Epoxy resin flame retardance curing agent containing phosphorus and nitrogen and preparation method of epoxy resin flame retardance curing agent

摘要: The invention discloses an epoxy resin flame retardance curing agent containing phosphorus and nitrogen a preparation method of the agent, relates to chemical thereof. Preparation raw materials comprise oxychloride, 1-oxy-phospha-4-hydroxymethyl-2,6,7-trioxabicyclo[2.2.2]octane, m-xylylenediamine. comprises following two steps: firstly, ensuring that oxychloride (POCl3) 1-oxy-phospha-4-hydroxymethyl-2,6,7-trioxabicyclo[2.2.2]octane (PEPA)react with each other in certain condition, so as generate intermediate; secondly, intermediate obtained first step m-xylylenediamine are stirred react for time leading inert gas, carrying out filtering, washing drying obtain white solid. has good compatibility resin, can be cured into whole body is small influence on mechanical property material, not only serve but also effectively improve retardation resin.
