| description | The invention relates to the technical field of high polymer materials, and discloses halogen-free flame-retardant epoxy resin and a production method thereof.The halogen-free flame-retardant epoxy resin is prepared from epoxy resin, a curing agent, a diluent and a functional additive through a blending-curing process. Hydroxyl in the structure participates in the curing reaction of epoxy resin, so that the cured epoxy resin with a three-dimensional branched network structure and intertwined molecular chains is formed, and the mechanical properties of the cured epoxy resin can be effectively improved. Besides, silicon, nitrogen and phosphorus resistance elements rich in the functional additive structure can form a dense expanded carbon layer for depositing silicon during combustion of the cured epoxy resin, oxygen and heat can be effectively isolated, and the effect of locking smoke generated by combustion in the material can be achieved, so that the flame retardant property of the epoxy resin can be greatly |
