Embodiment Construction
[0020] The present invention will be further described below in conjunction with specific embodiments.
[0021] The technical solution of this embodiment is: a low-fiber flame-retardant reinforced PBT composite material, which is composed of the following components in mass percentage: PBT 55%~70%, toughening agent 5-15%, silane coupling agent 0.2 %~0.5%, chopped glass fiber 10%-20%, environmentally friendly flame retardant 10~15%, antioxidant 0.1%~0.5%, lubricant 0.1%~1%, floating fiber remover 0.3%~0.8% .
[0022] Wherein, the toughening agent adopts PBT-containing crystalline hard segment or polyester soft segment type.
[0023] Wherein, the toughening agent is a thermoplastic polyester elastomer.
[0024] Wherein, the environmentally friendly flame retardant uses decabromodiphenylethane and / or antimony trioxide.
[0025] Wherein, the lubricant adopts a mixture of fatty acid ester and ethylene bisstearamide, and the weight ratio of the two is 1-2:1.
[0026] Wherein, the floating fi...
