Artificial stone may be used for building and furniture applications. Patent application number 2454/CHE/2008 titled “Body Structure For Furniture And Building Structures”, filed on 6 Oct. 2008 in the Indian Patent Office, coauthored by the applicant refers to the use of artificial stone in door and table applications.
Conventionally art work is created on a work bench. The making of a piece of artwork takes a long time depending on the skill of the artists. Hence there is a need for preparing the art work in a remote site and creating artwork rapidly. Furthermore, the created art work needs to be transported to the work bench for integration into the artificial stone without disturbing the art work during transportation. Hence, there is an unmet need for a convenient process that enables the infusion of art into artificial stone surfaces for furniture and building structure applications.
This summary is provided to introduce a selection of concepts in a simplified form that are further described in the detailed description of the invention. This summary is not intended to identify key or essential inventive concepts of the claimed subject matter, nor is it intended for determining the scope of the claimed subject matter.
The method disclosed herein address the above stated need for a convenient process that enables the infusion of art into artificial stone surfaces for furniture and building structure applications.
The method disclosed herein enables the manufacture of a decorative surface of a furniture body or building structure. A layer of an art release sheet is manufactured with multiple art units adhering to a surface of a base sheet. The art release sheet is manufactured by applying a binder on multiple predetermined regions, selected surfaces, or the entire surface of the base sheet. The art units are placed on the binder, whereby the art units adhere to the base sheet. The art units are, for example, one or more of ornamental glass, semiprecious stones, metal art, colored quartz, glass jewelry, stone jewelry, etc. The binder is, for example, polyvinyl alcohol. The binder may be dried at room temperature or at an elevated temperature. The art release sheet is transported to a work bench without dislodging the art units from the base sheet. The base sheet is, for example, a polyethylene terephthalate sheet, a plastic sheet, a rubber sheet, or a polytetrafluoroethylene (PTFE) sheet.
An uncured artificial stone mix is deposited on the art release sheet and compacted. A central core is placed on the art release sheet deposited with the uncured artificial stone mix. The surface of the central core comprises one or more of a planar surface, a curved surface, an uneven surface, a non uniform surface, and a combination thereof. The art release sheet with the uncured artificial stone mix is wrapped around the central core, whereby a contiguous piece of art work extending from one face of the furniture body or building structure to one or more of another surface of the furniture body or building structure is created. The artificial stone mix is allowed to partially or fully cure. The base sheet is removed after allowing the artificial stone mix to partially or fully cure. The strength of adhesion between the partially cured or the fully cured artificial stone mix and the art units is greater than the strength of adhesion between the art units and the base sheet. The art units are embedded in the cured artificial stone mix, whereby the decorative surface is manufactured.
In an embodiment, a method of manufacturing a decorative surface of a furniture body or building structure comprises: a) manufacturing an art release sheet, wherein the art release sheet comprises multiple art units placed on a surface of a base sheet; b) depositing an uncured artificial stone mix on the art release sheet and allowing the uncured artificial stone mix to partially or fully cure, whereby the art units are embedded in the cured artificial stone mix for manufacturing the decorative surface.
In another embodiment, the art release sheet with the uncured artificial stone mix is wrapped around a central core placed on the uncured artificial stone mix to create a contiguous piece of art work. The contiguous piece of art work extends from one face of thee furniture body or building structure to one or more of another surface of the furniture body or building structure. The base sheet is removed after allowing the artificial stone mix to partially or fully cure.
In yet another embodiment, a method of manufacturing a decorative surface of a furniture body or building structure comprises: a) manufacturing an art deposit frame for creation of an art unit, wherein the art deposit frame comprises a cavity defined by a continuous sidewall and a wire mesh detachably attached to bottom edges of the continuous sidewall, wherein the continuous sidewall defines a periphery of the art unit; b) loading the art deposit frame with art particles of a predetermined quantity and size; c) placing the loaded art deposit frame on a base layer, wherein the base layer has a surface release property; d) vibrating the loaded art deposit frame on the base layer, thereby allowing the art particles loaded in the art deposit frame to pass through the wire mesh of the art deposit frame to create the art unit rapidly on the base layer; e) depositing an uncured artificial stone mix on the base layer comprising the created art unit; f) compacting the deposited uncured artificial stone mix and allowing the compacted artificial stone mix to partially or fully cure, whereby the created art unit on the base layer is embedded in the cured artificial stone mix for manufacturing the decorative surface.
After depositing the uncured artificial stone mix on the base layer, pressure is applied on the deposited artificial stone mix. A backing of glass fiber is applied on the deposited artificial stone mix and coated with a resin thereby providing improved strength to the furniture body. Vibro-compaction or vibro-compaction in a vacuum is applied to the artificial stone mix, whereby trapped volatiles and air are released.
The foregoing summary, as well as the following detailed description of the invention, is better understood when read in conjunction with the appended drawings. For the purpose of illustrating the invention, exemplary constructions of the invention are shown in the drawings. However, the invention is not limited to the specific methods and instrumentalities disclosed herein.
An uncured artificial stone mix 301 is deposited on the art release sheet 200, as exemplarily illustrated in
In an embodiment, the base sheet 202 may be a cellulosic paper based sheet. In case paper is used, the base sheet 202 may be retained after the deposition of the artificial stone mix 301. The paper layer is abraded and removed during the final surface polishing of the cured artificial stone mix 301. If the base sheet 202 is a plastic sheet, the base sheet 202 is released from the cured artificial stone mix 301.
The artificial stone mix 301 further comprises particulates and resin. The particulates are composed of quartz, or composed of one or more of quartz, granite, glass, ceramic, etc. The size of particulates may vary from a fine powder to about 4 mm. The size distribution may follow Fuller's formula to achieve maximum compaction. The resin is, for example, a polyester resin. An example of a polyester resin is a combination of about 80% of an unsaturated polyester resin such as ortho neo pentyl glycol and about 20% of styrene monomer. Another example of a polyester resin is a combination of ortho neo pentyl glycol, methyl acrylate, and styrene monomer. Room temperature catalysts, for example, methyl ethyl ketone peroxide (MEKP) and room temperature accelerators, for example, cobalt naphthenate may be used for curing the resin. In another embodiment, high temperature setting catalysts, for example, dimethyl aniline (DMA) may be used for curing the resin. The artificial stone mix 301 may also be a cement based mix.
Examples 1, 2 and 3 are example compositions of an artificial stone mix 301.

This example illustrates the manufacture of a furniture body 600, for example, a table top. A base release layer, polyvinyl alcohol (PVA) is coated on a surface. An art deposit frame 1000 as exemplarily illustrated in
The artificial stone mix 301 may be subjected to vibro-compaction. Vacuum may also be applied for better compaction and removal of trapped volatiles and air. The compacting pressure may be applied by a heavy roller. Pressure in the range of, for example, 1 kg/cm2 to 10 kg/cm2, may also be applied using a vibrating compactor, wherein the compactor is a hydraulic or a pneumatic compactor.
Finally, the surface of the furniture body 600 is polished by the polishing techniques applied in granite polishing.
In another embodiment, uncured artificial stone mix 301 is compacted and a layer of fiber deposited on the compacted layer and coated with a resin. In yet another embodiment, a metal grid is inserted in the central core 401.
In yet another embodiment, the binder is a wet binder. The binder is, for example polyvinyl alcohol (PVA). Polyvinyl alcohol is herein referred to as PVA. The liquid PVA is applied to the base sheet 202 as a coating. The art units 201 are placed on the PVA coating, and the PVA coating is allowed to dry at room temperature or dried at an elevated temperature to enable the art units 201 to adhere to the base sheet 202. The art units 201 comprise, for example, one or more of ornamental glass, semiprecious stones, metal art, colored quartz, glass or stone jewelry, etc. Examples of the furniture body 600 or building structure include tables, doors, kitchen cabinet faces, flooring etc.
In yet another embodiment, a wet binder such as PVA is applied on the base sheet 202. The art units 201 are placed on the applied wet-binder and the wet binder is dried using a dry blower or a hot air dryer, thereby creating an art release sheet 200 in a much shorter duration of time.
A backing of glass fiber is applied on the artificial stone mix 301 and coated with a resin thereby providing improved strength to the furniture body 600. Vibro-compaction or vibro-compaction in vacuum is applied to the artificial stone mix 301, whereby trapped volatiles and air are released.
In yet another embodiment, an art unit template has a cavity with a contour of the shape of the art unit 201. The art unit template is shaped from a material such as a foam and placed on the base sheet 202. The art particles 1101 are deposited in the cavity of the art unit template and vibration is imparted to the art unit template to distribute the art particles 1101 evenly on the surface of the base sheet 202. The vibration causes the deposited art particles 1101 to conform to the contour of the art unit 201 defined by the contour of the art unit template, whereby the art unit 201 is created rapidly.
