Problems solved by technology

However, with the further development of ray devices and nuclear technology applications in recent years, traditional and single shielding materials can no longer meet the protection requirements of mobile reactors and portable radiation sources.
At the same time, the existing films have the problems of poor waterproof and air permeability. For this reason, we propose a waterproof and breathable film material for preventing electromagnetic radiation and its preparation method and application.

Abstract

The invention relates to the technical field of film materials, specifically a waterproof and breathable film material for preventing electromagnetic radiation. , Deionized water, epoxy resin, acetone, conductive carbon powder, dicyandiamide, plasticizer, finishing agent. The anti-electromagnetic radiation waterproof and breathable film material provided by the invention can be used as the housing of photoelectric components, and as a shielding layer, it can well reduce the influence of electromagnetic radiation on photoelectric equipment and prolong the service life of the equipment. At the same time, it has good waterproof and breathable properties. Performance, keeping the inside of the optoelectronic device in the shielding layer dry, improving work efficiency, has outstanding substantive features and significant progress.

Description

technical field [0001] The invention relates to the technical field of film materials, in particular to a waterproof and breathable film material for preventing electromagnetic radiation and its preparation method and application. Background technique [0002] With the continuous development of electronic technology, a large number of electrical, electronic, and electrical products have come out one after another. The alternating electric field excites a magnetic field around it, and the alternating magnetic field can excite an electric field around it. The electric field and magnetic field are alternately generated and propagated in the air, which we call electromagnetic waves. Because it is invisible, intangible, and short-term contact will not cause discomfort. Once it accumulates into a disease, it is difficult to treat, so the scientific community calls it an "invisible killer". the fourth largest source of pollution. With the continuous development of national defens...
