METHOD FOR MANUFACTURING EXPANDABLE STYRENE POLYMER CONTAINING ALUMINIUM PARTICLES, AND EXPANDABLE STYRENE POLYMER PRODUCED THEREBY

摘要

The present invention relates to: a foamable styrene polymer which is obtained by blending aluminum particles in a polystyrene resin and impregnating a foaming agent, for producing polystyrene beads for the production of a foamed body without the transformation by direct sunlight while maintaining insulation material properties including thermal conductivity, absorption rate, and strength; and a production method of the same. The foamed body foamed by the foamable styrene polymer satisfies mechanical properties for an insulation material, has low thermal conductivity to offer excellent thermal insulation properties, and presents the degradation of the insulation material containing black ingredients with athermancy by being exposed to direct sunlight, thereby being effectively used as the insulation material for construction.
