" Plastifiants pour mélanges de caoutchouc ".
Il est connu de faciliter le travail de mélanges de oa- outchoues synthétiques au moyen de ltaddition de produits dits plastifiants. Les matières généralement utilisées à cet effet ont toutefois l'inconvénient dtexiger d'être ajoutées aux mé- langes dans des proportions relativement fortes allant jusqu'à 20 parties et davantage pour 100 parties de caoutchouc. Des additions de plastifiant de cet ordre réagissent toutefois dans un sens défavorable sur les propriétés méoaniques du mé- lange, en particulier sa résistanoe au déchirement, sa résis-
<Desc/Clms Page number 2>
sa tance à l'usure, sa dureté et/ténacité.
Or, il a été proposé suivant le brevet belge N 445 038 déposé le 1 avril 1942 d'utiliser comme plastifiants pour des mélanges de caoutchouc des monoamines primaires, secondaires ou tertiaires, ou des diamines primaires avec de longues chaî- nes aliphatiques d'atomes de carbone, ou bien leurs sels, car ces matières, même en faible proportion, déterminent une action plastifiante remarquable,
On a trouvé ensuite que les amides aromatiques hydratés substitués, produits de substitution d'acides gras comportant sept atomes de carbone ou davantage, influencent dans un sens extrêmement favorable, même en petite proportion, la facilité de travail de mélanges de caoutchouc synthétique.
Même par l'ad- dition d'environ 5 parties de oes matières rapportées à 100 par- ties de oaoutohouo synthétique on' obtient une matière qu'il est possible, éventuellement après addition d'autres plastifiants, de travailler d'une façon très lisse à la calandre ou à la bou- dineuse.
Comme exemple d'un plastifiant suivant l'invention on mentionnera le oyolohexylamide d'acides gras à 7 à 9 atomes de carbone. L'invention n'est toutefois pas limitée à ces exemples.
Les matières mentionnées peuvent être utilisées non seule- ment pour les mélanges de caoutchouc synthétique, mais aussi pour les mélanges de caoutohouo naturel.

"Plasticizers for rubber compounds".
It is known to facilitate the work of mixtures of synthetic oats by means of the addition of so-called plasticizers. The materials generally used for this purpose, however, have the disadvantage of requiring to be added to the mixtures in relatively high proportions of up to 20 parts and more per 100 parts of rubber. Plasticizer additions of this order, however, have an adverse effect on the mechanical properties of the mixture, in particular its tear resistance, its strength.
<Desc / Clms Page number 2>
its resistance to wear, hardness and toughness.
However, it has been proposed according to Belgian patent N 445 038 filed on April 1, 1942 to use as plasticizers for rubber mixtures primary, secondary or tertiary monoamines, or primary diamines with long aliphatic chains of atoms. of carbon, or their salts, because these matters, even in small proportion, determine a remarkable plasticizing action,
Subsequently, it has been found that substituted aromatic hydrated amides, substitution products of fatty acids having seven or more carbon atoms, influence in an extremely favorable direction, even in a small proportion, the workability of synthetic rubber mixtures.
Even by adding about 5 parts of these materials based on 100 parts of synthetic ooutohouo a material is obtained which it is possible, possibly after addition of other plasticizers, to work in a very smooth with the calender or the chopper.
As an example of a plasticizer according to the invention, mention will be made of oyolohexylamide of fatty acids with 7 to 9 carbon atoms. The invention is not however limited to these examples.
The materials mentioned can be used not only for synthetic rubber mixtures, but also for natural rubber mixtures.
