Ceramsite acoustic board and preparation method thereof
The invention relates to a ceramsite acoustic board and a preparation method thereof. The preparation method comprises the following steps: preparing a resin mixed bonding solution by adding a curingagent accounting for 75-85 wt% of the mass fraction of thermosetting resin, an accelerant accounting for 1-3 wt% of the mass fraction of the thermosetting resin and a thinner accounting for 60-70 wt%of the mass fraction of the thermosetting resin into the thermosetting resin and stirring, dispersing 0.3-3 wt% of graphene oxide powder equivalent to the mass fraction of the resin mixed bonding solution into 100 ml of solvent, performing ultrasonic treatment to obtain graphene oxide dispersion liquid, adding the graphene oxide dispersion liquid into the resin mixed bonding solution, and stirringto obtain a mixed molten liquid, adding the mixed molten liquid into a certain amount of mixed aggregate, stirring to obtain a mixture, pouring the mixture into a mold, paving the mold with the mixture, carrying out vibration compaction, carrying out a reaction for a period of time at a certain temperature to obtain a sound absorption plate base layer, and carrying out hydrophobic treatment on the outer side of the sound absorption plate base layer, so that the outer surface of the sound absorption plate base layer is coated with the hydrophobic layer, and the ceramsite sound absorption plateis obtained.
本发明涉及一种陶粒吸声板及其制备方法，包括以下步骤：制备树脂混合粘接溶液：将分别相当于热固性树脂质量分数75‑85wt%的固化剂、1‑3wt%的促进剂、60‑70wt%的稀料加入至热固性树脂中，搅拌后得到树脂混合粘接溶液；将相当于树脂混合粘接溶液质量分数0.3‑3wt%的氧化石墨烯粉末分散在100ml溶剂中超声得到氧化石墨烯分散液；将氧化石墨烯分散液加入至树脂混合粘接溶液中，搅拌后得到混合熔融液；将混合熔融液加入至一定量的混合骨料中搅拌后得到拌合料；将拌合料倒入模具中并铺满模具，经振动压实后在一定的温度下反应一段时间得到吸声板材基础层；对吸声板材基础层的外侧做憎水处理，使得憎水层包覆在吸声板材基础层的外表面，得到陶粒吸声板。
