Definitions

  • the present invention relates to a process for locally mattering a synthetic covering surface, more particularly a floor or wall covering based on PVC and the products obtained.
  • the majority of plastic coatings do not have, on their surface, a sufficient difference in gloss-dullness to give certain areas of the surface a particular appearance.
  • Said zones can for example be a pattern applied by printing on a coating or an imitation of a joint, in the case of a coating imitating a ceramic tile.
  • This process has the drawback of being strongly linked to the graining temperature.
  • a slight overshoot of the temperature may initiate crosslinking at the level of the entire surface of the product, and keep a matt appearance to the entire product.
  • Too low a temperature does not lead to a matt appearance, even at the joints. Given the kinetic aspect of the decomposition of the initiator, a too long graining time, but at the right temperature, risks presenting the same problem (total graining).
  • the present invention relates to an improved method of local matification of a synthetic coating surface which is not linked to the graining or gelling temperature and which is independent of the graining time.
  • the object is achieved by providing a process in which at least one coating or a print containing at least one radiative polymerization initiator is deposited locally on a foamable or non-foamable support and, at least on the entire surface of the support.
  • a coating based on crosslinkable monomer pregelification of the product obtained is carried out after the second deposition at a temperature below the decomposition and degradation temperature of the constituents of said product; graining is carried out at least locally; only the coating containing the crosslinkable monomer is polymerized in the surface covering the radiative initiator under radiation in order to fix its appearance by crosslinking and a gelling is then carried out which, causing the fluidization of the non-crosslinked coating, causes the disappearance grainy appearance in the uncrosslinked surface, and possibly expansion.
  • radiative initiator any suitable initiator which is decomposed or modified by energetic radiation, for example by UV rays, to form free radicals or ions necessary for propagation of chains in a polymerization reaction.
  • an ink or a cut containing a UV polymerization initiator is deposited locally on a foamable or non-foamable support.
  • the method of the invention also has the advantage of allowing road graining the surface of the coating, without having to provide a particular grain roller controlled in accordance with the pattern or the decoration of the coating, since the area which is not polymerized after graining will be fluidized during the subsequent gelation treatment and will be smoothed by surface tension.
  • Particularly preferred compounds are 1,4-butylene glycol dimethacrylate and trimethylolpropane trimethacrylate.
  • the ink containing the radiative initiator may also contain an expansion inhibitor.
  • the ink or the cut obviously does not contain an expansion inhibitor.
  • TMA trimellitic anhydride
  • the products Merck DAROCUR 1173 or DAROCUR e 1116 are preferably used at a rate of 1 to 50%, preferably of the order of 20% by weight, of the ink or of the cut. .
  • the coating containing the crosslinkable monomer contains 1 to 50%, preferably about 11% by weight, of monomer comprising at least two chain propagation sites, optionally in mixture with monomers having a chain propagation site.
  • the support consists of a substrate 1 and a coating at the rate of 500 g / m 2 of a foamable plastisol 2.
  • a coating of foamable plastisol we deposit (Figure 2), in one or more stages, in a first zone, according to a decoration imitating the design of a tiling joint 3, a conventional ink containing an expansion inhibitor and approximately 20% of a UV initiator DAROCUR @ 1173 or 1116 and, according to a decorative pattern any 4, an ink containing a UV initiator
  • the ink can be replaced by a cut, that is to say a solution without dye or pigment, depending on the decorative effects which it is desired to obtain.
  • This deposit is advantageously done by a technique of gravure printing or screen printing.
  • a coating of transparent plastisol, as a wear layer 5, containing an acrylic monomer (ROCRYL 0 980) or another monomer compatible with the chosen initiator is deposited (FIG. 3) over the entire surface.
  • a pregelification is carried out at the usual temperature for this kind of operation, that is to say between 100 and 160 degrees.
  • FIG. 4 represents the graining stage by means of a graining cylinder, over the entire surface, at a temperature usually practiced for this operation, that is to say at a temperature above 100 ° C. pressure depending on the desired degree of dullness.
  • the pre-gelation and graining steps can be carried out in a single step, using an adequately heated graining cylinder.
  • Passage under a UV lamp 7 makes it possible to crosslink the area containing the U.V. initiator so that the (grained) state of this area is fixed by the crosslinking.
  • the product obtained is passed, for 1 minute to 2 minutes 30 seconds, in an oven at approximately 200 ° C., intended to expand the foamable coating 2 in places which do not contain an expansion inhibitor to be gelled and to fluidize the zone which has not been polymerized during the UV initiation by causing a fluidification which has the effect of smoothing the grained surface, while the grained and crosslinked zone during the UV initiation maintains its grainy state (mat ).
  • the product shown in FIG. 6 is obtained.
  • the pregelling is advantageously carried out on a cylinder at 130 ° C., this temperature can even be exceeded as a function of the running speed of the product.
