Problems solved by technology

But at the same time, there are also the following disadvantages: ①The fluidity is too high at high temperature, and it is difficult to inject resin alone; ②The cost is high, and the price is twice as high as that of general engineering plastics; ③The impact strength is poor, the product is brittle, and the welding strength is not good. Good; ④ Due to its excellent chemical resistance, its coating and coloring properties are not ideal, so it is necessary to modify
However, the above-mentioned patent does not add a toughening agent, and the impact strength of the resulting PPS/PEEK alloy is limited. If it is used in safety-related fields, such as battery packs for electric vehicles, poor impact strength will easily lead to cracking of the battery pack after impact, electrolysis Liquid lea

Embodiment 1

[0025] Example 1: SEBS filled with 1Kg polyphenylene sulfide, 99Kg polyether ether ketone, 50Kg iron powder, 3Kg compatibilizer M3002, 5Kg silicone oil (the mass fraction of silicone oil is 5%), 0.2Kg aluminate coupling agent , 0.1Kg antioxidant N412S, 0.1Kg antioxidant N445, and 0.5Kg OP-180 were added to a high-speed mixer and mixed evenly at a high speed, and then 10Kg chopped glass fiber was added and mixed evenly at a low speed to obtain a mixed material. Then the mixed materials are melted, kneaded, extruded, cooled, dried, pelletized into pellets through a twin-screw extruder and then injected into products. Among them, the temperature of each zone of the twin-screw extruder and the screw barrel of the injection molding machine should be kept between 240ˉ310°C.

Embodiment 2

[0026] Example 2: SEB-g-MAH filled with 99Kg polyphenylene sulfide, 1Kg polyether ether ketone, 1Kg silicon carbide, 10KgHIPS, 30Kg fluorine oil (the mass fraction of fluorine oil is 50%), and 2Kg titanate coupling Agent NDZ-101, 1Kg antioxidant 1010, 1Kg antioxidant 168, and 3Kg calcium stearate were added to a high-speed mixer and mixed evenly at high speed, and then 200Kg chopped glass fiber was added and mixed evenly at a low speed to obtain a mixed material. Then the mixed material is melted, kneaded, extruded, cooled, dried, pelletized into pellets by a twin-screw extruder and then injected into products. Among them, the temperature of each partition of the twin-screw extruder and the screw barrel of the injection molding machine should be kept between 240-310°C.

Embodiment 3

[0027] Example 3: 60Kg polyphenylene sulfide, 40Kg polyether ether ketone, 30Kg graphite, 4KgPEEK-g-MAH, 20Kg silicone oil filled SEBS-g-MAH (silicone oil mass fraction is 25%), 2Kg aluminate Joint agent, 0.4Kg N412S, 0.4Kg antioxidant N445, 1Kg stearic acid, 0.5Kg light stabilizer were added to the high-speed mixer and mixed evenly at high speed, and then 80Kg chopped glass fiber was added and mixed evenly at low speed to obtain a mixed material. Then the mixed material is melted, kneaded, extruded, cooled, dried, pelletized into pellets by a twin-screw extruder and then injected into products. Among them, the temperature of each partition of the twin-screw extruder and the screw barrel of the injection molding machine should be kept between 240ˉ310°C.
