A method for processing graphite 2B resin lead core is characterized in that the method comprises the following steps:
(1) Squamous graphite is crushed into graphite powder with 680 meshes and 90-95 carbon content.
(2) Water-soluble wax 45-50 kg, clay 30-50 kg, sugar 10-12 kg and high-color carbon black 10-15 kg were placed in 102 kg of the main material; (3) The material of step (2) was stirred evenly and kneaded in kneader for 3-4 hours;
(4) The kneaded material was cold rolled to make the thickness of the material 03-0.5 mm and the moisture content 14%.
(5) Store the rolled material in storage tank for 72 hours for reserve.
(6) Put the material of step (5) into the core press and press out a certain scale of graphite water-soluble lead core.
The invention is based on graphite powder, chooses reasonable formula, and develops high-tech products by scientific production process and production and processing of lead core. Because the process of the invention is simplified and improved on the basis of the existing process, and the machine and equipment are not improved, it can be directly applied to the existing production process and is simple and feasible.
