Description

Schutzplanenstoff und Verfahren zu dessen HerstellungTarpaulin fabric and process for its manufacture
Die Erfindung betrifft einen wasserdichten, wärmereflektierenden Schutzplanenstoff und ein Verfahren zu dessen Herstellung.The invention relates to a waterproof, heat-reflecting tarpaulin and a method for its production.
Die wasserdichte Ausrüstung von Schwergeweben wird nach dem Stand der Technik in üblicher Weise in Zwei- oder Mehrbadver- fahren durchgeführt, wobei auf der Ware eine wasserunlösliche Metallseife erzeugt wird und die Gewebeporen zusätzlich durch Füllmittel und Paraffin oder Ähnliches geschlossen werden (siehe W. Bernard, "Appretur der Textilien", 2. Auflage 1967, Springer- Verlag, Seiten 326 ff) . Absolut wasserdichte Gewebe erhalt man durch Beschichten, wobei als Beschichtungsmittel u.a. Polyvinyl- chlorid herangezogen wird.According to the state of the art, the waterproofing of heavy fabrics is carried out in a customary manner in two or more bath processes, a water-insoluble metal soap being produced on the goods and the fabric pores additionally being closed by fillers and paraffin or the like (see W. Bernard, "Appretur der Textilien", 2nd edition 1967, Springer-Verlag, pages 326 ff). Absolutely waterproof fabrics can be obtained by coating, where as coating agent i.a. Polyvinyl chloride is used.
Nach diesem Stand der Technik werden ausgerüstete Gewebe mit mindestens 300 g/m2 erhalten. Die daraus hergestellten Abdeckplanen oder Persenninge besitzen ein hohes Gewicht und sind schwer zu verstauen, weisen also allgemein gesagt den Nachteil der umständlichen Handhabung auf.According to this state of the art, finished fabrics with at least 300 g / m2 are obtained. The tarpaulins or tarpaulins made from it have a high weight and are difficult to stow away, so generally speaking they have the disadvantage of cumbersome handling.
Der Erfindung liegt daher die Aufgabe zugrunde, wasserdichte, wärmereflektierende Schutzplanenstoffe zur Verfügung zu stellen, die sich durch ein niedriges Gesamtgewicht auszeichnen.The object of the invention is therefore to provide waterproof, heat-reflecting tarpaulin fabrics which are distinguished by a low overall weight.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß als Grundgewebe ein Polyester-Leichtgewebe von maximal 160 g/m2 einseitig mit mindestens einer pigmenthaltigen Schicht eines vernetzten Polyacrylsäureesters und einer Deckschicht aus Polyurethan, bevorzugt aliphatischem Polyurethan , versehen ist , wobei die Beschichtungen insgesamt 25 bis 80 g/m2 ausmachen. Dementsprechend zeichnet sich das erfindungsgemäße Verfahren zur Herstellung dadurch gekennzeichneter wasserdichter, wärmereflektierender Schutzplanenstoffe dadurch aus, daß auf ein gegebenenfalls vorbehandeltes Polyester-Leichtgewebe von maxiral 160 g/m2 als Grundgewebe einseitig mindestens ein Strich (entsprechend einer Schicht) mittels einer wässrigen, pigmenthaltigen, vernetzbaren Polyacrylsäureesterdispersion und ein Deckstrich mittels eines Polyurethans, bevorzugt aliphatischen Polyurethans, unter Mitverwendung üblicher Hilfsmittel unter Zwischentrocknung aufgebracht wird, wobei während der einzelnen Striche nur soviel an Feststoff aufgebracht wird, daß der fertige Schutzplanenstoff 25 bis 80 g/m2 Feststoffaufläge auf dem Grundgewebe enthält.According to the invention, this object is achieved in that a polyester lightweight fabric of at most 160 g / m 2 is provided on one side with at least one pigment-containing layer of a crosslinked polyacrylic acid ester and a cover layer made of polyurethane, preferably aliphatic polyurethane, the coatings totaling 25 to 80 make up g / m 2 . Accordingly, the process according to the invention for the production of waterproof, heat-reflecting protective tarpaulin fabrics is characterized in that at least one line (corresponding to one layer) by means of an aqueous, pigment-containing, cross-linkable material on an optionally pretreated polyester lightweight fabric of maxiral 160 g / m 2 as base fabric Polyacrylic acid ester dispersion and a top coat using a polyurethane, preferably aliphatic polyurethane, are applied with the use of customary auxiliaries, with intermediate drying, with only enough solid being applied during the individual coats that the finished tarpaulin material contains 25 to 80 g / m 2 solid coatings on the base fabric.
Als Grundgewebe für die erfindungsgemäßen Schutzplanenstoffe hat sich vorzüglich Polyester-Leichtgewebe als geeignet erwiesen, wobei dasselbe auch zusätzlich durch geringe Mengen an Araieidfäden verstärkt sein kann. Unter Leichtgewebe sind dabei solche zu verstehen, deren Quadratmeter-Gewicht zwischen 80 und 160 g, insbesondere zwischen 90 und 120 g, liegt. Besonders oberflächenglatte Schutzplanenstoffe werden erhalten, wenn als Grundgewebe ein leichtes Polyesterfilamentgewebe eingesetzt wird, weshalb diese Gewebeart besonders bevorzugt ist. Polyester lightweight fabric has proven to be particularly suitable as the base fabric for the protective tarpaulin fabrics according to the invention, although the same can also be reinforced by small amounts of araid threads. Lightweight fabrics are to be understood to mean those whose square meter weight is between 80 and 160 g, in particular between 90 and 120 g. Protective tarpaulin fabrics with a particularly smooth surface are obtained if a light polyester filament fabric is used as the base fabric, which is why this type of fabric is particularly preferred.
Die verwendbaren vernetzbaren Polyacrylsäureester sind aus dem Stand der Technik bekannt. Als reaktionsfähige Gruppen enthalten die vernetzbaren Polyacrylsäureester z.B. N-Methylolgruppen, insbesondere Carbonsäureamid-Methylolgruppen. Auch veretherte N-Methylolgruppen, wobei zur Veretherung Alkohole mit ein bis drei C-Atomen, insbesondere Methanol, verwendet wurden, sind als vernetzungsfähige Gruppen geeignet. Die Monomeren, die diese vernetzungsfähigen Gruppen tragen, sind allgemein bekannt. Genannt seien N- Additionsprodukte von Formaldehyd an Methacrylamid bzw. Acrylamid, sowie Allyl- bzw. Methallylcarbamat.The crosslinkable polyacrylic acid esters that can be used are known from the prior art. The crosslinkable polyacrylic acid esters contain as reactive groups e.g. N-methylol groups, especially carboxamide methylol groups. Etherified N-methylol groups, where alcohols containing one to three carbon atoms, in particular methanol, have been used for the etherification, are also suitable as crosslinkable groups. The monomers which carry these crosslinkable groups are generally known. N-addition products of formaldehyde with methacrylamide or acrylamide and allyl or methallyl carbamate may be mentioned.
Auch können die vernetzbaren Polyacrylsäureester als reaktionsfähige Gruppen z.B. Glycidylreste enthalten. Diese Comonomeren sind ebenfalls hinreichend bekannt. Als Beispiel sei Allyglycidylether genannt.The crosslinkable polyacrylic acid esters can also be used as reactive groups e.g. Contain glycidyl residues. These comonomers are also well known. An example is allyglycidyl ether.
Unter dem Begriff vernetzbare Polyacrylsäureester sind außerdem - und diese Gruppe von Copolymeren ist bevorzugt - auch solche zu verstehen , die reaktive Comonomere enthalten , die zur Vernetzung ein geeignetes Härtungs- bzw. Vernetzungsmittel, z.B. übliche Aminoplastharze oder Aminogruppen enthaltende Silane und/oder Siloxane benötigen. Als derartige Comonomere sind beispielsweise solche aufzuführen, die freie OH-Gruppen aufweisen, z.B. 2-Hydroxyethyl- und 3-Hydroxypropylacrylat bzw. -methacrylat. Auch ungesättigte Carbonsäuren, z.B. Acrylsäure und Methacrylsäure und deren Amide führen mit Aminoplastharzen zu vernetzten Polyacrylsäureestern. Letztere werden ganz besonders bevorzugt einpolymerisiert, da diese Schutzplanenstoffe mit diesen Beschichtungen durch ein besonders gutes Gesamtergebnis gekennzeichnet sind.The term crosslinkable polyacrylic acid esters are also - and this group of copolymers is preferred - also to be understood as meaning those which contain reactive comonomers which have a suitable curing or crosslinking agent, e.g. need conventional aminoplast resins or silanes and / or siloxanes containing amino groups. Examples of such comonomers are those which have free OH groups, e.g. 2-hydroxyethyl and 3-hydroxypropyl acrylate or methacrylate. Unsaturated carboxylic acids, e.g. Acrylic acid and methacrylic acid and their amides lead to crosslinked polyacrylic acid esters with aminoplast resins. The latter are very preferably polymerized in, since these protective tarpaulin materials with these coatings are characterized by a particularly good overall result.
Selbstverständlich können die verwendeten Copolymeren auch mehrere der genannten Comonomeren enthalten. Die Mengen an Comonomeren mit vernetzbaren Gruppen liegen bei etwa 1,0 bis 15, insbesondere 2 bis 10 Gew.%, bezogen auf das gesamte Copolymerisat. Die weiterhin in den Polyacrylsäureestern enthaltenen Monomeren sind ebenfalls bekannt. Neben Methacryl- bzw. Acrylsäure- estern z.B. Methacryl- bzw. Acrylsäureestern von Alkoholen mit ein bis acht C-Atomen wie Methanol, Ethanol, Butanol, Isobutanol oder 2-Ethylhexanol, die in der Regel in Mengen von 45 - 99,0 Gew.% bezogen auf das gesamte Polyacrylsäureesterco- polymer isat, enthalten sind, werden bei den verwendeten Polymeren auch andere Comonomere, z.B. Vinylacetat, Ethylen, Styrol, Vinylchlorid und besonders bevorzugt Acrylnitril einpolymerisiert. Diese Comonomeren sind in Mengen bis zu 40 Gew.%,bezogen auf das gesamte Polymerisat, enthalten.Of course, the copolymers used can also contain several of the comonomers mentioned. The amounts of comonomers with crosslinkable groups are about 1.0 to 15, in particular 2 to 10,% by weight, based on the total copolymer. The monomers also contained in the polyacrylic acid esters are also known. In addition to methacrylic or acrylic acid esters, for example methacrylic or acrylic acid esters of alcohols having one to eight carbon atoms, such as methanol, ethanol, butanol, isobutanol or 2-ethylhexanol, which are generally in amounts of 45-99.0% by weight. % based on the total polyacrylic acid ester copolymer is contained, other comonomers, for example vinyl acetate, ethylene, styrene, vinyl chloride and particularly preferably acrylonitrile, are also copolymerized in the polymers used. These comonomers are present in amounts of up to 40% by weight, based on the total polymer.
Die beschriebenen vernetzbaren Polyacrylsäureester kommen in Form von etwa 30 - 70 gew. %igen Dispersionen in den Handel.The crosslinkable polyacrylic acid esters described come in the form of about 30-70% by weight. % dispersions in the trade.
In die vernetzbaren Polyacrylsäureesterdispersionen werden Pigmente. eingemischt, die die Wärmereflexion begünstigen. Als derartige Pigmente kommen vor allem Metallpulver in Betracht. Als Metalle sind beispielsweise Aluminium, Nickel, Silber, Zink und Legierungen wie Messing, Bronze, Aluminium-Bronze und dergleichen zu nennen. Aus wirtschaftlichen Überlegungen werden Aluminium und Aluminium-Bronze bevorzugt. Daneben sind aber auch andere wärmereflektierende Pigmente, z.B. Polyesterflimmer oder Glimmer sehr gut geeignet. Die Menge an Pigment kann in weiten Grenzen variieren. Schon 5 Gew.%,bezogen auf vernetzten Polyacrylsäureester, zeigen eine deutliche Wirkung. Bevorzugt sind 8 - 30 Gew.%, besonders bevorzugt 10 - 25 Gew.%, bezogen auf vernetzten Polyacrylsäureester, enthalten. Die obere Grenze wird durch wirtschaftliche Überlegungen, aber auch durch abnehmende Haftung und Reibechtheit des Polymerfilms bestimmt und liegt bei etwa 60 Gew.%, bezogen auf vernetzten Polyacrylsäureester. Wird mit zwei oder mehr Strichen aus vernetzbarem Polyacrylsäureester gearbeitet, so hat es sich bewährt, beim ersten Strich nur eine geringe Menge an Pigment, etwa ein Viertel bis ein Drittel der Gesamtpigmentmenge, einzumischen und die überwiegende Menge an Pigment in den zweiten und weiteren Strich einzuarbeiten, da dadurch die Haftung des Filmes wesentlich verbessert wird. Es ist dabei aber auch möglich, in dem ersten Strich auf den Pigmentzusatz ganz zu verzichten, doch ist diese Arbeitsweise weniger geeignet.Pigments are incorporated into the crosslinkable polyacrylic acid ester dispersions. mixed in, which favor the heat reflection. Metal powders are particularly suitable as such pigments. Examples of metals that can be mentioned are aluminum, nickel, silver, zinc and alloys such as brass, bronze, aluminum-bronze and the like. Aluminum and aluminum-bronze are preferred for economic reasons. In addition, other heat-reflecting pigments, such as polyester flicker or mica, are also very suitable. The amount of pigment can vary within wide limits. Already 5% by weight, based on cross-linked polyacrylic acid esters, has a clear effect. It preferably contains 8-30% by weight, particularly preferably 10-25% by weight, based on crosslinked polyacrylic acid esters. The upper limit is determined by economic considerations, but also by decreasing adhesion and fastness to rubbing of the polymer film, and is approximately 60% by weight, based on crosslinked polyacrylic acid esters. If two or more coats of crosslinkable polyacrylic acid ester are used, it has proven useful to mix only a small amount of pigment, about a quarter to a third of the total amount of pigment, with the first coat and the majority of pigment into the second and add another line, as this significantly improves the film's adhesion. However, it is also possible to do without the pigment addition in the first stroke, but this method of working is less suitable.
Auch die für den Deckstrich verwendete Polyurethane gehören zum Stand der Technik. Es erübrigt sich deshalb ein näheres Eingehen auf diese Verbindungen. Besonders geeignet sind die alipathischen Polyurethane, da dieselben eine verbesserte Lichtechtheit aufweisen. Der Deckstrich kann dabei wahlweise aus wässrigem oder organischem Medium erfolgen. Die rohen Polyesterleichtgewebe werden in bekannter Weise gewaschen und dann gegebenenfalls wie üblich vorbehandelt. Durch die Vorbehandlung wird die Filmhaftung etwas verbessert.The polyurethanes used for the top coat also belong to the prior art. It is therefore not necessary to go into these connections in more detail. The aliphatic polyurethanes are particularly suitable because they have improved light fastness. The top coat can be done either from an aqueous or organic medium. The raw polyester lightweight fabrics are washed in a known manner and then optionally pretreated as usual. Pretreatment improves film adhesion somewhat.
Die Beschichtung selbst wird ebenfalls in bekannter Weise vorgenommen. Dazu wird das leichte Polyestergrundgewebe einseitig mit mindestens einem Strich des pigmenthaltigen Polyacrylsäureesters beschichtet und zwischengetrocknet. Besonders bevorzugt wird mit zwei Polyacrylsäureester-Schichten gearbeitet, wobei die geforderten geringen Auflagemengen bevorzugt mittels Luftrakel appliziert werden. Anschließend wird das Polyurethan als Deckstrich, ebenfalls vorzugsweise mit einer Luftrakel, aufgebracht (nähere .Einzelheiten siehe Beispiele). Bei der Applikation werden selbstverständlich die üblichen Hilfsmittel wie Vernetzungsmittel, Verdickungsmittel, pH-Regulatoren usw. mitverwendet. Auch der gleichzeitige Einsatz von üblichen Aminoplastharzen, Hydrophobiermitteln, Farbpigmenten und ähnlichen ist ohne weiteres möglich und von Fall zu Fall durchaus auch zweckmäßig und vorteilhaft. Die Mengen an derartigen Zusatzstoffen sind dem Fachmann geläufig.The coating itself is also carried out in a known manner. For this purpose, the light polyester base fabric is coated on one side with at least one coat of the pigment-containing polyacrylic acid ester and dried in between. It is particularly preferred to work with two layers of polyacrylic acid ester, the small amounts required being applied preferably by means of an air knife. The polyurethane is then applied as a top coat, also preferably with an air knife (for further details, see examples). Of course, the usual auxiliaries such as crosslinking agents, thickeners, pH regulators, etc. are also used in the application. The simultaneous use of conventional aminoplast resins, water repellents, color pigments and the like is also readily possible and is also expedient and advantageous from case to case. The amounts of such additives are known to the person skilled in the art.
In der beschriebenen Weise wird ein Schutzplanenstoff erhalten, der sich gegenüber den bekannten Produkten durch beachtliche, überraschende Vorteile auszeichnet. Es war nämlich aufgrund des Standes der Technik nicht zu erwarten, daß es gelingt, einen so leichten und trotzdem mechanisch festen Schutzplanenstoff her zustellen. Besonders das verwendete spezielle Grundgewebe und der Zusatz der wärmereflektierenden Pigmente zu den vernetzbaren Polyacrylsäureestern gestattet es, in so einfacher Weise die vorteilhaften Schutzplanenstoffe zu fertigen. Dieser zeichnet sich nicht nur durch eine hohe Festigkeit und das geringe Gewicht auf, sondern läßt auch hinsichtlich der Wasserdichtigkeit und Wärmereflexion keine Wünsche offen. Die daraus hergestellten Artikel, insbesondere Persenninge, gestatten einfache Handhabung und sind daher problemlos zu verwenden.In the manner described, a protective tarpaulin material is obtained which is distinguished from the known products by remarkable, surprising advantages. Because of the state of the art it was not to be expected that such a light yet mechanically strong protective tarpaulin material would be possible to deliver. In particular, the special base fabric used and the addition of the heat-reflecting pigments to the crosslinkable polyacrylic acid esters make it possible to manufacture the advantageous tarpaulin fabrics in a simple manner. This is not only characterized by its high strength and low weight, but also leaves nothing to be desired in terms of water resistance and heat reflection. The articles made from it, especially tarpaulins, allow easy handling and are therefore easy to use.
