The grade of MgO of crude improves to 63.22% from 61.33% using brucite in liaoning province as the material by winnowing. The surface of Mg(OH)2 flame retardant is treated with four kinds of coupling agent,they are silane172,silane151,titanate NT-105 and composite coupling agent(silane172 being 66.7%,and zinc stearate being 33.3%)on the condition of usage of coupling agent being 0.5%、1.0%、1.5% and 2.0%,activating time being 3、6、9 and 12min,and the specific surface area,tensile strength,rate of absorbing water and oxygen index are measurated.The results showed the silane172 at the dosage of ≤1.5%, activating time 6-9min is feasible.Quality of its products can be comparable with synthetic products. Natural brucite is the ideal material for flame-retardant products.
