Abstract

Method and production of a self-adhesive, elastic and open-pored substrate, in particular a foam, equipped with a dimension-stabilising support, characterised in that the substrate is coated in one operation simultaneously with the support and with the adhesive by the transfer method. <IMAGE>

Description

Die Erfindung betrifft ein Transferverfahren zur Her­ stellung selbstklebender, elastischer und offenporiger Schäume, die mit einem dimensions­ stabilisierenden Träger ausgerüstet sind.The invention relates to a transfer method to the Her position self-adhesive, elastic and open-pored Foams with a dimensions stabilizing carriers are equipped.

Mit Selbstklebemassen beschichtete und mit einem Träger versehene Schäume sind in der Industrie wie in Privathaus­ halten weit verbreitet und werden unter anderem zu Zwecken der Abdichtung sowie zur Dämpfung von Dröhn- und Klapper­ geräuschen eingesetzt. Hierbei erhöht der Träger die me­ chanische Stabilität, erhält die Dimensionen bei Verarbei­ tung und Anwendung, und erleichtert die Wiederaufnahme. Andererseits kann er die Einreißbarkeit bei der Verarbei­ tung erschweren und sogar verhindern.Coated with self-adhesive and with a carrier provided foams are in industry as in private homes hold widespread and are used among other things for purposes the sealing as well as the damping of booming and rattling noises used. Here, the carrier increases the me chanic stability, maintains the dimensions during processing and application, and facilitates resumption. On the other hand, he can tear the processing difficult and even prevent.

Zur Herstellung solcher Produkte ist es bekannt, eine Klebemasse mit Lösungsmittelzusatz auf einen Träger auszu­ streichen und einen Schaum naß zu laminieren. Gleichzeitig oder in einem späteren Arbeitsgang wird die Trägerrück­ seite mit Klebmasse versehen und dann das Lösungsmittel in Trockenkanälen abgedunstet. Durch Eindeckung mit Trennpa­ pier beim Aufwickeln zur Rolle wird die Schaumrückseite vor Verklebung geschützt. It is known to produce such products, a Adhesive with solvent added on a carrier paint and wet laminate a foam. At the same time or in a later step, the carrier back side with adhesive and then the solvent in Drying channels evaporated. By covering with separation pa The foam backing becomes a roll when it is rolled up protected from gluing.  

Solche Verfahren bedingen bei der industriellen Her­ stellung jedoch einen hohen Energieeinsatz, um das ein­ gesetzte Lösungsmittel aus dem Schaum und der aufgetra­ genen Schicht zu verdampfen. Weiterhin sind aufwendige Trocknungsanlagen notwendig, um die zur Erzielung eines ausreichenden Verbundes notwendigen hohen Masseaufträge unter Erzielung ökonomischer Bandgeschwindigkeiten zur realisieren.Such processes are necessary in industrial manufacturing position, however, a high energy input in order to achieve this put solvent from the foam and the applied evaporate layer. Furthermore, they are complex Drying equipment necessary to achieve a sufficient network necessary high bulk orders while achieving economical belt speeds for realize.

Weitere Verfahren zur Beschichtung der genannten Sub­ strate mit lösungsmittelfreien Schmelzhaftklebern sind bekannt und bedingen gleichfalls hohe Masseaufträge zur Erzielung ausreichender Verbundfestigkeiten. Die verwen­ deten Träger müssen in gewissem Grade unempfindlich gegen Temperatur und Überdehnung sein, und Spannungen beim Auf­ trag erschweren eine gleichmäßige Produktqualität.Other methods for coating the sub strate with solvent-free hot melt pressure sensitive adhesives known and also require high volume orders for Achieving sufficient bond strengths. They use The wearer must be somewhat insensitive to Temperature and overexpansion, and tension when opening uniform product quality complicate.

Ziel der Erfindung war es daher, ein ökonomisch und ökologisch vorteilhaftes Verfahren sowie einen darauf abgestimmten Produktaufbau zu entwickeln, um insbesondere Leichtschäume unter Erreichung von Wiederaufnehmbarkeit, guten Verbundfestigkeiten und Dimensionsstabilität ggf. bei gleichzeitiger Einsparung der Eindeckung selbstklebend auszurüsten.The aim of the invention was therefore an economical and ecologically advantageous process and one on it to develop coordinated product structure, in particular Lightweight foams with the aim of achieving re-absorption, good bond strengths and dimensional stability if necessary self-adhesive while saving the covering equip.

Gelöst wird dieses Ziel mit einem Verfahren, wie dies in den Patentansprüchen näher gekennzeichnet ist.This goal is achieved with a procedure like this is characterized in more detail in the claims.

Durch vorteilhafte Ausrüstung der Schaumrückseite mit einer Release-Beschichtung auf Dispersionsbasis kann auf eine trennende Eindeckung verzichtet werden. Die Beschich­ tung erfolgt mittels geeigneter Auftragsverfahren wie Walzenauftragswerk oder rotativer Siebdruck, die Trocknung wird thermisch oder über geeignete elektromagnetische Systeme durchgeführt. Hierdurch kann auf den Einsatz organischer Lösungsmittel ebenso verzichtet werden wie auf kostenintensive Explosionsschutz-Vorsorgemaßnahmen. Bei sorgfältiger Abstimmung der Beschichtungsparameter (Be­ schichtungs- und Kaschiertemperaturen, Flächengewicht, etc.), und der Rezeptur der Klebemasse auf das eingesetzte Schaummaterial kann auch gänzlich auf eine Release-Be­ schichtung ohne Produktnachteil verzichtet werden.Thanks to the advantageous equipment of the foam back with a release coating based on a dispersion can separating roofing can be dispensed with. The Beschich processing is carried out using a suitable application process such as Roller applicator or rotary screen printing, drying is thermal or via suitable electromagnetic Systems implemented. This can be used  organic solvents as well as Preventive explosion protection measures. At careful coordination of the coating parameters (Be layering and laminating temperatures, basis weight, etc.), and the formulation of the adhesive on the used Foam material can also be used entirely on a release layering without product disadvantage.

Die Aufgabenstellung der selbstklebenden Beschichtung wird vorteilhaft derart gelöst, daß auf ein speziell prä­ pariertes, endloses Band ("Gurtband") ein offenes Gewebe oder dergleichen als Träger aufgelegt und mittels Schmelz­ kleber-Beschichtungsaggregat die Klebemasse aufgetragen wird. Durch einen geeigneten Anlagenaufbau wird dabei sichergestellt, daß sich ein bestimmter Teil des Klebers oberhalb, der andere Teil unterhalb des Trägers (Gewebe oder dergleichen), befindet. Dieser Verbund wird dann in einem Transferverfahren vollständig auf einen ggf. ausge­ rüsteten Schaumträger übertragen.The task of the self-adhesive coating is advantageously solved in such a way that on a special pre parried, endless band ("webbing") an open fabric or the like applied as a carrier and by means of melting adhesive coating unit applied the adhesive becomes. With a suitable system structure ensures that a certain part of the adhesive above, the other part below the carrier (tissue or the like). This association is then in a transfer procedure completely to a possibly equipped foam carrier transferred.

Die räumliche Trennung von Beschichtungs- und Transfer­ station erlaubt es, die Übertragungstemperatur und -vis­ kosität den Substrat- und Produkterfordernissen anzupassen und hinsichtlich Verbundfestigkeit von Trägern, Schmelzhaftkleber und Schaum zu beeinflus­ sen. Eine Temperierung am Transferpunkt, z. B. durch Ein­ satz von Heiz- oder Kühlwalzen, eröffnet weitere Möglich­ keiten zur Prozeßsteuerung.The spatial separation of coating and transfer station allows the transmission temperature and -vis adapt the viscosity to the substrate and product requirements and regarding the bond strength of beams, Hot melt pressure sensitive adhesive and foam sen. A temperature control at the transfer point, e.g. B. by a set of heating or cooling rollers, opens up further possibilities process control.

Die beschriebene Verbundfestigkeit kann ebenfalls noch durch freie Wahl eines Kaschierdrucks im Transferprozeß gesteigert werden.The described bond strength can also still through free choice of a lamination print in the transfer process be increased.

Durch dieses indirekte Beschichtungsverfahren ist eine weitgehend spannungsfreie Verarbeitung elastischer Schaummaterialien ohne erhöhten technischen Aufwand möglich.This indirect coating process is one largely tension-free processing elastic  Foam materials without raised technical effort possible.

Der Bereich der Masseaufträge kann mittels geeigneter, kompakter Beschichtungsaggregate in einem weiten Bereich variiert werden, unter Erzielung ökonomischer Bandge­ schwindigkeiten.The area of bulk orders can be compact coating units in a wide range can be varied, achieving economic bandge speed.

Im folgenden wird die Erfindung bespielhaft erläutert, ohne diese dadurch unnötig einschränken zu wollen.The invention is explained by way of example below. without wanting to restrict them unnecessarily.
