Embodiment 5

[0026] In Example 5: the selected nylon elastomer is PEBAX 5533SP01 produced by Arkema, France, the permanent antistatic agent is PEBAX MV2080 produced by Arkema, France, and the remaining components are the same as in Example 1.

Embodiment 6

[0027] In Example 6: the selected nylon elastomer is PEBAX 5533SP01 produced by Arkema, France, the permanent antistatic agent is PEBAX MH2030 produced by Arkema, France, and the remaining components are the same as in Example 1.

[0028] Its preparation method: in parts by weight, weigh each raw material and dry at 65°C-95°C for 3-6 hours, add to a high-speed mixer and mix for 20 minutes, then extrude and granulate in a twin-screw extruder. The aspect ratio of the twin-screw extruder is 40:1, the temperature of the screw barrel is controlled at 160-220°C, and the screw speed is at 250-500 rpm.

Abstract

The invention discloses a permanent antistatic nylon elastomer material and a preparation method thereof. The permanent antistatic nylon elastomer material comprises the following ingredients in parts by weight: 50-90 parts of nylon elastomer, 10-30 parts of permanent antistat and 0.3-2 parts of processing agent. The method comprises the following steps that: the ingredients are put in a high-speed mixer according to the ratio and mixed evenly; and the mixture is fed into a double-screw extruder and the nylon elastomer material is obtained after mixing, extruding, pulling, cooling and palletizing. The antiflaming permanent antistatic nylon elastomer material prepared by the invention has excellent impact property and the surface resistance is 107-1010W, and thus the permanent antistatic nylon elastomer material is applicable to components with the requirements on static resistance and dust prevention in the field of electric products, automobile body devices, mechanical engineering, sanitary equipment and the like.

Description

technical field [0001] The invention belongs to the technical field of functional polymer materials, and in particular relates to a permanent antistatic nylon elastomer material and a preparation method thereof. Background technique [0002] The preparation of permanent antistatic materials is generally to add conductive fillers or polymer permanent antistatic agents to the polymer matrix for compounding. Commonly used conductive fillers include conductive carbon black, carbon fiber, graphite, whiskers, metal fibers, etc. The problems often encountered in the preparation of antistatic materials by adding conductive fillers are uneven dispersion of fillers and surface defects. With the development of permanent polymer antistatic agents and their promotion in the market, adding permanent polymer antistatic agents has become one of the important methods for preparing permanent antistatic materials. Its conductive mechanism can be summarized as the combination of oxygen-contai...
