B. zur Abdichtung von Dehn- und Anschlußfugen im Bauwesen, zur Randabdichtung von Isolierglasscheiben, zur Glasfalzversiegelung und zur Verklebung verschiedener Materialien im Maschinenbau werden hauptsächlich auf einer Harzbasis von Polysulfiden, Siliconen, Polyurethanen, aber auch aus anderen Harzen wie z. B. Acrylpolymerisaten (Co- und Terpolymerisaten) oder deren Gemischen hergestellt.Elastic sealants and adhesives, e.g. B. for sealing expansion and connection joints in construction, for sealing the edges of insulating glass panes, for sealing glass rabbets and for bonding various materials in mechanical engineering are mainly on a resin basis of polysulfides, silicones, polyurethanes, but also from other resins such. B. Acrylic polymers (co- and terpolymers) or their mixtures are produced.

Bei derartigen Produkten wurde die Elastizität der Dichtungsmassen und Klebwerkstoffe durch Zugabe erhöhter Mengen mn Weichmachern herabgesetzt, so daß die Untergrundhaftung erhöht und die Rißbildung innerhalb der elastischen Masse verringert wurde. Diese Massen besitzen ihrerseits allerdings die Nachteile, daß sie Weichmacher an die umgebenden Werkstoffe abgeben und zur permanenten Klebrigkeit neigen, womit eine erhöhte Verschmutzungsanfälligkeit verbunden ist.had been, various attempts to improve quality were carried out and products, at to which the cohesive forces were deliberately lowered. With such products, the Elasticity of sealing compounds and adhesives due to the addition of increased amounts of plasticizers reduced, so that the substrate adhesion increases and the formation of cracks within the elastic mass was reduced. However, these masses in turn have the disadvantages that they plasticizers to the surrounding materials and tend to be permanently sticky, which increases the susceptibility to soiling connected is.
Es wurde nun gefunden, daß durch elastische Dichtungsmassen und Klebwerkstoffe gemäß der Erfindung die genannten Nachteile weitgehend vermieden werden und Produkte mit sehr guten anwendungstechnischen Eigenschaften, insbesondere deutlich verbesserten Haftungseigenschaften, geringerer Neigung zur Rißbildung und einwandfreier Produktionsmöglichkeit resultieren.It has now been found that elastic sealants and adhesives according to the Invention, the disadvantages mentioned are largely avoided and products with very good application technology Properties, in particular significantly improved adhesion properties, lower tendency result in crack formation and flawless production possibility.

Die verwendeten Polyäthylen- und Polypropylenpulver liegen vorzugsweise in den erfindungsgemäßen elastischen Dichtungsmassen und Klebwerkstoffen in einem Verteilungsgrad von 0 bis 200 μ, insbesondere von 0 bis 50 μ vor. Als Polyäthylen kommt Hoch- sowie Niederdruckpolyäthylen in Frage, wobei letzteres bevorzugt istThe polyethylene and polypropylene powders used are preferably those according to the invention elastic sealing compounds and adhesives in a degree of distribution of 0 to 200 μ, in particular from 0 to 50 μ before. High-pressure and low-pressure polyethylene can be used as polyethylene, the latter being the case is preferred
Bei Konzentrationen oberhalb 40 Gew.-% treten bei permanenter, dynamischer Beanspruchung Ermüdungserscheinungen im Material auf. Unterhalb von 1 is Gew.-% sind die vorstehend beschriebenen Vorteile nicht vorhanden. Ein bevorzugter Bereich ist 5 bis 30, insbesondere 15 bis 20 Gew.-%.At concentrations above 40% by weight, permanent dynamic loading causes fatigue in the material. Below 1% by weight are the advantages described above unavailable. A preferred range is 5 to 30, in particular 15 to 20% by weight.
Feinvereeilte Polyäthylenwachse wurden bisher z. B. in Lacken und Druckfarben zur Erzielung von Matteffekten, zur Verbesserung der Partikelverteilung, zur Viskositätssteigerung und zur Vermeidung der Sedimentation eingesetzt (siehe hierzu Farbe und Lack/82. Jahrgang/Nr. 11/1976).Finely divided polyethylene waxes were previously z. B. in paints and printing inks to achieve matt effects, to improve particle distribution, used to increase viscosity and to avoid sedimentation (see color and Paint / 82. Year / No. 11/1976).
Die Verwendung von feinverteiltem Polyäthylen- und/oder Polypropylenpulver zur Herstellung der speziellen elastischen Dichtungsmassen und Klebwerkstoffe ist auch nicht aus der FR-PS 15 14 532 und den DE-OS 19 41059 und 23 09508 zu entnehmen, die andere Massen bzw. andere Verwendungen betreffen.The use of finely divided polyethylene and / or polypropylene powder to produce the special elastic sealants and adhesives is not from FR-PS 15 14 532 and the DE-OS 19 41059 and 23 09 508 can be found, which relate to other materials or other uses.
Der wesentliche Vorteil der erfindungsgemäßen Dichtungsmassen und Klebwerkstoffe besteht darin, daß die mit ihnen aufgezeichneten Kraft-Längenänderungs-Diagramme nach DIN 53 455 in allen Fällen einen deutlich flacheren Kurvenverlauf ergeben. Es sind i> folglich bei allen Längenänderungen (Dehnungen) geringere Kräfte aufzuwenden; die Kohäsionskräfte werden erniedrigt und die Spannungen auf die Fugenflanken bzw. anderen Untergründe werden abgebautThe main advantage of the sealing compounds and adhesive materials according to the invention is that the force-elongation diagrams recorded with them according to DIN 53 455 in all cases result in a significantly flatter curve. There are i> consequently use less forces for all length changes (expansions); the cohesive forces are lowered and the tensions on the joint flanks or other substrates are reduced reduced
Die praktische Konsequenz dieses meßbaren Effekts ist eine deutlich geringere Häufigkeit eines Adhäsionsoder Kohäsionsfehlers. Darüber hinaus werden die oben aufgeführten Nachteile eliminiert, die sich dadurch ergeben, daß sich bei der Produktion elastischer Dichtungsmassen und Klebwerkstoffe die eingesetzten Füllstoffe nicht völlig aufschließen lassen. Der unvollständige Aufschluß kann insbesondere dann zwangsläufig eintreten, wenn eine bestimmte Prozeßführung, bei der z. B. die Einwirkung hoher Scherkräfte vermieden werden muß, unumgänglich ist. Die mit Polyäthylen- und/oder Polypropylenpulvern hergestellten elastischen Dichtungsmassen und Klebwerkstoffe sind auch unter ungünstigen Produktionsbedingungen völlig homogen.The practical consequence of this measurable effect is a significantly lower frequency of an adhesion or cohesion failure. In addition, the above will be Eliminated listed disadvantages, which result from the fact that in the production more elastic Sealing compounds and adhesives do not allow the fillers used to fully break down. The incomplete one In particular, digestion can inevitably occur when a certain process is conducted the z. B. the action of high shear forces must be avoided is inevitable. The polyethylene Elastic sealants and adhesives made from polypropylene powders and / or polypropylene powders are also included completely homogeneous under unfavorable production conditions.
Die in den erfindungsgemäßen Dichtungsmassen und Klebwerkstoffen enthaltenen feinverteilten Polyäthylen- oder Polypropylenpulver müssen selbstverständlich auch mit den übrigen Bestandteilen der Formulierung, wie z. B. mit Weichmachern, Füllstoffen, Katalysatoren, Pigmenten, Stabilisatoren usw. verträglich sein. Den Bindemitteln gegenüber sind sie chemisch inert, d. h, sie gehen mit ihnen keine chemischen Wechselwirkungen ein.The finely divided polyethylene contained in the sealing compounds and adhesive materials according to the invention or polypropylene powder must of course also with the other ingredients of the formulation, such as B. be compatible with plasticizers, fillers, catalysts, pigments, stabilizers, etc. The They are chemically inert to binders, i. h, they have no chemical interactions with them a.
