Embodiment 1-5 and comparative example 1-3

[0050] Components and proportioning of table 1 embodiment 1-5 and comparative example 1-3

[0051]

[0052] Preparation method: Weigh the raw materials according to the ratio in Table 1, mix the raw material components in a high-speed mixer for 3-5 minutes, and then extrude, cool, and granulate through a twin-screw extruder at 220-240°C. After the material is dried at 100°C for 4 hours, it is injection molded into a standard sample at 240-260°C.

[0058] The performance test results in Table 2 show that:

[0059] (1) In comparative examples 1, 2, and 3, POE-MAH toughened and modified PA / POK alloy was used alone. Although the impact performance was better, the strength and temperature resistance decreased greatly. This is because POE is a thermoplastic elastomer , more addition will affect the rigidity and temperature resistance of the material. And the use of GMA epoxy toughen...

Abstract

The present invention relates to the field of polymer materials, particularly to a POK-PA alloy material with characteristics of high wear resistance, static electricity resistance and low warpage, wherein the POK-PA alloy material comprises, by weight, 200-400 parts of POK, 200-500 parts of PA6, 10-100 parts of a compatible impact modifier, 10-30 parts of a toughening agent NG7002, 100-200 parts of electric conduction carbon black, 10-100 parts of a filler, 10-30 parts of PTFE, and 1-10 parts of an auxiliary agent. The invention provides the POK-PA alloy material with characteristics of high wear resistance, static electricity resistance and low warpage, wherein the material has good static electricity resistance (109 ohm), the wear coefficient of the material is 2.1 mm<3> / kg / km, the impact strength is good, the 23 DEG C impact strength can achieve 150 J / M, the -30 DEG C impact strength can achieve 100 J / M, and the balanced water absorption is significantly reduced and achieves 0.5%.

Description

technical field [0001] The invention relates to the field of polymer composite materials, in particular to a POK-PA alloy material with high wear resistance, antistatic and low warpage and a preparation method thereof. Background technique [0002] Polyamide (PA6) has the characteristics of thermoplasticity, light weight, excellent mechanical properties, chemical resistance and good durability. It is used in printers, banknote printing machines, ticket issuing machines, etc., which require paper feeding operation panels to replace metal parts. , to meet the requirements of light weight and cost reduction. In addition to ensuring high strength, it is also necessary to have good antistatic properties, so that the charges generated by friction between paper and paper and parts can be eliminated in time, and because of the continuous friction between paper and parts, the parts will be damaged. Wear resistance also puts forward certain requirements. However, ordinary PA6 has hi...
