CN106380770A 一种阻燃苯乙烯类树脂组合物及其制备方法 无效 - 驳回

一种阻燃苯乙烯类树脂组合物及其制备方法
摘要：
本发明涉及一种阻燃苯乙烯类树脂组合物，所述组合物包括以下组分及重量份含量：苯乙烯类树脂85-90重量份；卤系阻燃剂4-6重量份；锑系阻燃剂1-2重量份；磷系阻燃剂3-5重量份；抗氧剂0.1-0.2重量份，冲击改性剂0-2.0重量份。本发明在卤素、锑系、磷系阻燃剂的协同作用下，有效提高了苯乙烯类树脂的阻燃效率，提高了苯乙烯类树脂的流动性和表观质量，从而解决了阻燃苯乙烯类树脂注塑成型困难和光泽度低的问题，具有广阔的应用前景。
摘要（英）：

The present invention relates to a flame-retardant styrene resin composition, which comprises the following components in weight part: 85-90 parts of styrene resin, 4-6 parts of halogen-based flame retardant, 1-2 parts of antimony-based flame retardant, 3-5 parts of phosphorus-based flame retardant, 0.1-0.2 part of antioxidant, and 0-2.0 parts of impact modifier. According to the technical scheme of the invention, under the synergistic effects of the antimony-based flame retardant, the phosphorus-based flame retardant and the halogen-based flame retardant, the flame-retardant efficiency of styrene resin is effectively improved. The flowability and the apparent quality of styrene resin are improved. Therefore, the problems in the prior art that styrene resin is difficult in injection molding and low in gloss can be solved. As a result, the flame-retardant styrene resin composition has a wide application prospect.
