20080293861 | Composition of high impact glass fiber reinforced engineering plastic and preparation method thereof - A composition of a high impact glass fiber reinforced engineering plastic and a preparation method thereof, including except for glass fiber, from 30% to 70% by weight of a polyamide6 (PA6), from 15% to 25% by weight of an acrylonitrile-butadiene-styrene copolymer (ABS), from 4% to 6% by weight of a compatilizer, from 0.3% to 0.5% by weight of an antioxidant, and from 0.3% to 0.6% by weight of a lubricant are firstly added into a high-speed mixer and then mixed for 2-5 min. The blend composition is fed into a twin screw extruder, and from 10% to 30% by weight of a glass fiber is added into the twin screw extruder at the second half stage, and ground together to be granulated and molded. During the preparation, the process temperature is from 180° C. to 245° C., the screw rotating speed is from 240 rpm to 560 rpm. | 11-27-2008 |
20080290331 | Composition of glass fiber reinforced flame-retardant engineering plastic and preparation method thereof - A composition of a glass fiber reinforced engineering plastic and a preparation method thereof are provided. The method includes: except for glass fiber, from 30% to 70% by weight of a polyamide6, from 8% to 30% by weight of an acrylonitrile-butadiene-styrene copolymer, from 3% to 6% by weight of a compatilizer, from 12% to 16% by weight of a flame retardant, from 0.3% to 0.5% by weight of an antioxidant, and from 0.3% to 0.8% by weight of a lubricant are added into a high-speed mixer, and then mixed for 2-5 min. The blend composition is fed into a twin screw extruder, and from 18% to 35% by weight of a glass fiber are added into the twin screw extruder at the second half stage, and ground together to be granulated and molded. | 11-27-2008 |
20080290330 | Composition of high impact glass firber reinforced flame-retardant engineering plastic and preparation method thereof - A composition of a high impact glass fiber reinforced flame-retardant engineering plastic and a method thereof, which the method includes except for glass fiber, from 30% to 60% by weight of a polyamide 6, from 8% to 25% by weight of an acrylonitrile-butadiene-styrene copolymer, from 3% to 6% by weight of a compatilizer, from 4% to 10% by weight of a flexibilizer, from 12% to 16% by weight of a flame retardant, from 0.3% to 0.5% by weight of an antioxidant, and from 0.3% to 0.8% by weight of a lubricant are added into a high-speed mixer, and mixed for 2-5 min, and the blend composition is fed into a twin screw extruder, and from 18% to 30% by weight of a glass fiber are added into the twin screw extruder at the second half stage, and ground together to be granulated and molded. | 11-27-2008 |
