| titleOfInvention | Nitrogen phosphorus intumescent flame retardant and preparation method used in waterborne polyurethane coating |
| abstract | The invention relates to a method for preparing nitrogen-phosphorus intumescent flame retardant and applying it to the preparation of water-based polyurethane coatings. Dimethyl phosphite, basic catalyst sodium methoxide and acrylamide are mixed and reacted to obtain an intermediate, and carbon-forming agents and substances are added. A. During the stirring process, the pH of the solution is stabilized at 6.5-7.0, then substance B and substance C are added, and the stirring reaction is continued, and the nitrogen-phosphorus intumescent flame retardant is concentrated to obtain a water-based polyurethane coating. The flame retardant prepared by the invention quickly suffocates the flame, and improves the flame retardancy of the nitrogen-phosphorus intumescent flame retardant from the viewpoints of releasing smoke, controlling the burning time of the flame and the compactness of the carbon layer. In addition, the present invention grafts the nitrogen-phosphorus intumescent flame retardant onto the polyurethane, which further improves the flame retardancy of the polyurethane. |
