Description

Manufacturing method of non-composite composite panel having artificial marble at the edge and non-composite panel manufactured thereby {Fire-resistent composite panel having artificial marble}

The present invention relates to a non-combustible composite panel, in particular, has a lightweight structure, the raw material cost and easy processing, the overall manufacturing cost is reduced, the surface strength and heat resistance of the fire resistance is very excellent, and the appearance is refined and luxury and At the same time, it is beautiful because it can express various colors, and the design can be changed in various ways.

Originally used for furniture and interior decoration, panels are made of wood (plywood, MDF, PB) with a separate edge finish (aka: edge) made of PVC, PP, PET, ABS, aluminum, etc. It is produced by gluing.

This method is suitable for mass production of furniture and building interior materials, and it is easier to produce than the paint painting method, which is a long production method of furniture production.However, the adhesive strength is weak by attaching film paper or injection plastic to wood with adhesive. Falls, and there are many environmentally harmful plastics.

In addition, the urethane top plate is a manufacturing method that is more advanced than the film adhesion method such as PVC and PP, and the edge part is inserted into the mold and injected into the urethane foamer, so that the product is excellent. It takes a lot and has the disadvantage that the color is limited to gray and black.

On the other hand, in recent years, a lot of non-composite panels that do not need an edge on the edge of the panel has been developed. Looking at the configuration of a panel called a compact board (compact board) or CMP (compact melmaine panel) as a kind of such a non-composite panel , Multilayers impregnated with thermoplastic resin on fabric or paper (kraft paper), and the non-combustible panel layer (core layer) of a certain thickness by pressing a non-combustible material, a heat insulating material or an inorganic material layer at a high temperature and high pressure inside It is formed by attaching a surface layer printed on both front and rear surfaces of the non-combustible panel layer (core layer) and a thin non-combustible panel paper having a protective layer protecting the printed surface layer.

The non-composite panel, called the compact board or compact melmaine panel (CMP), has a higher density, higher surface strength, higher scratch resistance, and excellent non-combustibility, compared to conventional melamine cosmetic panels. While the impact resistance and dimensional stability has an advantage, while the tissue is made of too dense high density has a disadvantage of heavy weight, there is a disadvantage that is not easy to handle.

In addition, there is a disadvantage in that the manufacturing process is not easy and the manufacturing cost is very expensive.

Therefore, rather than using thick boards or CMPs that are thicker in recent years, compact boards or thinner boards made of CMP with a thickness of 3 to 5 mm are attached to both the front and back sides of plywood or synthetic resin boards to be used for furniture. I can see that.

Meanwhile, recently, furniture panels are manufactured using artificial marble, for example.
