Description

A COMPOSITE STONE SLAB HAVING MARBLE APPEARANCE
Field of the Invention
The present invention relates to composite stone slabs having marble appearance but are more lightweight than marble, developed to be used in decorative and durable surfaces in construction sector and a method for production thereof.
Background of the Invention
Today, products with marble appearance are obtained by mixing natural quartz mineral extracted from underground with specially developed polyester resin. It is produced by being designed with pigments of different colors and quartz granules of different sizes, shaped upon being casted in slab shaped molds and then oven-dried.
Quartz is the name given to the quartzite, silica, silica sand, pure silicon dioxide (Si02) crystals. Quartz is used as the mineral name. Quartz, which crystalizes in the form of a hexagon, may be in the form of crystal or an amorphous form in the nature. According to the type and amount of the foreign material therein, it is colored or semi-transparent. Today, quartz is transformed into different products by modern technology for use in different fields. Kitchen and bathroom counters and floor covering are several areas wherein quartz is used. In these kinds of products, minimum 93% of the content is comprised of quartz, small amount of polyester resin binder or white cement binder pigments. Nowadays, the closest products which are used as alternative to granite and marble are quartz composite stones.
The prior art includes marble-like products obtained by composition off the quartz with different materials. For example, the patent document no. CN108033741 A discloses a production method of a marble-like surface material. Mainly quartz, aluminum cement, pigment and sodium silicate solution are used; the mixture prepared with these are poured into molds, and upon curing of the mixture for 1 -2 hours, composite stone slabs are obtained. It is disclosed that the slabs prepared with this method are shiny (glossy), smooth and durable.
The state of the art also includes production of composite stone slabs with materials that are alternative to quartz. The document no. TR2017/02443 discloses use of stones comprised of basalt, corundum (emery stone), granite, bauxite (diasporite) and olivine instead of quartz in construction sector in the production of composite stone which can be used in floor and wall coverings, especially kitchen countertops and bathroom counters in different slab sizes.
When the natural stone slabs developed for use in decorative and durable surfaces in the current art are examined, it is observed that those having marble appearance are heavy due to quartz use, and when more lightweight natural stones are used instead of quartz, the strength decreases.
Considering the problems described above and the materials used in counters and coverings made of natural stone, it is seen that the improvements that are made are insufficient. Today, there is still a need for composite natural stone slabs which, in addition to having a marble appearance, are both lightweight and scratch-resistant, and development of their production methods.
Summary of the Invention
The present invention relates to an upper product range which meets the abovementioned requirements, eliminates all of the disadvantages and brings some additional advantages.
The composite stone slab having marble appearance is developed for use in decorative and durable surfaces in construction sector and provides a more lightweight structure than marble and quartz based composite stone slabs.
The primary object of the present invention is to provide a composite stone slab which has a marble appearance and strength and which is made more lightweight and brightened. Another object of the invention is to provide a composite stone slab basically comprising cristobalite instead of quartz in order to obtain the appearance of marble.
Another object of the invention is to provide an opacified composite stone slab by means of the zircon compound in its content.
Another object of the invention is to provide a composite stone slab production method wherein molding is carried out by the processes of vacuum, pressing and vibration.
To achieve the above-mentioned objects, the present invention is a composite stone slab which provides marble appearance and comprises at least one opacifier and at least one resin and comprises cristobalite.
In order to fulfill the objects of the invention, the invention comprises 75-88% by weight of cristobalite, 10-20% by weight of resin, and 1 -10% by weight of opacifier. The opacifier mentioned herein is preferably zircon compound.
The invention further comprises at least one pigment for achieving its objects, wherein the preferred pigment ratio is 1 -5% by weight.
The present invention is the production method of the said composite stone slab comprising the process steps of
(i) Mixing cristobalite with at least one resin and at least one opacifier;
(ii) pouring the mixture into a mold and pressing it by vibration under vacuum;
(iii) curing the pressed mixture with exothermic reaction.
Here, in the process step (i), 75-88% by weight of cristobalite, 10-20% by weight of resin, and 1 -10% by weight of opacifier are mixed preferably with a zircon compound. In a preferred embodiment of the invention, at least one pigment is added and stirred in the step of (i). The preferred pigment ratio is 1 -5% by weight of the total mixture. In the method of the present invention, the mixing process in the process step of (i) is performed at 90-200°C for 30-60 minutes.
In the method of the present invention, in the process step of (ii), the mixture is pressed by vibration under vacuum at a pressure of 100 tons for 3-10 minutes.
In the method of the present invention, the temperature of the curing disclosed in the process step of (iii) is 80-120°C.
After the process step (iii), the method of the present invention further comprises cooling the cured composite stone slab and polishing the surface thereof by the help of diamonds or an abrasion machine.
The structural and characteristic features and all the advantages of the invention will become apparent from the detailed description given below. For this reason, the assessment should be made taking into account the detailed description.
Detailed Description of the Invention
In this detailed description, the preferred embodiments of the inventive composite stone slab having marble appearance are described only to facilitate better understanding of the invention without producing any limiting effect.
The invention is a composite stone slab with marble appearance and basically comprises cristobalite, resin and opacifier.
The composite stone slab of the present invention is in the form of a slab having an opaque, shiny, smooth, veined marble appearance for use in decorative and durable surfaces in construction sector, especially kitchen countertops, bathroom counters, floor and wall coverings.
While the marble appearance and strength is provided by quartz in the state of the art, these features are provided in the present invention by cristobalite. Cristobalite is a chemically inert product with a high degree of purity and whiteness which is formed by calcination of silica at high temperature. While it has the same chemical formula with quartz, its crystalline structure is different from quartz. This difference enables cristobalite based slabs to have a high gloss surface. While density of quartz is 2.65 kg/dm3, density of cristobalite is 2.30 kg/dm3. Therefore, the composite stone produced with cristobalite raw material is more lightweight.
