一种用于半导电胶辊的中阻值耐磨涂层及其制备方法
摘要：
本发明公开了一种用于半导电胶辊的中阻值耐磨涂层，由以下重量份的原料制成：95-110份的热固型液态酚醛树脂；15-25份的有机酸类固化剂；6-7.5份的聚氨酯导电剂；0.02-0.05份的有机硅类流平剂；0.003-0.006份的聚醚改性硅油消泡剂。还提供了一种上述中阻值耐磨涂层的制备方法。本发明中阻值耐磨涂层的电阻值为106-107数量级欧姆，符合使用要求，同时，使激光打印机中碳粉匣里的半导电胶辊耐磨性能更好，降低半导电胶辊的汰换率，增强了性能，延长了使用寿命，打印纸张数更多，从原本的3000-5000张大幅度提升，达到36000-42000张。
摘要（英）：

The invention discloses a medium-resistance wear-resistant coating for a semiconductive rubber roller, which is prepared from the following raw materials in parts by weight: 95-110 parts of thermosetting liquid phenol formaldehyde resin, 15-25 parts of organic acid curing agent, 6-7.5 parts of polyurethane conductive agent, 0.02-0.05 part of organosilicon leveling agent and 0.003-0.006 part of polyether modified silicon oil defoaming agent. The invention also discloses a preparation method of the medium-resistance wear-resistant coating. The resistance of the medium-resistance wear-resistant coating is 10<6>-10<7> orders of magnitude ohm, and conforms to the operating requirement; the medium-resistance wear-resistant coating enhances the wear resistance of the semiconductive rubber roller in the medium-carbon powder chest of the laser printer, lowers the replacement rate of the semiconductive rubber roller, enhances the properties, prolongs the service life, and greatly enhances the number of pieces of printer paper from 3000-5000 to 36000-42000.
