AI Technical Summary

Technical Problem

Existing heat insulation walls have limited heat insulation effects, and the exposed wall surfaces are easily affected by environmental factors such as sunlight, which can cause surface cracking and bulging. Repairs cannot be carried out in a timely manner due to weather conditions.

Method used

Design an insulated wall coated with a radiative cooling coating, comprising a wall base, a fixing frame, an adhesive layer, a phase change layer, a heat insulation layer, a radiative cooling coating layer, and a protective layer. Through a modular multi-level functional structure combination, the adhesive layer fixes the fixing frame, the phase change layer buffers temperature changes, the heat insulation layer increases the thickness, the radiative cooling coating layer reflects solar radiation, and the protective layer protects the coating layer.

Benefits of technology

It enhances the heat insulation and airtightness of the wall, extends its service life, facilitates the repair and replacement of damaged walls, and improves the practical value of the wall.

Abstract

The utility model relates to the technical field of heat insulation wall, especially a heat insulation wall coated with radiation refrigeration coating, which comprises a wall base layer, a fixed frame arranged on the outer side of the wall base layer, an adhesive layer arranged on the inner side of the fixed frame, a phase change layer arranged on the outer side of the adhesive layer, a heat insulation layer arranged on the outer side of the phase change layer, a radiation refrigeration coating layer arranged on the outer side of the heat insulation layer, and a protective layer arranged on the outer side of the radiation refrigeration coating layer. The fixed frame is fixed on the wall base layer through the adhesive layer, the fixed frame is used to conveniently disassemble, replace and maintain the heat insulation wall surface, the radiation refrigeration coating layer effectively reflects solar radiation, reduces the temperature of the wall, the protective layer is used to protect the radiation refrigeration coating layer, the heat insulation layer increases the thickness of the wall, the phase change layer buffers the temperature change of the wall, and the stress generated by thermal expansion and cold contraction of the wall can be reduced, thereby enhancing the heat insulation effect of the wall. Moreover, the heat insulation wall can be locally disassembled and assembled, and the damaged and aged wall surface can be repaired and replaced at any time.
