Embodiment

[0016] The inorganic fiber mesh cloth can be glass fiber mesh cloth, and the metal coating on the surface of the inorganic fiber mesh cloth can be an alloy of copper, nickel, and zinc. The microporous plastic layer can be fluoroplastic, which is characterized in that the diameter of the micropores is 0.2 μm to 10 μm, and the thickness of the plastic layer is 10 μm to 60 μm. The decorative paper can be titanium white paper with printed patterns.

[0017] In order to solve the above problems, the present invention also provides a preparation method of electromagnetic shielding wallpaper, which is characterized in that it comprises the steps in the following order:

[0018] (1) The surface of each bundle of fibers of the glass fiber mesh cloth is wrapped with an alloy coating of copper, nickel, and zinc to form a mesh cloth 10 wrapped with a metal coating.

[0019] (2) Polyurethane adhesive 20 is coated on the surface of the microporous fluoroplastic 30, and laminated with the g...

Abstract

The invention discloses and provides an electromagnetic shielding composite wallpaper, which is characterized in that the wallpaper is composed of the following layers from the inner to the outer: fiber gridding cloth and metal coated on the surface thereof 10, an inner adhesive layer 20, a micro-porous plastic layer 30, an outer adhesive layer 40, and decoration paper 50, wherein the layers are connected through an adhesive. The invention also provides a manufacturing method of the electromagnetic shielding composite wallpaper. The electromagnetic shielding composite wallpaper provided by the invention has an electromagnetic shielding function, has the characteristics of alkali resistance, weatherability, and good fire resistant performance, does not carry out chemical reactions with alkaline cement plaster, and can be widely applied to fields that needs heat insulation under cold, hot, and damp environment, such as machinery, electronics, construction, aviation, aerospace, automobiles, and naval vessels.

Description

technical field [0001] The invention relates to a composite wallpaper and a preparation method thereof, in particular to an electromagnetic shielding composite wallpaper and a preparation method thereof. Background technique [0002] Wallpaper is used as a decorative material in many fields. However, the composite wallpaper with electromagnetic shielding effect has not been developed and applied. In addition to the decorative effect, the electromagnetic shielding composite wallpaper also has the function of protecting indoor electromagnetic signals from leakage and avoiding outdoor electromagnetic signals. interfere with the function. [0003] The utility model patent with application number 200820200416.8 discloses a kind of wallpaper, which is used for wall decoration, and the wallpaper does not have the function of electromagnetic shielding. [0004] The invention patent with application number 200680016573.7 discloses a shielding film, which can be directly used for ele...
