The invention discloses impact-resistant laminated glass and a preparation process, the impact-resistant laminated glass comprises a first glass layer, a second glass layer and a composite middle layer arranged between the first glass layer and the second glass layer, and the composite middle layer comprises a stress concentration layer, a stress diffusion layer and a third glass layer arranged between the stress concentration layer and the stress diffusion layer; the thickness ratio of the stress concentration layer to the third glass layer to the stress diffusion layer is (0.6-1): (1: 1)-(1.5); the second glass layer serves as the outer side of the vehicle window and has excellent impact resistance under the assistance of the stress diffusion layer, the first glass layer serves as the inner side of the vehicle window and can easily break the whole piece of laminated glass from the interior of the vehicle under the assistance of the stress concentration layer, the safety of the vehicle is guaranteed, and meanwhile it is guaranteed that under the extreme driving environment, the whole piece of laminated glass can not be broken easily. Self-rescue of drivers and passengers is facilitated, and life safety of the passengers is protected.

    本发明公开了一种抗冲击夹层玻璃及制备工艺,包括第一玻璃层、第二玻璃层以及设置于第一玻璃层和第二玻璃层之间的复合中间层,复合中间层包括应力集中层、应力扩散层以及设置于应力集中层和应力扩散层之间的第三玻璃层;应力集中层、第三玻璃层与应力扩散层之间的厚度比为0.6~1:1:1~1.5;第二玻璃层作为车窗的外侧,在应力扩散层的辅助下具备卓越的抗冲击性能,而第一玻璃层作为车窗的内侧,在应力集中层的辅助下,能够从车内较易破碎整块夹层玻璃,在保证车辆安全性的同时,还保证在极端驾驶环境下,方便驾乘人员自救,保护乘客生命安全。
