Blanket capable of shielding electromagnetic wave

Abstract

The invention discloses a blanket capable of shielding an electromagnetic wave, which is characterized by comprising a surface layer 1, a shielding layer 2 and bottom cloth 3, wherein the shielding layer 2 comprises an aluminum foil layer 4 on the upper part and a copper net layer 5 on the lower part; and the aluminum foil layer 4 and the copper net layer 5 are bonded and fixedly connected. The blanket is mainly used for an electrothermal blanket, has the function of shielding the electromagnetic wave produced by the electrothermal blanket and increasing heating uniformity and permanence of the electrothermal blanket, and also has the characteristics of electricity saving, temperature preservation, no electromagnetic wave radiation, safety, reliability and the like; and the blanket is a necessary product for creating a green household environment. The process has simple preparation and low cost, and is suitable for large-scale production.

Description

technical field [0001] The invention belongs to the technical field of daily necessities, and in particular relates to a blanket capable of shielding electromagnetic waves, which is mainly used in the electromagnetic wave shielding aspect of electric heating blankets. technical background [0002] Since the advent of the electronics industry, it has not only revolutionized science and technology and industrial production, but also brought convenience and comfort to people's lives. However, the electromagnetic waves radiated by various electronic products and equipment fill the living space. Radio broadcasting, television, mobile communication, radio remote control, navigation, high-voltage transmission and distribution lines, etc. all radiate powerful electromagnetic wave energy to the air and the ground. Induction heating equipment such as high-frequency quenching, welding, smelting, cutting, plastic heat sealing, wood drying, electromagnetic physiotherapy, microwave treatm...

AI Technical Summary

Problems solved by technology

At present, electric blankets on the market do not have electromagnetic wave shielding devices. If such electric blankets are used for a long time, electromagnetic radiation will accumulate to a certain extent, which will inevitably cause harm to the human body and cause diseases that should not occur. At present, there are many reports on this aspect. Unnecessary losses to the family
