3), nickel oxide (NiO), at least a in zinc oxide (ZnO) and the cupric oxide (CuO), dispersant and lubricant as main composition.The PVC compound comprises PVC, dioctyl phosphate, stabilizing agent, blowing agent, titanium dioxide and filler such as calcium carbonate.
Yet because conventional electromagnetic wave shielding wallpaper is difficult to make, therefore expectability is not boosted productivity.In addition, because metal is used as electromagnetic shielding material, and make manufacturing cost quite high.
For addressing the above problem, the object of the present invention is to provide the wallpaper that is used for shielding electromagnetic wave, by coating one coating composition, described wallpaper can shield outside electromagnetic wave effectively, and the effect of antistatic is arranged; Described coating composition comprises by from by having the additive of choosing a kind of material at least and mixing by predetermined mixing ratio the group that electromagnetic conducting polymer, conductive carbon and graphite forms in essence.
Second purpose of the present invention be, by utilizing the electromagnetic wave shielding wallpaper to shield external electromagnetic waves effectively, and the protection human body exempts from the infringement due to the electromagnetic wave harm.
The 3rd purpose of the present invention is to simplify the manufacturing technique of electromagnetic wave shielding wallpaper, so that easily make described wallpaper, and reduces its manufacturing cost.
Except that aforementioned purpose, the invention still further relates to:, and prevent because the fault of the caused electronic equipment of Electromagnetic Interference by the inwall that utilizes electromagnetic wave shielding wallpaper decoration room.
For achieving the above object, provide a kind of wallpaper of shielding electromagnetic wave, described wallpaper carries out drying to formed coating then and makes by a coating composition being coated at least one surface of body paper; Described coating composition comprises: from choosing a kind of material at least by containing the group that about 1% conducting polymer to about 100% weight solid, conductive carbon and graphite forms, the total amount of material of choosing from this group is the predetermined 1-69% by composition total weight; The matrix polymer of 30 to 98% weight, this matrix polymer contain about 1% matrix polymer to about 50% weight solid, the solvent of 0-59% weight and the additive of 1-40% weight.
In the present invention, conducting polymer materials comprises: polyaniline, polypyrrole, polythiophene and their derivative; Described material can independently use or two or more mix use.
Preferably, matrix polymer is at least a following material that is selected from: acrylic copolymer, acrylic emulsion resin, vinyl emulsion resin, acrylic resin, alkyd resins and mylar.
In addition, body paper also can be at least a following body paper that is selected from: the body paper that substrate is used, the wallpaper composite sheet of body paper, bondedfibre fabric and bondedfibre fabric and body paper.
Bondedfibre fabric is preferably based on the synthetic fiber bondedfibre fabric of artificial fibre, polyester, polypropylene, polyvinyl chloride and polyethylene terephthalate.
By being described in detail with reference to the attached drawings the preferred embodiment of the invention, can make above-mentioned purpose of the present invention and advantage will become more obvious.
