Abstract:
in order to study the flame retardant and smoke suppression effect of boric acid melamine (MB) in intumescent fire retardant coatings, the small room method, tunnel method, large plate method, Cone calorimeter, thermogravimetric analysis (TGA) the effects of different content of MB on the flame retardant and smoke suppression properties of the coatings were studied by Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). The results show that the flame retardant and smoke suppression performance of the fire retardant coating can be improved by adding proper amount of MB. When the mass fraction of MB is 5%, the synergistic flame retardant and smoke suppression effect of the coating is the best, the flame propagation ratio was 11. 9. The expansion ratio of carbon layer is 48. 4; MB can promote the coating in the combustion process to form more P-O-C,B-O-P and C = C and other thermal stability structure to improve the thermal stability of the coating and the amount of carbon, the dense honeycomb skeleton structure was formed to increase the density and expansion degree of the carbon layer, and to achieve the purpose of synergistic flame retardant and smoke suppression.

Abstract:
The invention is a preparation method of superfine boric acid melamine. The specific operation steps of the method are as follows: firstly, boric acid, melamine and deionized water are accurately weighed according to the formula, boric acid and melamine are dissolved in deionized water and stirred evenly; Then the above solution is added into the reaction kettle, the heating device is turned on to raise the temperature and the temperature is controlled at 100~200 °c for 18~36 hours; finally, the above solution was rapidly sprayed into deionized water at a temperature of 20 ° C. Through a nozzle, centrifuged and dried, and finally ultra-fine melamine borate was obtained. The melamine borate prepared by the preparation method has small particle size and uniform distribution, little influence on the mechanical properties of polymer matrix and high flame retardant efficiency.
