Abstract
The invention discloses a magnetic anti-aging plastic which is composed of the following raw materials in parts by mass: 80-95 parts of magnetic powder, 5-10 parts of thermosetting resin, 1-4 parts of anti-aging agent, 2-6 parts of synthetic vegetable butter, 0.1-0.5 part of butyl stearate and 0.5-1 part of coupling agent, wherein the magnetic powder is ferrite magnetic powder of which the fineness is 1-1.5 mu m; the thermosetting resin is epoxy resin or phenolic resin; the anti-aging agent is one of antioxidant 1010, antioxidant 1076, triphenyl phosphite and triphenyl phosphite; and the coupling agent is titanate or silane. The prepared magnetic anti-aging plastic is low in cost, excellent in magnetic performance and aging resistance and wide in application area, and can be easily subjected to machine shaping.
Description
Technical field
The present invention relates to a kind of plastics, relate in particular to the anti-aging plastics of a kind of magnetic.
Background technology
Plastics duration of service is long easily aging, and can not biological degradation in physical environment, very large to the destruction of natural ecological environment after therefore discarded.In addition, some plastics are as there is no the material of mutual adhesion in block toy, thereby easily cave in, and easy-formation not can not meet modern people's life requirement.
Magnetic plastics is compared with magnet, except magnetic energy is general, use temperature low, other performances are all than more excellent.It is easy to, and machine-shaping is all kinds of complicated shape goods, dimensional precision is high, mechanical property good, relative density is low, easy integrally combined, can be used for the less demanding occasion of some magnetic, as sensor, magnetotherapy appliance and the sports goods etc. of the loud speaker of refrigerator sealing strip, children's magnetic writing board, motor part, stereo set, earphone, telephone set, televisor accessory, instrument, communication equipment.The object of magnetic plastics exploitation is mainly for overcoming the unworkability of pure magneticsubstance, and this is also magneticsubstance developing direction from now on.
Summary of the invention
The technical problem solving: for the deficiencies in the prior art, the invention provides a kind of magnetic aging-resistant plastics, abundant raw material, cheap, magnetic property good, and being easy to machine-shaping is all kinds of complicated shape goods.
Technical scheme: the invention provides the anti-aging plastics of a kind of magnetic, formed by the raw material of following mass fraction: magnetic 80-95 part, thermosetting resin 5-10 part, antiaging agent 1-4 part, synthetic vegetable tallow 2-6 part, stearic acid butyl ester 0.1-0.5 part, coupling agent 0.5-1 part.
Described magnetic is ferrite magnetic class magnetic, and fineness is 1-1.5 μ m; Described thermosetting resin is epoxy resin or resol; Described antiaging agent is a kind of in antioxidant 1010, antioxidant 1076, triphenyl phosphite, triphenyl phosphite.Described coupling agent is titanic acid ester or silane.
Beneficial effect: because the present invention has adopted technique scheme, the anti-aging plastics cost of magnetic making is low, magnetic property and ageing resistance are excellent, are easy to machine-shaping, and Application Areas is extensive.
