Problems solved by technology

However, these materials only have a shielding effect on the electric wave component of electromagnetic waves, but have no obvious effect on magnetic waves
In addition, when there are local defects in the shielding material caused by collisions between materials or improper use of tools during construction, the shielding effect will be significantly reduced.

Embodiment Construction

[0018] The specific implementation manners of the present invention will be described below in conjunction with the accompanying drawings.

[0019] figure 1 Schematic diagram of the structure of the building interior material for electromagnetic wave shielding made of copper-iron alloy. Such as figure 1 As shown, the building interior material for electromagnetic wave shielding includes a copper-iron alloy foil 1 , a flame-retardant reinforcing material layer 2 , and a copper-iron alloy mesh 3 . The copper-iron alloy mesh 3 is located on the central layer, and the two sides are bonded and clamped by the flame-retardant reinforcing material layer 2, and then the copper-iron alloy foil 1 is glued on both sides of the flame-retardant reinforcing material layer 2. Among them, two layers of copper-iron alloy foil 1 and copper-iron alloy mesh 3 play a shielding role. The copper-iron alloy foil 1 and the copper-iron alloy mesh 3 contain a copper matrix and tiny crystal grains exis...

Abstract

The invention provides a building interior material for electromagnetic wave shielding. The building interior material is characterized by comprising a copper-iron alloy net, fire-resistance reinforcing material layers and copper-iron alloy foils, wherein the copper-iron alloy net is positioned at the central layer; there are two fire-resistance reinforcing material layers which are respectively adhered to two sides of the copper-iron alloy net; and there are two layers of copper-iron alloy foils which are respectively adhered to two sides of the fire-resistance reinforcing material layers. According to the invention, the building interior material for electromagnetic wave shielding has a building electromagnetic wave shielding effect. The material not only has a shielding effect on electric wave but also has an obvious effect of shielding magnetic wave. Thus, the high-performance electromagnetic wave shielding effect can be enhanced. In addition, the material also has a dual effect of preventing obvious drop in the electromagnetic wave shielding capability due to defects caused by carelessness during construction.

Description

technical field [0001] The invention relates to a building interior material for electromagnetic wave shielding, and also relates to a preparation method for the copper-iron alloy used in the building interior material, which belongs to the field of building materials. Background technique [0002] In the past, in order to make buildings have the effect of shielding electromagnetic waves, conductive metals such as copper and aluminum, and shielding materials using thin plates or foils made of carbon materials are usually used. However, these materials only have a shielding effect on the electric wave component of electromagnetic waves, but have no significant effect on magnetic waves. In addition, when there are local defects in the shielding material caused by collisions between materials or improper use of tools during construction, the shielding effect will be significantly reduced. Contents of the invention [0003] The object of the present invention is to provide a ...
