    摘要: The present invention discloses a furan diacid-based polyamide, which is derived from the following repeating units: (A) 2,5-furandicarboxylic acid, (B) 1,4-cyclohexanedicarboxylic acid, and (C) 1,5-pentanediamine, where based on the total molar percentage of the diacid units, (A) accounts for 10-45 mol% of the diacid units. On one hand, by selecting a bio-based 2,5-furandicarboxylic acid, the furan diacid-based polyamide of the present invention is more environmentally friendly, and has the advantages of a melting point of 291-335°C and lower water absorption (a water absorption rate than that of a polyamide with the same amido bond density) ; on the other hand, the rigidity of cyclohexane is higher than that of an aromatic ring, such that more hard carbon layers can be formed during combustion. In addition, the furan diacid-based polyamide has a relatively high amido bond density, and can generate a relatively excellent synergistic effect with a flame retardant, such that the flame retardant effect is excellent under the synergistic effect of the two.

    摘要: Disclosed are a halogen-free fire-retardant polyamide composition, and a preparation method and application thereof. The halogen-free fire-retardant polyamide composition is prepared from 35 to 71.5% of a semi-aromatic polyamide, 10 to 35% of a fire retardant and 0 to 50% of an inorganic reinforcing filler, the terminal amino group content of the semi-aromatic polyamide being 80 to 150 mol/t. The halogen-free fire-retardant polyamide composition of the present invention has good heat stability and releases only a small amount of gas in production; mold dirt is not easily formed, and the halogen-free fire-retardant polyamide composition can be produced continuously.

    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.
