Problems solved by technology

[0002] At present, flame-retardant reinforced PA66 or PA6 with high glow wire temperature is used in electronic components used in unattended white goods, and there is generally insufficient toughness at low temperature (≤-30°C), and it is easy to crack and become brittle.
Therefore, the current technical formula of flame retardant reinforced PA66 or PA6 with high glow wire temperature cannot meet the material performance requirements of electronic components used in unattended white goods in low temperature (≤-30°C) working environment

Abstract

The invention relates to the field of modified engineering plastics, in particular to a flame retardant reinforced co-polymerized nylon composite with high temperature of glowing filaments and a preparation technology thereof. The composite comprises the following ingredients: 48.7-69.6 wt% of PA66 / 6, 14.5-18.6wt% of polybrominated styrene, 4.3-5.5wt% of diantimony trioxide, 1.7-2.2wt% of layereddihydroxy composite metallic oxide, 0.08-0.11wt% of teflon and 10-30wt% of alkali free glass fiber. Compared with the prior art, the composite has the advantages that: the glowing filament ignition temperature GWIT is not less than 775 DEG C, the flame resistance that in accordance with 94UL-V0 standard is rated V-0 at 0.8 mm to 1.6 mm, and the composite meets VDE standard, has good low-temperature (less or equal to -30 DEG C)toughness, and satisfies the requirements of electronic components used in unattended white goods working in low-temperature (less or equal to -30 DEG C) environment to material qualities.

Description

[Technical field] [0001] The invention relates to the field of modified engineering plastics, in particular to a flame-retardant reinforced copolymerized nylon composite material with high glow wire temperature and its technology. [Background technique] [0002] At present, flame-retardant reinforced PA66 or PA6 with high glow wire temperature is used in electronic components used in unattended white goods, and there is generally insufficient toughness at low temperature (≤-30°C), and it is easy to crack and become brittle. . Therefore, the current technical formula of flame retardant reinforced PA66 or PA6 with high glow wire temperature cannot meet the material performance requirements of electronic components used in unattended white goods in low temperature (≤-30°C) working environment. [Content of the Invention] [0003] The object of the present invention is to aim at the above-mentioned deficiencies, and design a flame-retardant reinforced copolymerized PA66 / 6 comp...
