The invention discloses a light composite sound absorption and insulation board which comprises a sound absorption and insulation board body and a supporting mechanism; the sound absorption and insulation board body is prepared from broken ceramsite with the particle size being 2.5-4.5 mm and perlite, wherein the perlite is perforated perlite, and the particle size of the perlite is 0.8-1.5 mm. The beneficial effects are that the light composite sound absorption and insulation board meets requirements of highway and railway rail transit, industrial power plants and municipal square places forlight, A-grade fireproof and noise-reducing materials, and meanwhile, has the effects of attractive appearance and adjustable facial patterns; in the plate structure, combined distribution of two kinds of hole diameters and sound absorption cavity materials is adopted, and through stepped changes of large surface layer holes and small bottom layer holes, the thickness of a material layer and the characteristics and distribution of sound absorption cavities can be adjusted according to the characteristic frequency of a noise source, so that the sound absorption performance of the materials is optimized; and through the designed supporting mechanism, the sound absorption and insulation board body is supported, so that the sound absorption and insulation board body is fixed stably.
本发明公开了一种轻质复合吸隔声板，包括吸隔声板本体和支撑机构，所述吸隔声板本体由颗粒粒径破碎陶粒与珍珠岩配制而成，其中破碎陶粒的颗粒粒径为2.5‑4.5mm；珍珠岩为开孔珍珠岩，粒径为0.8‑1.5mm；本发明的有益效果是：满足公路、铁路轨道交通、工业电厂、市政广场场所对轻型、A级防火、降噪材料的需求，同时具有美观和面部花纹可调的效果；板结构中采取了两种孔径与吸声腔材料的组合分布，面层孔大，底层孔小的阶梯变化，可以针对噪声源的特征频率，调整材料层厚度和吸声腔特征以及分布，从而达到优化材料吸声性能；通过设计的支撑机构，起到对吸隔声板本体的支撑，使得吸隔声板本体固定稳固。
