  " Procédé dé préparation d'un adhésif et adhésif   obtenn   par ce procédé ". 



   La présente invention est relative à an procédé de préparation d'an adhésif comportant de la colophane desti- née principalement à être étendae sur des coarroies de façon à éviter le glissement de celles-ci. 



   Saivant l'invention, on ajoute de la colophane à de   l'huile   et on fait boaillir le mélange. On ajoate ensuite du caoutchouc et on continae à chauffer jasqa'à ce qae les morceaux de caoutchouc soient disparas. Pour faciliter la disparition des derniers morceaax de caoutchouc, on peat ajoater an pea d'acide chlorhydriqae, à la fin da chaaffage   oa   après celai-ci. 



   Pour réaliser ce procédé, on procède par exemple   comme sait : onprend an décilitre d'huile de colza, on y

   ajoate   50   gr.   de colophane et on chauffe le mélange   jasqa'à   éballition. Une quantité moindre de colophane aa- rait comme effet de diminaer le pouvoir adhésif da produit obtena finalement ; tandis   qa'ane   proportion supérieure aa- rait comme effet de rendre le   prodait   pratiqaement inem- ployable à caase de son trop grand poavoir adhésif. 



   A titre d'exemple, il est à noter qae si on   employe   environ 65 gr. de colophane, le produit obtena n'est plas d'an emploi pratiqae. 



   On   ajoate à   ce mélange environ 1100 gr. de caoutchouc et on continae à chaaffer   jasqa'aa   moment où les morceaux de caoutchouc sont disparue. rendant ce temps, on peut éventuellement ajoater 2 cm3 de créoline. Lorsqu'on estime qae les morceaax de caoutchouc sont disparue, on joue éventaellement 5 gr. d'aniline. On cesse de chaaffer et on 
3 ajoate 3 cm d'acide chlorhydrique également conna dans le commerce soas le nom d'acide mariatique. cette addition a comme effet de faciliter éventuellement la disparition des petits morceaux de caoutchouc restants. 



   On filtre ensuite le produit   obtena   et on le met en boites pendant   qa'il   est encote chaud. 



   On obtient ainsi environ 1 kg. d'adhésif qai peat se conserver indéfiniment et qai, lorsqu'il est étenda légè- rement sur une coarroie augmente considérablement l'adhé- rence de celle-ci par rapport aax poalies sur lesqaelles elle passe. 



   Il est évident qae l'invention n'est pas exclusivement limitée   aa   procédé   particalier   tel qa'il vient d'être décrit et qae des modifications   pourraient   être apportées dans la proportion des constituants intervenant dans la réalisation, sans sortir de la portée da présent brevet.

  "Method of preparing an adhesive and adhesive obtained by this method".



   The present invention relates to a process for the preparation of an adhesive comprising rosin intended mainly to be spread on coarroids so as to prevent slippage thereof.



   According to the invention, rosin is added to oil and the mixture is boiled. Rubber is then added and heating is continued until the pieces of rubber are gone. To facilitate the disappearance of the last pieces of rubber, one peat ajoater an pea of hydrochloric acid, at the end of the chaaffage oa after this.



   To carry out this process, one proceeds for example as known: one takes one deciliter of rapeseed oil, one takes

 <Desc / Clms Page number 2>

   ajoate 50 gr. rosin and heat the jasqa 'mixture to boiling. A less amount of rosin would have the effect of reducing the adhesive power of the product finally obtained; while a higher proportion would have the effect of rendering the product practically inoperable at the expense of its too large adhesive strength.



   By way of example, it should be noted qae if approximately 65 gr. of rosin, the product obtained is not used practically.



   About 1100 gr is added to this mixture. rubber and we continued to chaaffer jasqa'a when the pieces of rubber are gone. making this time, we can optionally add 2 cm3 of creoline. When we estimate that the rubber pieces have disappeared, we eventually play 5 gr. aniline. We stop chaffing and we
3 ajoate 3 cm of hydrochloric acid also known commercially soas the name of mariatic acid. this addition has the effect of possibly facilitating the disappearance of the remaining small pieces of rubber.



   The product obtained is then filtered and placed in cans while it is hot.



   This gives about 1 kg. of adhesive qai peat is retained indefinitely and qai, when it is spread lightly on a belt, considerably increases the adhesion of the latter relative to the poalies on which it passes.



   It is obvious that the invention is not exclusively limited to a particalier process as it has just been described and that modifications could be made in the proportion of the constituents involved in the production, without going beyond the scope of this patent. .
