FLAME RETARDANT EMULSION MODIFIED POLYMERIC MATERIAL FOR WOODEN MODEL AND PROCESS FOR PRODUCTION OF MODIFIED POLYMERS

摘要

A flame retardant water-soluble modified polymer for wooden pattern, and its preparation method are provided to obtain flame retardancy, solvent resistance and hardness and to allow post-process to be carried out easily. A flame retardant water-soluble modified polymer for wooden pattern comprises 10~87 wt% of soluble glass; 10~40 wt% of a hydrophilic polyol mixture; 1~20 wt% of di-n-butyl phthalate; 1~15 wt% of an inorganic filler; and 1~15 wt% of an emulsion acrylic resin. The preparation method of the modified polymer comprises the steps of preparing a hydrophilic polyol mixture; injecting di-n-butyl phthalate to the hydrophilic polyol mixture and heating and mixing the mixture; injecting an emulsion acryl resin to the mixture at 80~90 °C, and stirring it with 1000~3000 rpm for 60 min; and injecting soluble glass and an inorganic filler to the stirred one at 80~90 °C, and mixing and stirring it with 1000~3000 rpm for 30~60 min.
