METHOD FOR PRODUCING LIGHT THERMAL INSULATION PANEL FOR SOUND DAMPING, MADE OF WASTE RUBBER POWDER AND ORGANIC SLUDGE AND INTERLAYER STRUCTURE USING THE SAME TO IMPROVE INTERLAYER SOUND DAMPING EFFECTS AND WORKABILITY

摘要

PURPOSE: A method for producing a light-weighted thermal insulation panel for sound damping, made of a waste rubber powder and organic sludge and an interlayer structure using the same are provided to prevent transfer of sound from the upper floor to the lower floor, to improve workability and environmental friendliness. CONSTITUTION: The method for producing a light-weighted thermal insulation panel for sound damping, made of waste rubber powder and organic sludge comprises: (S100) preparing a porous light-weighted aggregate having a diameter of 5-10mm by mixing 40-60vol% of organic sludge, 35-50vol% of clay and 0.5-10vol% of fly ash, forming the mixture into a spherical shape, and sintering it at high temperature such as 1000deg.C or more; (S110) mixing 30-40vol% of the resulted porous light aggregate, 28-35vol% of expanded vermiculite, 10-15vol% of cement, 5-10vol% of stone powder, 0.05-1vol% of an Al powder, 0.05-1vol% of fly ash and based on the amount of the cement, 45-50vol% of water; (S120) roughly packing and closing the mixture into a mold; (S130) foaming the mixture packed in the mold by steam-curing or wind dry; (S140) releasing the foamed article out of the mold and cooling it; (S150) applying thereto a waterproof adhesive agent of a polyamide resin to form a construction panel; and (S160) applying a fine powder of waste tire rubber ground to the size of 0.5-2mm to the joint part of the construction panels where the waterproof adhesive agent is applied.
