Benefits of technology

[0045]In the following description, several exemplary examples are given to provide a thorough understanding of the deodorization and antistatic effects of the invention.

Problems solved by technology

If the content of the bamboo charcoal powder is increased beyond the range, the conductivity will be lowered since the content of the conductive carbon black powder is decreased correspondingly, which could fail to provide sufficient antistatic effect.

example 1

[0046]100 parts of the conductive carbon black powder were added into a mechanical granulating machine (commercial equipment AMS-LAB made by the HOSOKAWA company). The conductive carbon black powder was blended for about 5 minutes in the mechanical granulating machine with the operation parameters of 2.2 kW of power and 2480 rpm of rotation speed, to form the conductive powder composite of Example 1.

example 2

[0047]75 parts of the conductive carbon black powder and 25 parts of the bamboo charcoal powder were added into a mechanical granulating machine (commercial equipment AMS-LAB made by the HOSOKAWA company), respectively. The bamboo charcoal powder and the conductive carbon black powder were blended for about 5 minutes in the mechanical granulating machine with the operation parameters of 2.2 kW of power and 2480 rpm of rotation speed, to form the conductive powder composite of Example 2.

example 3

[0048]50 parts of the conductive carbon black powder and 50 parts of the bamboo charcoal powder were added into a mechanical granulating machine (commercial equipment AMS-LAB made by the HOSOKAWA company), respectively. The bamboo charcoal powder and the conductive carbon black powder were blended for about 5 minutes in the mechanical granulating machine with the operation parameters of 2.2 kW of power and 2480 rpm of rotation speed, to form the conductive powder composite of Example 3.

Abstract

The invention provides a conductive powder composite including a bamboo charcoal powder pre-processed with a pulverizing procedure and a refining procedure of 900 to 1500° C. and a conductive carbon black powder, wherein the bamboo charcoal powder and the conductive carbon black powder are blended by a high speed mechanical granulating machine to form the conductive powder composite. The conductive powder composite can simultaneously and effectively improve the poor conductivity of the bamboo charcoal powder and the embrittlement characteristic of the conductive carbon black powder in the conventional technology. The invention also provides a conductive masterbatch and a fabrication method thereof, and a multifunctional antistatic non-woven fabric and a fabrication method thereof.

Description

FIELD OF THE INVENTION[0001]The present invention relates generally to an antistatic non-woven fabric and the fabrication method thereof. More particularly, the present invention relates to a conductive powder composite containing a bamboo charcoal powder and a conductive carbon black powder, a conductive masterbatch fabricated from the conductive powder composite and a fabrication method thereof, and an antistatic non-woven fabric fabricated from the conductive masterbatch and a fabrication method thereof.BACKGROUND OF THE INVENTION[0002]In the electronic industry, protective clothing is used to separate human body from the clean room for production. As the wearer moves his or her arms and legs, electrostatic charge can be accumulated on the clothing. The accumulated electrostatic charge can be imparted to semiconductor devices, which would result in the electrostatic discharge (ESD) damage. Therefore, the protective clothing used should have antistatic effect or ESD protection eff...
