| titleOfInvention | Derivative of flame-retardant environment-friendly diphenylmethane diisocyanate and synthetic method thereof |
| abstract | The invention relates to a flame-retardant environment-friendly diphenylmethane diisocyanate derivative and a synthesis method thereof, belonging to the technical field of polyurethane materials. The derivative is obtained by reacting aniline serving as a raw material with formaldehyde to generate a diphenylamine intermediate and then carrying out phosgenation, or is obtained by reacting an aminophenylphosphonic acid derivative serving as a raw material with formaldehyde to generate a diphenylamine intermediate and then carrying out phosgenation. The invention can additionally improve the flame retardant capability on the basis of the existing flame retardant level of polyurethane products, improves the upper limit of foam flame retardant, and can realize the purpose of improving the environmental protection index of polyurethane foam by adding no or little flame retardant in the polyol component. |
