The invention discloses a kind of phosphatization ester intumescent nylon materials, diatomite is passed through phosphorating treatment by the present invention, then it is blended with pentaerythrite, esterification is carried out at high temperature, obtain phosphide solution, the phosphide solution is not only by bulking filler, diatomite fully organises, improve its compatibility in nylon matrix, reduce reunion, improve the stability_intensity of finished-product material, phosphate can be by catalytic dehydration at carbon in burning simultaneously, material below carbon-coating is played heat-insulated, oxygen-impermeable effect, so that the surface of polymer forms firm protection type layer of charcoal, with good flame retardant property. |
