Description

  

  Brevet additionnel subordonné au brevet     principal    NO 384115    Peinture applicable sous l'eau    La présente invention a pour objet une     peinture     applicable sous l'eau selon la     revendication    I -du  brevet principal,     caractérisée    par le fait     qu'elle    com  prend en outre au     moins    un solvant dont la     solubilité     dans l'eau est inférieure .à 0,1g par litre.  



  Il a été constaté que dans ladite peinture, le ou les  solvants solubles dans l'eau     .agissant    comme tiers sol  vants     entraînent    dans l'eau le ou     les    solvants insolu  bles jusqu'à leur     élimination    complète de la couche  de     peinture.     



  Ainsi un mélange de     .solvants    constitué par  43 parties de xylène (insoluble dans l'eau)  43 parties de chlorure de méthylène  43     parties    d'alcool     butylique,     s'élimine complètement de la couche de     peinture.    Le  film durcit :sous l'eau plus     lentement    que dans     le    cas  des     solvants        solubles    dans l'eau par exemple en     une     huitaine de jours.  



  Comme très peu soluble dans     .l'@cau,    on va aussi  employer le toluène .par exemple (solubilité 0,047 g  à 16- C).  



  La présence de solvants polaires     augmente        sen-          siblement    l'adhérence de la     couche    de peinture au  moment de l'application et renforce ainsi l'action de  l'amine.  



  Il est avantageux, dans certains cas, d'ajouter à la       peinture    de l'oxyde de zinc et un gel     bentonite        orga-          nophile.    L'oxyde de zinc allège légèrement la partie  pigmentaire de la peinture et retarde donc -la sédi  mentation du minimum,     ,tandis    que le gel de     bento-          nite        organophile,    de     préférence    du type     diméthylacta-          decyl:

  amoni.um7bentonite,    a la     propriété,        par        modiL          fication    de la     viscosité        (thixotropie)    de retarder voire  même de supprimer la     sédimentation    des     pigments     sans nuire à     l'adhérence    de la     peinture.    La     bentone          est        ajoutée        en        proportion        de        1,3    à     2,

  5        %        du        poids     total de la peinture.    L'emploi de solvants insolubles ou     très    peu solu  bles dans l'eau en mélange avec     -des        solvants    hydro  solubles a l'avantage de prolonger la durée de stabilité  du mélange solvant sous l'eau     et    de     faciliter    grande  ment l'application de la peinture subaquatique     réalisée     ainsi avec aisance de même que la     reprise    sur une  grande surface.

  Additional patent subordinate to main patent NO 384115 Paint applicable under water The present invention relates to a paint applicable under water according to claim I - of the main patent, characterized in that it also comprises at least one solvent whose solubility in water is less than 0.1 g per liter.



  It has been observed that in said paint, the water-soluble solvent (s) acting as a third solvent entrain the insoluble solvent (s) in the water until they are completely removed from the paint layer.



  Thus a mixture of .solvents consisting of 43 parts of xylene (insoluble in water) 43 parts of methylene chloride 43 parts of butyl alcohol is completely removed from the paint layer. The film hardens: under water more slowly than in the case of water-soluble solvents, for example in a week or so.



  As very slightly soluble in water, toluene will also be used, for example (solubility 0.047 g at 16 ° C.).



  The presence of polar solvents significantly increases the adhesion of the paint layer at the time of application and thus enhances the action of the amine.



  It is advantageous in some cases to add zinc oxide and an organic bentonite gel to the paint. Zinc oxide slightly lightens the pigmentary part of the paint and therefore delays sedimentation to a minimum, while organophilic bentonite gel, preferably of the dimethylactadecyl type:

  amoni.um7bentonite, has the property, by modifying the viscosity (thixotropy) of delaying or even eliminating the sedimentation of pigments without adversely affecting the adhesion of the paint. Bentone is added in a proportion of 1.3 to 2,

  5% of the total weight of the paint. The use of solvents which are insoluble or very slightly soluble in water mixed with water-soluble solvents has the advantage of prolonging the period of stability of the solvent mixture under water and of greatly facilitating the application of the solution. underwater painting thus carried out with ease as well as the recovery on a large surface.
