Abstract

The invention discloses a harmonic and stray electromagnetic radiation restraining material and a preparation method thereof. The harmonic and stray electromagnetic radiation restraining material is prepared from the following components in parts by weight: a radar absorbent, liquid rubber, a sulfurizing agent, a mildew preventive, an anti-aging agent and a diluent. The preparation method comprises the following steps: heating the liquid rubber, the sulfurizing agent, the mildew preventive, the anti-aging agent and the diluent, and uniformly mixing according to a formula amount; adding the radar absorbent; fully mixing; grinding; performing curtain coating and drying to obtain a thin green body; preforming vulcanization to obtain the restraining material disclosed by the invention. The restraining material has the characteristics of high harmonic and stray electromagnetic radiation restraining capability and superior mechanical property, and the problem of interference of harmonic andstray electromagnetic radiation generated by large-power frequency equipment on peripheral precision electronic equipment can be solved effectively.

Description

technical field [0001] The invention belongs to the field of radar absorbing materials, in particular to a harmonic and stray electromagnetic radiation suppressing material and a preparation method thereof. Background technique [0002] Electromagnetic radiation refers to the process in which the energy of the electromagnetic field propagates to the surrounding space in the form of electromagnetic waves, including ionizing radiation and non-ionizing radiation. There is an electric field around any charged object, and the periodically changing electric field will generate a periodically changing magnetic field, forming electromagnetic waves, thereby generating electromagnetic radiation, and excessive electromagnetic radiation will cause electromagnetic pollution. [0003] On the one hand, electronic equipment has obvious sensitivity and vulnerability to electromagnetic radiation interference. The operation of high-power equipment makes the equipment around it subject to stron...
