The present invention provides a polyacrylate polymer composite material, characterized by comprising the following components in parts by weight: 100 parts of a polyacrylate polymer, and 15 to 100 parts of toughening agents, wherein the toughening agent is selected from a compounding of a two-layer core-shell structure toughening agent and a three-layer core-shell structure toughening agent, and the two-layer core-shell structure toughening agent accounts for 10% to 45% of a total weight of the toughening agents. The polyacrylate polymer composite material has advantages of high transparency and high toughening efficiency, without fracture or folding-induced whitening marks when it is prepared into a film and repeatedly folded in half.
