The invention relates to the technical field of sound-absorbing building materials, and provides a building porous brick with an efficient sound-absorbing function and a preparation method thereof. Compared with a traditional method, the interior of the prepared porous brick has a three-dimensional pore channel structure, and the pore diameter is gradually reduced from outside to inside. The apertures are optimized, namely, the surface aperture is 3-3.5 mm, the middle aperture is 1-1.5 mm, and the apertures are gradually reduced from outside to inside, so that sound waves easily enter the porous brick and can generate more contact with the surface of a pore channel to consume more energy, and the sound absorption effect of the porous brick is improved.
本发明涉及吸音建筑材料的技术领域，提供了一种具有高效吸音功能的建筑用多孔砖及制备方法。与传统方法相比，本发明制得的多孔砖内部具有三维立体孔道结构，并且从外向内孔径逐渐减小。通过对孔径进行优化，即表面孔径为3~3.5mm，中间孔径为1~1.5mm，从外向内孔径逐渐减小，使得声波既容易进入多孔砖内部，又能与孔道表面产生更多接触而消耗更多能量，因此提高了多孔砖的吸音效果。
