  Procédé de fabrication d'un élément décoratif en matière plastique
 La décoration par craquelure d'une surface d'un corps est connue depuis longtemps. On sait notamment que   certaines laques. appliquées comme revête-    ment ont la propriété de se craqueler, donnant ainsi à l'objet revêtu un effet esthétique particulier. De même, dans la technique du verre, on peut obtenir des   oraquèlements      en-surface ou    en profondeur et cet effet est appliqué depuis longtemps pour la fabrication de vases, ou, autres objets d'intÚrieur en verre.



   Jusqu'ici ron   n'a      cependant    pas utilisé cet effet pour les matières plastiquas.



   La présente invention a précisément pour objet un procédé de fabrication d'un élément décoratif en    matière plastique salon'lequel on coule de la matière    plastique dans un moule ayant la frome dudit ÚlÚment
 Ce procédé est caractérisé par'le fait que l'on choisit l'épaisseur des parois de cet élément de même que les caractéristiques physiques de ladite matière plastique de manière   qu'en se polymérisanjt une partie    au moins de la   masse. de matière'plastique    se craquelle.



   D'une   manière générale, il's'agit    de   créer    artificiel  lement      des tensions internes, de préférence sur    la face visible de la matière plastique, afin d'en provoquer le craquèlement par rapport à une couche de base qui doit être homogène pour jouer le rôle de support.



  A cet effet, il est possible de   polymériserd'abordla    couche de base et de faire'appel à une préforme ou à une armature.



   Les tensions sont fonction des caractéristiques physiques inhérentes à la fabrication des   éléments,    à savoir l'épaisseur de la matière plastique, la forme de la matière plastique et du   moule, les caractéristiques    de   polymérisation de la maftière    plastique et les agents thermiques   susceptibles    de l'influencer, prises   séparé-    ment ou en combinaison.



   L'épaisseur de la matière plastique moulée joue un rôle dans la mesure o¯ elle crÚe des conditions de   polymédsation    de la matière plastique   diifferenciées    localement, à savoir, par   exemjpte, ume polymérisation    plus rapide des couches supérieures de la matière que des couches iches infÚrieures, confÚrant aux premi¯res   structure    instable dont le rÚsultat est un craquèlement et aux secondes une structure stable, homogène.



   Les   constituants chimiques de    la   madère    plastique jouent un rôle   déterniinfamt,    en ce sens que la rapidité de la polymérisation peut être contr¯lÚe et rendue   telle que les tensions frésultainjtes provoquent    le cra  quètementdelamatièreplastique.   



   Enfin, des   agents thermiques extérioufs à la ma-    tiere plastique peuvent être appliqués, par chauffemen,   t de certaines suràoes    du moule, ou par application de fluides chauds ou froids, pour y provoquer localement des tensions telles que le craquètement se réalise.   



   Dans tous les cas, une armature peut être dncorpo-    rée dans la matière plastique, soit comme un renforcement, la zone   stratifiée dans laquelle tes. tensions    sont neutralisÚes constituant la partie solide de l'objet, soit pouf coopérer à la diffÚrenciation des ten   sions, l'ajmatuTe possédant des caractéristiques diffé-    rentes de la matière plastique.



   On peut utiliser une proportion de 60 à   30 ouzo    de polyester, de 30 à 60    /o    de styrène, de 0, 1 à   5 ouzo    d'un accélérateur et de de   à 8"/o d'un catalyseur.    L'ac  célérateur peut être    de l'octoate de cobalt ou du naphténate et le catalyseur du peroxyde de   méthyl-      éthyl-cétone    ou du peroxyde de benzoyle. 



   Il est bien entendu possible de varier les proportions de styrène ou du catalyseur ainsi que de   modi-    fier la température pour autant que'on tienne, par un choix judicieux de ces éléments, une polymérisation   suffisammentbrusquepourcréerdes'tensions    amenant le craquèlement désiré.



   Les objets en matière plastique ainsi   obtenus peu-    vent tenir lieu d'abat-jour de lampe, pour lampe à pied, de table, à applique ou suspendue. Leur propriété translucide jointe à la coloration possible de la matière provoque des effets esthétiques particulièrement heureux. Cette matière, plastique décorative peut également servir à la fabrication d'objets divers et du revêtement de surface, notamment table, pan  neau,    etc.




  



  Method of manufacturing a decorative plastic element
 The craquelure decoration of a surface of a body has been known for a long time. We know in particular that certain lacquers. applied as a coating have the property of cracking, thus giving the coated object a particular aesthetic effect. Likewise, in the art of glass, it is possible to obtain oraquelements on the surface or in depth and this effect has been applied for a long time for the manufacture of vases, or other interior objects made of glass.



   Until now, however, this effect has not been used for plastics.



   The present invention specifically relates to a method of manufacturing a decorative plastic element living room'lequel which is poured plastic material in a mold having the frome of said element
 This process is characterized by the fact that one chooses the thickness of the walls of this element as well as the physical characteristics of said plastic material so that at least part of the mass is polymerized. of plastic cracks.



   In general, it is a matter of artificially creating internal tensions, preferably on the visible face of the plastic, in order to cause cracking relative to a base layer which must be homogeneous to play the role. support.



  For this purpose, it is possible to polymerize first the base layer and to use a preform or a reinforcement.



   The tensions are a function of the physical characteristics inherent in the manufacture of the elements, namely the thickness of the plastic material, the shape of the plastic material and of the mold, the polymerization characteristics of the plastic material and the thermal agents liable to damage it. influence, taken singly or in combination.



   The thickness of the molded plastic material plays a role in the extent to which it creates locally differentiated plastic polymerization conditions, i.e., for example, faster polymerization of the top layers of the material than of the lower layers. , giving the first unstable structure which results in cracking and the second a stable, homogeneous structure.



   The chemical constituents of plastic madeira play a definite role, in that the speed of polymerization can be controlled and made such that the resulting stresses cause cracking of the plastic.



   Finally, thermal agents external to the plastic material can be applied, by heating certain surfaces of the mold, or by applying hot or cold fluids, to locally cause tensions therein such that cracking occurs.



   In any case, a reinforcement can be incorporated in the plastic material, either as a reinforcement, the laminated zone in which the tires are. tensions are neutralized constituting the solid part of the object, or in order to cooperate in the differentiation of the tensions, the adjmatuTe having different characteristics from the plastic material.



   It is possible to use a proportion of 60 to 30 ouzo of polyester, from 30 to 60 / o of styrene, from 0.1 to 5 ouzo of an accelerator and from to 8 "/ o of a catalyst. can be cobalt octoate or naphthenate and the catalyst is methyl ethyl ketone peroxide or benzoyl peroxide.



   It is of course possible to vary the proportions of styrene or of the catalyst as well as to modify the temperature as long as one maintains, by a judicious choice of these elements, a sufficiently sudden polymerization to create tensions bringing about the desired cracking.



   The plastic articles thus obtained can take the place of lamp shade, for a floor lamp, table lamp, wall lamp or hanging lamp. Their translucent property, together with the possible coloring of the material, causes particularly happy aesthetic effects. This decorative plastic material can also be used in the manufacture of various objects and surface coating, in particular table, panel, etc.
