    • 본발명은복사기나프린터, 팩시밀리등 화상형성전자기기의화상정착부에사용되는이음매없는정착벨트에있어서, 폴리아믹산용액과이온성금속함유물질을포함한이온성금속용액을혼합하여이온성금속함유폴리아믹산용액을제조하고, 이온성금속함유폴리아믹산용액을원통형성형몰드의외주면또는내주면에도포하고회전시켜필름층을형성하고, 형성된필름층을열처리하여경화시켜이미드화되고표면에금속저항발열체층이형성된관형필름을성형하는것을포함한발열정착벨트의제조방법을제공한다. 본발명에따르면정착벨트가히터로부터열을전달받지않고직접발열하는폴리이미드수지필름히터가되므로, 별도의히터가필요없어기존대비경량으로간소화한정착장치를제공할수 있으며, 전원의투입으로부터정착가능상태에이르기까지대기시간이짧고, 화상형성전자기기에사용되는전압에서고온의발열이가능하여열정착이고속화되는것이가능해진다.

    • PURPOSE: A seamless belt and a manufacturing method thereof are provided to ensure excellent picture when being applied as a transfer belt, by the increase of the heat resistance of the seamless belt. CONSTITUTION: A manufacturing method of a seamless belt is as follows. After the solution containing carbon nanotube of 100weight% and dispersing agent of up to 100weight% is ultrasonic-dispersed, centrifugation is made for the solution to get carbon nanotube dispersing agent. Tubular belt member rotates, and macromolecule resin comprising carbon nanotube dispersing agent and polyamic acid polymer is uniformly applied to the inner surface of the tubular belt member, wherein the ratio of the carbon nanotube to the polyamic acid polymer is 1weight% : 100weight%. The applied polyamic acid polymer on the inner surface of the tubular belt member is dried and cured. A seamless belt is separated from the tubular belt member.
    • 目的:提供无缝带及其制造方法,以通过无缝带的耐热性的提高来确保作为转印带施加时的优异图像。 规定:无缝带的制造方法如下。 将含有100重量%的碳纳米管和高达100重量%的分散剂的溶液超声分散后,进行离心分离,得到碳纳米管分散剂。 管状带构件旋转,并且包含碳纳米管分散剂和聚酰胺酸聚合物的高分子树脂均匀地施加到管状带构件的内表面,其中碳纳米管与聚酰胺酸聚合物的比例为1重量%:100重量%。 将管状带部件的内表面上施加的聚酰胺酸聚合物干燥并固化。 无缝带与管状带构件分离。
