    摘要: 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.

    摘要: The present disclosure discloses a halogen-free flame-retardant polyamide (PA) composite, including the following components in parts by weight: 20 to 50 parts of an aliphatic PA, 10 to 30 parts of an aromatic PA, 20 to 30 parts of a halogen-free flame retardant, 10 to 50 parts of a glass fiber, 1 to 5 parts of a char-forming agent, and 0 to 5 parts of an additive, where the aromatic PA is at least one selected from the group consisting of PA66/6T, PA MXD6, and PA6T/6I and the char-forming agent is at least one selected from the group consisting of dipentaerythritol (DPE) and tripentaerythritol (TPE). In the halogen-free flame-retardant PA composite of the present disclosure, the aromatic PA itself has high-temperature resistance and aging resistance and exhibits a synergistic effect with a dense carbon layer formed by the char-forming agent during aging, such that the halogen-free flame-retardant PA composite has excellent weather resistance, aging resistance, and flame retardation. In addition, the present disclosure discloses a preparation method of the halogen-free flame-retardant PA composite.
