▎ 摘  要

NOVELTY - Preparing ceramsite sound-absorbing panels comprises (i) weighing the thermosetting resin, adding curing agent equivalent to 75-85 wt.% thermosetting resin, 1-3 wt.% accelerator and 60-70 wt.% diluent into the thermosetting resin, stirring at 200-250 revolutions/minutes for 1-2 minutes at 80-100 degrees C to obtain resin mixed bonding solution with good fluidity, (ii) dispersing graphene oxide powder equivalent to 0.3-3 wt.% of the mass fraction of the resin mixing and bonding solution in 100 ml solvent to obtain graphene oxide dispersion by ultrasound, (iii) adding the graphene oxide dispersion obtained in step (ii) to the resin mixed and bonding solution obtained in step (i), and stirring for 30-60 seconds at a speed of 200-250 revolutions/minute at 80-100 degrees C to obtain a mixed melt. USE - The method is useful for preparing ceramsite sound-absorbing panels. ADVANTAGE - The method enables preparation of ceramsite sound-absorbing panel with excellent sound-absorbing effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for ceramsite sound-absorbing panels prepared by the above preparation method.
