Daim ntawv thov
ADNOX® 565 yog qhov hnyav molecular;non-staining, multifunctional antioxidant tsim rau stabilization ntawm unsaturated elastomers (BR, IR, SBR, SIS, SBS, thiab lwm yam), kub yaj adhesives, thiab rosin ester tackifier resins.
Keeb kwm
Antioxidant 565 yog ib qho polymer multifunctional hindered phenolic antioxidant, feem ntau yog tsim rau tom qab ua kom ruaj khov ntawm cov roj hmab tsis zoo, zoo heev rau elastomers, thiab tuaj yeem tiv thaiv cov ntaub ntawv los ntawm kev tsim khoom, ua thiab siv zaum kawg.Thermal oxidative degradation.Nws yog ib qho zoo heev antioxidant thiab photothermal stabilizer rau ntau yam resins.Nws muaj cov yam ntxwv ntawm qhov sib ntxiv me me, tsis tshua muaj hluav taws xob, xim nrawm nrawm, thiab tuaj yeem tiv thaiv kev tsim cov gel.Zoo heev hauv cov elastomers nram qab no: cis-butadiene roj hmab (BR) isoprene roj hmab (IR) styrene-butadiene roj hmab (SBR) nitrile-butadiene roj hmab (NBR) carboxylated styrene-butadiene latex emulsion polystyrene-butadiene roj hmab (ESBR) kua polymerization Styrene- butadiene roj hmab (SSBR) thermoplastic styrene-butadiene roj hmab SBS thermoplastic styrene-butadiene roj hmab SIS kuj tseem siv tau rau cov nplaum, ntuj thiab hluavtaws resins, xws li EPDM, ABS yas, polyamide (nylon, PA), siab Impact polystyrene (HIPS) thiab polyolefins.ABS yas yog ib qho kev hloov kho polystyrene yas tsim los ntawm peb yam khoom raws li acrylonitrile (A), butadiene (B) thiab styrene (S).ABS yas tuaj yeem siv los ua cov yas zoo nkauj nrog cov qauv embossed, thiab lwm yam.
Lub synthesis ntawm Antioxidant 565 yog tshawb xyuas hauv qhov kev tshaj tawm no.2,6-di-tert-butylphenol, raws li thawj substrate, yog nitrated rau 2,6-di-tert-butyl-4-nitrophenol nyob rau hauv 95% tawm los.2,6-di-tert-butyl-4-nitrophenol txo mus rau 4-amion -2,6-di-tert-butylphenol nrog hydrogen nyob rau hauv muaj Raney Ni los yog Pd / C.Txhawm rau tiv thaiv kev puas tsuaj ntawm 4-amion -2,6-di-tert-butylphenol thaum raug huab cua, 4-amion -2,6-di-tert-butylphenol raug tso cai rau hnov mob nrog Cyanuric chloride yam tsis muaj kev sib cais los ntawm 6-(3. ,5-di-tert-butyl-4-hydroxy) laniline-2,4-dichloro-1,3,5-triazin hauv 95% tawm los rau 2 kauj ruam.
Cov tshuaj tiv thaiv ntawm 6-(3,5-di-tent-butyl-4-hydroxy) aniline-2,4-dichloro-1,3,5-triazin nrog 2 qhov sib npaug ntawm n-Octylthiol muab cov khoom kawg 6-(3, 5-di-tert-butyl-4-hydroxy aniline-2,4-bis (octylthio)-1,3,5-triazin hauv 94% tawm los.
