    "   Procédé de fixation de plaques en matières artificielles à base de chlorure polyvinylique sur des supports, par exemple en   cuir"   
Lorsqu'on colle des semelles de cuir sur des chaussures, on travaille ordinairement avec des colles à la nitrocellulose, sans que des difficultés se produisent, car si l'on rend rugueux ou gratte la semelle de cuir et le fond ou dessous de chaussure un bon collage est assuré sans que la fixation soit telle que la chaussure soit endommagée quand ori détache de nouveau la semelle. 



   Les semelles en matière synthétique à base de chlorure polyvinylique ne peuvent pas être fixées d'une manière satisfai- sante par ce procédé. On doit soit opérer des grattages spéciaux pour pouvoir travailler.avec des colles à la nitrocellulose, et même alors on n'obtient d'ailleurs pas des résultats tout à fait impeccables, ou bien on obtient une liaison trop solide si le col- 

 <Desc/Clms Page number 2> 

 lage n'est pas effectué avec des colles à la nitrocellulose mais avec une solution de chlorure polyvinylique. 



   Or, on a constaté, selon l'invention, qu'une fixation de plaques en matières artificielles à base de chlorure polyvinyli- que sur des supports en cuir ou en matière analogue, par exemple de semelles en ces matières premières sur le fond des chaussures, est possible d'une manière simple et satisfaisante même sans ren- dre la semelle rugueuse, si la surface à réunir de la plaque en matière artificielle est munie d'une couche d'un produit de poly- mérisation ou polymérisat mixte consistant en chlorure vinylique et en produits polymérisables tels que l'acétate vinylique les éthers vinyliques, les esters de l'acide acrylique etc. (les pro- duits à base de polystyrol sont moins appropriés). 



   On applique des produits qui ont été formés par polymérisa- tion des matières monomères. Les solutions de mélanges de diffé- rents polymérisats conviennent moins bien. Ces matières sont appliquées en badigeonnant la surface d'une solution des polymé- risats dans des solvants organiques. 



   Il n'est nullement nécessaire que la couche appliquée soit épaisse, Même une mince couche de polymérisat produit une réunion sûre de la plaque de matière artificielle avec le support, par exemple en cuir. La fraction ou portion de chlorure polyvinylique de la couche intermédiaire opère une liaison avec la plaque en matière artificielle, cependant que l'autre partie se lie bien avec la colle à la nitrocellulose, dont le fond de la chaussure et la plaque de matière artificielle peuvent être enduits. 



   L'invention offre l'avantage essentiel qu'il n'est pas néces- saire de gratter ou rendre rugueux d'une autre manière la matière artificielle polyvinylique, de sorte qu'elle est ménagée par rap- port à ce qui se passe dans le procédé appliqué jusqu'ici, dans lequel il se produisait une diminution de la durabilité de la plaque en matière artificielle à base de chlorure polyvinylique. 



   Selon l'invention, on procède de préférence en fournissant les plaques en matière artificielle enduites de la couche de 

 <Desc/Clms Page number 3> 

 polymérisat mixte, de sorte que le façonnier n'a plus qu'à en- duire de colle à la nitrocellulose le support et la matière ar- tificielle pour obtenir ensuite une réunion solide par simple pres sage ou compression. La liaison n'est pas d'une solidité telle qu'il ne soit pas possible de détacher, par exemple,une semelle devenue défectueuse, sans endommager la chaussure. On peut opérer de la même manière un collage de plaques ou bandes de chlorure polyvinylique sur du cuir ou des tissus pour des courroies de transmission ou dans d'autres buts. 



   Il a été proposé d'établir des revêtements protecteurs ou décoratifs moyennant emploi de produits de polymérisation mixtes, par exemple de chlorure vinylique avec un ester vinylique d'un acide aliphatique inférieur. Le produit de polymérisation mixte dissous dans un solvant volatil est, suivant cette proposition,, employé comme enduit. Cette propcsition ne s'occupe pas du prob- lème qui est à la base de l'invention. On ne peut point déduire de ce passage de littérature.que ces produits de polymérisation mixtes soient de bonnes colles, car la. propriété, qui y est men- tionnée, de l'adhérence solide au support peut se distinguer com- plètement de la propriété d'être une bonne colle. 



   Or, dans le cas de la fixation de plaques en matières arti- ficielles polyvinyliques, par exemple de semelles sur des supports, par exemple en cuir, il ne s'agit pas seulement de trouver une colle quelconque qui puisse produire une adhérence solide lorsque la plaque à coller est rendue rugueuse, mais il s'agit de préparer par exemple une semelle en matières artificielles à base de chlo- rure polyvinylique, de façon telle qu'elle puisse être fixée sur le fond de   chaussure   au moyen de la colle usuelle la nitrocel- lulose, cette liaison possédant, d'une part, une solidité d'adhé- d'autre part, rence suffisante, mais non telle, xxxxxxxxxxx qu'il ne soit pas pos- sible de détacher par exemple une semelle devenue défectueuse, sans détérioration du cuir, le travail devant utilement être effectué sans le grattage, qui affaiblit la plaque.

   Ce problème est résolu selon l'invention, et la solution de ce problème ne pouvait être déduite ni de cette proposition, ni   @@   d'une autre proposition connue préconisant d'appliquer des couches de gélatine sur des feuilles de polymères de chlorure vinylique de façon que ces couches y adhèrent solidement, des dérivés de la cel lulose pouvant être ajoutés au polymérisat mixte ou être employés comme couche particulière en vue de la fabrication de pellicules destinées à l'industrie photographique. Dans le cas de cette proposition, il s'agit d'un problème spécial, car il n'était pas possible jusque là de faire adhérer solidement une couche de gé- latine sur une feuille de chlorure polyvinylique, c'est-à-dire de nouveau d'un problème qui n'est pas celui de l'invention. 



   En effet, la réunion par collage par exemple d'une semelle en matières artificielles à base de chlorure polyvinylique avec le fond de chaussure au moyen de colles au chlorure polyvinylique était possible sans difficulté après que la semelle avait été rendue rugueuse, mais il se présentait toutefois l'inconvénient que cette liaison avait une force d'adhérence trop grande, telle qu'il n'était pas possible de détacher la semelle sans endommager le fon de la chaussure.

    "Method of fixing plates of artificial materials based on polyvinyl chloride on supports, for example of leather"
When gluing leather soles to shoes, one usually works with nitrocellulose glues, without any difficulty occurring, because if one roughens or scratches the leather sole and the bottom or underside of the shoe a good bonding is ensured without the binding being such that the shoe is damaged when ori detaches the sole again.



   Polyvinyl chloride synthetic soles cannot be satisfactorily fixed by this method. One must either operate special scrapings in order to be able to work with nitrocellulose glues, and even then one does not obtain completely impeccable results, or one obtains too strong a bond if the glue

 <Desc / Clms Page number 2>

 The treatment is not carried out with nitrocellulose adhesives but with a solution of polyvinyl chloride.



   However, it has been observed, according to the invention, that an attachment of plates made of artificial materials based on polyvinyl chloride on supports made of leather or similar material, for example soles made of these raw materials on the bottom of shoes , is possible in a simple and satisfactory manner even without making the sole rough, if the surface to be joined of the artificial material plate is provided with a layer of a polymerization product or mixed polymerizate consisting of chloride vinyl and polymerizable products such as vinyl acetate, vinyl ethers, acrylic acid esters etc. (products based on polystyrol are less suitable).



   Products are applied which have been formed by polymerization of the monomeric materials. Solutions of mixtures of different polymerizates are less suitable. These materials are applied by brushing the surface with a solution of the polymerizates in organic solvents.



   It is not necessary that the applied layer be thick. Even a thin layer of polymerizate produces a secure meeting of the plate of artificial material with the support, for example of leather. The polyvinyl chloride fraction or portion of the middle layer bonds with the artificial material plate, while the other part bonds well with the nitrocellulose glue, which the bottom of the shoe and the artificial material plate can be coated.



   The invention offers the essential advantage that it is not necessary to scrape or otherwise roughen the polyvinyl artificial material, so that it is spared with respect to what occurs in the invention. the process applied heretofore, in which there was a decrease in the durability of the plate made of artificial material based on polyvinyl chloride.



   According to the invention, the procedure is preferably by providing the plates of artificial material coated with the layer of

 <Desc / Clms Page number 3>

 mixed polymerizate, so that the fabricator only has to apply nitrocellulose glue to the support and the artificial material in order then to obtain a solid union by simple pressing or compression. The connection is not so strong that it is not possible to detach, for example, a sole that has become defective, without damaging the shoe. The bonding of plates or strips of polyvinyl chloride to leather or fabrics for transmission belts or for other purposes can be carried out in the same way.



   It has been proposed to establish protective or decorative coatings by using mixed polymerization products, for example vinyl chloride with a vinyl ester of a lower aliphatic acid. The mixed polymerization product dissolved in a volatile solvent is, according to this proposal, employed as a coating. This proposal does not deal with the problem which is the basis of the invention. It cannot be deduced from this passage in the literature that these mixed polymerization products are good adhesives, because the. property, which is mentioned therein, of solid adhesion to the substrate can be completely distinguished from the property of being a good glue.



   However, in the case of the fixing of plates of polyvinyl artificial materials, for example soles on supports, for example of leather, it is not only a question of finding any glue which can produce a solid adhesion when the The plate to be glued is roughened, but this involves preparing, for example, a sole of artificial materials based on polyvinyl chloride, so that it can be fixed to the bottom of the shoe by means of the usual glue. nitrocellulose, this bond having, on the one hand, a strength of adhesion, on the other hand, sufficient strength, but not such, xxxxxxxxxxx that it is not possible to detach, for example, a sole that has become defective, without deterioration of the leather, the work usefully having to be done without the scraping, which weakens the plate.

   This problem is solved according to the invention, and the solution of this problem could not be deduced either from this proposal, nor from another known proposal recommending the application of layers of gelatin on sheets of vinyl chloride polymers of so that these layers adhere firmly thereto, cellulose derivatives can be added to the mixed polymerizate or be used as a special layer for the manufacture of films intended for the photographic industry. In the case of this proposal, this is a special problem, as it was not possible until then to firmly adhere a layer of gelatin to a sheet of polyvinyl chloride, i.e. again a problem which is not that of the invention.



   In fact, joining by gluing, for example, a sole made of artificial materials based on polyvinyl chloride with the bottom of the shoe by means of polyvinyl chloride glues was possible without difficulty after the sole had been roughened, but it appeared however the drawback that this link had too great an adhesive force, such that it was not possible to detach the sole without damaging the bottom of the shoe.
