Problems solved by technology

[0003] However, continuous long aluminum fiber reinforced PPO materials are still a relatively cutting-edge research field in China. At present, there are few studies in this area. The main reason is that some domestic companies have not solved the problem of compatibility between PPO and aluminum fibers.

Embodiment 1

[0019] The continuous long aluminum fiber reinforced PPO compound of the present embodiment comprises each component of weight percentage content as shown in Table 1; During preparation, weigh raw material by the weight proportion shown in Table 1 and put into high mixer and mix 2 ~5 minutes, discharge the material, and then use a twin-screw extruder to extrude and granulate. The specific steps are as follows:

[0020] Step 1: Add PPO, compatibilizer, antioxidant, and molecular weight regulator into the twin-screw extruder in proportion, and after being plasticized by the twin-screw extruder, transport it to the high-temperature melt-infiltrating die head. In the melt infiltration tank, the temperature in the high temperature melt infiltration die head is 280-330°C, the length of the high-temperature melt infiltration tank is 6m, and the temperature of the twin-screw extruder is 260-280°C;

[0021] Step 2: Pull the continuous long aluminum fiber into the high-temperature melt ...

Embodiment 2

Abstract

The invention discloses a continuous long aluminum fiber reinforced PPO composite and a preparation method thereof. The composite comprises the following components in percentage by weight: 45-70% of PPO, 20-42% of continuous long aluminum fiber, 4-10% of compatibilizing agent, 0.5-1.5% of antioxidant and 0.5-1.5% of molecular weight regulator. The preparation method comprises the following steps: adding the PPO, the compatibilizing agent, the antioxidant and the molecular weight regulator into a double screw extruder, plastifying, and delivering into a high-temperature molten mass wetting tank in a high-temperature molten mass wetting die head, wherein the temperature in the die head is 280-330 DEG C, and the temperature of the extruder is 270-290 DEG C; and drawing the continuous long aluminum fiber into the wetting tank at a rate of 20-100 m / min, sufficiently wetting, cooling, and granulating. The composite product disclosed by the invention is high in average fiber length, and the long fiber forms a network structure in an injection molded product, so that the product has mechanical properties and other physical properties which are superior to those of a chopped fiber reinforced composite material.

Description

technical field [0001] The invention relates to an aluminum fiber reinforced PPO composite, in particular to a continuous long aluminum fiber reinforced PPO composite and a preparation method thereof. Background technique [0002] At present, at home and abroad, the fibers used for PPO material reinforcement include glass fiber, carbon fiber, aluminum fiber, stainless steel fiber and so on. Fiber-reinforced PPO materials can be divided into two types of reinforcement: chopped fiber reinforcement and continuous long fiber reinforcement. Compared with traditional chopped fiber reinforced pellets, long fiber reinforced thermoplastic composites (LFRTP) have higher comprehensive properties. Continuous long aluminum fiber reinforced PPO composites can be used in many fields of industry and civil use, including automobiles, equipment, entertainment, food processing, communications, electrical and electronic, power tools, gardening, etc. Automotive applications account for 80 perc...
