High-luster low-warpage glass fiber reinforced PBT/PP (Polybutylene Terephthalate/Polypropylene) alloy and preparation method thereof

摘要: The invention relates to a high-luster low-warpage glass fiber reinforced PBT/PP (Polybutylene Terephthalate/Polypropylene) alloy and preparation method thereof. is prepared from the following ingredients raw materials in parts by weight: 45-65 of PBT, 10-30 PP, 20-30 fibers, 1-5 compatibilizer, polyvinyl butyral, 1-4 surface-finishing agent, 0.5-1 part lubricant 0.2-1 an antioxidant. comprises steps putting other ingredients, except for into high-speed mixer, mixing uniformly at room temperature, then, feeding mixture twin-screw extruder, adding fibers fourth temperature region carrying out melting, blending extruding, drawing, water-cooling, drying pelleting, thereby obtaining alloy. Compared with prior art, thereof have advantages that due adoption butyral tackifying effect, viscosity PBT effectively improved, crystallization resin inhibited, warpage improved.
