AI Technical Summary

Technical Problem

Traditional building-integrated photovoltaic (BIPV) curtain walls generate severe glare and heat accumulation under strong sunlight, affecting urban traffic safety, residents' lives and energy efficiency, and existing solutions cannot be dynamically adjusted.

Method used

The encapsulation film, which includes a matrix resin, crosslinking agent, initiator, silane coupling agent, anti-aging additive, retroreflective glass microspheres and reversible light-changing filler, is driven by solar irradiation to dynamically adjust light and heat management, thereby achieving anti-glare during the day, auxiliary lighting at night, and all-day heat insulation and energy saving.

Benefits of technology

It effectively reduces glare index, minimizes heat transfer, achieves zero-energy intelligent adjustment, improves energy efficiency and comfort, while maintaining power generation capacity and aesthetic appeal.

Abstract

The application provides a curtain wall assembly for automatically adjusting a glare effect and a preparation method thereof, and the curtain wall assembly comprises a battery piece, a front plate glass and a transparent back plate, the battery piece is encapsulated between the front plate glass and the transparent back plate through an encapsulation adhesive film; the encapsulation adhesive film comprises the following components in percentage by mass: a base resin: 80-90%; a crosslinking agent: 4-8%; an initiator: 0.5-2%; a silane coupling agent: 0.5-1%; an anti-aging auxiliary agent: 0.5-2%; reverse reflection glass microbeads: 3-5%; and reversible light conversion fillers: 4-10%. When solar irradiation is enhanced, the reversible light conversion fillers reversibly change the molecular structure, when the light is weakened, the material restores the transparent state, and the light and heat can be dynamically and intelligently managed, so that the day is prevented from glare, the night is assisted with illumination, and the whole day is heat-insulated and energy-saving.
