Production method of ultra-low-viscosity ethyl cellulose for electronic paste

The invention relates to the field of ethyl cellulose preparation methods, and concretely relates to a production method of ultra-low-viscosity ethyl cellulose for electronic paste, which can effectively improve the qualified rate of the prepared ultra-low-viscosity ethyl cellulose. The production method comprises the following steps: firstly, refining and washing an ethyl cellulose crude product for electronic paste, meanwhile, adding water, a washing assistant and a viscosity reducer during refining and washing, then heating, boiling and washing, performing centrifugal dewatering, and repeating the rinsing and dewatering operation for 3-5 times to finally obtain the ultra-low-viscosity ethyl cellulose for the electronic paste. Acid and oxalic acid are added during rinsing for the first time. The method is especially suitable for production of the ultra-low viscosity ethyl cellulose for the electronic paste. 本发明涉及乙基纤维素制备方法领域，尤其是一种有效提高制备特低粘乙基纤维素的合格率的电子浆料用特低粘乙基纤维素生产方法，包括如下步骤：首先将电子浆料用乙基纤维素粗制品进行精制洗涤，同时在精制洗涤时加入水、
