In the present invention, a main board is formed by combining veneer veneer, an adhesive layer, and a core board using a press, etc., and then going through a seasoning process, and then painting a mixed colored resin to create various colors on the upper surface of the main board, or painting the surface. By manufacturing boards by combining protective layers to improve protection and durability, the texture and color of the wood is maintained while improving physical properties such as scratch resistance, abrasion resistance, heat resistance, cold resistance, acid resistance, water resistance, pressing strength, dimensional change, and flame resistance. It relates to an interior board and its manufacturing method that enable the reduction of manufacturing costs and cost savings in the event of defects, thereby ensuring product quality stability.

In general, natural wood panels and artificial wood veneer sheets are widely used as wall finishing materials and flooring materials that are installed as interior finishing materials on interior walls and floors of houses, etc.

Wood panels are widely used as wall and floor materials due to their excellent decorativeness and durability with natural patterns, but they are expensive and therefore uneconomical. Artificial wood veneer sheets have disadvantages such as low durability and poor appearance, so in recent years, they have had some degree of decorativeness. Attempts are being made to develop wallpaper and flooring using cork, which has excellent elasticity, cushioning, and sound-absorbing properties.

The invention of constructing cork wallpaper using cork, which has functional properties such as cushioning and sound absorption, is known in Publication No. 1995-27098, Publication No. 1998-069811, and Publication No. 20-0244378 of Registered Utility Model. .

These cork wallpapers utilize the functional advantages of cork as a wall finishing material by making use of the advantages of cork, which is made of porous cells and has elasticity and flexibility, and has excellent sound absorption. However, the cork pattern is exposed as it is, so it lacks the aesthetics of natural veneer. Compared to this, it inevitably lacked decorativeness and aesthetics, and had the disadvantage of being weakly durable, such as being easily damaged by external scratches.

In addition, in Patent Publication Nos. 10-1998-25251 and 10-2003-91140, decorative materials are known in which a protective layer is formed on one side of the cork and a color pattern printing layer is formed, but these have lower decorative beauty compared to interior materials made of natural wood veneer. It was not excellent, and the protective layer was also prone to peeling off, so it had many problems, such as short service life due to not properly protecting the cork layer.

On the other hand, it is known in Patent Publication No. 10-2004-79225 that it is made of wall or floor material by taking advantage of the excellent decorative appearance and durability of natural veneer, which is an advantage of natural veneer wood. ) was adhesively bonded to maximize the decorative beauty of natural veneer, but there were problems such as moisture build-up between the non-combustible sheets combined with the natural veneer sheet.

In other words, since the natural wood veneer sheet and the non-combustible sheet of aluminum sheet are adhesively bonded, there is a high risk of moisture being generated between them, and since the non-combustible sheet of aluminum sheet is attached to the wall, moisture easily accumulates between the sheet and the wall. Of course, since it could not be released to the outside and stayed inside the wall, many problems with moisture occurred on the wall where it was installed, making it difficult to put it into practical use.

In particular, in addition to the above-mentioned moisture problem, it had problems such as lack of flexibility, making construction itself completely impossible on the adhesive surface with grooves.

In other words, the interior veneer sheet using the existing natural veneer sheet is focused only on fire prevention purposes by applying a flame retardant to the surface of the natural veneer and adhesively bonding a non-combustible sheet of aluminum, thereby providing buffering properties and moisture control functions required as an interior finishing material. Ease of construction was not properly provided.
