Definitions
- the present invention relates to an EPDM composition. More particularly, the present invention relates to an EPDM composition suitably used as a vulcanized material of a heat resistant water-resistant seal part or the like.
- the compression set resistance characteristic of the seal part is an important characteristic value and can be considered as an indication of the life.
- the compression set resistance is also changed by the ethylene component propylene copolymer copolymer rubber, which is also changed by the compounding component of the rubber, by the gen component copolymerized there.
- Patent Document 1 Japanese Patent Application Laid-Open No. 2001-146537
- Patent Document 2 Japanese Patent Application Laid-Open No. 2003-128851
- An object of the present invention is to provide an EPDM composition that can withstand, for example, 200 ° C. or higher!
- a compelling object of the present invention is to use 5-ethylidene-2-norbornene [ENB] as a gen component EPDM 20-80 wt% and dicyclopentadiene (0 base? EPDM containing 80-20 parts by weight of EPDM, and EPDM composition containing 0.5-10 parts by weight of organic peroxide per 100 parts by weight of blend rubber.
- EMB 5-ethylidene-2-norbornene
- a seal component vulcanized and formed from the EPDM composition according to the present invention can be used as a balance, even when it is immersed in high-temperature water such as 200 ° C., 500 hours or 300 ° C., 24 hours. Good, showing various properties, especially improved in terms of compression set resistance.
- the product life of the seal part can be determined mainly by the compression set resistance, and when this value reaches about 80%, the life can be taken as the life.
- the seal part obtained from the EPDM composition of the present invention has an improvement in the compression resistance against permanent strain about 10% when compared at the same temperature as the conventional product. In fact, in the hot water of 300 ° C., the life of the conventional product is about 10 hours, but the one obtained from the EPDM composition of the present invention maintains seal performance even after 24 hours. If you have enough hot water resistance, then you can have it.
- ENB copolymerization EPDM and DCPD copolymerization EPDM has a ratio of 20-80% by weight, preferably 30- 70% by weight, and 80-20% by weight, preferably 70-30% by weight of the former. Used as a blend. By increasing the ratio of the former, the compression set resistance is improved, and by increasing the ratio of the latter, the hot water resistance is improved, and by changing the blend ratio within such a range according to the purpose of use, It is possible to obtain matched seal parts etc.
- the organic peroxide which is a crosslinking agent is used in a proportion of about 0.5-10 parts by weight, preferably about 2-7 parts by weight, per 100 parts by weight of the blended rubber.
- the organic peroxide for example, tertiary butyl hydroperoxide, tamene hydroperoxide, di-tert-butyl peroxide, tertiary-butyl tamyl peroxide, dicumyl peroxide, 2,5-dimethyl-2, 2, 5-di (tert-butyloxy) hexane, 2,5-dimethyl-2,5-di (tert-butyloxy) hexyne-3,1,3-bis (tert-butylpropoxyisopropyl) benzene, 1 1-bis (tert-butylperoxy) -3,3,5-benzene, 1,1-bis (tert-butylperoxy) -3,3,5-trimethylcyclohexane,
- EPDM composition containing the above respective components as essential components, 5 to 50 parts by weight, preferably 10 to 30 parts by weight of zinc oxide or titanium oxide is further added per 100 parts by weight of the blend rubber. This can further improve the compression set resistance.
- the composition may be prepared by triallyl isocyanurate, triallyl cyanurate, ethylene glycol dodecyl methacrylate, trimethylolpropane trimethacrylate, ⁇ , ⁇ '-m-f ⁇ ⁇ ⁇ ⁇ -maleimide. And the like.
- a cross-linking aid comprising a polyfunctional unsaturated compound such as a carbon black, a reinforcing agent or filler that becomes carbon black or white carbon, an anti-aging agent, etc.
- any kneading means eg, mixing rolls
- the cross-linking of the prepared composition which is carried out by using a mbally mixer, various kinds of polymers and the like, is generally compression-molded while being heated to a temperature of about 100-200.degree. C. for about 30 seconds to about 2 hours. It is carried out by applying a method, an injection molding method or the like.
- DCPD EPDM (the company's product EPT1045) 30 "dicumyl peroxide 5 //
- SRF carbon black 70 "Amine based anti-aging agent (Ouchi emerging products Noccle white Nocrac white) 1.5 / / Paraffin based process oil (Idemitsu Petrochemicals PW380) 5"
- the kneaded product was cross-linked at 180 ° C. for 6 minutes to prepare a test piece (150 ⁇ 150 ⁇ 2 mm) and a G25 size 0 ring.
- the following test was conducted on the obtained test pieces and 0 ring.
- Hot water immersion test JIS K6258 compliant (using test piece) Measure changes in physical properties after immersion at 200 ° C, 500 hours and 300 ° C, 24 hours
- Hot water compression set According to JIS K6262 (G25 size 0 ring use, compression ratio 25%)
- Example 1 the amount of ENB EPDM was changed to 30 parts by weight, and the amount of DCPD EPDM was changed to 70 parts by weight.
- Example 1 20 parts by weight of zinc oxide was further added and used.
- Example 1 the amount of ENB-based EPDM was changed to 50 parts by weight, the amount of DCPD-based EPDM was changed to 50 parts by weight, and 20 parts by weight of titanium oxide was further added and used.
- Example 1 the amount of ENB EPDM was changed to 100 parts by weight, and DCPD EPDM was not used.
- Example 1 the amount of DCPD EPDM was changed to 100 parts by weight, and ENB EPDM was not used.
- Example 1 the amount of ENB EPDM was changed to 90 parts by weight, the amount of DCPD EPDM was changed to 10 parts by weight, and 20 parts by weight of titanium oxide was further added and used.
- Example 1 the amount of DCPD EPDM was changed to 90 parts by weight, and the amount of ENB EPDM was changed to 10 parts by weight.
