Description

Method for manufacturing sliding plate surface pattern and sliding plate

The present invention relates to a method for producing a surface pattern of a sliding plate which can be used for sports such as skiing, water skiing, surfing, grass skiing and sand sliding, and a sliding plate produced by the method. Background technique

The basic structure of the existing sliding plate is formed by laminating a panel, a core plate and a bottom plate. In order to make the sliding plate light in weight and good in strength, the core plate is generally made of a lighter material having a lower density; to reduce the sliding friction, the outer surface of the bottom plate of the sliding plate is made of a low friction coefficient and impact resistant polyethylene. Solid sheet manufacturing; In order to increase the aesthetics of the sliding plate, the outer surface of the panel of the sliding plate may be covered with a film printed with various colors or embossed patterns. The panel, core and bottom plates are bonded together by heating, rolling and cooling. A sliding plate structure and a method of manufacturing the same are disclosed in U.S. Patent No. 5,211,,,,, the disclosure of which is incorporated herein by reference. The method is the first method of printing the pattern on the inner side of the film (the side bonded to the panel), and heating the bonding surface by using a temperature of 180-220 degrees Celsius, first rolling the patterned film with a roller. The aforementioned panel is fabricated on the surface of a high density dielectric layer (e.g., a high density foamed panel) which is then overlaid on the core panel. The sliding plate manufactured by this processing method has the following disadvantages:

1. It must be rolled with a hot roller with embossed pits to make the pattern film adhere to the high-density dielectric layer to form a pattern of concave and convex effect. If the glossy film is pressed to bond the patterned film and the high-density dielectric layer, the patterned film is not firmly bonded, and is easy to fall off in a large area, thereby shortening the service life of the sliding plate;

2. The surface of the attached pattern film is uneven and not aesthetically pleasing;

3. When bonding, the heating temperature is as high as 220 degrees Celsius; in order to make the surface layer and the core board firmly adhered, a high-density dielectric layer must be added between the surface layer and the core board, so that the process is more and the production cost is higher. . Summary of the invention

One of the objects of the present invention is to solve the technical problem that the color of the surface of the conventional sliding plate is not bright enough and the pattern has poor gradation. A method for obtaining a vivid color pattern of the sliding plate surface and vivid vividness of the pattern is proposed.

Another object of the present invention is to solve the problem that the surface of the existing sliding plate has irregularities and irregularities, and each layer The problem of unreliable bonding and short service life is to provide a sliding plate in which the layers of the sliding plate are firmly and reliably combined, the surface pattern is colorful, and the pattern is vivid.

In order to solve the first technical problem, the present invention provides a method for fabricating a surface pattern of a sliding plate, the steps of which are as follows:

a, the production of the base layer: according to the need to select the foam material, to make a foamed base layer;

b, printing of the pattern: according to the selected pattern, at least one of the surface of the base layer is sequentially subjected to four sets of color dot screen printing and thermal drying to obtain a base layer with a patterned layer;

c. Production of a cover pattern layer: a hot-melt adhesive film, a transparent plastic film in a hot-melt state is sprayed on the surface of the patterned base layer, and the adhesive film is attached to the substrate The surface of the patterned layer is then fed into the roll of the roll by a layer of a transparent plastic film and an adhesive film, which are cooled by roll bonding to form a cover sheet.

In a preferred embodiment of the manufacturing method of the present invention, a plastic over-layer film in a hot-melt state may be sprayed on a surface of the base layer, and then the thin touch surface is subjected to an electric spark treatment to cause pits on the surface of the surface. Then, the printing of the post-pattern and the production of the cover pattern layer are performed on the surface.

In an embodiment of the manufacturing method of the present invention, the surface of the base layer to be printed may be subjected to an electric spark treatment, a pit is formed on the surface, and a plastic over-layer film in a hot-melt state is sprayed on the surface. This surface of the base layer is subjected to an electric spark treatment on the thin surface to produce pits on the surface, and then the surface is subjected to post-pattern printing and cover pattern layer fabrication.

In still another embodiment of the manufacturing method of the present invention, after the base layer is fabricated, the surface of the base layer to be printed may be subjected to electrical discharge treatment, a pit is formed on the surface, and then the surface is printed and printed. Cover the production of the pattern layer.

Wherein, the screen printing and heat drying process of sequentially performing color registration in the pattern printing may be four to eight times.

The plastic film and the plastic overlayer film are made of any material of polyethylene, polypropylene, ethylene terephthalate polyester, polyolefin and acrylonitrile-butadiene-styrene; The material is made of any one of ethylene vinyl acetate, crosslinked polyethylene, non-crosslinked polyethylene, crosslinked polypropylene, and non-crosslinked polypropylene; and the adhesive film is a hot melt adhesive resin film.

The base layer may be a continuously wound sheet or a sheet of sheet.

In order to solve the second technical problem, the solution of the present invention is to construct a sliding plate including a core plate, a panel and a bottom plate respectively covering the core plate and the lower side. The panel comprises: a surface layer bonded to a surface of the core board; a pattern layer of a dot printed on the outer surface of the surface layer, sequentially covering the pattern An adhesive film on the layer and a transparent plastic film; the bottom plate comprises: a base layer which is combined with the other coat of the core maple, a pattern layer which is screen printed on the outer surface of the base layer, and sequentially covers the pattern layer The film is then applied to a transparent plastic solid board.

In another preferred embodiment of the sliding plate of the present invention, a plastic over-layer film having a pit on the surface is respectively disposed between the surface base layer or the base layer in the panel and the bottom plate and the pattern layer.

The method for printing a pattern on the surface of the sliding plate is different from the traditional manufacturing method, and is characterized in that the pattern is directly printed on the surface of the excessive layer by using the dot-spot color screen printing process, thereby obtaining a vivid and vivid pattern, which is printed. The pattern effect can be close to the effect of offset printing; the transparent plastic film is adhered to the surface of the surface layer or the base layer printed with the ink pattern layer through a special adhesive film, and has excellent water repellency, and the surface can also be obtained as The same glossy effect of the photo, without the need to use a pair of heated rollers to bond the outer film to the base layer or the base layer, so that the layers are firmly bonded and the outer surface of the base or base layer is flatter. The silk screen effect is more beautiful. If a surface of the base layer or the base layer is first coated with a layer of plastic over-layer film with a pit, and then printed and pasted with a transparent plastic film, the layers are more firmly adhered to each other and can be more effective. The ink pattern is closed to meet the requirements of hygiene and safety. DRAWINGS
