Problems solved by technology

Domestic electromagnetic wave shielding materials are mainly copper wire mesh, plastic, carbon fiber, metal materials, etc. Military shielding rooms need to be made of steel plates with a thickness of about 3 cm. The shielding performance of these electromagnetic wave shielding materials is mainly reflection, less absorption, and performance Poor, causing defects such as secondary electromagnetic pollution,

Abstract

An electromagnetic wave absorbing nano-class plastic product is prepared from the plastic mother particles including ABS, POM, PE, PA, PC, PMMA, PS and PVA and the nano material including beta-silicon carbide nanoparticles, Ni nanoparticles and polyphenylamine through mixing said plastic mother particles, ultrasonic-mixing and granulating said nano material, mixing them together, drying, and injection (or blow) moulding. Its advantages are wide bandwidth, high absorptivity and no secondary pollution.

Description

Technical field [0001] The invention discloses a plastic material, in particular to a preparation method of a nano-wave absorbing composite plastic material and a product thereof. Background technique [0002] The 21st century is the information age. It is an era in which new materials and advanced manufacturing technologies are rapidly developed and widely used. It is also an era in which people pursue efficient, clean and safe use of new energy. The development of science and technology and the continuous emergence of new technologies will inevitably lead to new industries. revolution. Developing countries have successively invested a lot of manpower and financial resources in materials science. Especially in the fields of aerospace, aviation, transportation, construction, etc., they have put forward higher requirements for materials used. Among them, the demand for high-tech materials is increasing. One of the three major materials has been widely used. [0003] Stealth techno...
