METHOD OF LIGHT-WEIGHT FOAMING ACOUSTIC ABSORBENT PANEL UASING A FLY-ASH AND THE LIGHT-WEIGHT FOAMING ACOUSTIC ABSORBENT PANEL MANUFACTURED BY THE METHOD

摘要

The present invention relates to a lightweight foamed sound absorption panel manufacturing method using fly ash and a lightweight foamed sound absorption panel manufactured by the same and, more specifically, to a lightweight foamed sound absorption panel manufacturing method using fly ash and a lightweight foamed sound absorption panel manufactured by the same capable of improving flexural strength, water repellency, a sound absorption function, deodorization, and an antibacterial ability without a whitening phenomenon. The present invention relates to a composite comprising: 4 to 8 parts by weight of an alkaline water-containing oxide; 1 to 5 parts by weight of an acid; 1 to 5 parts by weight of a strength reinforcing material; and 1 to 10 parts by weight of water for 100 parts by weight of a mixture having 50 to 80 wt% of the fly ash and 20 to 50 wt% of an alkali silicate. The lightweight foamed sound absorption panel manufacturing method using the fly ash comprises: a composite mixing and injecting step of mixing the composite during 5-10 minutes, and injecting the mixed composite into a mold; a moisture deodorizing and foaming step of instantly heating the mold at 100C within 8-10 seconds, and heating the same for 8-12 minutes to remove moisture and perform foaming after the composite mixing and injecting step; a curing step of heating the mold in an oven at 300C during 1-3 hours after the moisture deodorizing and foaming step, and manufacturing the lightweight foamed sound absorption panel; and a cutting step of cutting the lightweight foamed sound absorption panel manufactured through the curing step depending on a use purpose.
