Embodiment 1
[0050] A high-efficiency flame-retardant polycarbonate material is made of the following raw materials in parts by mass,
[0051] PC resin 100 parts
[0052] Sulfonate flame retardant 0.02-0.2 part,
[0053] Fill 1-9 parts of mineral powder,
[0054] 0.5-4 parts of silicon-based toughening agent,
[0055] Anti-hydrolysis agent 0.5-4 parts,
[0056] Lubricant 0.1-0.5 parts,
[0057] Anti-dripping agent 0.05-1 part,
[0058] 0.3-1 part of antibacterial agent,
[0059] Antioxidant 0.2-0.6 part.
[0060] PC resin can be selected according to actual needs, and its fluidity is 9-25g / 10min. The PC resin here is PC-1020 produced by Zhetie Dafeng Chemical Industry Co., Ltd., which is isosorbide polycarbonate, and its MFR=10g / 10min.
[0061] The sulfonate flame retardant is one of potassium perfluorobutane sulfonate (KFBS), potassium diphenyl sulfone sulfonate (KSS) or sodium trichlorobenzene sulfonate (STB) or a combination of two. Potassium perfluorobutanesulfonate (KFBS), po...
