Abstract

The invention discloses a preparation method of an ionic flame-retardant composite material. The invention polymerizes monomers cross-linked by phosphating diatomite, so that diatomite is well compatible with polymers, does not form agglomeration, and improves The stability strength of the finished material is improved; the diatomite microporous structure and polymer foam structure of the present invention effectively improve the thermal insulation performance of the finished material, and the diatomite can effectively block the transfer of heat, and the phosphorus-containing monomer, The blending of ionic liquids has a good synergistic flame retardant effect.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a preparation method of an ion flame-retardant composite material. Background technique [0002] Polystyrene foam is a lightweight material made of polystyrene resin as the base material, adding foaming agent and other auxiliary materials, and foaming by heating. It has the advantages of light weight, small thermal conductivity, low water absorption, water resistance, aging resistance, low temperature resistance, easy processing, low price and high quality. However, polystyrene foam insulation materials bring great convenience to people's lives. Flammability also brings certain limitations to its application. Polystyrene foam itself is a flammable material, and it is easy to decompose and burn under fire and high temperature conditions. [0003] And accompanied by a large amount of toxic gas. Therefore, it is urgent to carry out research work on the fire safety of polystyr...
