others for floor coverings and cladding in general, such as interior and exterior cladding panels for residential buildings, decorative panels, panels for tables and furniture and the like. Which is characterized in that it consists of a basic structure in which a mother-of-pearl-like material different grain composition is incorporated

According to the invention, it has been found that the mother-of-pearl-like material not only gives the plate a special aesthetic effect, but also gives it better technical properties.

Other features and advantages of the invention are more apparent the following description of some examples of additional sets of the panel element according to the invention, which for example and without being restricted to this, are described with reference to the accompanying drawing in which the Flg. i in a perspective view Example of a plate element according to the invention «eigt and the Pig. 2 the Representation of an execution variant of the panel according to the invention is shown.

23.5 kg of mother-of-pearl sand with the following grain composition, expressed in The mean particle diameter is 6.5 kg, grain size 2mm, grain size 3kg 3mm, 3 kg grain 4mm, 3kg grain 5mm, 8 kg grain 6mm; 0.2 kg of Choppestrand fiberglass and 4.25 kg of a polyester resin (in an experiment the resin known in the trade under the name Gabraster, Type 1403, was successfully used, and in another attempt that was also successful under the Resin known as Sirester FS 10 or 313, all of which are manufactured by Montecatini Edison SpA Milan, Italy A diluent suitable for the resin, which in one experiment was styrene, in an amount of 0.5 kg and a Accelerator added, which in a test carried out was 6 percent Koba'itoctoat in an amount of 0.030 kg. It became further a Catalizer added, which in one of the experiments consisted of paste-like benzoyl peroxide · Furthermore, 0.1 kg of glass splinters with grain dimensions of 0.01 cm in diameter and 0.1 kg were successively added. kg of glass powder that previously with a 40 percent aqueous solution of hydrochloric acid was added. In one of the tests, 0.045 kg was also plasticized liquid steel added, which had been chemically converted into the liquid state and is known in Hendel under the name Devcom.

The mixture thus prepared was then mixed uniformly by mixing in a mixer or kneader such as a screw-type kneader.

For the purpose of forming the plate was in a frame or in A fora first formed a pure, transparent resin, after which Pieces of pearl nut from the grain growth of 5-6 mm in diameter.

were brought, taking into account that they were flattened and the shiny side Was visible over a thickness of about 1 cm. Then made the shape in the desired strength with the prepared mixture ordering from the above-mentioned ingredients with mother-of-pearl various Felt grain composition.

In the course of this so-called "cold processing", i.e. processing at a temperature within 27-30 ° C, you can have a Produce variety of panels of different dimensions, one of which shown schematically and in perspective in Fig. 1 of the accompanying drawing is. In this drawing, 1 designates the plate in which Basic structure 2, consisting essentially of resin and lime powder with ground oysters in finely powdered form, pearlescent granulated Material 3 is incorporated, which is distributed in the structure and on the The outer surface la of the plate is visible and has a remarkable aesthetic » see effect causes. In particular, the first allows pure and transparent Resin layer and the layer of mother-of-pearl pieces facing outwards shiny side achieving the desired results.

According to another embodiment, the above composition becomes the lime and dyes are omitted and the plate is made with pure Resin and made with mother-of-pearl to make them transparent and to make the pearlescent material visible even in a great depth of the thickness of the plate. J i

According to another embodiment, the formation of the first is known Pure and transparent cure layer are omitted, with the first layer being below the layer on the bottom of the form su i * t understand which at pavers

finished panel forms the upper or visible layer of the same, which is then finely ground and / or polished in a suitable manner.

Example 2

The same composition as in Example 1 was prepared with the Exception that the mother-of-pearl sand forming the upper layer is replaced by a appropriate amount (19 kg) of marble was replaced, forming squares or rectangles different dimensions was cut, which subsequently vorssugswe.isa in the formation of the plate vorssugswe.isa in the visible surface of the same were ordered. The plate was formed in the manner indicated above, i.e. with frames or molds, the panel obtained is schematic and First shown in perspective in Fig. 2 are the precut rectangles arranged with a gap between one and the other rectangle is released. The mold is then filled with the prepared mixture, which penetrates the crevices in the semi-liquid phase and fill it in · Like the drawing figure. 2 can be clearly seen, take those marked with 5 and in their quality and dimensions pre-selected marble rectangles in a position in the field of vision the plate and it is thanks to the irregularity of the dimensions of this Rectangles or squares are the "composition" of a panel or one Flooring made easier by using a variety of panels 4 * Next is in the visible area between a marble rectangle 5 and des | adjacent there is an outline 6 in which the mother-of-pearl material is with a smaller grain composition, whereby a surprising aesthetic effect is obtained and you get rectangles graze firmly anchored.

Example 3 :

The composition given in Example 1 was formed, after which Plates using the so-called "commodity processing" with a Special presses were formed that operate at approx. 240 ° C and at pressures of About 70-100 kg / cra ^ work · This accelerates the polymer dissolution and reduces the hardening time to approx. 1 hour.

In this way, processing with increased productivity figures was achieved and panels were obtained from both that in Example 1 as well as of the type described in example 2, with a different material than marble being used as rectangles or squares.The slabs had inherent characteristics and aesthetic properties that were completely comparable to those of the slabs that were manufactured in the course of processing according to the previous examples were and one corresponded to the main objectives of the invention.

_Λ Example 4 :

The composition geoSsa Example 1 was produced, but with the basic resin structure with a structure of cement in a suitable amount

Use of a type 1000 cement, i.e. with a nominal pressure

2 strength of 1000 kg / cm, was replaced. Then both with the Hand made as well as faceplate panels that are more old satisfied presenting properties corresponding to the objectives of the invention.

If, for reasons of use, it was necessary to add a

to communicate particular coloring, so were the compositions of the preceding Examples of known agents and dyes added in the amount corresponding to the intensity of the desired color, such as for example metal oxides (iron oxides, chromium oxides).

If the panels are to be used as a floor covering, the lower surface is left a little rough (Fig.l), whereas the lower surface is used when it is used of the plates as tablecloths or furniture cladding in general has no substantial roughness, as can be seen, for example, from FIG is.

In particular is. it is also possible to produce decorative panels, which are formed from different layers, with the visible effect remains unchanged, and the underlying layers in a suitable manner be put together to suit them to their intended uses adapt.

After long and controlled trials it was found that with the plates according to the invention that in the examples specified composition, the objectives set out at the beginning were fully achieved, i.e. that the plates were wear-resistant, a Resistant to external and atmospheric influences, easy could be put together and a very effective aesthetic look The invention described above can be varied in many respects and can be changed without going beyond your limits · In particular the individual parts and dimensions, such as the grain addition ■ aomenseffzung of the materials used, can be selected as required, depending on the requirements.
