Heavy high-strength sound absorption porous ceramic material and preparation method thereof
The invention discloses a heavy high-strength sound-absorbing porous ceramic material and a preparation method thereof, and belongs to the technical field of ceramic materials, and the preparation method comprises the following steps: step 1, pretreating feldspar powder, a foaming agent, perlite and magnesium oxide; step 2, pretreating feldspar powder, a foaming agent, perlite and magnesium oxide, and mixing the pretreated feldspar powder, foaming agent, perlite and magnesium oxide with other raw materials in parts by weight; according to the invention, the prepared ceramic material has excellent sound absorption performance, the pretreated perlite and the prepared foaming agent are taken as main raw materials, the prepared ceramic material presents a multi-layer structure with different thicknesses and different pore sizes, and the pore sizes of the ceramic material are changed, so that the viscous resistance of sound waves is effectively increased; according to the present invention, the surface of the perlite is treated by using the silane coupling agent as the modification modifier, and the pretreated perlite is used as the main base material, such that the prepared ceramic material has excellent sound absorption property.
本发明公开了一种重质高强吸声多孔陶瓷材料及其制备方法，属于陶瓷材料技术领域，包括如下制备方法：步骤1：对长石粉、发泡剂、珍珠岩和氧化镁进行预处理；步骤2：将长石粉、发泡剂、珍珠岩和氧化镁进行预处理与其它原料按重量份配比进行配料。本发明中，使制备的陶瓷材料获得优异的吸声性能，由经过预处理的珍珠岩和制得发泡剂为主要原料，制备的陶瓷材料将会呈现不同厚度不同孔径大小的多层结构，通过改变其孔径大小，有效增加了声波的粘滞阻力，大大提高了陶瓷材料的吸声性能，以硅烷偶联剂为修饰改性剂对珍珠岩的表面进行处理，以经过预处理后的珍珠岩作为主要基料，制得的陶瓷材料具有优良的吸声特性。
