Bamboo decorative panel and its manufacturing method {Bamboo decorative panel and its manufacturing method}

The present invention relates to a bamboo decorative panel, and more particularly, by making a bamboo panel having a membrane between nodes and nodes by turning round bamboo vertically, it can be used as a decorative panel for wall boards, ceiling materials, flooring materials, tables, etc. It relates to a bamboo decorative panel and a manufacturing method thereof.

The bamboo industry, which had been active until the 70s, began to decline as mass-produced industrial products replaced bamboo products from the early 80s, and bamboo resources have been neglected. In addition, due to the emergence of plastic substitutes and the mass inflow of cheap bamboo products from China or Southeast Asia and rising labor costs, bamboo groves were not properly managed and neglected, and there was no use method on an industrial scale, so the domestic bamboo industry was on the decline. By the bay, bamboo forest farmers could no longer earn income.

Bamboo grows very quickly, has strong vitality and fertility, and, unlike other woods, it has a cylindrical shape with a large space inside. Bamboo with this characteristic is not a bamboo work product such as a basket, a tray, or a colander. It is mainly used as a material for various types of wind instruments, including a flute, a container material such as a seasoning container, a pencil case, a luxury tea container, and a liquor container, or as a material for furniture such as chairs and lighting equipment. On the other hand, out of the total distribution area of Korea's bamboo resources of 24,111ha, the economically valuable Somdae, Wangdae, and Maengjongjuk (孟宗竹) are 22,998ha. It has abundant resources, accounting for 0.36% of the forest area.

The applicant (inventor) has been working for several decades at the National Institute of Forest Science, a national research institute that conducts research on forestry, forestry, and timber industry in Korea, and has developed, distributed and patented many technologies related to wood. Regarding the patent registration No. 1334737, "Bamboo medicine injection device" was patented. In order to expand the field of utilization of abundant bamboo resources, in addition to the existing bamboo products, liquid chemicals such as preservatives and resins are rapidly injected into bamboo to prevent the bamboo from being split. It is a technology for processing so that the blue color of the outer shell is not discolored and preserves the original shape and the color of the outer shell can be maintained for a long time. In addition, patent registration No. 1828777 "Manufacturing method of bamboo charcoal balls using round bamboo balls", which relates to a method of manufacturing charcoal balls by processing bamboo into a round ball shape and then carbonizing it. Adsorption and deodorization of harmful substances It is to take advantage of the effects and various benefits of charcoal that are beneficial to the human body.

In recent years, many unique new materials and products have emerged in various forms in the interior and decoration fields, but products or technologies that utilize the membrane between the nodes and the nodes of bamboo have not appeared until now, but the external aesthetics of bamboo. ), and the emergence of products and technologies made of environmentally friendly materials that utilize the membrane between nodes and nodes as they are are required, and the present invention has come to meet such demands.

The present invention has been conceived in response to the above requirements, and an object of the present invention is to make a rounded bamboo vertically thin and long, and have a film between the nodes and the nodes as it is. The purpose is to provide a bamboo decorative panel that can be used for decoration on environmentally friendly wallboards, ceiling materials, flooring, and tables by arranging them at regular intervals and making them in the form of panels by attaching Korean paper and glass on both sides.

Another object of the present invention is to prevent the occurrence of mold and invasion of decaying bacteria caused by starch contained inside the bamboo, thereby imparting weathering and insect repellent functions to the bamboo panel, thereby improving preservation. It is to provide a method of manufacturing bamboo decorative panels that can be given various colors for aesthetic purposes.

The bamboo decorative panel according to the present invention is manufactured by laying round bamboo in a thickness of 0.5 to 2.0 cm long and thin so as to retain the membrane between the nodes and the nodes, and a longitudinal flat plate with holes formed in the lateral direction (平板) bamboo; A string inserted into a hole formed in the lateral direction of the longitudinal flat bamboos arranged adjacent to each other to connect the longitudinal flat bamboos; A frame manufactured in a square shape using a rod shape, connected by a line to the inside of the square shape, and inserted into a vertical flat bamboo arranged at regular intervals; It characterized in that it comprises a decorative paper attached to both sides of the vertical flat bamboo connected to each other.

Preferably, the decoration paper uses any one of Korean paper, banana paper, pattern paper, acrylic, and glass.

The manufacturing method of the bamboo decorative panel according to the present invention is that round bamboo is made thin and long vertically with a thickness of 0.5 to 2.0 cm, so that the membrane between the nodes and the nodes remains as it is to make a flat bamboo. step; Drying the longitudinal flat bamboo; Processing a hole in the lateral direction of the dried longitudinal flat bamboo; Inserting a string into the hole formed in the lateral direction of the longitudinal flat bamboo to connect the longitudinal flat bamboo; Manufacturing a bamboo panel by inserting the connected longitudinal flat bamboo into the frame; It is characterized in that it is produced through the step of attaching decorative paper to both sides of the bamboo panel.

Preferably, after drying the vertical flat bamboo, it is further subjected to a step of bleaching, heat treatment or preservative treatment to impart weathering and insect repellent functions and various colors.

If round bamboo is cut lengthwise and thinly and long in a thickness of 0.5 to 2.0 cm to make a flat plate, the membrane is still attached between the node and the node of the bamboo, and the bamboo is connected at both ends. Since the membrane is positioned at regular intervals inside the round shape of the bamboo, it is possible to create a flat plate with a variety of shapes that hardly have the same shape for each vertical plate. The bamboo decorative panel according to the present invention is a vertical flat bamboo of such various shapes. It is an eco-friendly natural panel because it is produced in the form of a panel by connecting them with strings or strings or placing them at regular intervals and attaching Korean paper, banana paper, glass, and acrylic to one or both sides. It can be used for decoration on tables, etc. to decorate the interior beautifully. In addition, if you illuminate one side or install it on the ceiling, you can decorate the room elegantly and elegantly with subtle lighting.

In addition, since bamboo is a plant from which edible bamboo shoots are grown, the inside of the bamboo contains a lot of starch compared to ordinary trees, and if it is not removed, the bamboo is eaten by the bamboo beetles, so it is heated with a torch lamp. Bamboo panels are treated to make the skin of the bamboo shiny while removing the material and give color, boil treatment, bleach treatment, smoke treatment, wood vinegar treatment, wood tar treatment, preservative treatment, vacuum treatment, etc. The external aesthetics and preservation of the bamboo are remarkably improved, and the wax component is present along with starch in the skin of the bamboo, that is, the shell part, so when heated, the wax melts and the surface becomes smoother, and the preservation property is remarkably improved.

2 is a photograph of Korean paper to be used for a decorative panel.
3 is a flow chart schematically showing a method of manufacturing a bamboo decorative panel.

The technical feature of the bamboo decorative panel according to the present invention is that the bamboo is formed thin and long with a thickness of 0.5 to 2.0 cm in length so that it retains the membrane between the nodes and the nodes, so that the bamboo is connected to each other or fixed at regular intervals, and is The point is that it can be used as an environmentally friendly decorative panel by attaching glass or the like to make it in the form of a panel.

The bamboo decorative panel according to the present invention is arranged to be inserted into a frame made of a square shape by arranging the round bamboo thinly-lit flat bamboos adjacent to each other and connecting them with a row or arranged at regular intervals. Or it is a decorative panel produced by attaching decorative paper on both sides.

Jongjeol (平板) flat bamboo is made by cutting round bamboo 0.5~2.0cm thick vertically and thinly and long so that it retains the membrane between the nodes. The round bamboo is vertically oriented using a round machine saw. Because it is cut with a frame, the membrane is positioned at regular intervals (meaning between nodes and nodes) inside the round shape of the bamboo, and since the bamboo is round, flat plates with various shapes that hardly have the same shape for each of the vertical flats are made ( 1). Therefore, it is possible to create an environmentally friendly natural panel. At this time, if the thickness of Jongjeol flat bamboo is turned on to less than 0.5cm, the film holding the bamboo at both ends will be cracked and twisted during the drying process. It is possible to turn it on more than 2cm, but it is not economical if it becomes too thick.

In order to make a panel, a hole is formed in the upper and lower portions in the longitudinal direction of the longitudinally (referring to the inward direction from the outer skin of the bamboo), because the longitudinal flat bamboos must be arranged adjacent to each other at regular intervals. It should be installed, and it should be connected by inserting a string into the hole formed in the vertically arranged flat bamboo. It is preferable to use a string with irregularities by twisting the string like a young string. If the string has irregularities, it is possible to suppress the lateral movement of the vertical flat bamboo. In addition, the length and width of the panel can be varied only by adjusting the length and the number of laterally connected vertical flat bamboos.

The frame is manufactured in a square shape using a rod shape, and a vertical flat bamboo is inserted into the square shape and connected with a row at regular intervals, and the size of the panel is determined according to the size of the frame, and the thickness of the frame is It is preferable to make it thicker than the thickness of vertical flat bamboo. Here, the frame does not necessarily have a square shape, and can be manufactured in various shapes without any technical difficulties depending on the location or need to be used.

In addition, without using a string when connecting the vertical flat bamboo, the vertical flat bamboo is placed at regular intervals and inserted into the frame to determine the position, and a packing material made of styrofoam, rubber, plastic, wood, etc. is used between the gaps. You can also fix the flat bamboo so that it does not move from side to side.

The decorative paper is attached to one or both sides of the vertical flat bamboo in order to add the beauty of the panel, and it is preferable to use a transparent or translucent one such as Korean paper, banana paper, pattern paper, acrylic, and glass. In particular, if you attach materials such as Korean paper, banana paper, and acrylic paper that have a unique shape and install lighting below or above, you can create a cozy and elegant indoor atmosphere.

The method of manufacturing a bamboo panel according to the present invention is a step of producing a vertically thin and long round bamboo with a thickness of 0.5 to 2.0 cm so as to retain the membrane between the nodes and the nodes as it is (S1), drying the longitudinal flat bamboo (S2), processing a hole in the lateral direction of the dried longitudinal flat bamboo (S3), and inserting a string into the hole formed in the lateral direction of the longitudinal flat bamboo It is produced through a step (S4) of connecting longitudinal flat bamboos to each other, a step (S5) of manufacturing a bamboo panel by inserting the connected longitudinally flat bamboo into a frame (S5), and a step (S6) of attaching decorative paper to both sides of the bamboo panel. . In addition, after drying the jongjeol flat bamboo, boiling treatment, bleaching treatment, heat treatment, smoking treatment, wood vinegar treatment, wood tar treatment, preservative treatment or vacuum treatment may be further performed.

In the step of drying the bamboo (S2), since the moisture content of the outer and inner surface of the bamboo is different, the film will crack and distort when the bamboo is dried at a sunny or high temperature. Make sure to dry enough.

The bleaching treatment is a treatment in which the bamboo is heated with hot water using bleach such as caustic soda, hydrogen peroxide, and baking soda to dissolve the starch. When bleaching is performed, the green color of the bamboo shell disappears and turns yellow by bleaching. As you do, the outer skin becomes shiny.

Bamboo has a straight line of cellular tissue, and the surface layer is composed of a layer of wax that cannot penetrate liquid, and the inside of the bamboo contains starch, so if it is not removed, powdery mildew or swelling bacteria will eat the bamboo. For this reason, it is desirable to heat treatment to remove the starch while treating the bamboo bark to make it shiny. When heating treatment, use a torch lamp, etc., to bring the flame to the outer shell of the flat-plate bamboo, and the essence will come out to the outer skin of the bamboo and the outer skin will be shiny.If you do 1 or 2 times, the color of the outer skin turns slightly brown. If performed several times, it is carbonized and turns black.

When manufacturing panels on a large scale, it may be difficult to work individually with a torch lamp.Therefore, the smoke from the production of charcoal is not immediately discharged to the outside, and the dried flat bamboo is placed in a certain container (container box, etc.). If the smoke is kept circulating continuously, the wood vinegar and wood tar contained in the smoke permeate evenly across the entire flat-panel bamboo, and the color of the outer shell changes to brown (when smoked for a short period) or black (when smoked for a long period).燻煙) treatment can also be performed. When the smoke treatment is performed in this way, ultrafine dust and wood tar contained in the smoke harmful to the environment are reduced.If the smoke emitted when the charcoal is produced is immediately discharged, ultrafine dust containing fine wood tar is immediately discharged into the atmosphere.

Preservative treatment is a process of impregnating bamboo using wood preservatives such as boron, boric acid, organic iodine compounds, copper, alkyl ammonium compounds, copper, boron, and azole compounds. The preservative treatment gives the bamboo an antiseptic and insect repellent effect. You can do it.

The smoke generated in the process of making charcoal is composed of gaseous wood gas and liquid wood vinegar liquid, and wood vinegar is separated into three layers after a certain period of time.The top layer is a thin film of light oil, the middle layer is water-soluble light brown wood vinegar liquid, and the lower layer is Heavy weight and black useful wood tar are generated. Wood tar treatment makes it possible to impart antiseptic and insect repellent effects to bamboo. In addition, wood vinegar has a sterilizing effect because it is a weakly acidic substance.

Vacuum treatment, like double-layer vacuum glass, is made by inserting vertical flat bamboo into the frame, then attaching the glass to both sides of the vertical flat bamboo panel and then sealing it to prevent air from penetrating the inside of the vertical flat bamboo panel. This is a treatment that improves storage properties.

The above description is an illustrative description of the present invention, and the embodiments published in the specification are not intended to limit the technical idea of the present invention, but to explain the present invention. Various modifications and variations will be possible without departing from the technical idea of Therefore, the scope of protection of the present invention is interpreted by the matters described in the claims, and technical matters within the scope equivalent thereto should be construed as being included in the scope of the present invention.
