Through analyzing and researching the current situation of fire-retardant coatingsand elastomers both at home and abroad,in order to resolve the problem of flameretardant durability of the materials,bromine carbon polyurethane resin was preparedby molecular design and material design and was used in steel structure fire retardantcoatings and elastomer.Excellent property of fire-retardant materials was prepared andachieved the purpose of long-term efficient flame retardant.
The low molecular weight of t...
