Problems solved by technology

However, in the case of conductive additives such as carbon black, unless a considerable amount is added, it is difficult to sufficiently ensure the conductivity of the semiconductive resin to a desired level. In order to ensure the uniformity of surface resistance, a large amount of dispersant must be included. But this situation may eventually reduce the heat resistance and durability of the belt

Embodiment 1

[0046] Mix 1480g of DMF and 1.96g of carbon nanotubes (nanocarbon company, specifications Powder Dual structure CNT 50 multi-walled carbon nanotubes) and 1.96g of DMF in a 2L capacity four-neck flask equipped with a mechanical stirrer, reflux condenser and nitrogen inlet. PEG400 (as a dispersant), nitrogen flow was made to flow in, after 30 minutes of ultrasonic dispersion with 200W, 40kHz, in the RC5C centrifuge of Sorvall Instruments company, after 5 minutes of centrifugation with 12000rpm, remove the settled solid component, obtain remaining in Carbon nanotube dispersion liquid in the upper part. The carbon nanotube dispersion liquid was analyzed by a particle size analyzer (Microtrac, S3500). As a result, the maximum value of the particle size distribution was 15 μm or less, and the average value was 2.8 μm. Here, dissolve 95.5g of ODA (Wakayama, Japan) and 12.9g of p-PDA (DuPont), add 87.7g of s-BPDA (Ube, Japan) and 65.0g of PMDA (DAICEL, Japan) , to manufacture semicon...

Embodiment 2

[0050] Mix 1480gDMF and 1.96g of carbon nanotubes (Bayer company, multi-walled carbon nanotubes of C150P) and 1.96g of Triton X-100 in a 2L capacity four-necked flask equipped with a mechanical stirrer, reflux condenser and nitrogen inlet (As a dispersant), let nitrogen flow in, disperse with 200W, 40kHz ultrasonic waves for 30 minutes, centrifuge at 12000rpm for 5 minutes in an RC5C centrifuge from Sorvall Instruments, remove the settled solids, and obtain the remaining The carbon nanotube dispersion in the section. The carbon nanotube dispersion liquid was analyzed by a particle size analyzer (Microtrac, S3500). As a result, the maximum value of the particle size distribution was 10 μm or less, and the average value was 1.3 μm. Here, 95.5g of ODA (Wakayama Corporation, Japan) and 12.9g of p-PDA (DuPont Corporation) were dissolved, and 87.7g of s-BPDA (Ube Corporation, Japan) and 65.0g of PMDA (DAICEL Corporation, Japan) were added. , to manufacture semiconductive polyamic a...

Abstract

The invention provides a seamless belt and a preparation method thereof. The seamless belt has proper surface resistance to ensure excellent resistance uniformity and has excellent heat tolerance and finally provides excellent image when the seamless belt is suitable for the transfer printing belt.

Description

technical field [0001] The present invention relates to a seamless belt used in electronic equipment, conveyors, and the like, and a method for manufacturing the same. Background technique [0002] In general, belts are used in a variety of applications, and are used as major components instead of gears in industries that use rotating shafts and electric motors, such as electronic equipment, automobiles, and conveyors. In particular, in electronic equipment, used in copiers, laser printers, facsimile machines, etc., also for fixing and transferring toner images formed on copy paper or transfer paper, as a fixing belt or an intermediate transfer belt , conveyor belt. Timing belts and conveyor belts used in automobiles are also familiar components to ordinary people. [0003] Since the belt tends to generate static electricity during rotation, an antistatic function is required. Semiconductivity for antistatic function is also used as a physical property for toner transfer ...
