Schichtdicken, der so genannten Grammatur, der Barriereschicht resultierend in der gewünschten Reduktion von Kosten und Gewicht des Verbundproduktes. Es hat sich zudem als vorteilhaft erwiesen, dass die erfindungsgemäß eingesetzten Maschen- oder Webwarenmaterialien aufgrund ihrer Elastizität kaum zur Faltenbildung infolge der beim Hinterspritzen einwirkenden Scherkräfte neigen.According to the invention is considered Barrier layer a knitted or woven material, in particular a Woven, knitted or knitted fabric. Knitted or woven materials have opposite according to the status fleece materials used in technology have the advantage of a higher resistance across from the plastic molding compound. This enables the use of fewer Layer thicknesses, the so-called grammage, resulting in the barrier layer in the desired one Reduction of costs and weight of the composite product. It has also proven to be advantageous that the used according to the invention Due to their elasticity, knitted or woven materials hardly cause wrinkles due to the shear forces acting during the back injection.
Barriereschichten aus synthetischen Faser (Chemiefaser) haben sich aufgrund der guten Stabilität und der niedrigen Rohstoffpreise als besonders vorteilhaft bewährt. Zudem eignen sie sich zu einem dauerhaften Verschmelzen mit der Kunststoffformmasse.barrier layers made of synthetic fiber (man-made fiber) because of the good stability and the low raw material prices have proven to be particularly advantageous. moreover they are suitable for permanent fusion with the plastic molding compound.
Je nach Verwendung kann die Barriereschicht eine Grammatur von 30 bis 300 g/m2 aufweisen.Depending on the use, the barrier layer can have a grammage of 30 to 300 g / m 2 .
Es ist ferner möglich, das Dekormaterial zunächst auf seiner Spritzseite ganz oder teilflächig mit einer Schaumstoffschicht zu kaschieren, ehe die Kaschierung mit der Barriereschicht erfolgt. Solche mit Schaumstoff unterlegte Dekorformteile sind besonders in Fahrzeuginnenräumen verbreitet.It is also possible the decor material first all or part of its spray side with a foam layer to be laminated before the lamination with the barrier layer takes place. Such molded moldings underlaid with foam are special in vehicle interiors common.
Das erfindungsgemäße Verbundprodukt umfasst eine Dekormaterialschicht mit einer Sicht- und einer Spritzseite, eine spritzseitig angeordnete Barriereschicht aus einem Maschen- und Webwarenmaterial und eine an die Barriereschicht anschließende Kunststoffschicht. Optional kann zwischen der Dekormaterialschicht und der Barriereschicht ganz oder teilflächig eine Schaumstoffschicht angeordnet sein.The Composite product according to the invention includes a decorative material layer with a visible and a spray side, a spray layer arranged on the spray side made of a mesh and woven goods material and a plastic layer adjoining the barrier layer. Optionally, between the decorative material layer and the barrier layer whole or partial a foam layer can be arranged.
Das erfindungsgemäße Verbundmaterial eignet sich besonders vorteilhaft für Fahrzeuginnenverkleidungen, beispielsweise für Säulen-, Seiten- oder Fahrzeugtürverkleidungen.The Composite material according to the invention is suitable themselves particularly advantageous for Vehicle interior linings, for example for pillar, side or vehicle door linings.
Weitere bevorzugte Ausgestaltungen der Erfindung sind Gegenstand der übrigen Unteransprüche.Further preferred embodiments of the invention are the subject of the remaining subclaims.
