Low-cost ecological ceramic material having a plurality of sound absorbing structures and preparation method thereof

Abstract

The invention discloses a low-cost ecological ceramic material having a plurality of sound absorbing structures. The low-cost ecological ceramic material having the plurality of sound absorbing structuresis prepared from the following components: 22% to 27% offly ash, 13% to 18%ofcoal gangue, 8% to 12% ofred mud, 40%to 45% ofshale, 5%to 10% offeldspar, 0.2%to 2% of foaming agent, 0.5%to 3% of binder, 7%to 12% of pore forming agent, and 0% to 1% ofsurfactant; a variety of pore structures are arranged, and water vapor in the environment is absorbed to adjust the humidity of the air. The invention further discloses a preparation method of the low-cost ecological ceramic material.A perforated plate sound absorbing structure, a microperforated resonance sound absorbing structure, and a thin plate resonance sound absorbing structure are formed by three pore-forming methods of mechanical punching, pore forming agent, and foaming agent respectively, the open porosity of the material is increased, the high-frequency sound absorption effect is improved, the plurality of sound absorbing structures improve the sound absorption effect of the low and medium frequency, the preparation material islow in cost, and the environment-friendly effect is conformed.

Description

technical field

[0001] The invention belongs to the technical field of ecological ceramic materials for municipal buildings, specifically relates to a low-cost ecological ceramic material with various sound-absorbing structures, and also relates to a preparation method of a low-cost ecological ceramic material with various sound-absorbing structures Background technique

[0002] With the development of my country's industrialization and the increase of the intensity of natural development, my country's environmental problems have become increasingly prominent. A large amount of industrial solid waste has accumulated, polluting land and water. Noise pollution, light pollution, and the uneven distribution of water resources caused by climate change have caused difficulties caused by excessively dry air in the north and humidity in the south. To reduce and eliminate environmental noise, the most commonly used is porous sound-absorbing material. Among them, the use of organic ...
