The invention discloses sunscreen laminated glass for a car window, and relates to the technical field of glass. A compound synthesized from 4-methoxycinnamic acid, 2-hydroxy-5-(2-ethoxyl) benzaldehyde and para aminobenzoic acid is intercalated into magnesium-aluminum hydrotalcite, a cinnamate structure and a Schiff base structure are introduced between layers of the magnesium-aluminum hydrotalcite, and ultraviolet light is effectively absorbed by combining the ultraviolet shielding effect of the hydrotalcite, so that the ultraviolet barrier property of the laminated glass is preliminarily realized; the preparation method comprises the following steps: preparing hydrotalcite, further modifying the hydrotalcite by using KH151, polymerizing with acrylic acid, acrylamide and chitosan to form self-adhesive hydrogel, bonding glass and forming a sandwich structure, sequentially sputtering and depositing a titanium dioxide film, a silicon dioxide film and a tin antimony oxide film on the surface of the sandwich glass to form a three-layer composite film, and constructing a sunlight filtering system. Transmission of ultraviolet light and infrared light is reduced, heat rays are greatly reflected, and a heat insulation structure is formed.
本发明公开了一种车窗用防晒夹层玻璃,涉及玻璃技术领域。本发明利用4‑甲氧基肉桂酸、2‑羟基‑5‑(2‑羟乙基)苯甲醛、对氨基苯甲酸合成的化合物插层于镁铝水滑石,在其层间引入肉桂酸酯结构和席夫碱结构,结合水滑石的紫外屏蔽作用,有效吸收紫外光,初步实现夹层玻璃的紫外阻隔性能;然后利用KH151对水滑石进一步改性,再与丙烯酸、丙烯酰胺、壳聚糖聚合形成自粘性水凝胶,粘结玻璃,形成夹层结构,接着,在夹层玻璃表面依次溅射沉积二氧化钛、二氧化硅、氧化锡锑膜层,形成三层复合膜层,构建太阳光过滤体系,减少紫外、红外光透过,大幅度反射热射线,形成隔热结构。
