Abstract

A magnetic ring core raw material includes a raw material A and a raw material B. The raw material A is composed of 50% of ferrosilicon, 35% of sendust and 15% of crushed powder, and the total amountof the raw material A is 100%. The raw material B is composed of phosphoric acid, resin, lubricating powder and alcohol. The weight ratio of the raw material A to the phosphoric acid is 100:(0.1-0.3).The weight ratio of the raw material A to the resin is 100:(0.3-0.8). The weight ratio of the raw material A to the lubricating powder is 100:(0.1-0.5). The weight ratio of the raw material A to thealcohol is 100:(1-4.5).

Description

technical field [0001] The invention relates to the technical field of magnetic cores, in particular to a raw material for a magnetic ring core and a preparation method for the magnetic ring core. Background technique [0002] The magnetic ring core refers to the composite soft magnetic material made by mixing and pressing ferromagnetic powder and insulating binder. According to different materials, it mainly includes permalloy magnetic powder core, magnetic core and sendust magnetic powder core. [0003] With the development of technology, many devices have miniaturization requirements for electronic components, which requires the magnetic ring core to have high magnetic permeability, and sendust magnetic powder core and permalloy magnetic powder core have high magnetic permeability And the characteristics of low loss, because the price of sendust magnetic powder core is lower than permalloy, so it has replaced permalloy magnetic core in many occasions. [0004] At the sam...
