Embodiment 1

[0050] 1-1. Hybrid carbon nanotubes (multiple walls with a length of 30? and a width of 10nm) 2% by weight, acrylic copolymer binder (Carboset CR780, BFGoodrich Co.) 15% by weight, isopropanol 50% by weight, Water 32% by weight, fluidity improver (HPA-538, Yeungsan Co.) 1% by weight, to produce thermosetting antistatic coating liquid.

[0051] 1-2. If figure 1 As shown, when the ABS resin is extruded through the T-die extrusion process (the temperature of the extruder is 150 ~ 170°C), the TPU / The antistatic coating solution used in the ABS hybrid antistatic mat is coated with a thickness of 0.3 ? 0.3? Thick coating on the reverse side and heat hardening and coating at 60-80 ℃ temperature, and finally produce an anti-static mat with anti-static coating layers on both sides. Surface resistance passed ASTM D257 method, both sides are 10E6 Ω / ?

Embodiment 2

[0053] The antistatic mat manufactured in the embodiment 1 was vacuum formed at a temperature of 150-180° C. to manufacture an antistatic tray extended 5 times.

Embodiment 3

[0055] Except that instead of the carbon nanotubes in Example 1-1, the conductive polymer [(polyethylene diauxy thiophene)] PEDOT is used, and after the antistatic coating liquid is produced in the same way, the same method as in Example 1-2 is used to produce the antistatic pad. The surface resistance passes the ASTM D257 method, and both sides are 10E6 Ω / ?.

Abstract

The invention relates to an antistatic pad and an antistatic tray as well as a manufacturing method thereof, and particularly relates to an antistatic pad and an antistatic tray which respectively comprise a thermal plastic elastomer and are favorable in abrasion resistance and shock resistance, and a manufacturing method for manufacturing the antistatic pad and tray. The method is characterized in that in the process of manufacturing the antistatic pad after the insulator thermoplastic macromolecule resin is extruded, through a one-step technology, a layer of thermal plastic elastomer (TPE) such as thermoplastic polyurethane (TPU) is formed on one surface of the antistatic pad; at the stage of forming antistatic coating layer by utilizing an antistatic coating liquid, the antistatic pad is manufactured through a one-step (in-line) technology. The manufacturing method of the antistatic pad, which is provided by the invention, can enable the production process of the antistatic pad with favorable abrasion resistance and shock resistance to keep excellent production efficiency; the antistatic pad manufactured by utilizing the method can be used for manufacturing an antistatic tray which is better in abrasion resistance and molding effect and is used for electronic fitting vacuum molding, antistatic products and the like.

Description

technical field [0001] The present invention relates to an antistatic mat, a tray and a manufacturing method thereof, in particular to an antistatic mat tray including a thermoplastic elastomer with good wear resistance and impact resistance, and a manufacturing method for producing them with high performance. Background technique [0002] Generally, the anti-static mat is coated with a layer of anti-static material on the surface of the insulator, that is, the base plastic, and then dried by thermal hardening or light hardening. The thermosetting coating method is to use various coating methods such as gravure coating, roll coating, rod coating, spray coating, etc. on the surface of the base plastic to manufacture antistatic tape or antistatic mat. This production method not only improves the production efficiency, but also can adjust the surface resistance, and the liquid stability is better. However, there are problems such as a decrease in bonding force, solvent resista...
