Abstract
The invention relates to plastic and particularly relates to magnetic plastic. The magnetic plastic disclosed by the invention is prepared from the following raw materials in parts by weight: 40-60 parts of plastic matrix, 20-50 parts of rare earth magnet neodymium-iron-boron magnetic powder, 5-15 parts of SMA (styrene maleic anhydride), 1-5 parts of lubricating agent, 0.1-1 part of azodicarbonamide and 0.1-0.5 part of antioxidant. The invention provides the magnetic plastic with light texture and good stability.
Description
Technical field
The present invention relates to the plastics technology field, particularly a kind of magnetic plastics and preparation method thereof.
Background technology
Along with social development, the application of magnet is also more and more extensive, from high-tech product to the most simply packing magnetic, applies at present the most still strong magnetic of neodymium iron boron and the ferrite magnet of light method.
Magnetic plastics is as a kind of new function material, and with it, intrinsic characteristic is widely used in the numerous areas such as electronics, electric, instrument, communication.Because the density of magnetic plastics is little, shock strength is high, can be cut, cut, holed, the processing such as welding, lamination and embossing can be not chipping while using, directly injection moulding.Simultaneously, can be processed into that dimensional precision is high, the goods of thin-walled, complex character, plastic band inserts goods, realize miniaturization, lightweight, precise treatment and the high performance of electromagnetic equipment.Therefore, new fields at some, sintered magnet is progressively replaced by magnetic plastics.Simultaneously, magnetic plastics is lower than the sintered magnet power consumption, meets the strategic plan of nation-building resource-conserving and environment-friendly society fully.
Summary of the invention
On the basis of existing technology, the invention provides a kind of novel magnetic plastics: provide that a kind of quality is light, the magnetic plastics of good stability.
The technical scheme adopted is:
