Abstract
An improved magnetic plastic material is prepared from, by weight, 6-9 parts of acrylonitrile, 3-4 parts of diphenyl acyl peroxide, 20-34 parts of calcium oxide, 8-15 parts of methyl acrylate, 16-21 parts of Fe2O3, 7-14 parts of PET (polyethylene terephthalate), 2-4 parts of tert-butyl peroxybenzoate, 4-6 parts of aluminum oxide, 2-5 parts of isobutylene-isoprene rubber, 2-7 parts of carbon black, 7-13 parts of polyacrylic acid, 2-5 parts of coupling agents, 6-12 parts of neodymium iron boron, 25-40 parts of plastic and 4-12 parts of rare-earth-containing magnetic powder. The improved magnetic plastic material has the advantages of higher magnetism, good mechanical property, high bonding strength, higher strength and low cost.
Description
Technical field
The present invention relates to a kind of magnetic plastics material of improvement.
Background technology
Magnetic plastics is a kind of novel high polymer functional materials that the seventies grows up, and is one of the important foundation material in modern science and technology field.Common plastics do not have ferromegnetism, but utilize special method can form ferromagnetic material: one is the composition managing to change plastics, makes them have magnetic.Magnetic plastics has the characteristic of magneticsubstance and plastics concurrently, because magnetic plastics machining property is good, easy-formation, and dimensional precision is high, good toughness, lightweight, low price, easily produce in batches, therefore the miniaturization of electromagnetic equipment, lightweight, precise treatment and high performance are of great importance.It can record sound, optical, electrical information, thus being widely used in the numerous areas such as electric, instrument, communication, daily necessities, assembling assembly, micromotor magnet steel, automotive instruments instrument, ignition distributor pad and pneumatic element magnet ring etc. as manufactured colour picture tube.In the field that some is new, sintered magnet is just progressively replaced by magnetic plastics, and meanwhile, magnetic plastics is lower than sintered magnet power consumption, can effective save energy.But also there are some undesirable phenomenons in existing technology, still can not meet service requirements, performance is lower, and magnetic effect is not good, still needs further improvement.
Summary of the invention
For the deficiencies in the prior art, the problem to be solved in the present invention is, provides a kind of magnetic plastics material of improvement, enhances magnetic, have good mechanical property and bond strength, add the intensity of matrix material, and cost is low.
For solving prior art problem, technical scheme provided by the invention is, a kind of magnetic plastics material of improvement, and it is made up of the raw material of following parts by weight:
Vinyl cyanide 6-9 part, diphenyl peroxide base acyl 3-4 part, calcium oxide 20-34 part, methyl acrylate 8-15 part, Fe2O316-21 part, PET7-14 part, Oxybenzene formic acid tertiary butyl 2-4 part, aluminum oxide 4-6 part, isoprene-isobutylene rubber 2-5 part, carbon black 2-7 part, polyacrylic acid 7-13 part, coupling agent 2-5 part, neodymium iron boron 6-12 part, plastics 25-40 part, rare earth magnet powders 4-12 part.
The invention has the beneficial effects as follows: the magnetic plastics material of improvement of the present invention, enhances magnetic, has good mechanical property and bond strength, add the intensity of matrix material, and cost is low.
