Abstract We present a new method for synthesizing cold‐resistant laminated anti‐fire glass using K 2 O· n SiO ‐based ultrathin flexible membrane, which is prepared by vacuum surface treatment with ball‐milled core–shell emulsion (55 wt%). systemically characterize the mechanical, optical, rheological, cold‐resistant, fire‐resistant, and weather‐resistant performances of this glass. The formation mechanism membrane studied in detail multispeckle diffusing–wave spectroscopy scanning electron microscopy. Then, tensile strength, plasticity, rheological behavior materials different moduli are characterized. Combined thermal gravity analysis, we compositions moduli. For appearance air‐conducting microchannels designed, resembling Wu Zhu coin morphology (a square hole circular ancient China) or honeycomb wall morphology. These structures endow visible region reduced presence microbubbles. As type building safety glass, spongelike microporous insulation layer can increase heat‐insulating time event fire. Furthermore, performance demonstrated to be more than 3000 h through an ultraviolet test. This work also provides routine high‐quality shapes, including curved surfaces.
