Embodiment 1

[0024] S1 Put the raw materials of each component into the high mixer and blend for 30 minutes;

[0025] S2 Add the mixture obtained in S1 into a twin-screw extruder, the extrusion processing temperature is 200°C, and the screw speed is 280rpm;

[0026] S3 sends the cooled extrudate to the granulator to obtain high-performance wear-resistant plastic granules. Example 2

Embodiment 2

[0027] The difference from Example 1 is that the temperature in step S2 is 220° C., and the screw speed is 500 rpm. Example 3

Embodiment 3

[0028] The difference from Example 1 is that the temperature in step S2 is 260° C., and the screw speed is 600 rpm. performance test

[0029] The thermoplastic elastomer obtained in the above examples was subjected to thermoplastic molding, and after being made into a sample according to the requirements of relevant standards, a performance test was carried out, and the wear-resistant plastic disclosed in the patent CN01116594 was used as a control. The test data are shown in Table 2.

[0030] The performance test data of table 2 embodiment 1~embodiment 3 and comparative example

[0031]

Description

technical field [0001] The invention provides an engineering plastic, in particular relates to an engineering plastic with high wear resistance, and belongs to the technical field of polymer materials. Background technique [0002] Engineering plastics refer to a class of high-performance polymer materials that can be used as structural materials, withstand mechanical stress in a wide temperature range, and be used in harsh chemical and physical environments. Engineering plastics can withstand certain external forces, and have good mechanical properties and dimensional stability. They can still maintain their excellent properties at high and low temperatures, and can be used as plastics for engineering structural parts. At present, engineering plastics have been used in many fields of automobile industry, electronics industry, machinery manufacturing, medical treatment and daily life. [0003] With the development of industrial manufacturing level, higher requirements are p...
