Verfahren zur Beschleunigung der Vulkanisation von Xalltschukarten.
EMI1.1
EMI1.2
EMI1.3
Beschleuniger darstellen, die auch bei geringem Schwefelgehalt 20#25% höhere Zerreissfestigkeiten der Vulkanisate ergeben. Die als neue Vulkanisatoren erkannten Produkte der vorgenannten Klasse zeigen, dass ausserordentlich starke Beschleuniger vorliegen, die vielfach besser sind als z. B. Diarylguanidine. Die bessere Wirksamkeit der Vulkanisationsbeschleuniger gemäss vorliegender Erfindung ergibt sich aus den folgenden Versuchen :

Process to accelerate the vulcanization of Xallchu cards.
EMI1.1
EMI1.2
EMI1.3
Represent accelerators which, even with a low sulfur content, give the vulcanizates 20-25% higher tensile strengths. The products of the aforementioned class recognized as new vulcanizers show that there are extremely strong accelerators that are many times better than z. B. Diarylguanidines. The better effectiveness of the vulcanization accelerators according to the present invention results from the following tests:
1st attempt :
EMI1.4
<tb>
<tb> The <SEP> mixture <SEP> consists of <SEP>
<tb> 100-0 <SEP> parts <SEP> rubber.
<tb>
3-5. <SEP> sulfur,
<tb> 5 # 0 <SEP> ,, <SEP> zinc white,
<tb> 1'0,., <SEP> accelerator.
<tb>
Accelerator <SEP> 25 ', <SEP> 35', <SEP> 45 '<SEP> at <SEP> 3 <SEP> 1/2 <SEP> Atü.
<tb> Tolylaminoimidazoline <SEP> 204, <SEP> 182, <SEP> 179 <SEP> kg / cm2 <SEP> strength
<tb> Diphenylguanidine <SEP> 170,180, <SEP> 183 <SEP> ,, <SEP> ,,
<tb>
EMI1.5
Second attempt :
EMI1.6
<tb>
<tb> The <SEP> mixture <SEP> consists of <SEP>
<tb> 100-0 <SEP> parts <SEP> rubber.
<tb>
25 # 0 <SEP> ,, <SEP> soot,
<tb> 5 # 0 <SEP> ,, <SEP> zinc white.
<tb>
3-0 <SEP> sulfur,
<tb> 1'0 <SEP> "<SEP> accelerator.
<tb>
Accelerator <SEP> 10 ', <SEP> 301, <SEP> 601, <SEP> 90' <SEP> at <SEP> 2 # <SEP> Atü.
<tb> Tolylaminoimidazoline <SEP> 108, <SEP> 187, <SEP> 225, <SEP> 204kg / cm3 <SEP> strength,
<tb> Diphenylguanidm <SEP> 50, <SEP> 125, <SEP> 156, <SEP> 168 <SEP> "'"
<tb> Di-o-tolylguanidine <SEP> 34, <SEP> 100,150, <SEP> 174 <SEP>, <SEP>,
<tb>
The absolute strength values achieved are therefore significantly higher than those of the comparison products which are generally used.
