Abstract

The invention relates to a high glowing filament environmental-friendly inflaming retarding reinforced polybutylece terephthalate (PBT)/acrylonitrile butadiene styrene (ABS) alloy material. The material comprises the following components in percentage by weight: 22.5-41% of PBT, 22.5-41% of ABS, 6-20% of complexing inflaming retardant, 3-15% of antimonous oxide, 20-30% of glass fiber, 2-10% of flexibilizer, 0.1-1% of antioxidant and 0.1-1% of lubrication dispersing agent. The preparation method comprises the following steps: putting raw materials weighed based on the weight proportion into a high mixer, mixing for 2-5 minutes, and then discharging; and then extruding and granulating by using an extruding machine at the processing temperature of 230-240 DEG C at the screw rotating speed of 30-40Hz. Compared with the alloy material prepared by the prior art, the high glowing filament environment-friendly inflaming retarding reinforced PBT/ABS alloy material has the advantages of high glowing filament temperature, environmental friendliness, balanced comprehensive performance and the like.

Description

technical field [0001] The invention relates to a PBT / ABS alloy material, in particular to a high-glow wire environment-friendly flame-retardant reinforced PBT / ABS alloy material and a preparation method thereof. Background technique [0002] PBT is a milky white translucent to opaque, crystalline thermoplastic polyester. It has high heat resistance, toughness, fatigue resistance, self-lubrication, low friction coefficient, weather resistance, low water absorption, only 0.1%, and still maintains various physical properties (including electrical properties) and electrical insulation in a humid environment. Good formability. The disadvantage is that the notched impact strength is low and the molding shrinkage is large. Therefore, most of them are reinforced by glass fiber or modified by inorganic filling, the tensile strength and bending strength can be more than doubled, and the heat distortion temperature is also greatly increased. It can work at 140°C for a long time, an...
