Boron nitride intumescent fire retardant coating with borax and melamine as the main components was experimentally studied. The formulation of coating was designed by orthogonal experiment; fire resistance time was tested in the intumescent fire retardant coating testing furnace; the micro-structure of the coating was studied by SEM. Experimental results showed that: after heated, a layer of dark green, compact lazed B2O3 formed on the surface of intumescent coating; and a structure of porous spongy BN formed in the inner of coating. This structure makes the coating has a high resistance to heat. But because the melting point of borax is low, the coating can't withstand high temperature, it will soften at high temperatures. This has seriously affected the fire resistance time of the coating. The method for solving this problem is to find a new kind of nitrogen containing compounds, which makes the reaction of borax to boron nitride more easily. The experiments prove that, intumescent fire retardant coating with borax and nitrogen containing compound is feasible.
