Laminated Structure And Vacuum Insulating Material Including The Same

A laminated structure includes a polymer layer comprising at least one layer, a gas barrier layer which has thermal resistance of greater than or equal to about 650 degrees Kelvin per watt and a Young's modulus of greater than or equal to about 100 gigapascals, and a position of a neutral axis represented by the following Equation 1 is in the gas barrier layer. y = Sigma i = 1 n ( Ei*Si ) Sigma i = 1 n ( Ei*Ai ) ( Equation 1 ) In Equation 1, y denotes a distance from the top surface of a side compressed in bending to the neutral axis, Ei denotes a Young's modulus of the i-th layer, Si denotes a geometrical moment of area of the i-th layer, Ai denotes a cross-sectional area of the i-th layer, and n denotes a number of layers for the laminated structure, which is an integer of greater than or equal to 5. 公开了层叠结构体和包括其的真空绝热材料。所述层叠结构体能够有效地减少热桥和增强可使用性以及抑制针孔和裂纹的产生，并且顺序地包括包含至少个层的聚合物层、气体阻隔层、和包含至少个层的聚合物层，同时在层之间插入胶粘层，其中所述气体阻隔层具有大于或等于约650K/W的热阻和大于或等于约100GPa的杨氏模量；并且由以下方程1表示的中性轴的位置在所述气体阻隔层中。在方程1中，y为从在弯曲时被压缩侧的顶部表面到所述中性轴的距离，
