Abstract

The invention provides a flame-retardation and wave-absorption polyurethane material. The flame-retardation and wave-absorption polyurethane material is obtained through a polymerization reaction of the following components, by mass, 100 parts of polyether polyol, 20-70 parts of toluene diisocyanate, 0.01-0.5 part of nano-carbon sol, 10-20 parts of deionized water, 5-30 parts of dimethyl methylphosphate, 2-8 parts of graphene oxide, 10-30 parts of ferroferric oxide, 1-10 parts of zinc borate, 0.02-0.4 part of stannous octoate, 0.03-0.6 part of triethylenediamine, 0.2-3 parts of an organosilicone surfactant and 1-10 parts of sodium bicarbonate. The flame-retardation and wave-absorption 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 flame-retardation and wave-absorption polyurethane material.

Description

technical field [0001] The invention belongs to the technical field of functional materials, and in particular relates to a polyurethane flame-retardant 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 that can resi...
