PURPOSE: An air permeable ceramic rubberized film waterproof material is provided, which waterproof material shows good heat insulation efficiency without deterioration of the basic physical properties as a film waterproof material. CONSTITUTION: The air permeable ceramic rubberized film waterproof material is prepared by adding dioctyl phthalate as a plasticizer to asphalt heated to 150-180 deg.C; adding a coumarone indene resin and a thermoplastic elastomer to the asphalt to dissolve them; adding rubber powder of 15-50 mesh as a filler to the asphalt and mixing them to prepare an asphalt film waterproof material containing a thermoplastic elastomer; and adding 10-15 parts by weight of porous ceramic powder with a particle size of 150-300 micrometers to 100 parts by weight of the obtained asphalt film waterproof material containing a thermoplastic elastomer. The porous ceramic powder has a density of 0.6-0.8, the oil absorption value of 16g/100g, a boiling point of 1,200-1,600 deg.C and heat conductivity of 0.11 W/mk. Preferably the thermoplastic elastomer is styrene-butadiene-styrene. |
