一种低模垢无卤阻燃热塑性聚酰胺组合物及其制备方法和应用
摘要：
本发明提供一种低模垢无卤阻燃热塑性聚酰胺组合物及其制备方法和应用。本发明的低模垢无卤阻燃热塑性聚酰胺组合物，包括如下按重量份计算的组分：20～82份热塑性聚酰胺树脂；13～25份阻燃剂；1～5份阻燃协效剂；5～50份增强材料；0.5～5份吸附剂；其中，所述阻燃剂包括次膦酸盐类阻燃剂；所述吸附剂为乙烯共聚物。本发明的低模垢无卤燃热塑性聚酰胺组合物，加入乙烯共聚物作为吸附剂，并通过控制其加入量，制备得到的低模垢无卤燃热塑性聚酰胺组合物，不仅具有优异的阻燃性能和电性能，而且能够有效降低注塑过程中小分子物的释放量，大幅度减少注塑过程产生的模垢量。
摘要（英）：

The present invention provides a low-mold deposit halogen-free flame-retardant thermoplastic polyamide composition, and a preparation method therefor and an application thereof. The low-mold deposit halogen-free flame-retardant thermoplastic polyamide composition of the present invention comprises the following components in parts by weight: 20-82 parts of a thermoplastic polyamide resin; 13-25 parts of a flame retardant; 1-5 parts of a flame retardant synergist; 5-50 parts of a reinforcing material; and 0.5-5 parts of an adsorbent. The flame retardant comprises a phosphinate flame retardant, and the adsorbent is an ethylene copolymer. According to the low-mold deposit halogen-free flame-retardant thermoplastic polyamide composition of the present invention, the ethylene copolymer is added as the adsorbent, and the amount of addition thereof is controlled, so that the prepared low-mold deposit halogen-free flame-retardant thermoplastic polyamide composition has excellent flame retardancy and electrical properties, and can effectively reduce the release amount of small molecules in the injection molding process, thereby greatly reducing the mold deposit in the injection molding process.
