Abstract
The invention relates to a preparation method of a low-heat-conductivity and flame-retardant graphene expanding polystyrene board. The preparation method comprises the following steps: stirring and blending graphene, a flame retardant, a flame retardant adjuvant, activated calcium carbonate and polyvinyl alcohol to obtain a mixture, and grinding the mixture and styrene through a grinding machine till the fineness is 0.05 to 15 [mu]m to prepare uniformly dispersed slurry; adding water and a dispersing agent into a reaction kettle for uniform stirring, adding the prepared slurry and auxiliary materials such as an initiator and a nucleating agent, heating to the temperature of 88 to 92 DEG C, and carrying out low-temperature polymerization for 7 to 9 hours; sealing the kettle, adding a foaming agent, heating to the temperature of 118.5 to 123 DEG C, carrying out high-temperature polymerization for 3 to 6 hours, and ending the procedure till the temperature is constant; cooling the product to obtain graphene expanding polystyrene. The method avoids the phenomena of long polymerization period, difficulty in reaction control, easiness in kettle sticking due to high viscosity in a polymerization process and the like which are caused by adding additives such as graphite or the graphene in conventional synthesis of the expanding polystyrene, and the graphene expanding polystyrene board with the heat preservation effect and flame retardant performance which are higher than those of current graphite and a common white material.
