| titleOfInvention | Flame-retardant polyurethane foam with electromagnetic shielding function and preparation method thereof |
| abstract | The invention discloses flame-retardant polyurethane foam with an electromagnetic shielding function and a preparation method thereof, wherein the flame-retardant polyurethane foam comprises the following steps: step 1: soaking polyurethane foam in a mixed solution A, wherein the mixed solution A is obtained by mixing a phosphoric acid-containing solution and an aniline solution, and the weight ratio of substances containing phosphoric acid and aniline in the mixed solution A is 1: 10-1.5: 1; step 2: adding ammonium persulfate into the mixed solution A in the step 1 for in-situ polymerization, and fully reacting to obtain polyurethane foam coated with the polyaniline doped with phosphoric acid; wherein the mass ratio of ammonium persulfate to aniline is 1: 1-1.5: 1; and step 3: dip-coating the polyurethane foam coated with the phosphoric acid-doped polyaniline in a conductive solution for N times, and drying to obtain the flame-retardant polyurethane foam with the electromagnetic shielding function; the polyurethane foam obtained by the invention has good electromagnetic shielding effect and good flame retardant property, and can pass a vertical combustion test, and the oxygen index can reach 34.2%; the preparation method is simple and environment-friendly. |
