摘要
The present invention relates to a method for producing an inorganic hydroxide-silica hybrid composite flame retardant for a polymeric resin having excellent flame retardancy and a composite flame retardant prepared by the method. More particularly, the present invention relates to a silica hybrid compound containing silica and a urethane group, Or inorganic hydroxide particles such as magnesium hydroxide are combined with each other so that an endothermic reaction by an inorganic hydroxide and a flame retarding mechanism such as foam insulation and heat resistance enhancement by the nano silica contained in the silica hybrid compound can be simultaneously exhibited, The composite flame retardant is not only halogen-free, but also environmentally friendly. It is also excellent in dispersibility in the polymer resin due to the organic moiety of the urethane group contained in the silica hybrid compound, and the silicate hybrid compound has a nano-size High according to Relates to a complex flame retardant manufactured by the manufacturing method and the hybrid method of the silica composite flame-retardant - it is possible to obtain the effect of soft-retardant efficiency is excellent polymer resin to the inorganic hydroxide to achieve a cost reduction.
