A graphite 2B resin lead processing method is characterized by the following steps:
(1) the flake graphite was crushed into graphite powder, the number of the order was 680, and the carbon content was 90-95.
(2) in 102kg of the main material, water soluble wax 45-50kg, clay 30-50kg, sugar 10-12kg, high pigment black 10-15kg; (3) mix the material of step (2) and place it in the kneading machine for 3 to 4 hours;
(4) after the kneading material is crushed, the thickness of the material shall be 03-0.5 mm, and the moisture content is 14%;
(5) place the crushed material in the storage tank for 72 hours to spare;
(6) put the material of step (5) into the core machine and press out the graphite water soluble lead core of a certain scale.
The invention is based on the graphite powder, the rational formula is selected, and the technology of producing and processing lead core is used to develop high-tech products through scientific production process. However, because the present invention is simplified and improved on the basis of the existing technological process, it is not improved to the machine equipment, so it can be applied directly to the existing production process.
