Definitions
- the present invention relates to a rubber composition. More specifically, the present invention relates to a rubber composition that is suitably used as a molding material for a bonded magnet for a sensor.
- Rubber magnets for sensors are used in magnetic encoders used in encoder parts such as speed sensors.
- NBR is generally used.
- the usage environment is as high as about 130 to 170 ° C.
- NBR with an upper limit temperature of 120 ° C can not be used.
- Silicone rubber, fluororubber, acrylic rubber, etc. can be used even at a temperature of C, but silicone rubber has a problem with oil resistance, and fluororubber significantly loses its flexibility when filled with magnetic powder. Therefore, the amount of magnetic powder is limited, and it is difficult to obtain a high magnetic force.
- Acrylic rubber has a remarkably low rubber strength when filled with magnetic powder, and does not serve as a needle.
- the present applicant has previously proposed a rubber composition for a magnetic encoder containing ethylene-methyl acrylate copolymer rubber, magnetic powder, and an amine-based vulcanizing agent, and vulcanized molding from the rubber composition.
- the magnetic encoder is not only excellent in heat resistance, water resistance and salt water resistance, but also can be highly filled with magnetic powder against rubber components, so it is also excellent in terms of magnetic force,
- the agent was foamed during vulcanization molding, and the amine vulcanizing agent had a problem of poor mold releasability and difficulty in workability.
- Patent Document 1 Japanese Patent Laid-Open No. 2004-26849
- An object of the present invention is to provide a highly filled powder of magnetic powder that can be effectively used as a bond magnet for sensors, etc., using an ethylene-alkyl acrylate copolymer rubber having an amine vulcanizable group as a binder. It is an object of the present invention to provide a composition that has no foaming during vulcanization molding and has excellent processability such as mold releasability.
- the strong object of the present invention is to provide ethylene-alkyl acrylate copolymer rubber 100 parts by weight, EP DM 5-40 parts by weight, ⁇ -olefin oligomer 1-40 parts by weight, organic peroxide cross-linking agent 0.5- This is achieved by a rubber composition containing 4 parts by weight, 0.5 to 4 parts by weight of an amine vulcanizing agent and 300 to 1000 parts by weight of magnetic powder.
- the rubber composition according to the present invention has a mold adhesive point, which has been a drawback of the ethylene-alkyl acrylate copolymer rubber having an amine vulcanizable group, by adding ⁇ -olefin oligomer.
- Improved and further combined with EPDM and added organic peroxide significantly improved vulcanization characteristics, solved the problem of foaming due to insufficient filling and insufficient vulcanization and mold adhesion.
- EPDM by using EPDM together, the ⁇ -olefin fin oligomer is prevented from bleeding, and a synergistic effect is exhibited in three points: roll kneadability, improvement of mold non-adhesiveness, and suppression of foaming.
- the obtained vulcanizate has sufficient performance as a rubber magnet for sensors.
- An ethylene-alkyl acrylate copolymer rubber represented by an ethylene-methyl acrylate copolymer rubber and an ethylene-ethyl acrylate copolymer rubber is an amine vulcanization type and a peroxide crosslinking type 2
- peroxide cross-linked type unreacted peroxide decomposition product gas generated during cross-linking may remain in the vulcanized rubber and cause foaming. Therefore, it is desirable to select the ammine vulcanization type when the magnetic powder is highly charged by about 500 parts by weight or more per 100 parts by weight of the copolymer rubber.
- an epoxy group or a hydroxyl group-containing monomer or the like is contained in the ethylene-alkyl acrylate copolymer rubber.
- a copolymer is used.
- Epoxy group-containing butyl monomers include glycidyl (meth) acrylate, allyl glycidyl ether, glycidyl vinyl ether. And alicyclic epoxy group-containing (meth) acrylate.
- hydroxyl group-containing vinyl monomer examples include 2-hydroxyethyl (meth) acrylate, 2-hydroxypropyl (meth) acrylate, 3-hydroxypropyl (meth) acrylate, 4-hydroxybutyl (meth ) Atarirate is used.
- These bur monomers are generally used in the copolymerization reaction as a crosslinking point forming monomer in an amount of about 0.1 to 10% by weight.
- amine vulcanization cannot be performed, so that it is not suitable for use in the present invention.
- An ethylene-alkyl acrylate copolymer rubber preferably 5 to 40 parts by weight, preferably 5 to 20 parts by weight of EPDM is added per 100 parts by weight of ternary AEM.
- the addition of EPDM improves the vulcanization characteristics, greatly improves the processability when ⁇ -olefin oligomer as a plasticizer is added, and improves the non-foamed state.
- the ratio is less than this, the a-olefin oligomer plasticizer bleeds on the surface of the rubber composition, so that the roll kneadability deteriorates.
- the addition ratio is higher than this, the productivity reduction force S due to the decrease in the vulcanization rate is brought about.
- the ⁇ -olefin fin oligomer includes, for example, ⁇ having 6 to 14 carbon atoms such as hexene-1, heptene-1, otaten-1, nonene-1, decene-1, dodecene-1, tetradecene-1, and the like.
- -Olefin oligomers having a number average molecular weight of about 400 to 2000 and preferably liquid at normal temperature for handling. Actually, commercially available products such as BP product Deyuracin 170 and Mitsubishi Chemical product Dialene 10 can be used as they are.
- ⁇ -olefin oligomers are used in a proportion of 1 to 40 parts by weight, preferably 1 to 20 parts by weight per 100 parts by weight of the ternary system. Addition of the ⁇ -olefin oligomer at such a ratio is a force for improving the non-stick property of the mold. Addition at a ratio higher than this deteriorates the roll kneading property.
- a peroxide crosslinking agent and an amine vulcanizing agent are used in combination. Specifically, 0.5 to 4 parts by weight, preferably 0.5 to 2 parts by weight of an organic peroxide crosslinking agent per 100 parts by weight of the ternary system and 0.5 to 4 parts by weight, preferably 0.5 to 2 parts by weight of an amine vulcanizing agent. Part by weight is added for use.
- a peroxide crosslinking agent preferably 0.5 to 2 parts by weight of an organic peroxide crosslinking agent per 100 parts by weight of the ternary system
- 0.5 to 4 parts by weight preferably 0.5 to 2 parts by weight of an amine vulcanizing agent. Part by weight is added for use.
- foaming occurs and the mold adhesion increases immediately.
- ternary systems In the case of single polymers, foaming occurs immediately and plasticizers are added.
- organic peroxides as peroxide-based crosslinking agents include di-tertiary butyl peroxide, dicumyl peroxide, 2,5-dimethyl-2,5-di (tertiary butyl peroxide) hexane, 2,5-dimethyl-2,5-di (tert-butylperoxy) hexyne-3, 1,1-di (tertiarybutylperoxy) -3,3,5-trimethylcyclohexane, etc. 2,5-dimethyl-2,5-di (tert-butylperoxy) hexane and 1,1-di (tert-butylperoxy) -3,3,5-trimethylcyclohexane are used.
- Examples of the amine vulcanizing agent include aliphatics such as hexamethylenediamine, hexamethylenediamine carbamate, hexamethylenediamine cinnamaldehyde adduct, hexamethylenediamine benzoate, and diamino-modified siloxane.
- Polyamine compounds such as 4-methylenebiscyclohexylamine, bis (4-amino-3-methyldicyclohexyl) methane, 4,4'-methylenebiscyclohexylamine-cinnamaldehyde adduct Or m-phenol-diamine, 4-diaminodiphenyl ether, p-phenol-diamine, ⁇ , ⁇ '-ethylenedialine, 4,4 '-( ⁇ -phenol-isopropylidene) diline, 4,4 '-(m-phenol-diisopropylidene) dialine, 3,4'-diaminodiphenyl ether, 4,4'-diaminodiphenyl sulfone 2,2-bis [4- (4-aminophenoxy) phenol] propane, bis [4- (4-aminophenoxy) phenol] sulfone, bis [4- (3-aminophenoxy) phenol] sulfone 4,
- a co-crosslinking agent made of a polyfunctional unsaturated compound is preferably used in combination.
- Polyfunctional unsaturated compounds include, for example, ethylene glycol di (meth) acrylate, propylene glycol di (meth) acrylate, triaryl (iso) cyanurate, trimethylolpropane tri (meth) acrylate, triallyl trimellitate.
- These co-crosslinking agents are about 0.1-10 parts by weight per 100 parts by weight of ternary AEM, Preferably it is used in a proportion of about 0.5 to 5 parts by weight. If the proportion of use is less than this, sufficient vulcanization speed and vulcanization properties cannot be obtained. On the other hand, if the proportion is used more than this, the elongation value will be significantly reduced.
- Ferrite magnet powder or rare earth magnet powder having a particle size of about 0.5 to 10 ⁇ m is generally used as the magnetic powder. Ferrite magnet powder is used, although it is low compared to. Among the ferrite magnet powders, strontium ferrite powder or norium ferrite powder is preferably used from the viewpoint of magnetic force. These magnetic powders are added to 20 g of magnetic powder by adding 1.5 ml of 5 wt% polybulualcohol aqueous solution, placed in a cylindrical mold with a diameter of 25.4 mm, and pressed under a pressure of 1 ton / cm 2 (98 MPa). Thus, it is preferable to use a dust magnet with Br of 1600G or more and iHc of 2000 Oe or more when the residual magnetic flux density Br and the coercive force iHc are measured with a DC magnetometer.
- the strong magnetic powder is used in a ratio of about 300 to 1000 parts by weight, preferably about 400 to 900 parts by weight, per 100 parts by weight of the copolymer rubber. If the blending force is less than this, the magnetic force as an encoder is not sufficient, but if it is used at a blending rate higher than this, the flexibility of the vulcanized product will be impaired.
- reinforcing agents represented by carbon black, anti-aging agents, plasticizers, processing aids, vulcanization aids, etc.
- reinforcing agents represented by carbon black
- anti-aging agents plasticizers
- processing aids processing aids
- vulcanization aids etc.
- These components are kneaded using a closed kneader and an open roll, and the kneaded product is injected under conditions of about 150 to 200 ° C and about 0.5 to 60 minutes. Molded by pressure molding methods such as molding, compression molding and transfer molding.
- the forming is performed in the form of vulcanization adhesion with a metal plate such as a stainless steel plate or a cold rolled steel plate as a support ring of the encoder, prior to vulcanization adhesion, It is preferable to apply a commercially available adhesive such as phenol resin, epoxy resin, or silane.
- Roll kneadability Evaluates that rolls have good tackiness during kneading as ⁇ , bad, and X (badging)
- Mold non-stickiness Evaluates that there is no stickiness to the mold during vulcanization, and evaluates it as X
- Foaming condition 125 x 230 x 2mm vulcanized sheet (test piece) with no foaming on the surface, ⁇ for foaming, X for foaming on the entire sheet
- Residual magnetic flux density ( ⁇ ) Using an injection molding machine capable of magnetic field molding, a test piece with a diameter of 22 mm and a thickness of 1 mm was formed in a magnetic field of 0.8 mT, and this test piece remained in the thickness direction with a DC magnetizer. Wear until magnetic flux density is saturated Measured with a flux meter connected with a search coil by stacking three magnetized and magnetized test pieces.
- Example 1 the EPDM strength was changed to 3 parts by weight.
- Example 1 the amount of ⁇ -olefin oligomer was changed to parts by weight.
- Example 1 EPDM was not used.
- Example 1 no a-olefin oligomer was used.
- Example 1 the amount of ⁇ -olefin fin oligomer was changed to 50 parts by weight.
- Example 1 the same amount of a polyether plasticizer (Asahi Denshi product RS-700) was used in place of the ⁇ -olefin fin oligomer.
- Example 1 instead of the ⁇ -olefin fin oligomer, the same amount of a phosphate plasticizer (Nippon Nippon Science Co., Ltd., DOS) was used.
- DOS phosphate plasticizer
- Example 3 From the comparison between Example 3 and Comparative Example 2, it can be seen that the non-stick property of the mold is improved by the addition of the ⁇ -olefin oligomer. However, adding an excessive amount of ⁇ -olefin oligomer deteriorates the kneading ability of the mouth.
