Abstract

In the method for coating mineral whole fiber articles, using a binder, particularly for fire proof, sound, and thermal insulation in the building and construction industry, the articles are coated with the mineral whole fibers and the binder, mixed with water; the binder is comprised of an aqueous plastic material dispersion and/or a solution, for example, a dispersion of homopolymers based on vinyl acetate, copolymers of vinyl acetate and ethylen, vinyl chloride, maleic acid dibutyl ester, acrylic acid ester, versatic acid vinyl ester and/or copolymers based on styrol/ester of acrylic acid, with the optional addition of a fire proof agent.

Description

Verfahren zum Beschichten von Gegenständen Process for coating objects
Die Erfindung betrifft ein Verfahren zum Beschichten von Gegenständen mit Mineralwollefasern unter Verwendung eines Bindemittels, insbesondere zur Wärmedämmung, Schalldämmung und zum Flammfestmachen in der Bautenindustrie.The invention relates to a method for coating objects with mineral wool fibers using a binder, in particular for thermal insulation, sound insulation and flame retardancy in the building industry.
Es ist bereits bekannt, zu diesem Zwecke Flächen an Ge¬ bäuden, Rohren, Trägern usw. mit einem verdüsten Gemisch aus Mineralwollefasern, z.B. Hüttenwolle, die mit einem hydrau¬ lischen Bindemittel, wie Gips, Magnesit oder Zement versetzt worden waren, und Wasser, etwa im Gewichtsverhältnis 1:1 zu beschichten, aus dem nach Verdampfen des Wassers und Abbinden des Bindemittels harte Überzüge entstehen.For this purpose, it is already known to use surfaces on buildings, pipes, beams, etc. with an atomized mixture of mineral wool fibers, e.g. Metallic wool, which had been mixed with a hydraulic binder, such as gypsum, magnesite or cement, and water, approximately in a weight ratio of 1: 1, from which hard coatings are formed after the water has evaporated and the binder has set.
Wesentliche Nachteile dieser Beschichtungen sind dabei u.a. die Unmöglichkeit, dickere Schichten als etwa 4 cm in einem Arbeitsgang aufzutragen, sowie die Unverwendbarkeit zur Be¬ schichtung von z.B. Aluminium- oder verzinkten Bauteilen in¬ folge der auftretenden Korrosion durch die chemische Reaktion mit dem hydraulischen Bindemittel in Anwesenheit von Wasser.The main disadvantages of these coatings include the impossibility of applying layers thicker than about 4 cm in one operation, and the inapplicability for coating e.g. Aluminum or galvanized components as a result of the corrosion occurring due to the chemical reaction with the hydraulic binder in the presence of water.
Es bestand die Aufgabe, ein Beschichtungsverfahren der ge¬ nannten Art zu schaffen, das insbesondere für Oberflächen, die alkalische Bindemittel nicht vertragen, geeignet ist und den Auftrag von dicken Schichten, etwa bis zu einer Dicke von 20 cm, in einem Arbeitsgang gestattet.The object was to create a coating method of the type mentioned which is particularly suitable for surfaces which do not tolerate alkaline binders and which permits the application of thick layers, for example up to a thickness of 20 cm, in one operation.
OMPIOMPI
/,, W1PO ,J Diese Aufgabe wird erfindungsgemäß vor allem dadurch ge¬ löst, daß als Bindemittel eine wässerige Kunststoffdisper¬ sion und/oder Lösung, gegebenenfalls zusammen mit einem Flammfestmacher, eingesetzt wird./ ,, W1PO, J This object is achieved according to the invention in particular in that an aqueous plastic dispersion and / or solution, optionally together with a flame retardant, is used as the binder.
Als besonders günstig haben sich Dispersionen auf Basis von Homopolymerisaten auf Basis von Vinylacetat, Copolymeri- saten aus Vinylacetat und Äthylen, Vinylchlorid, Maleinsäu- redibutylester, Acrylsäureester, Versaticsäurevinylester und/oder Copolymerisaten auf Basis St rol/Acrylsäureester erwiesen.Dispersions based on homopolymers based on vinyl acetate, copolymers made of vinyl acetate and ethylene, vinyl chloride, maleic acid dibutyl ester, acrylic acid esters, vinyl versatic acid and / or copolymers based on stole / acrylic acid esters have proven to be particularly favorable.
Verwendet man als Mineralfaser Hütten- oder Steinwolle, hat sich herausgestellt, daß trotz Verwendung von Kunststof¬ fen als Bindemittel ausgezeichnete Flammschutzwirkung erziel wird, wobei der Kunststoffanteil der Beschichtung lediglich oberflächlich verkohlt, aber nicht brennt oder glimmt, und die Beschichtung nach dem Flammversuch im Ofen lediglich oberflächlich zusammengesintert erscheint. Glasfasern ergebe wegen ihres niedrigen Sinterpunktes keinen Brändschutz. Gege benenfalls können flammhemmende Kunststoffe als Bindemittel eingesetzt oder dem Kunststoff und/oder der Mineralwolle ge¬ eignete Flammhemmer zugesetzt werden.If mineral or rock wool is used as the mineral fiber, it has been found that, despite the use of plastics as a binder, excellent flame retardancy is achieved, the plastic portion of the coating only charring on the surface but not burning or smoldering, and the coating after the flame test in the oven appears only sintered superficially. Because of their low sintering point, glass fibers do not provide fire protection. If necessary, flame-retardant plastics can be used as binders or suitable flame retardants can be added to the plastic and / or mineral wool.
Die Erfindung wird nachstehend an Hand eines Beispiels näher beschrieben: Eine wässerige Kunststoffdispersion z.B. Mowilith (Hoechst) wird z.B. im Verhältnis 1:20 mit Wasser verdünnt sowie pro Liter unverdünnter Dispersion 1,5 g Bo¬ rax als Flammhemmer und gegebenenfalls 1 g Mergal AF als Desinfektionsmittel zugegeben. Die wässerige Dispersion wird etwa im Gewichtsverhältnis 1:1 mit Stein- bzw. Hütten¬ wolle auf die verschiedensten Oberflächen aufgedüst. Ver¬ suche wurden durchgeführt bei Eisenflächen, verzinkten Ei- senflachen, Aluminiumflächen, Eternit, Holz, Ziegelmauer¬ werk sowie Beton mit einer Auftragsstärke bis 20 cm in ei¬ nem Arbeitsgang.The invention is described in more detail below with the aid of an example: An aqueous plastic dispersion e.g. Mowilith (Hoechst) is e.g. diluted 1:20 with water and 1.5 g boaxax per liter of undiluted dispersion as a flame retardant and optionally 1 g Mergal AF as a disinfectant. The aqueous dispersion is sprayed on in a weight ratio of 1: 1 with rock or hut wool onto a wide variety of surfaces. Tests were carried out on iron surfaces, galvanized iron surfaces, aluminum surfaces, eternit, wood, brick masonry and concrete with a thickness of up to 20 cm in one operation.
Es wurden ausgezeichnete Haftung, gute mechanische und thermische (λ = 0,03 kcal/mh°C) Eigenschaften der Überzüge sowie gute Oberflächenbeschaffenheit mit einem hohen Schall¬ schluckvermögen erzielt.Excellent adhesion, good mechanical and thermal (λ = 0.03 kcal / mh ° C.) properties of the coatings and good surface properties with a high sound absorption capacity were achieved.
OMPI Günstig werden etwa 2 bis etwa 25 Gew.-% Bindemittel, be¬ zogen auf das Gesamtgewicht der Beschichtuήg, eingesetzt. Insbesondere sind Prozentsätze zwischen 5 und 10 Gew.-% vor¬ teilhaft. Die erfindungsgemäß erhaltenen Beschichtungen eignen sich auch insbesondere als feuchtigkeitsregulierende Putze.OMPI About 2 to about 25% by weight of binder, based on the total weight of the coating, is advantageously used. Percentages between 5 and 10% by weight are particularly advantageous. The coatings obtained according to the invention are also particularly suitable as moisture-regulating plasters.
