Abstract

A low-cost ecological ceramic material with multiple sound-absorbing structures disclosed by the invention comprises the following components: 22%-27% of fly ash, 13%-18% of coal gangue, 8%-12% of red mud, and Rock 40%-45%, feldspar 5%-10%, foaming agent 0.2%-2%, binder 0.5%-3%, pore-forming agent 7%-12%, surfactant 0%-1% ; With a variety of pore structures, it absorbs water vapor in the environment and adjusts the air humidity. The invention also discloses the preparation method of the ceramic material, through mechanical drilling, pore-forming agent and foaming agent three kinds of pore-forming methods, respectively forming a perforated plate sound-absorbing structure, a micro-perforated resonance sound-absorbing structure and a thin-plate resonance sound-absorbing structure The structure increases the porosity of the opening of the material, improves the high-frequency sound absorption effect, and various sound-absorbing structures improve the sound absorption effect of the medium and low frequencies, and the cost of raw materials is low, which is in line with environmental protection and globalization.

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 ...
