Problems solved by technology

Physical inhibitors only change the physical conditions of coal and its environment, and cannot fundamentally eliminate the danger of coal spontaneous combustion. With the consumption and loss of the inhibitor, its inhibitory effect will gradually disappear. Disadvantages such as poor chemical effect and short decay period

Abstract

The invention discloses a foam copper modified compound inhibitor and a preparation method thereof. After mixing treatment of montmorillonite, nano-silicon dioxide, nano-silver and nano-carbon fiber,the modified montmorillonite is obtained, the modified montmorillonite is immersed in a dopamine solution, a thin film is formed in the surface, foam copper is loaded, the hydrophilicity of materialsis improved, finally plant extracts are immersed, and the weather resistance of the materials is improved. Compared with the prior art, the foam copper modified compound inhibitor is high in resistance effect and high in hydrophilic property, the environmental protection is achieved, the influence of territory, altitude, temperature and water quality is not prone to appearing, and agglomeration isnot prone to appearing.

Description

technical field [0001] The invention belongs to the field of inhibitors for preventing spontaneous combustion of coal, and in particular relates to a copper foam modified composite inhibitor and a preparation method thereof. Background technique [0002] Coal spontaneous combustion disaster is one of the safety problems that need to be solved urgently in coal mining and coal storage and transportation. At present, the chemical inhibitor fire prevention technology has become a basic technology for the prevention and control of spontaneous combustion fires in coal mines at home and abroad, and has been widely used. Inhibitor is a chemical substance that prevents coal oxidation and spontaneous combustion, also known as oxygen inhibitor. Inhibitor anti-fire is the use of certain inhibitors to spray in the goaf or press into the coal body to inhibit or delay the oxidation process of coal, so as to prevent the spontaneous combustion of coal. [0003] At present, technologies s...
