Description
Spanabhebend bearbeitbarer und thermoplastisch verformbarer Werkstoff und Verfahren zu dessen Herstellung Es ist. bereits bekannt, dass man die Eigen schaften von Baumaterialien aus hydraulisch abbindenden Zementen, wie z. B.
Beton- oder Portland-Zement-Mörtel, durch begrenzte Zu sätze von weichmaeherfreien Pol.yvinylaeet.at- Emulsionen, deren optimale Menge bei 201/o liegt, wesentlich verbessern kann, wobei iaan Baumaterialien erhält, die eine wesentlich verbesserte Zug- und Druckfestigkeit sowie erhöhte Abriebfestigkeit aufzuweisen haben.
Solche Beton- resp. Poilland-Zement=Nlör- iel/I'olyvinylaeetat-:llisehungen binden ohne (las sonst übliche Wässern ab, das heisst also, (las vorhandene Emulsionswasser ist ausrei chend zum Abbinden solcher Mischungen.
Solche Beton- resp. Portla.nd-Zement-Mör- te] mit Zusätzen von maximal. 200/9 Poly vi- ny1aeetat werden ausschliesslich als Baumate rialien verwendet, sie sind nicht. thermo plastisch verforinba.r und unter normalen Ar- beitsbedingiin,,eri auch nicht spanabhebend bearheitbar.
Es ist weiterhin bekannt, da.ss man Bau materialien, wie z. B. Bachsteine, Dachziegel, Tafeln, nahtlose Rohre usw. herstellen kann, wenn man hydraulisch abbindende Zemente mit hangfaserigem Asbest (oder an Stelle von Asbest; Holzmehl) vermischt und zu, den entsprechenden Baumaterialien ( = Asbest- Zement resp. Holz-Beton ) v erpresst. Sol- ehe Baumaterialien sind unter Umständen zwar säg- und nagelbar, nicht. aber thermo plastisch verformbar.
Es wurde nun gefunden, dass man durch Vermischen von Polyvinylaeetat-Emtilsionen in grösseren Mengen als bisher mit Mischun- gen geeigneter Mengen aus hydraulisch ab bindenden Zementen und organischen oder anorganischen Faserstoffen, gegebenenfalls in Anwesenheit von Färbemitteln, wie z. B.
Farbstoffen und/oder Pigmenten eine pastöse Masse erhält, die durch Verformen -Lind Trocknen ein neuartiges Werkstoff-Material ergibt, welches nicht nur sehr gifte mechani sche Eigenschaften besitzt, sondern sich sehr gut spanabhebend bearbeiten und theriao- plastisch verformen lä.sst. Dieser Werkstoff ist gemäss der vorliegenden Erfindung da durch gekennzeichnet, da.ss er auf eine 100 Gewichtsteilen nicht. abgebundenem. Zement entsprechende Menge an abgebundenem Ze ment, wie z.
B. Portland-Zement., 40-80, vor zugsweise ö0-60 Gewichtsteile Polyvinyl- acetat (als feste Substanz gerechnet) und 5 bis 35 Gewichtsteile Faserstoff enthält. Das Verfahren zur Herstellung dieses Werkstoffes ist erfindungsgemäss dadurch gekennzeichnet, dass 100 Gewichtsteile hydratLlisch a,bbindbarer Zement, 40--80 Gewichtsteile Polyvinylaretat in Form einer wässrigen .Emulsion (vorzugs weise in Form einer 40-60 gewichtsprozenti gen,
zweckmässig weiehmacherfreien wässri- gen Emulsion) und 5-35 Gewichtsteile orga nische oder anorganische Faserstoffe, wie z. B. Holzmehl oder Asbest, zusammengemischt werden und die gebildete pastöse Masse dann verformt und getrocknet. wird.
Das auf diese Weise erhaltene neuartige Werkstoff-Material ist. in hohem Masse M derstandsfä.hig gegen Schlag-, Stoss-, Zu- und Druckbeanspritehung und lässt sich trotz dem in jeder Weise spanabhebend bearbeiten, das heisst also sägen, fräsen, hobeln, feilen so wie bohren, ferner nageln. Darüber hinaus kann man :das neuartige Werkstoffmaterial in jeder Weise oberflächlich behandeln, z. B. durch Polieren, Lackieren oder ähnliche all gemein bekannte Methoden, wodurch man neue Oberflächeneffekte .erhält.
Des weiteren weist. dieses neuartige Werkstoffmaterial gifte thermoplastische Eigenschaften auf, die es ermöglichen, unter bestimmten Arbeits- bedingungen, wie z. B. Druck und Wärme, das Material nochmals zu verformen, wie z. B. Rundungen, Profile und dergleichen anzubringen.
Nach dem vorstehend aufgeführten Ver fahren lassen sich beispielsweise Formgegen stände, wie Tür- und Wa.ndv erkleidungspla t- ten, so z. B. spezifisch leichte und schwer zerbrechliche Kacheln, Bodenbelag-Platten (Parkettplatten), Sitzausrüstungen, Toilet tensitze, Radiogehäuse, Bergmannshelme usw. herstellen, entweder durch Formen und Trocknen der frischen. (nassen) pastösen Werkstoffmasse oder durch spanabhebende Bearbeitung oder Verfor mung des vorgeformten, getrockneten Mate rials.

Portland-Zement und Holzmehl werden innig trocken gemischt, die Polyvinylaceta,c- Emulsion vorgelegt und das Portland-Zement- Holzmehl-Gemisch langsam zugesetzt.
Es bil det sich eine pastöse Masse, die dann mit oder ohne Druck verformt und unter Wärme einwirkung getrocknet wird. Die endgültige Härte der daraus hergestellten Formgegen stände stellt sich nach einiger Zeit. ein.
Machinable and thermoplastically deformable material and process for its production It is. already known that the properties of building materials from hydraulically setting cements, such as. B.
Concrete or Portland cement mortar, through limited additions of softener-free Pol.yvinylaeet.at emulsions, the optimal amount of which is 201 / o, can be significantly improved, with general building materials that have significantly improved tensile and compressive strength as well have increased abrasion resistance.
Such concrete respectively. Poilland cement = Nlöriel / I'olyvinylaeetat-: llisehungen bind without (read off otherwise usual water, that is, (the existing emulsion water is sufficient to set such mixtures.
Such concrete respectively. Portla.nd cement mortar] with additions of a maximum. 200/9 polyvinyl acetate are used exclusively as building materials, they are not. Thermo-plastically deformable and, under normal working conditions, also not machinable.
It is also known that building materials such. B. stream stones, roof tiles, panels, seamless pipes, etc. can be produced if you mix hydraulically setting cements with slag-fibrous asbestos (or instead of asbestos; wood flour) and add to the corresponding building materials (= asbestos-cement or wood-concrete) blackmailed. Such building materials may be sawn and nailed, but not. but thermo-plastically deformable.
It has now been found that by mixing Polyvinylaeetat-Emtilsionen in larger amounts than before with mixtures of suitable amounts of hydraulically from binding cements and organic or inorganic fibers, optionally in the presence of colorants such. B.
Dyes and / or pigments are given a paste-like mass which, through deforming and drying, results in a new type of material which not only has very toxic mechanical properties, but can also be machined very well and thermo-plastically deformed. According to the present invention, this material is characterized in that it is not per 100 parts by weight. tied. Cement corresponding amount of set Ze ment, such as.
B. Portland cement., 40-80, preferably before ö0-60 parts by weight of polyvinyl acetate (calculated as a solid substance) and contains 5 to 35 parts by weight of fiber. According to the invention, the process for producing this material is characterized in that 100 parts by weight of hydratable, bondable cement, 40-80 parts by weight of polyvinyl acetate in the form of an aqueous emulsion (preferably in the form of a 40-60 percent by weight,
expediently plasticizer-free aqueous emulsion) and 5-35 parts by weight of organic or inorganic fibers, such as. B. wood flour or asbestos, are mixed together and the pasty mass formed is then shaped and dried. becomes.
The new material material obtained in this way is. Able to withstand impact, impact, pressure and pressure, and can be machined in any way, i.e. sawing, milling, planing, filing as well as drilling and nailing. In addition, you can: treat the new material material superficially in any way, e.g. B. by polishing, painting or similar well-known methods, which gives you new surface effects.
Furthermore has. This new material poisons thermoplastic properties that make it possible to work under certain working conditions, such as B. pressure and heat to deform the material again, such. B. to attach curves, profiles and the like.
According to the above-mentioned process, for example, molded objects such as door and wall panels can be used, for example. B. specifically light and difficult to break tiles, flooring panels (parquet panels), seating equipment, toilet tensitze, radio housings, miner's helmets, etc. produce, either by molding and drying the fresh.

Portland cement and wood flour are mixed intimately dry, the polyvinylaceta, c-emulsion is submitted and the Portland cement-wood flour mixture is slowly added.
A pasty mass is formed, which is then shaped with or without pressure and dried under the influence of heat. The final hardness of the molded objects made from it arises after some time. one.
