Abstract:
1. A heat-resistant polyamide composition, which is characterized by comprising the following components in percentage by weight: 40% to 90% of heat-resisting polyamide resin, 5% to 35% of mineral fiber A, 14.2 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, wherein the heat-resistant polyamide resin comprises a dicarboxylic acid component unit a and a diamine component unit b, the dicarboxylic acid component a comprises aromatic dicarboxylic acids, and the content of the dicarboxylic acids component in the heat-resistant polyamide resin is more than 25 mol %; the diamine component b comprises a linear aliphatic diamine component with carbon numbers of 4 to 20 and/or an aliphatic diamine component with branched chain and/or an alicyclic diamine component; and the ratio of amine-terminated group and carboxyl-terminated group is controlled between 0.1 and 0.8.
