Problems solved by technology

This multi-layer material must rely on multiple reinforcement materials while reducing the thickness of the stone, and there are still problems that hinder its use in everyday life equipment
[0006] Furthermore, the multilayer material described in document WO2009142365 A1 has limited applications, since this multilayer material has to be sandwiched on top of another material
The fact that the backing layer uses an interlocking system limits the application to floor and wall decorations

Embodiment 1

[0080] We produced as figure 1Described multilayer material, to obtain a 100cm * 115cm big, 8.25mm thick material, this material is made of 6mm thick gray marble 1, 0.25mm thick two-component epoxy adhesive layer 3 and 2mm thick muscovite layer 2 composition. We first glued a 18mm thick, 100cm x 120cm large marble 1 on its two larger surfaces with two separate 100cm x 120cm large, 2mm thick mica layers 2, each made of 10% epoxy adhesive And muscovite-type mica flakes. Then we use 400N / m 2 The glue was pressed and cured at room temperature for 6 hours. The glue we use is a two-component glue with a viscosity of 10,000cps to 14,000cps and a solid content of 95%. We then sawed the multilayer material by cutting the marble from its edge with a diamond saw at a speed of 0.5 m / min to provide 2 pieces of marble-mica layer multilayer material 1 of 100 cm x 120 cm. We then ground stone layer 1 and polished it to give each layer a smooth and adjusted surface thickness.

Embodiment 2

[0082] We produced as image 3 Described multilayer material, to obtain a 20cm * 115cm big, 16.15mm thick material, this material is made of 6mm thick gray marble 1, 0.15mm thick two-component epoxy adhesive layer 3 and 10mm thick muscovite layer 2 composition. We glued a 18mm thick, 100cm x 120cm large marble 1 on its two larger surfaces two 10mm thick mica layers 2 consisting of 12% epoxy adhesive and muscovite mica flakes . Then we use 400N / m 2 The glue was pressed and cured at 20°C for 24 hours. The glue we use is a two-component glue with a viscosity of 10,000cps to 14,000cps and a solid content of 95%. We then sawed the multilayer material by cutting the marble 1 from its edge with a diamond saw at a speed of 1 m / h to provide 2 pieces of marble-mica layer multilayer material of 100 cm x 120 cm. We grind and polish the stone layer 1 to provide a smooth and adjusted surface thickness. We then cut the obtained multilayer material into pieces of 20cm x 115cm with a sto...

Embodiment 3

[0085] We performed impact tests on several samples to evaluate the crack resistance of some embodiments of the present invention to compare their performance with samples of stone thicknesses and stone-honeycomb aluminum and stone-PVC multilayer material structures commonly found in the market .

[0086] We evaluated the fracture resistance of the samples by gradually dropping spherical steel balls from gradually increasing heights on the stone surface of the samples and observing whether the stone tile layer cracked. With the exception of 2 modifications to increase the relevance of the test results to the material of the invention, we carried out the conditions described in the standard EN 14617-9:2005 (Impact resistance of flat products made of reconstituted stone) experiment method. These two modifications in the EN 14617-9:2005 test method are:

[0087] 1. The test method described in EN 14617-9:2005 considers hitting the center of the sample accurately at the same poi...

Abstract

The present invention relates to a multilayer material comprising a layer of stone (1) laminated to a layer of reinforcing element (2) and its manufacturing process.

Description

technical field [0001] The invention relates to a multilayer material comprising a layer of stone laminated to a layer of reinforcing elements and a method for its manufacture. Background technique [0002] Stone is commonly used in equipment used in construction, transportation or daily life (such as decorative panels and floors), interiors of business aircraft and ships (such as tables, floors and panels), smartphone casings, mobile power casings or It even brings a luxurious temperament in the furniture. Unfortunately, using this stone is very time-consuming and user-unfriendly through the use of heavy stone bricks, cement for flooring applications, or when the stone is used in equipment or transportation. When stone has to be moved or placed when used in construction, it requires many precautions and steps. To facilitate the use of stone, it is necessary to reduce the thickness of the stone, especially when it comes to daily life equipment, but the fragility of the sto...
