Novel sound barrier plate
The invention relates to a novel sound barrier plate, and belongs to the field of buildings and engineering. The formula comprises a bottom layer material formula and a surface layer material formula, wherein the bottom layer material formula comprises the following components in percentage by mass: 38-50% of diatomite; 15-30% of blast furnace slag; 5-12% of calcite; 2-6% of calcined talc; 2-5% of potassium feldspar; 3-8% of kaolin; 5 to 13% of bentonite; 5-10% of quartz; 2-6% of iron oxide red; 0.2%-0.8% of a foaming agent; 0.1 to 0.4 percent of a water reducing agent; the formula of the surface layer material comprises the following components in percentage by mass: 32-55% of perlite micro powder; 15-27% of calcined talc; 17 to 27% of bentonite; 4-10% of kaolin; 0.1-0.3% of a foaming agent; 0.1 to 0.4 percent of a water reducing agent; the preparation method of the sound barrier plate adopts a secondary material distribution forming process. The foamed ceramic composite sound barrier plate is of a double-layer structure and is provided with the sound insulation back plate; and through high-temperature firing, layering and cracking are avoided in use. The bottom-layer material replaces a base plate, so that the process production cost is reduced; the surface of the bottom layer material is flat after foaming and firing, cutting is not needed, and material waste is reduced. According to the invention, blast furnace slag is used as a raw material, which is an effective way for turning blast furnace slag into wealth.
本发明涉及一种新型声屏障板，属于建筑和工程领域。其配方分为底层料配方和面层料配方，所述底层料配方的质量百分比为：硅藻土38‑50％；高炉矿渣15‑30％；方解石5‑12％；烧滑石2‑6％；钾长石2‑5％；高岭土3‑8％；膨润土5‑13％；石英5‑10％；铁红2‑6％；发泡剂0.2‑0.8％；减水剂0.1‑0.4％；所述面层料配方的质量百分比为：珍珠岩微粉32‑55％；烧滑石15‑27％；膨润土17‑27％；高岭土4‑10％；发泡剂0.1‑0.3％；减水剂0.1‑0.4％；所述声屏障板制备方法采用二次布料成型工艺。本发明所得发泡陶瓷复合声屏障板，双层结构，自带隔音背板；高温烧制，使用中不会分层开裂。底层料取代垫板，降低了工艺生产成本；底层料发泡烧制后表面较平整，无需切割，减少了材料浪费。本发明采用高炉矿渣作为原料，是将高炉矿渣变废为宝的一种有效途径。
