Abstract

The invention provides a polyurethane-barium titanate composite wave-absorbing porous material. The material is prepared from 100 parts by mass of polyether polyol, 30 to 60 parts by mass of toluene diisocyanate, 0.05 to 0.4 parts by mass of nanometer carbon sol, 0.2 to 0.5 parts by mass of nanometer white carbon black, 10 to 20 parts by mass of deionized water, 5 to 25 parts by mass of dimethyl methylphosphate, 2 to 8 parts by mass of graphene oxide, 10 to 20 parts by mass of barium titanate, 1 to 3 parts by mass of nano-zinc oxide, 0.5 to 2 parts by mass of nano-tungsten oxide, 2 to 8 partsby mass of zinc borate, 0.02 to 0.4 parts by mass of stannous octoate, 0.03 to 0.6 parts by mass of triethylenediamine, 0.2 to 3 parts by mass of an organosilicone surfactant and 2 to 8 parts by massof sodium bicarbonate through polymerization. The polyurethane-barium titanate composite wave-absorbing porous material has the characteristics of low smoke, low toxicity, flame retardancy and wide absorption frequency of absorbed waves. The invention also provides a preparation method of the polyurethane-barium titanate composite wave-absorbing porous material.

Description

technical field [0001] The invention belongs to the technical field of functional materials, and in particular relates to a polyurethane barium titanate 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 mater...
