Problems solved by technology

[0004] Magnesium oxysulfate cementitious material is a relatively new type of air-hardening cementitious material. Its main feature is light weight and high strength. Products based on magnesium oxysulfide cementitious material have attracted extensive research, but for sound-absorbing Magnesium oxysulfide cementitious materials with noise reduction effect are rarely reported, and have become a blank in the building materials market

Abstract

The invention belongs to the technical field of building materials, specifically relates to a magnesium oxysulfate cementing material with sound absorption and noise reduction effects, and further discloses a preparation method of the magnesium oxysulfate cementing material. The magnesium oxysulfate cementing material is prepared from the raw materials of light calcined magnesia powder, magnesium sulfate, a water reducing agent, organic acid, fly ash, lignin and aeolian sand. The magnesium oxysulfate cementing material involved in the invention integrates fire prevention, fire resistance, light weight and high strength, and sound absorption and noise reduction properties, and solves the application problem of existing building materials; a produced product is wide in application, is particularly applicable to ball mills of factories, especially the inner walls and outer walls of coal milling ball mills as well as the outer surfaces of certain flammable walls and certain environments needing sound absorption, and has relatively good application prospects.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a magnesium oxysulfide gelling material with sound-absorbing and noise-reducing functions, and further discloses a preparation method thereof. Background technique [0002] With the development of modern industry, environmental pollution has also emerged. Noise pollution is a kind of environmental pollution, which has become a major hazard to human beings. At present, noise pollution, water pollution, and air pollution are regarded as three major environmental problems worldwide, posing a serious threat to the quality of human life. [0003] The sound absorption effect of objects is universal. During the propagation of the sound wave, if it encounters a barrier, part of it will be reflected and the other part will be absorbed. The sound absorption effect of an object is not only related to the sound-absorbing material but also to the selected sound-absorbi...
