Description

Verfahren zur Herstellung von Fußbodenbelagstoffen aus Mischpolymerisaten Es Nvurde gefunden, (laß man Fußbodenbelagstoffe in (1,ur Weise herstellen kann, (laß man mit geeigneten U'eichmachungsmitteln weichgemachte Mischpolymerisate aus Styrol und Butadien verwendet, die mindestens 5o')/o Styrol enthalten. Derartige Mischpolynivrisate werden \vorteilhaft durch 1-,'mulsiolispolynierisation erhalten, doch kann man auch in anderer Weise. z. B. mit 1 lilfe von Alkalimetallen hergestellte Mischpolynierisate verNvenden. Als Weichinaclitin-stnittel für die Nlischpolynierisate kommen die niedrigpolyineren flüssigen Styrole in 11)etraclit, doch k(")iiiieti auch von F, all zu Fall z. 13. Mitlialsäurcester, Thiodibuttersäureester usw. für . cli all in ()der in Miscliung \-erwendet werden. Bei si der Herstellung von Fußbodenbelagstoffen gemäß der Erfindung kann man im Bedarfsfalle auch mit .Mischungen arbeiten, die außer dem vorwiegend Styrol enthaltenden -Mischpolymerisat und dem Weichmachungsmittel noch festes Polystyrol enthalten, wobei der Zusatz an Weichmachungsmittel entsprechend zu beniessen ist.A method It found for the production of floor covering materials from copolymers Nvurde, (let it flooring materials in (1, for example, can be prepared, (let it plasticized with suitable U'eichmachungsmitteln copolymers of styrene and butadiene used, which contain at least 5o ') / o styrene. such Mischpolynivrisate be \ advantageously 1 -, 'mulsiolispolynierisation obtained, but one can also in other ways, for example with 1 lilfe of alkali metals produced Mischpolynierisate verNvenden As Weichinaclitin-stnittel for Nlischpolynierisate the niedrigpolyineren liquid styrenes etraclit in 11)... , but k (") iiiieti also from F, in all cases z. 13. Mitlialic acid esters, thiodibutyric acid esters etc. for . cli all in () the in miscliung \ -used If necessary, also work with mixtures which, in addition to the predominantly styrene-containing copolymer and the plasticizing agent tel still contain solid polystyrene, with the addition of plasticizers to be used accordingly.

Mit besonderem Vorteil wendet man die erwähnten Mischpolymerisate in Form ihrer wäßrigen, durch Enitilsionspolymerisation erhaltenen Dispersionen an, in denen man die Weichmachungsmittel, zweckmäßig in Form ihrer wäßrigen Fmulsion, dispergiert, worauf man die zur Herstellung von Fußbodenbelagstoffen gebräuchlichen Füllstoffe, wie Holz-, Korkmehl, Kreide, einmischt. Dies kann z. B. in einem heizbaren Kneter geschehen, dessen Temperatur so gewählt wird, daß das eingebrachte Wasser verdampft, wobei eine in der Wärme plastische Masse entsteht, die in Pressen oder auf einem Ziehkalander auf Platten oder Folien der gewünschten Stärke verarbeitet wird. Das Verhältnis zwischen M ischpolymerisat und Weichmachungsmittel richtet sich nach dem gewünschten Ergebnis und dem K-Wert des Mischpolymerisates bzw. dem Verhältnis von Styrol zu Butadien im Mischpolymerisat und ist durch einen Vorversuch leicht zu ermitteln. Bei spiel i In einem heizbaren Kneter werden 8o Teile eines Gemisches aus Holz- und Korkmehl, das außerdem gernahlene Kreide und Eisenoxydrot enthält, mit einer #väßrigen Dispersion, enthaltend 17 Teile eines durch Emulsionspolymerisation hergestellten Mischpolymerisates aus etwa 7o Teilen Styrol und 3o Teilen Butadien, sowie mit 3 Teilen eines vornehmlich Tristyrol enthaltenden flüssigen Polystyrols, gegebenenfalls in einulgierter Form, gemischt. Nach beendeter Mischung wird die erhaltene Masse durch Aufheizen des Kneters entwässert, worauf sie im abgekühlten Zustand in einer Strangpresse zerkleinert wird. Nach dem Wiederanwärmen wird die Masse sodann auf dem Kalander bei QO' zu einer Bahn ausgezogen.It is particularly advantageous to use the above-mentioned copolymers in the form of their aqueous dispersions obtained by polymerization polymerization, in which the plasticizers are dispersed, expediently in the form of their aqueous emulsion, after which the fillers commonly used for the production of floor coverings, such as wood and cork flour, Chalk mixed in. This can e.g. B. happen in a heatable kneader, the temperature of which is chosen so that the introduced water evaporates, creating a plastic mass in the heat, which is processed in presses or on a drawing calender on plates or foils of the desired strength. The relationship between M ischpolymerisat and softening depends on the desired result and the K value of the interpolymer or the ratio of styrene to butadiene in the copolymer and can easily be determined by a preliminary test. Example i In a heatable kneader, 80 parts of a mixture of wood and cork flour, which also contains ground chalk and red iron oxide, are mixed with an aqueous dispersion containing 17 parts of a copolymer made from about 70 parts of styrene and 3o parts of butadiene, as well as with 3 parts of a mainly tristyrene-containing liquid polystyrene, optionally in emulsified form. When the mixing is complete, the mass obtained is dehydrated by heating the kneader, whereupon it is comminuted in an extruder while it has cooled down. After reheating, the mass is then drawn into a web on the calender at QO '.

Beispiel 2 In analoger Weise w,ie im Beispiel i verfährt man bei der Herstellung einer Masse, die auf 8o Teile Füllstoffe io Teile eines Mischpolymerisates aus 7o Teilen Styrol und 3o Teilen Butadien, in Form der durch Emulsionspolymerisation und Konzentrieren erhaltenen 45 O/oigen wäßrigen Dispersion, 4 Teile Polystyrol, ebenfalls in Form einer möglichst konzentr,ieirten, durch Emulsionspolymerisation hergestellten wäßrigen Dispersion, und 6 Teile flüssiges polymeres Styrol, gegebenenfalls in emulgierter Form, enthält.EXAMPLE 2 In an analogous manner to Example 1, the procedure for the preparation of a mass containing 80 parts of a copolymer of 70 parts of styrene and 30 parts of butadiene in the form of the 45% aqueous solution obtained by emulsion polymerization and concentration is followed by 80 parts of filler Dispersion, 4 parts of polystyrene, likewise in the form of an aqueous dispersion prepared by emulsion polymerization, which is as concentrated as possible, and 6 parts of liquid polymeric styrene, optionally in emulsified form.
