The present invention relates to a method of manufacturing artificial marble furniture tops, and more particularly, to a method of manufacturing artificial marble furniture tops having a variety of appearances and luxurious natural textures such as natural marble up to the edge of the furniture tops. .

Natural marble, which is formed by recrystallization after lime or dolomite is subjected to contact or wide-area metamorphism, has a unique multicolored pattern and gloss when polished, and is used as interior and exterior materials of buildings. However, the building material made of natural marble has a problem that its use is limited because its thickness is usually 10 mm or more, its volume, weight, and price are high. Thus, although the price is lower than that of natural marble, much effort has been made to manufacture artificial marble that can give the impression of natural marble.However, various appearances and luxurious textures such as natural marble extend to the edges of furniture tops. The real marble furniture tops have not been developed yet.

Thus, the present inventors have developed the artificial marble furniture top plate having various appearances and luxurious textures such as natural marble to the edge to complete the present invention.

An object of the present invention consists of a panel with a marble pattern / pattern layer of unsaturated polyester resin, pearls and waxes on the top and / or bottom and edges, and a variety of appearances and luxurious textures such as natural marble. Or it is to provide a top surface of the artificial marble furniture having the same to the bottom and the edge.

Another object of the present invention is a method of manufacturing artificial marble furniture top plate having a variety of appearance and luxurious texture, such as natural marble to the edge,

Installing a blocking at a predetermined distance from an edge of the panel to form a space having a desired coating thickness;

Repeating the treatment and curing of the mixture of unsaturated polyester resin and pearl and wax several times in the space next to the edge of the panel until the panel height is reached;

Treating and curing a mixture of unsaturated polyester resin and pearl and wax in the space of the upper surface of the panel;

It is to provide a method of manufacturing artificial marble furniture tops consisting of removing the blocking and finishing.

In order to achieve the object of the present invention, various appearances and luxurious textures, such as natural marble, which consist of panels with a marble pattern / pattern layer of unsaturated polyester resin, pearl and wax on the top and / or bottom and edges There is provided an artificial marble furniture top that has the same top and / or bottom and up edge.

In the present invention, the panel generally includes panels such as MDF, boards, acrylic, low-quality marble, and backlight, which are used as building materials. There is no limitation on the size or thickness of the panel, but it is appropriately used considering the ease of manufacture.

Unsaturated polyester resin is used in building materials, a conventional two-component or three-component unsaturated polyester resin can be used, which can form a coating film of a certain thickness upon curing, non-wax type unsaturated polyester resin is preferred. . Unsaturated polyester resins may also be used to improve physical properties such as hardness, dimensional stability, shrinkage and / or gloss.

Pearl is usually a kind of pigment added to create a beautiful color in furniture paints, there are pearl pearl, golden pearl, copper pearl, silver pearl and the like depending on the color generated. In the present invention, one or more types of pearls are used, and marble surfaces of various colors may be created depending on the type of pearls used and the pigment mixing ratio.

In the present invention, wax is a concept that includes all types of oils used for gloss in a product. Thus, waxes include, but are not limited to, furniture, automotive, and industrial, waxes, varnishes, oil compounds. Oils, fats and the like having properties equivalent to waxes used for gloss of furniture may also be substituted and used. Preferably, water-based solvents and silicone oil-based waxes can be used.

In general, wax has no compatibility with unsaturated polyester resins, and therefore, prior wax treatment has been contraindicated when unsaturated polyester resin paints are used in building materials. However, according to the present invention, when a drop application is applied to an unsaturated polyester resin (drip application), the reaction with the unsaturated polyester resin occurs around the wax drop, and various and luxurious appearances like unexpected natural marble (shape / pattern / Color) artificial marble was formed.

In the present invention, 1000 parts by weight of unsaturated polyester resin may be included in 0.03 to 700 parts by weight of pearl and 0.05 to 50 parts by weight of wax, and the pattern, color and pattern of marble may be diversified according to the mixing ratio of pearl and wax. When the pearl and wax are added below 0.03 parts by weight and below 0.05 parts by weight, respectively, the reaction is insufficient and the artificial marble pattern is not properly formed, and when the content is over 700 parts by weight and 50 parts by weight, respectively, the color becomes too turbid or resinous. Separation occurs and beautiful artificial marble patterns are not formed.

In addition, the artificial marble furniture top plate of the present invention may further include other pigments, such as red, yellow, brown, black, green and the like, which are generally used for paints as needed. The amount of the pigment may vary depending on the color concentration of the desired marble, but the general pigment may include up to 30 parts by weight based on 1000 parts by weight of unsaturated polyester resin. If the pigment exceeds 30 parts by weight, too dark marble patterns / colors are formed, and the curing time of the coating film may be delayed.

In order to achieve another object of the present invention, to the edge of the artificial marble furniture top plate having a variety of appearance and luxurious texture, such as natural marble,

i) installing a blocking at a predetermined distance from the edge of the panel to form a space having a desired coating thickness;

Ii) Repeated treatment several times with 1,000 parts by weight of unsaturated polyester resin in 0.03 to 700 parts by weight of pearl and 0.05 to 50 parts by weight of wax in the space next to the edge of the panel (3) until the height of the panel was reached. Doing;

Iii) treating and curing with 0.03 to 700 parts by weight of pearl and 0.05 to 50 parts by weight of wax in 1000 parts by weight of unsaturated polyester resin in the space of the upper surface of the panel;

Iii) to provide a method of manufacturing artificial marble furniture tops, which comprises the steps of removing blocking and finishing.

In the production process according to the invention, the panels, unsaturated polyester resins, pearls and waxes are as defined above.

Blocking installation in step i), as shown in Fig. 1, forming a blocking by means of a wooden chord or the like at a predetermined distance from the edge of the panel so that a space (frame) for forming a coating film on the panel edge is provided. It is. The predetermined spacing should correspond to the desired molding shape, preferably 3-10 mm, most preferably 5-8 mm. In addition, the height of the blocking is installed 1 ~ 10mm, most preferably 3 ~ 5mm higher than the panel height so that a space (frame) in which the coating film can be formed on the upper surface of the panel is provided. Respectively, if the thickness of the coating film is too thin, the thickness of the coating film becomes too thin, so that the pattern appears blurry. If the thickness exceeds 10 mm, cracks may occur in the marble pattern / pattern layer.

In the component treatment of the coating film of steps ii) and iii), basically, the unsaturated polyester resin and pearl are mixed and the wax is applied dropwise. Specifically, (1) after dropwise applying wax to the space of the panel, a mixture of unsaturated polyester resin and pearl is added; (2) add wax to the panel space by mixing wax with a mixture of unsaturated polyester resin and pearl; ③ first, a mixture of unsaturated polyester resin and pearl is added to the panel space, and then wax is applied dropwise; Or (4) after applying some wax to the space of the panel, adding a mixture of unsaturated polyester resin and pearl, and then applying the remaining wax again.

The appearance of artificial marble of different patterns and patterns can be formed according to the process of ① ~ ④. In particular, when the wax is applied in large drops, the pattern becomes large, and when the wax is applied in small drops, the pattern appears fine.

In the present invention, in particular, the component treatment of the coating film in step ii) is treated and cured several times (divided) until the height of the panel is reached, according to any one of the treatment procedures 1) to 4). Only if this is done repeatedly, an artificial marble furniture top plate having an edge of the same pattern and pattern as the pattern and pattern of the artificial marble formed on the upper surface of the panel can be obtained. At this time, it is preferable to add the diluted polyester resin to the mixture of unsaturated polyester resin and pearl (including pigment when pigment is added) in an amount of 50 to 150% by weight based on the total amount of the mixture. The number of component treatments is typically such that the coating layer generated once is 3 to 8 mm so that the panel can vary depending on the thickness. In addition, the coating film produced in each time can be hardened by leaving room temperature for 30 minutes-1 hour.

In step iii), on the upper surface of the panel where the film formation is completed in the space of the edge in step ii), the components of the coating film are treated up to the blocking height in accordance with any one of the processes of ① to ④, and at 1 to room temperature Leave on for 24 hours to allow complete curing.

In steps ii) and iii), if desired, pigments may additionally be included in the mixture of unsaturated polyester resins and pearls depending on the color. As the pigment, a pigment as defined above may be used. When additional pigments are included, the appearance of more diverse colors of artificial marble can be formed.

In step iii) the finish may be added with a gloss finish by polishing the edges and surfaces of the resulting artificial marble furniture top plate or by coating with an unsaturated polyester resin. Polishing is usually paper processing. In the case of the coating, it is coated with a conventional film coating paper or coated with artificial marble cotton and a release agent, as described in the applicant's patent application No. 2005-2011, which is incorporated by reference in the present disclosure. After the unsaturated polyester resin is injected between the glass plates, and the glass plates are brought into close contact with each other, the glass plate is separated after the resin is cured, thereby forming a high gloss coating. In addition, the finishing of the edge of the top surface of the artificial marble furniture may be first molded according to the shape of the edge (cut according to the shape) and then polished.

If necessary, prior to step i), the treatment of wiping off the top and edges of the panel with a thinner (with cloth) provides better adhesion between the unsaturated polyester resin and the panel. Exciting usually uses polycinna for furniture.

In addition, if necessary, after the block is installed on the lower surface of the panel, a coating film is formed in the same manner as in the above step iii) so that all surfaces of the panel have various appearance and luxurious textures / pattern colors like natural marble. It is also possible to manufacture floors of artificial marble furniture tops.
