Problems solved by technology

However, the anti-seepage garbage tank and leachate tank have many layers, the construction is complex, time-consuming, and the anti-corrosion and tolerance are average. It is difficult to adapt to the increasingly complex composition of domestic waste, the increasing corrosion, and the increasingly harsh service environment of the garbage tank. conditions of use

Abstract

The invention discloses a garbage pool coating and a preparation method thereof, the coating comprises a cement concrete base layer, an anticorrosive layer, an impervious layer and a wear-resistant and impact-resistant layer, and the coating is prepared by adopting a mode of combining a high-pressure airless spray gun and manual blade coating. The layered structure design is adopted, independent functional design emphasis is achieved for each layer, the prepared garbage pool coating is high in overall bonding strength, excellent in anti-stripping performance, high in hardness, excellent in wear resistance and impact resistance, excellent in anti-seepage performance, anti-corrosion performance and anti-aging performance and high in tolerance to household garbage, and in addition, the service life of the garbage pool coating is prolonged. The preparation method disclosed by the invention is simple, high in mechanical degree, high in efficiency, short in time consumption, high in construction workability and stable in quality, can well avoid potential quality hazards on a construction site, and remarkably prolongs the service life of the garbage pool.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof, in particular to a garbage pool coating and a preparation method thereof. Background technique [0002] As one of the key facilities for the normal operation of the domestic waste incineration power plant, the garbage pond is in direct contact with the domestic garbage. Compared with other cement concrete buildings, the coating on the inner and outer surfaces has a good anti-corrosion, impermeability, wear resistance and impact resistance. higher requirement. However, the existing garbage pond coating has a single function and cannot take into account all performance requirements, which leads to easy occurrence of hidden quality problems, reduced service life and increased maintenance frequency. Once the garbage pond starts to operate, it is extremely difficult and economical to interrupt the work for maintenance. The loss is extremely high, and it will cause secondary pollution, whi...
