Insulating material for outer wall and process for preparing the same

摘要

The present invention relates to an insulation material for an external wall and a manufacturing method thereof. To be more specifically, an insulation material for an external wall is formed by repeatedly stacking an expandable polystyrene layer and a thermal barrier adhesive layer, wherein the expandable polystyrene layer having a thin plate shape is manufactured by filling a fire retardant binder in expandable polystyrene coated by a coating agent. Therefore, the insulation material for an external wall can remarkably improve insulation features of the conventional Styrofoam by attaching an insulation attaching substance to the expandable polystyrene in three dimensions and, at the same time, can be conveniently used according to the purpose of use of a user by being formed of an eco-friendly material.
