▎ 摘  要

NOVELTY - Gypsum board with super sound insulation effect comprises 3-5 wt.% modified starch, 0.2-0.5 wt.% retarder, 0.1-0.2 wt.% water reducing agent, 0.5-2 wt.% air-entraining agent, 2-5 wt.% modified graphene oxide, 5-8 wt.% magnesium aluminum hydrotalcite, and desulfurization gypsum powder (balance). USE - Used as gypsum board with super sound insulation effect. ADVANTAGE - The method: improves the consumption of sound waves by the gypsum board; and achieves the effect of super sound insulation. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing gypsum board with super sound insulation effect.
