Description

FLOOR AND WALL COVERING

WITH CONTRAST SHINE

  The invention relates to the technical sector of floor and wall coverings and more particularly to the rendered gloss effects, a particular characteristic for enhancing the relief effects and

of aesthetics sought.

  The multiplicity of floor and wall coverings existing on the market meets the requirements of customers with varied tastes looking for relief effects, and designs having in particular very realistic renderings

  obtainable by different matte and shiny effects.

  To implement such coatings, different technologies exist. We know, for example, patent WO 99/39042 which describes floor and wall coverings with contrasting gloss effects containing one or more layers with particles such as alumina. This described method involves the use of a crosslinkable resin based on urethane. This process requires chemical graining and provides a partial coating layer applied by roller on the reliefs of the product and having a difference in gloss to create a contrasting effect. In practice, this

  technology is difficult to implement.

  Also known, from European Patent No. 1149712, is a process for producing floor and wall coverings with decorative effects of differential gloss, under the terms of which an underlying coating is produced and gloss effects are produced by differentiated deposits without overlap. total of at least two layers of protection of different characteristics, whether or not in register with the underlying decor The technique described in the aforementioned patent has drawbacks in that it requires at least two superimposed steps with, at a minimum, two different gloss layers of satin and gloss for example. In addition, the products used, according to this exploited process, reveal a serious defect, namely the difficulty of framing by the register of the zones of overprints in relation to the decoration to be closed or to let appear according to the effects.

  research. This is seen by a misalignment of the masking effects.

  Furthermore, the geometric shapes of the drawings or patterns to be reproduced with the differentiated gloss effects are limited to the basic geometric shapes due to the design of the registers. We are also faced with a problem of deterioration due to wear and fouling. Indeed, the upper protective layer can be deteriorated and the aesthetic aspects sought initially destroyed or

  partially or completely deleted.

  The aim sought after, according to the invention, is to remedy these drawbacks by proposing a new simplified implementation method which guarantees the obtaining of a constant finish of high quality and reproducibility. Another sought-after object, according to the invention, is to implement a new process which overcomes the constraints, shapes and dimensions of the drawings and patterns thus contributing to widening, so

  substantial and almost unlimited, the choice of designs and patterns.

  Another goal is to overcome any problem of misalignment. These and other goals will emerge well from the rest of the

description.

  According to a first characteristic, the method is remarkable in that it comprises: - a first assembly (GI) composed of one or more layers of plastic coating of the ground to be protected, - a second assembly (G2) receptor of reflective particles and allowing a reflection of light, said particles being distributed in a homogeneous or arbitrary manner, - at least one masking means added or projected onto the upper face of said second set by defining opaque zones, translucent zones, transparent zones or free zones masking, and in that the connection between the first and second sets is ensured by

any means.

  - a third set (G3) of surface covering the second

  together for the purpose of protecting the masks obtained.

  To fix the object of the invention, it is now described in a nonlimiting manner illustrated in the figures of the drawings o - Figure 1 is a schematic view of a floor or wall covering implementing the method of the invention in a first alternative embodiment, the masking being carried out by printing technology. Figure 2 is a schematic view of a floor covering or wall implementing the method of the invention in a second embodiment, the masking being achieved by printing technology. In order to make the object of the invention more concrete, it is described

  now in a nonlimiting manner illustrated in the figures of the drawings.

  The covering of floors or walls made of plastic material comprises, according to the invention, at least three sets of layers, namely: - a first set (GI) composed of one or more layers of plastic covering of the floor, implemented by known manner as a back side and one or more additional layers of all

  characteristics, by any known manufacturing process.

  - a second set (G2) receiver of reflective particles

  and allowing the reflection of light and being able to receive masks.

  - a third surface assembly (G3) covering the second assembly (G2) over all or part of its surface for the purpose of protecting

masks obtained.

  The second set can consist for example of a layer

  plastisol, or other materials, by any known manufacturing process.

  Said reflecting particles can be brought either directly into the mass of the plastisol layer, or laid by dusting or spraying on the surface of said plastisol layer, or laid by printing. These particles are metallic or otherwise for

  ensure the desired light reflection effect.

  According to the invention, said reflective particles are capable of being masked in one or more zones by a specific masking means which makes it possible to vary, according to the needs and the desired contrast effects, in matt or gloss, the final appearance. of the coating. Thus, according to the invention, and in a first variant, the masking means can be a transparent, translucent or opaque layer, colored or not, containing particles or not, and deposited by printing, or other technique, or a pre-film. -mask. This layer can have opaque zones, translucent zones, transparency zones or zones where there are no masks. We have successively represented them ZI, Z2, Z3, Z4. We thus create various effects of shine without being limited in

  the choice of shapes, contours and dimensions of each of the above areas.

  As a variant, the masking means can be implemented by a simple opaque or translucent printing by the addition of projections or dusting, non-receiving opaque translucent printing areas, remaining

  directly visible externally.

  There is shown, Figure 2, an alternative embodiment of the invention in which we wanted to accentuate the enhancement of relief effects. For this, the first set (GI) is established in a known manner with one or

  several layers, as previously indicated.

  The second set (G2), receptor of reflective particles, has a foam-like layer structure with the implementation on the visible surface, opposite the first set, with the effects of successive planes staged thanks to the use of inhibiting agents or expansion catalysts known per se. In the example illustrated, there is thus obtained a succession of planes at different levels and which may have various shapes and dimensions. The reflecting particles are distributed homogeneously or not throughout the surface of the layered structure or in

its thickness.

  Furthermore, as before, a masking means makes it possible to differentiate opaque, translucent, transparent areas and areas free from printing. The masking means may be a surface layer or varnish or be constituted by simple projected prints or

  by dusting on the places to hide.

  The third assembly group (G3) can be established in the form of a film or layer to cover the second assembly group (G2) for the purpose of protecting and maintaining the masks obtained. The thickness of this group

  overall (G3) is variable as required.

  Without departing from the scope of the invention, the set groups (G2) and (G3) can constitute a single set which brings together all the

  properties specific to each set.

  The method of the invention is therefore simplified compared to the prior art and allows greater flexibility of implementation with gloss effects rendered on areas of very varied dimensions and configurations, simple or complex, by eliminating the problems. misalignment. The connections of the sets GI and G2 on the one hand, and G2 and G3 on the other hand, are established in any suitable manner known in the field of the design of floor coverings. The arrangement of the reflecting particles in or on the receiving layer (G2) can be established from

  homogeneous or varied depending on the desired effects.
