Benefits of technology

[0004] The object of the present invention is to provide a composite lamina which is relatively inexpensive to manufacture and provide a simulated natural stone-like appearance.
[0005] The main advantage of the present invention is the backer layer, more specifically a cement board panel who gives over other solutions offered today a very good adhesion for the organic portion, better strength for the same thickness, and a very economical way to make stone-like panels. For example, at an equal strength, it is more economical to put a cement board backing with a thinner layer of polymer than no backing and a greater amount of polymers.
[0006] By utilizing the process of the present invention, various solid surface decorative articles can be provided having a myriad of aesthetic designs. Moreover such process is economical and capable of mass production. Also, highly detailed inlays may be produced from engraved cement board backing with one or more color as inlays. Final product may have embossed surface made by the embossed and / or engraved cement board.

Problems solved by technology

For the most part, these products are expensive because acrylic panel need a lot of polymer.

Embodiment Construction

[0007] The present invention proposes a cement board as a backup layer. Hard surface of cement board provide a very good substrate for engraved and / or embossed high precision pattern. Cement board are corrosion resistant and maintenance cost is minimal. Cement board provides high rigidity and stiffness at low cost.

[0008] The present invention is impact resistant, termite and vermin resistant highly fire-resistant, moisture resistant and it provides to the final product very good and economical structural qualities and it is perfect for interior / exterior application such as wall panels, balconies and decks.

[0009] The present invention decrease the needs of polymer material without affecting the strength of the product, therefore the present invention gives a low cost versus strength ratio.

[0010] The present invention provides a high strength-to-weight ratio which enables the resin layer to be thinner without sacrificing mechanical strength characteristics.

[0011] The present inven...

Abstract

The present invention provides a laminate which has a stone-like appearance comprising a fiber cement board. The cement board layer can be embossed and / or engraved and / or painted to give the impression of colors and depths. Organic polymer composition which includes inorganic filler is included in the laminate.

Description

BACKGROUND OF INVENTION [0001] The present invention relates to sheets and slabs of acrylic solid surface now commonly used as kitchen countertops, interior and exterior decorative coverings and architectural panel. Since the early 1980's, several major manufacturers have developed their own brand of solid surface products. For the most part, these products are expensive because acrylic panel need a lot of polymer. The present invention can create the appearance of granite, marble or other types of stone surfaces. The present invention show superior hardness, high structural toughness at a low cost when compared to other acrylic solid surfaces or other stone-like laminates products. [0002] Other processes have attempted to reduced the cost of acrylic panel. Several such prior art teachings are shown in U.S. Pat. No. 3,963,846 proposes a backing sheet consisting of a multicellular resin-impregnated paper core. This layer is made partially of polymer and the cost of this products is f...
