Procédé de fabrication 0* articles en caoutchouc et substances analogues.
La présente invention se rapporte à des perfection- nements apportés , 1-a fabrication d'articles en caoutchouc et elle a principalement pour objet un procédé simple et perfectionné pour obtenir des articles en caoutchouc ayant une surface de diverses couleurs, et une paroi d'épaisseur variée, bien que le procédé ne soit pas limité à la fabri4 cation d'articles de ce genre,,, Il a déjà été proposé de produire du caoutchouc brut en pulvérisant du latex pur ou mélangé à des additions appropriées, et en le soumettant à l'action d'un courant de gaz chauffé, de manière que les particules de latex précipitées qui s'agglomérât forment
<Desc/Clms Page number 2>
une masse sèche.-.
Suivant la présente invention, le latex ou une autre dispersion aqueuse du caoutchouc est pulvérisé sur une sur- face quelconque de telle sorte que 1-a substance pulvérisée, lorsqu' elle vient se placer sur un support, se trouve à l'é- tat humide*- Le latex peut, quand c' est nécessaire, être additionné d'une substance de conservation appropriée, par exemple l'ammoniaque, et être mélangé de diverses additions et agents de vulcanisations
Le latex, ou un mélange du.
genre précité de ce latex, au moyen d'un pistolet ou d'un autre outil injecteur peut être injecté, /sur un moule ayant la conformation de l'article à produire, on peut aussi .-appliquer le latex ou le mélange, sur une pièce déjà conformée au préalable, et consistant en un précipité de caoutchouc qui a été tiré, d'une manière quelconque connue, de solutions aqueuses .de caoutchouc, .dans le but d' augmenter l'épaisseur de la paroi aux endroits voulus, ou d'obtenir sur cette paroi un dessin quelconque à plat ou en relief
Le Procédé peut également être employé pour la fa- brication d'articles multicolores, ou pour effectuer le mélange de diverses couleur,* Dans ce but,
on ajoute à la dispersion de caoutchouc un colorant appropriée
Le nouveau procédé est particulièrement applicable concurremment avec tous les procédés qui permettent l'a fabri- cation d' articles en caoutchouc à l'état mouillé ou humide par exemple pour des articles qui sont produits à partir de dispersions aqueuses de caoutchouc*-
La densité de la dispersion de caoutchouc et les additions peuvent être choisies suivant le genre d' article à fabriquer, suivant le dessin, ou suivant la conformation par- ticulière de la surface à produiras
Après injection de la dispersion de caoutchouc,
on sèche le produit et on le vulcanise d'une manière quelconque connues
<Desc/Clms Page number 3>
Ci-après quelques exemples de mélanges à employer pour l'exécution du procédé., ler Exemple -*
73,75 parties en poids de caoutchouc, sous forme de latex naturel, conservé ou concentré;
10 parties en poids d'oxyde de zinc; 10 parties en poids de blanc de Meudon N2 1 2,5 parties en poids de souffe;
0,25 parties en poids de diéthyldithiocarbonate de diethyla- mine*-
Quand. on emploie du latex conservé ou concentré, les agents de conservation ou de stabilisation existants peuvent suffire;
sans cela, on ajoute au mélange ci-dessus par exem- pl e 0.5% de caséine et 2% d'ammoniaque -aqueux*
2ème Exemple:-
91.5 parties en poids de latex naturel, conservé ou concentré
5 parties en poids d'oxyde de zinc;
2,parties en poids de soufre; 0,5 parties en poids de carbothionolate de pipéridine;
1 partie en poids de vulcafor rouge.
En cas de besoin, on peut pour la stabilisation et la conservation, ajouter 1% de stéarate de sodium, 0/5% de caséine, et 1% d'ammoniaque aqueux.-
En outre des produits désignés plus haut, on peut également ajouter d'autres colorants minéraux ou organiques*.

Manufacturing process 0 * articles of rubber and the like.
The present invention relates to improvements in the manufacture of rubber articles, and it mainly relates to a simple and improved process for obtaining rubber articles having a surface of various colors, and a wall of rubber. varied thickness, although the process is not limited to the manufacture of articles of this kind ,,, It has already been proposed to produce raw rubber by spraying pure latex or mixed with suitable additions, and subjecting it by the action of a stream of heated gas, so that the precipitated particles of latex which agglomerate form
<Desc / Clms Page number 2>
a dry mass.
In accordance with the present invention, the latex or other aqueous dispersion of the rubber is sprayed onto any surface such that the sprayed substance, when placed on a support, is in the state. wet * - The latex can, when necessary, be added with a suitable preservative, for example ammonia, and be mixed with various additions and curing agents
Latex, or a mixture of.
the aforementioned type of this latex, by means of a gun or other injector tool can be injected, / on a mold having the conformation of the article to be produced, it is also possible.-apply the latex or the mixture, on a part already shaped beforehand, and consisting of a rubber precipitate which has been drawn, in any known manner, from aqueous solutions of rubber, in order to increase the thickness of the wall in the desired places, or to obtain on this wall any drawing flat or in relief
The method can also be employed for the manufacture of multi-colored articles, or for effecting the mixing of various colors, * For this purpose,
a suitable colorant is added to the rubber dispersion
The new process is particularly applicable in conjunction with all processes which allow the manufacture of rubber articles in the wet or wet state, for example for articles which are produced from aqueous rubber dispersions * -
The density of the rubber dispersion and the additions can be chosen according to the kind of article to be manufactured, according to the design, or according to the particular conformation of the surface to be produced.
After injection of the rubber dispersion,
the product is dried and vulcanized in any known manner
<Desc / Clms Page number 3>
Below are some examples of mixtures to be used for carrying out the process., Example - *
73.75 parts by weight of rubber, in the form of natural latex, preserved or concentrated;
10 parts by weight of zinc oxide; 10 parts by weight of Meudon white N2 1 2.5 parts by weight of breath;
0.25 parts by weight of diethylamine diethyldithiocarbonate * -
When. preserved or concentrated latex is used, existing preservatives or stabilizers may be sufficient;
otherwise, to the above mixture are added, for example, 0.5% casein and 2% aqueous ammonia *
2nd Example: -
91.5 parts by weight of natural latex, preserved or concentrated
5 parts by weight of zinc oxide;
2, parts by weight of sulfur; 0.5 parts by weight of piperidine carbothionolate;
1 part by weight of red vulcafor.
If needed, for stabilization and storage, add 1% sodium stearate, 0/5% casein, and 1% aqueous ammonia.
In addition to the products designated above, it is also possible to add other inorganic or organic dyes *.
