PURPOSE : Provided is a yellow earth panel composition with sound absorption, lightweight, nonflammability and water resistance for use as construction interior material by using lightweight inorganic material and yellow earth as main materials. CONSTITUTION : The sound-absorbing panel composition comprises 40-95wt.% of lightweight inorganic material(0.1-10mm) such as perlite, vermiculite or diatomite, 1-70wt.% of yellow earth, 0.01-10wt.% of polyester(PET) fiber, 2.5-50wt.% of liquid inorganic binder such as sodium silicate, silica sol or alumina sol, and 0.01-30wt.% of aqueous thermal-hardened phenolic resin for water resistance. The constructional panel is manufactured by the following steps of : preparing a liquid binder obtained by mixing inorganic binder and phenolic resin homogeneously; adding lightweight inorganic material, yellow earth and PET fiber to the mixed binder; and hot-pressing mixtures at 250-300deg.C under pressure of 0.1-10kgf/cm2. The resultant yellow earth panel composition is widely used as panel material for sound-absorbance, sandwich, fire door, etc. © KIPO 2005
