RECYCLED POLYESTER(PET) POLYMER CONCRETE COMPOSITION USING HIGH PERFORMANCE NANOMATERIALS AND PRODUCTION METHOD THEREOF

摘要

PURPOSE: Provided is a production method of recycled polyester(pet) polymer concrete with heat resistance and water repellency by using recycled pet-based unsaturated polyester resin and high performance nanomaterials. CONSTITUTION: The recycled pet polymer concrete composition comprises the components of: 5-30wt.% of recycled pet-based unsaturated polyester resin as a binder; 5-30wt.% of filling material such as potassium bicarbonate or fly ash for good adhesive power due to increase of viscosity; 40-90wt.% of aggregate containing fine aggregate(0.074-5mm size) and coarse aggregate(5-50mm size); and 0.01-30wt.% of nanomaterials having a 0.01nanometer-100micrometer size, wherein the nanomaterials for heat-resistance are borides, carbides or nitrides of metal selected from the group consisting of Si, Al, Zr, Sc, La, Se, Nd, Y, etc. and the nanomaterials for water repellency are F, SiO2, etc. The composition is produced by mixing the above materials and curing mixtures at room temperature(17-23deg.C) or 50-2000deg.C over 24hrs.
