Abstract

Polyolefin moulded components esp. filled polypropylene components, are adhesively bonded together with the aid of polyurethane elastomer, by applying a polyurethane-based 2-component adhesive onto the pre-treated surface of the adherents. The adhesive comprises (A) a branched polyester alcohol, admixed with an accelerator and a water-binding medium, and, (B) a polyisocyanate. The ratio of OH-gps. in (A): isocyanate-gps. in (B) = 0.8-1.2. After the elastomer layer has been applied it is st and cured. The adhesive is used in the assembly by adhesive bonding of ventilation components for motor vehicles. Polyolfin mouldings that have been bonded together by the process will tolerate a broad range of temp. changs in use e.g. -40 to +120 dgrees C, without loss of elasticity.

Description

Verfahren zum Verbinden von Formteilen aus Polyolefinen mit einer Elastomerschicht Die Erfindung betrifft ein Verfahren zum Verbinden von Formteilen aus Polyolefinen mit einer Elastomerschicht insbesondere von Formteilen komplizierter Geometrie aus gefülltem Polypropylen mit einer Schicht aus Polyurethan.Process for connecting molded parts made of polyolefins with a Elastomer layer The invention relates to a method for connecting molded parts made of polyolefins with an elastomer layer, in particular molded parts more complicated Geometry made of filled polypropylene with a layer of polyurethane.

So zusammengesetzte Bauteile sind wichtig in der Autoindustrie z.B. für Süftungssysteme.Components assembled in this way are important in the automotive industry, e.g. for ventilation systems.

Bekanntlich sind die Polyolefine schwer zu verkleben, da ihre Oberflächenenergie gering ist. Die zu verklebenden Oberflächen aus Polyolefinen werden daher vor der Verklebung mit Chromsäure Halogenen, durch Beflammen mit einer nichtleuchtenden Gasflamme oder durch Ozon im status nascendi (Glimmentladung) vorbehandelt, wodurch ihre Oberfläche chemisch verändert wird und unter anderem oxidierte Strukturelemente entstehen. Hierdurch wird die Haftfestigkeit gesteigert und die Wärmefestigkeit erhöht.It is well known that polyolefins are difficult to bond because of their surface energy is low. The surfaces to be bonded made of polyolefins are therefore before the Gluing with chromic acid halogens by applying a flame to a non-luminous one Gas flame or pretreated by ozone in the status nascendi (glow discharge), whereby their surface is chemically changed and among other things oxidized structural elements develop. This increases the adhesive strength and the heat resistance elevated.

Für viele Anwendungsgebiete ist eine Temperaturbeständigkeit bei gleichzeitigem Beibehalten der Elastizität erforderlich, insbesondere im Temperaturbereich von -40 bis +1200C. Dies ist mit den herkömmlichen Verklebungen nur schwer zu erreichen.For many areas of application is a temperature resistance at the same time It is necessary to maintain elasticity, especially in the temperature range of -40 to + 1200C. This is difficult to achieve with conventional gluing.

Aufgabe der Erfindung ist die Herstellung von Verklebungen bei Formteilen aus Polyolefin, insbesondere gefülltem Polypropylen mit einer Elastomerschicht, welche die Elastizität bei dem angeführten Temperaturwechselspiel beibehalten.The object of the invention is to produce bonds in molded parts made of polyolefin, in particular filled polypropylene with an elastomer layer, which maintain the elasticity with the stated temperature cycle.

Die Aufgabe wird gemäß der Erfindung dadurch gelöst, daß auf die vorbehandelte Oberfläche des Formteiles aus einem Polyolefin ein Zweikomponentenkleber auf Basis Polyurethan aufgetragen wird, wobei die eine Komponente (A) aus einem verzweigten Polyesteralkohol, versetzt mit einem Beschleuniger und einem wasserbindenden Mittel besteht und die andere Komponente (B) aus einem Polyisocyanat, wobei das Verhältnis der Hydroxylgruppen in (A) zu den Isocyanatgruppen in (B) 0,8 bis 1,2 ist. Die Elastomerschicht wird aufgelegt, fixiert und anschließend ausgehärtet. Vorzugsweise werden die Isocyanatgruppen im Überschuß eingesetzt, damit eine Reaktion mit den oxidierten Strukturelementen der vorbehandelten Polyolefinoberfläche stattfindet. Als bevorzugte Vorbehandlung hat sich Beflammen mit einer nichtleuchtenden Gasflamme erwiesen.The object is achieved according to the invention in that on the pretreated Surface of the molded part made of a polyolefin based on a two-component adhesive Polyurethane is applied, the one component (A) consisting of a branched Polyester alcohol, mixed with an accelerator and a water-binding agent and the other component (B) consists of a polyisocyanate, where the ratio the hydroxyl groups in (A) to the isocyanate groups in (B) is 0.8 to 1.2. The elastomer layer is applied, fixed and then hardened. The isocyanate groups are preferred used in excess, so that a reaction with the oxidized structural elements the pretreated polyolefin surface takes place. As a preferred pre-treatment has been shown to be exposed to a non-luminous gas flame.

Bei Durchführung des erfindungsgemäßen Verfahrens und Verwendung des beanspruchten Klebers erreicht man bei ausreichenden Verarbeitungszeiten kurze Härtungszeiten.When carrying out the method according to the invention and using the stressed adhesive, short curing times can be achieved with sufficient processing times.

Selbst bei talkumgefüllten Polyolefinteilen können noch dauerhafte Verklebungen ereicht werden. Es können nach dem erfindungsgemäßen Verfahren unterschiedlich dicke Klebfuge überbrückt werden. In der Klebschicht tritt zwischen -40 und +1200C kein Bruch ein.Even with talc-filled polyolefin parts, permanent Bondings can be achieved. It can be different according to the method according to the invention thick adhesive joint can be bridged. In the adhesive layer occurs between -40 and + 1200C no break one.

Als Beschleuniger sind organische Metallverbindungen, wie z.B. Phenylquecksilberacetat, Dibutylzinndilaurat, geeignet, durch deren Zugabe und Menge sich die Verarbeitungszeit und Härtungszeit in weiten Grenzen variieren lassen.Organic metal compounds such as phenyl mercury acetate, Dibutyltin dilaurate, suitable, the addition and quantity of which increases the processing time and curing time can be varied within wide limits.

Die Härtungszeit läßt sich bei Raumtemperatur von ca. einer Stunde bis auf wenige Sekunden reduzieren. Bei Härtung in der Wärme kann man den Vorteil einer längeren Verarbeitungszeit mit dem einer kurzen Härtungszeit kombinieren.The curing time can be about one hour at room temperature reduce to a few seconds. When hardening in heat one can get the advantage combine a longer processing time with that of a short hardening time.

Das erfindungsgemäße Verfahren eignet sich zum Verkleben von Elastomeren mit Polyolefinen. Solche Verklebungen sind von Interesse für Körperschalldämmung in Lüftungssystemen von Kraftfahrzeugen, insbesondere für Wasserabweiser, Heizungsgehäuse, Verteiler u. dgl.The method according to the invention is suitable for bonding elastomers with polyolefins. Such bonds are of interest for structure-borne sound insulation in ventilation systems of motor vehicles, in particular for water deflectors, heating housings, Distributor and the like
