Document Type and Number:
WIPO Patent Application WO/2022/143849
Kind Code:
A1
Abstract:
Disclosed is a method for preparing an energy-saving, fireproof and sound-insulating wall material using sludge solid waste combined with industrial slag. The preparation method comprises the following step: material selection: 10-15 parts of sludge solid waste; 20-25 parts of iron ore slag; 4-7 parts of sodium carbonate; 25-50 parts of coal ash; 4-16 parts of a silicon source material; 8-12 parts of organic matter; 0.1-0.25 parts of a modifier; 0.1-0.25 parts of a foam stabilizer; and 10-15 parts of perlite. The wall body made by the method internally comprises air holes formed after sodium carbonate maintenance and cracks inside perlite. After sound transmission, the internal cracks enable sound waves to be converted into thermal energy through fine holes of the material, thereby achieving a sound absorption effect. In addition, the wall body as a whole is made of a non-combustible substance, and has good fireproof performance.
