Electromagnetic wave radiation resistant multilayer composite veneer based on field source shielding technology

Abstract

The invention discloses an electromagnetic wave radiation resistant multilayer composite veneer based on a field source shielding technology, relates to the technical field of electromagnetic wave radiation shielding, and aims to solve the problems that existing electromagnetic radiation shielding mainly adopts metal foils for blocking, and when a blocking part is usually provided with a single-layer metal foil, the structural strength is low, the service life is short, the shielding effect needs to be improved, and driving and driven shielding cannot be compatible. A first aluminum foil covering layer, a first kraft paper covering layer, a reinforcing net wire layer, a second aluminum foil covering layer, a second kraft paper covering layer and a third aluminum foil covering layer are arranged in a composite veneer body. The first aluminum foil covering layer and the first kraft paper covering layer are bonded through a first adhesive layer, the second aluminum foil covering layer andthe second kraft paper covering layer are bonded through a second adhesive layer, and the second kraft paper covering layer and the third aluminum foil covering layer are bonded through a third adhesive layer.

Description

technical field [0001] The invention relates to the technical field of electromagnetic wave radiation shielding, in particular to a multilayer composite veneer anti-electromagnetic wave radiation based on field source shielding technology. Background technique [0002] The broad sense of electromagnetic radiation usually refers to the electromagnetic spectrum; the narrow sense of electromagnetic radiation refers to the radiation waves generated by electrical equipment, usually below the infrared, and the mechanism of electromagnetic radiation harming the human body is mainly thermal effect, non-thermal effect and accumulation effect, etc. , so electromagnetic radiation shielding is required in some places with high electromagnetic radiation to avoid affecting the health of workers in the workplace. [0003] Existing electromagnetic radiation shielding mainly uses metal foil to block, when the blocking part is often only a single layer of metal foil, the structural strength i...

Problems solved by technology

[0004] The purpose of the present invention is to provide a kind of anti-electromagnetic wave radiation multi-layer composite veneer based on field source shielding technology, to solve the existing electromagnetic radiation shielding in the above-mentioned background technology Metal foil is mainly used for barrier. When the barrier part is often only a single layer of metal foil, the structural strength is not high, the service life is short, the shielding effect needs to be improved, and the active and passive shielding cannot be compatible.
