The present invention relates to an impact-resistant film and laminated glass having the same; the glass-transition temperature of the impact-resistant film is increased along with increase of the strain rate of the impact-resistant film, and when the strain rate of the impact-resistant film is smaller than 10 <-3 > s <-1 >, the glass-transition temperature of the impact-resistant film is smallerthan the environment temperature; and when the strain rate of the impact-resistant film is greater than or equal to 103 s <-1 >, the glass transition temperature of the impact-resistant film is greater than or equal to the environment temperature. When the impact-resistant film is subjected to large external impact, the impact-resistant film can absorb energy generated by the external impact by being converted from a rubber state or a leather-like state into a glass state, so that the probability of glass breakage can be reduced.
本发明涉及一种抗冲击膜以及具有该抗冲击膜的夹层玻璃。所述抗冲击膜的玻璃化转变温度随着所述抗冲击膜的应变率升高而升高,其中,当所述抗冲击膜的应变率小于10s时,所述抗冲击膜的玻璃化转变温度小于环境温度;以及当所述抗冲击膜的应变率大于或等于10s时,所述抗冲击膜的玻璃化转变温度大于或等于环境温度。本发明的抗冲击膜在受到较大外来冲击时,通过从橡胶态或似革态转化为玻璃态,可以吸收外来冲击产生的能量,从而可以降低玻璃破碎的几率。
