The invention discloses a gypsum board with an ultra-strong sound insulation effect. The gypsum board is prepared from the following components in percentage by weight: 6-10 percent of modified starch, 0.2-0.5 percent of retarder, 0.1-0.2 percent of water reducing agent, 0.5-2 percent of air entraining agent, 0.1-0.2 percent of modified graphene oxide, 1-3 percent of magnesium-aluminum hydrotalcite and the balance of desulfurized gypsum powder. In order to achieve an ultra-strong sound insulation effect, magnesium-aluminum hydrotalcite with a layered structure is added into the gypsum board disclosed by the invention; meanwhile, the organic silicon modified starch reacts with the desulfurized gypsum powder in the gypsum board, and a film-shaped structure is formed on the basis of the silane modified graphene oxide, so that the consumption of sound waves by the gypsum board is further improved, and finally, the ultra-strong sound insulation effect is achieved.
本发明公开了一种具有超强隔音效果的石膏板，由以下重量百分比的成分组成：改性淀粉6‑10%、缓凝剂0.2‑0.5%、减水剂0.1‑0.2%、引气剂0.5‑2%、改性氧化石墨烯0.1‑0.2%、镁铝水滑石1‑3%和脱硫石膏粉余量。为了达到超强的隔音效果，本发明的石膏板中加入了具有层状结构的镁铝水滑石；同时在石膏板中有机硅改性淀粉与脱硫石膏粉反应，并在硅烷改性氧化石墨烯的基础上形成膜状结构，从而进一步提升了石膏板对声波的消耗，最终达到超强隔音的效果。
