Abstract

The invention provides a polyurethane barium titanate composite wave-absorbing material, wherein it is obtained by polymerization reaction of the following components by mass: 100 parts of polyether polyol, 20-70 parts of toluene diisocyanate, 0.01-70 parts of nano carbon sol 0.5 parts, 10-20 parts of deionized water, 5-30 parts of dimethyl methyl phosphate, 2-10 parts of carboxyl multi-walled carbon nanotubes, 10-20 parts of barium titanate, 1-3 parts of nano zinc oxide, nano 0.5-2 parts of tungsten oxide, 1-10 parts of zinc borate, 0.02-0.4 parts of stannous octoate, 0.03-0.6 parts of triethylenediamine, 0.2-3 parts of silicone surfactant, 1-10 parts of sodium bicarbonate. The above-mentioned polyurethane barium titanate composite wave-absorbing material provided by the present invention has the characteristics of low smoke, low toxicity, flame retardant, wide absorption frequency distribution of absorbing waves, and the like. The present invention also provides a preparation method of the polyurethane barium titanate composite wave-absorbing 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 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 tha...
