    摘要： The present invention discloses a heat-resistant polyamide composition and application thereof. The composition comprises the following components in percentage by weight: 40% to 90% of heat-resistant polyamide resin, 5% to 35% of mineral fiber A, 0 to 35% of mineral filler B, 0.1% to 1% of light stabilizer, 0.1% to 1% of flow modifier and 0.1% to 1% of antioxidant. In the present invention, heat-resistant polyamide resin with the ratio of amine-terminated group and carboxyl-terminated group between 0.1 and 0.8 is selected to be matched with deformed glass fibers with an aspect ratio of 2 to 6, the mineral filler B and the flow modifier to obtain the heat-resistant polyamide composition. The heat-resistant polyamide composition not only has high initial whiteness, high reflectivity and excellent heat resistance, but also has good moldability and good dimensional stability; therefore, the heat-resistant polyamide composition is capable of being applied for preparing the reflecting supports for such light sources as LCD backlight of portable phones, computers, televisions and the like, as well as headlights of automotive vehicles, instrument panels and lighting appliances, etc.

    摘要翻译： 本发明公开了耐热性聚酰胺组合物及其应用。 该组合物包含以下重量百分比的组分：40％至90％的耐热聚酰胺树脂，5％至35％的矿物纤维A，0至35％的矿物填料B，0.1％至1％的光稳定剂 ，0.1％〜1％的流动改性剂和0.1％〜1％的抗氧化剂。 在本发明中，选择具有0.1〜0.8的胺封端基和羧基封端基的比例的耐热聚酰胺树脂与长宽比为2〜6的变形玻璃纤维匹配，矿物填料B和 流动改性剂以获得耐热聚酰胺组合物。 耐热性聚酰胺组合物不仅具有高的初始白度，高反射率和优异的耐热性，而且具有良好的成型性和良好的尺寸稳定性; 因此，耐热性聚酰胺组合物能够用于准备用于诸如便携式电话，计算机，电视机等的LCD背光源的这种光源的反射支撑，以及汽车，仪表板和照明器具的前灯， 等等
