Embodiment

[0020] Embodiment: the product performance test of the composite material prepared by the present invention

[0021] 1. Composite material preparation

[0022] (1) Preparation of PPO / PA composite material A

[0023] Raw materials: 90 parts of PPO resin, 10 parts of PA6I resin, 0.2 parts of antioxidant, 2 parts of lubricant. (The mass ratio of PPO and PA6I is 9:1)

[0024] 1. Weigh 45 kg of PPO resin, 5 kg of dried PA6I resin, 0.1 kg of antioxidant, and 1 kg of lubricant, add them to a 500L-SHR high-speed mixer, mix at low speed for 1 minute, then mix at high speed for 2 minutes, and release materials;

[0025] 2. Feed the mixed material into the TE-35 twin-screw extruder, and after the material comes out of the extruder die, it will be cooled, blown dry, and pelletized to obtain the PPO / PA composite material .

[0026] The temperature of each zone of the twin-screw extruder is set as follows: the temperature in the first zone is 180-185°C, the temperature in the second zo...

Abstract

The invention discloses a PPO/PA (poly phenylene oxide-polyamide) composite material and a preparation method thereof. The product is prepared by performing melt blending on PPO and semi-aromatic PA6I. Since molecular structures of the two components have benzene ring structures, organic compatibility among molecules can be achieved, and a compatibility problem is solved without an additional compatilizer. Meanwhile, the PA6I is low in melting temperature and excellent in transparency, and after the PA6I of a certain ratio is added into the PPO, the transparency and processing fluidity of thePPO can be improved. Compared with the conventional PPO/PA having basically equivalent product properties such as tensile strength, bending strength, impact strength, processing fluidity, heat resistance and the like, the PPO/PA composite material disclosed by the invention has the advantages that any compatilizer is not needed, the prepared product has excellent transparency, products with transparency requirements can be prepared, but the PPO/PA composite material disclosed by the invention is completely opaque.

Description

technical field [0001] The invention relates to a PPO / PA composite material and a preparation method thereof, and relates to the field of polymer materials. Background technique [0002] Polyphenylene ether (PPO) has the advantages of excellent mechanical properties, heat resistance, electrical insulation, low water absorption, dimensional stability, creep resistance, etc., but pure PPO resin has a high glass transition temperature and poor melt fluidity , It is difficult to form and process, and it needs to be processed at a high temperature of 300 ° C, which greatly limits its application. [0003] Polyamide (PA) has the advantages of wear resistance, self-lubrication, easy processing, solvent resistance, and high mechanical strength, but it has relatively large water absorption, poor heat resistance, and large changes in product size after water absorption. [0004] Blending PPO and PA to prepare an alloy can combine the advantages of the two and expand the application f...
