Abstract

The invention provides a composite wave-absorbing porous polyurethane material. The composite wave-absorbing porous polyurethane material is obtained through a polymerization reaction of the followingcomponents, by mass, 100 parts of polyether polyol, 30-60 parts of toluene diisocyanate, 0.05-0.4 part of nano-carbon sol, 0.2-0.5 part of nanometer white carbon black, 10-20 parts of deionized water, 5-20 parts of dimethyl methylphosphate, 2-8 parts of graphene oxide, 10-20 parts of ferrite, 2-10 parts of zirconium oxide, 2-8 parts of zinc borate, 0.02-0.4 part of stannous octoate, 0.03-0.6 partof triethylenediamine, 0.2-3 parts of an organosilicone surfactant and 2-8 parts of sodium bicarbonate. The composite wave-absorbing porous polyurethane material has the characteristics of low smoke,low toxicity, flame retardancy, and wide absorption frequency distribution of absorbed waves. The invention also provides a preparation method of the composite wave-absorbing porous polyurethane material.

Description

technical field [0001] The invention belongs to the technical field of functional materials, and in particular relates to a polyurethane composite wave-absorbing porous material and a preparation method thereof. Background technique [0002] Absorbing materials refer to materials that can absorb most of the electromagnetic waves projected on its surface and convert them into other forms of energy with almost no reflection. With the development of modern science and technology, the impact of electromagnetic radiation on the environment is increasing. At the airport, flights are delayed due to electromagnetic wave interference; in hospitals, mobile phones often interfere with the normal work of various electronic medical instruments. In addition, electromagnetic radiation causes direct and indirect damage to the human body through thermal effects, non-thermal effects, and cumulative effects. Therefore, controlling electromagnetic pollution and finding a material that can res...
