Abstract: Disclosed is a flame-retardant HIPS material and a preparation method thereof, comprising the following components: 90 parts to 67 parts of a HIPS resin; 8 parts to 15 parts of a brominated flame retardant; and 3 parts to 7 parts of an auxiliary flame retardant; wherein the auxiliary flame retardant is a 1,3,5-triazine compound. In the present invention, a synergistic compounding of the brominated flame retardant and the auxiliary flame retardant effectively reduces an amount of the brominated flame retardant, and a stable UL 94 (1.5 mm) V-0 flame-retardant class can be achieved. Compared with the existing brominated flame-retardant HIPS, the present invention has a low halogen content, low gas, and high cost performance ratio, which avoids excessive acid gas from forming air lines on the surface of parts, has a good appearance.

Abstract: 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 15-100 parts of a toughening agent, 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 10-45% of the total weight part of the toughening agent. The polyacrylate polymer composite material has the advantages of high transparency and high toughening efficiency, and a prepared film cannot be broken and has no white folding marks after being repeatedly folded in half.

Abstract: Disclosed is a flame-retardant HIPS material and a preparation method thereof, comprising the following components: 79 parts to 91 parts of a HIPS resin; 2 parts to 8 parts of a brominated flame retardant; and 3 parts to 7 parts of an auxiliary flame retardant; wherein the auxiliary flame retardant is a 1,3,5-triazine compound. In the present invention, a synergistic compounding of the brominated flame retardant and the auxiliary flame retardant effectively reduces an amount of the brominated flame retardant, and a stable UL 94 (1.5 mm) V-2 flame-retardant class can be achieved. Compared with the existing brominated flame-retardant HIPS, the present invention has a low halogen content, low gas, high cost performance ratio, relatively good thermal stability, and relatively light corrosiveness to the mold, and can be widely applied in the field of thin-walled parts, such as office equipment, video multimedia, household appliances and the like.
