Description
Antriebsriemen und Förderbänder aus gereckten Polyamiden oder Polyurethanen Es sind bereits Antriebsriemen und Förderbänder aus gereckten Polyamiden oder Polyurethanen vorgeschlagen, die geringe Mengen einer aromatischen oder hydroaromatischen Oxyverbindung enthalten.Drive belts and conveyor belts made of stretched polyamides or polyurethanes It are already drive belts and conveyor belts made of stretched polyamides or polyurethanes suggested the small amounts of an aromatic or hydroaromatic oxy compound contain.
Diese Riemen und Bänder sind praktisch spleißfest.These straps and ribbons are practically splice resistant.
Es wurde nun gefunden, daß gereckte Riemen aus Polyamiden oder Polyurethanen ebenfalls praktisch spleißfest sind, wenn sie neben oder an Stelle der aromatischen oder hydroaromatischen Oxyverbindungen geringe Mengen, d. h. bis zu 5 01o aromatischer Sulfonamide enthalten. It has now been found that stretched belts made of polyamides or polyurethanes are also practically splice-resistant if they are used alongside or in place of the aromatic or hydroaromatic oxy compounds, small amounts, d. H. up to 5 01o more aromatic Contain sulfonamides.
Geeignete derartige Sulfonamide sind beispielsweise J,enzol-, Toluol-, Xylolsulfonamid und entsprechende alkylierte Sulfonamide, wie Benzolsulfomonomethyl amid, Benzolsulfodimethylamid, Benzolsulfomonoäthylamid, Toluolsulfomonoäthylamid, Benzolsulfomonooxäthylamid, Benzolsulfomonobutylamid. Suitable such sulfonamides are, for example, J, enzene, toluene, Xylene sulfonamide and corresponding alkylated sulfonamides such as benzenesulfomonomethyl amide, Benzolsulfodimethylamid, Benzolsulfomonoäthylamid, Toluenesulfomonoäthylamid, Benzenesulfomonooxethylamide, benzenesulfomonobutylamide.
Die Stoffe können für sich oder in Mischung untereinander oder auch mit aromatischen oder hydroaromatischen Oxyverbindungen, gegebenenfalls auch mit anderen Weichmachern, verwendet werden. The substances can be used alone or in a mixture with one another or also with aromatic or hydroaromatic oxy compounds, optionally also with other plasticizers, can be used.
Beispiel I 2000 Teile eines in Gegenwart von 50 Teilen Benzolsulfomonomethylamid hergestellten Polyamids aus e-Caprolactam werden nach Beendigung.der Kondensation zu einem Band von 45 mm Breite und 1,2 bis I,4 mm Dicke aus dem Kondensationsgefäß gedrückt. Example I 2000 parts of a benzenesulfomonomethylamide in the presence of 50 parts made of polyamides After the end of the Condensation to a tape 45 mm wide and 1.2 to 1.4 mm thick from the condensation vessel pressed.
Das Band wird anschließend gereckt. Nach langer Lagerung bei gewöhnlicher Temperatur und etwa 30 bis 40 Olo relativer Luftfeuchtigkeit zeigt das Band noch keine Neigung zum Spleißen. In der Längsrichtung angeschnitten, läßt es sich nur mit erheblicher Kraft weiterreißen.The tape is then stretched. After long storage at ordinary The tape still shows the temperature and about 30 to 40% relative humidity no tendency to splice. Cut in the longitudinal direction, it can only be done tear on with considerable force.
Ein gleiches Band aus einem in Abwesenheit von. A same tape from one in the absence of.
Benzolsulfomonomethylamid kondensierten Polyamid reißt unter den gleichen Bedingungen schon bei geringem Kraftaufwand unter Geräusch leicht weiter; Entsprechende Ergebnisse erhält man, wenn man statt 50 Teilen Benzolsulfomonomethylamid 50 Teile Benzolsulfomonomethylamid und 12 Teile ß, ß'-Di-(oxyphenyl)-dimethylmethan oder auch 50 Teile Benzolsulfomonomethylamid und 6 Teile Resorcin, oder statt Benzolsulfomonomethylamid ein Gemisch aus etwa 45 Teilen Benzolsulfomonoäthylamid, 17 Teilen Benzolsulfodiäthylamid, 35 Teilen Benzolsulfomonobutylamid und 3 Teilen Benzolsulfamid, oder ein Gemisch aus 75 Teilen Benzolsulfomonomethylamid und 25 Teilen Benzolsulfomonobutylamid, oder entsprechende Mengen anderer vorstehend genannter Sulfonamide verwendet.-Beispiel 2 Eine Lösung von 200 Teilen Caprolactam in 6oTeilen Wasser wird mit einer Lösung von 0,4 Teilen Cyclohexanontetrapropionsäure und 0,3 Teilen Hexamethylendiamin in IO Teilen Wasser und außerdem mit IO Teilen Benzolsulfomonomethylamid unter Rühren versetzt. Das Gemisch wird in üblicherWeise zum Polyamid kondensiert und das entstehende Kondensationsprodukt aus dem Reaktionsgefäß in Form eines Bandes, beispielsweise von 30 bis IOO mm Breite und °,S bis r,8 mm Stärke, gedrückt. Das Band wird anschließend gereckt. Daraus hergestellte Treibriemen zeigen praktisch keine Neigung zum Spleißen in der Längsrichtung.Benzenesulfomonomethylamide condensed polyamide tears under the same Conditions easily continue with little effort and noise; Appropriate Results are obtained if 50 parts are used instead of 50 parts of benzenesulfomonomethylamide Benzolsulfomonomethylamid and 12 parts ß, ß'-Di- (oxyphenyl) -dimethylmethane or also 50 parts of benzenesulfomonomethylamide and 6 parts of resorcinol, or instead of benzenesulfomonomethylamide a mixture of about 45 parts of benzenesulfomonoethylamide, 17 parts of benzenesulfodiethylamide, 35 parts of benzenesulfomonobutylamide and 3 parts of benzenesulfamide, or a mixture from 75 parts of benzenesulfomonomethylamide and 25 parts of benzenesulfomonobutylamide, or corresponding amounts of other sulfonamides mentioned above are used. Example 2 A solution of 200 parts of caprolactam in 60 parts of water is combined with a solution of 0.4 part of cyclohexanone tetrapropionic acid and 0.3 part of hexamethylenediamine in 10 parts of water and 10 parts of benzenesulfomonomethylamide with stirring offset. The mixture is condensed in the usual way to the polyamide and the resulting Condensation product from the reaction vessel in the form of a tape, for example from 30 to 100 mm wide and °, S to r, 8 mm thick. The tape will then stretched. Drive belts made therefrom show practically no tendency to splice in the longitudinal direction.
