▎ 摘　　要

NOVELTY - Magnetic plastic material comprises high temperature resistant nylon, where the high temperature resistant nylon is polyaromatic nylon, the thermal deformation temperature is more than 210℃, the density is less than 3.8 g/cm3, the surface magnetic strength is more than 5000 Gs, and the coercive force is more than 5 kOe. USE - Magnetic plastic material for use in a TWS earphone of a mainstream flagship cell phone.. ADVANTAGE - The magnetic plastic material provides good corrosion resistance and magnetic performance, at the same time, improving the magnetic plastic caused by adding magnetic component is bad wear resistance, easy to remove the problem of powder. It contains the presence of high molecular substance in polymer polymer, so that it has strong anti-corrosion ability, it does not need to surface out coating protection, it can greatly reduce the product cost. It provides the magnet and other parts can be combined molding means of injection molding, saving the secondary processing assembly cost, the molding and assembly cost is greatly reduced. It can be designed with a reasonable Haerbeck array, saving a lot of space of product inner part. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the magnetic plastic material, comprising refining the complex magnetic powder, nylon-type polymer and auxiliary agent to obtain the premix, extruding and granulating the premix compound to obtain the magnetic plastic material. DESCRIPTION OF DRAWING(S) - The drawing shows a process flow chart of a magnetic plastic material (Drawing includes non-English language text).
