FLAME-RETARDING COMPOSITION USING WASTE POWDER OF ARTIFICIAL MARBLE AND COAL ASH, AND METHOD OF PREPARING THE SAME

摘要

A flame-retarding composition is provided to reduce processing costs of waste and to be environment-friendly by recycling artificial marble waste powder and coal ash, and to prepare non-toxic flame retardant product which is suitable for international environment standard. A flame-retarding composition comprises coal ash 0~120 phr, artificial marble waste powder 0~120 phr, ethylene vinylene aceta 0~20 phr, ammonium polyphosphate 0~7 phr and magnesium hydroxide 30~200 phr based on the polymer resin 100.0 phr. A method for manufacturing the flame-retarding composition comprises the steps of: (a) solution coating coal ash, artificial marble powder or combination thereof with a compatibilizer solution, drying and filtering the product; and (b) mixing the dried coal ash or artificial marble powder with a flame-retardant aid, compatibilizer and polymer resin.
