Abstract

Method for the surface treatment of at least one part of a hollow body comprising a plastic, wherein the plastic comprises at least one antacid.

Description

       

   <Desc/Clms Page number 1> 
 



  Exemple 6
Un réservoir à carburant identique à celui selon l'exemple 5 a été réalisé de la même manière. 



   On a traité superficiellement ce réservoir de la même manière que selon l'exemple 4R, si ce n'est qu'une seconde étape de neutralisation du réservoir a été ajoutée durant laquelle il a été rempli avec 3 litres d'une solution aqueuse contenant 5 % en volume de polyéthylèneimine LUPASOL P de poids moléculaire compris entre 600 000 et 1 000 000, puis agité durant 3 minutes. 



   Après 3 mois, en état de régime, la perméabilité de ce réservoir, mesurée par perte de poids selon la norme ECE 34 (Annexe 5), était de 0,4 g. mm/m2. j 

 <Desc/Clms Page number 2> 

 REVENDICATIONS   1 - Procédé   pour le traitement superficiel d'au moins une partie d'un corps creux comprenant une matière plastique, caractérisé en ce que la matière plastique comprend au moins un antiacide. 



   2-Procédé selon la revendication 1, dans lequel le corps creux est un réservoir à carburant. 



   3-Procédé selon la revendication 1, dans lequel le corps creux est une tubulure d'alimentation en carburant. 



   4-Procédé selon l'une quelconque des revendications précédentes, dans lequel la matière plastique est un polyéthylène haute densité. 



   5-Procédé selon la revendication 4, dans lequel le polyéthylène haute densité a été obtenu par polymérisation en présence d'un catalyseur différent des catalyseurs Ziegler. 



   6-Procédé selon l'une quelconque des revendications précédentes, dans lequel l'antiacide est choisi parmi les savons métalliques comprenant de 8 à 32 atomes de carbone, le carbonate de calcium, les hydrotalcites, les dérivés époxydés et les sels dérivés des béta-dicétones. 



   7-Procédé selon la revendication 6, dans lequel l'antiacide est une hydrotalcite. 



   8-Procédé selon l'une quelconque des revendications précédentes, dans lequel le traitement superficiel comprend au moins une étape de sulfonation et au moins une étape de neutralisation.

  Example 6
A fuel tank identical to that according to Example 5 was produced in the same way.



   This tank was treated superficially in the same way as in Example 4R, except that a second stage of neutralization of the tank was added during which it was filled with 3 liters of an aqueous solution containing 5 % by volume of LUPASOL P polyethyleneimine of molecular weight between 600,000 and 1,000,000, then stirred for 3 minutes.



   After 3 months, in steady state, the permeability of this reservoir, measured by weight loss according to the ECE 34 standard (Annex 5), was 0.4 g. mm / m2. j

 CLAIMS 1 - Method for the surface treatment of at least part of a hollow body comprising a plastic material, characterized in that the plastic material comprises at least one antacid.



   2-A method according to claim 1, wherein the hollow body is a fuel tank.



   3-A method according to claim 1, wherein the hollow body is a fuel supply manifold.



   4-A method according to any one of the preceding claims, wherein the plastic is a high density polyethylene.



   5-A method according to claim 4, wherein the high density polyethylene was obtained by polymerization in the presence of a catalyst different from the Ziegler catalysts.



   6-Process according to any one of the preceding claims, in which the antacid is chosen from metallic soaps comprising from 8 to 32 carbon atoms, calcium carbonate, hydrotalcites, epoxidized derivatives and salts derived from beta- diketones.



   7-A method according to claim 6, wherein the antacid is a hydrotalcite.



   8-Process according to any one of the preceding claims, in which the surface treatment comprises at least one sulphonation step and at least one neutralization step.
