However, this wallpaper has a problem that the foamed resin layer is formed on the base layer rather than the surface layer, so that the mold is generated after processing or during use due to poor breathability.

In addition, wallpaper (Japanese Patent Laid-Open No. 2005-2308) for laminating a resin sheet formed by foam molding on the base material layer, laminating both layers with an adhesive, or pressing and laminating fused polyethylene between layers is described. Above the decomposition temperature, there remains a problem that roll processing is impossible.

In addition, although a olefinic synthetic resin sheet is used as a surface layer, a wallpaper (Japanese Patent Laid-Open No. 2003-129386) which suppresses shrinkage generated during wallpaper construction is known, but there is a difficulty in processing because gas ejection by a chemical blowing agent occurs.

In addition, although the embossed wallpaper (Korean Patent No. 2002-57870) in which a surface paper, a PE resin film layer, and a printing layer are laminated from the bottom is disclosed, the film layer of only the PE resin has a problem of insufficient air permeability.

The present invention is to solve the problems of the prior art to provide a breathable wallpaper using an olefin material having excellent breathability, easy processing and beautiful appearance and a method of manufacturing the same.

The breathable wallpaper using the olefin material of the present invention is to provide a breathable wallpaper using an olefin material having excellent breathability by forming the surface protective layer of the olefin resin compound containing an inorganic filler and a method of manufacturing the same.

It is preferable to use 1-100 weight part with respect to 100 weight part of resin. If it is less than the above range, the breathability and reinforcement is inferior, and if it exceeds the above range, there may be a problem that the surface properties (tensile strength, tear strength, etc.) fall and the surface is rough.

The size of the filler particles is preferably between 1 micron meter (μm) and 50 micron meter (μm) in diameter. If the diameter of the filler exceeds 50 μm, the surface of the formed olefin resin film layer may be rough or the strength may be weakened. If the diameter of the filler is less than 1 μm, there may be a problem of poor air permeability of the formed olefin resin film layer. have.

The filler exhibits a breathable function because pores are formed together when the filler is included in the composition to form a layer, so that the pores and the inorganic filler become air passages. Humid air can also travel through the air gaps, allowing moisture from the walls to escape and prevent the formation of mold.

The flame retardant is added to block the ignition caused by Volatile Organic Compound (VOC) generated during processing and molding and to give flame retardancy during use, for example, antimony oxide (Sb 2 O 3), aluminum hydroxide (Al ( OH) 3) and at least one selected from the group consisting of magnesium hydroxide (Mg (OH) 2), and the composition ratio is preferably 1 to 10 parts by weight based on 100 parts by weight of the olefin resin. If it is less than the said range, flame retardance will fall, and when it exceeds the said range, there exists a possibility that the processing problem which resin melting temperature falls may arise.
