The invention discloses a thermal shock resistant metallized film and a preparation method thereof, the thermal shock resistant metallized film is composed of a base film and a metal film, and the base film comprises the following components: polypropylene resin, polytetrafluoroethylene, glass fiber, nano pottery clay, a flame retardant synergist, an anti-aging agent, a cross-linking agent and a lubricant. The nano-clay is modified, so that the uniform dispersion of the nano-clay in a polypropylene matrix is improved, the crosslinking of the nano-clay and polypropylene resin is promoted, the molecular structure of the polypropylene film matrix is greatly improved, the rigidity of a polypropylene molecular chain is increased, and the high-temperature impact resistance of the nano-clay is greatly improved. 本发明公开了一种耐热冲击的金属化薄膜及其制备方法，所述耐热冲击的金属化薄膜由基膜和金属膜组成，所述基膜包括如下组分：聚丙烯树脂、聚四氟乙烯、玻璃纤维、纳米陶土、阻燃协效剂、防老剂、交联剂、润滑剂。通过对纳米陶土进行改性，改善了其在聚丙烯基体中的均匀分散，促进其与聚丙烯树脂的交联，极大了改善了聚丙烯薄膜基体的分子结构，增加了聚丙烯分子链的刚性，极大提高了其耐高温冲击能力。
