Other new varieties of accelerators Currently, new types of accelerators are being researched to obtain accelerators with high efficiency of vulcanization, good processing safety, good resistance to reversion and high aging resistance. In addition, the variety of sulfur donors has gradually increased, and non-sulfur cross-linking systems have emerged. Moreover, it has been recognized that toxic promoters such as ethylene thiourea are being eggyiddwawo. .
(1) Triazine Promoter Ekisinga obukulu ku bino ye bis(2-ethylamino-4-diethylaminotriazinyl-6) disulfide, etumbula amaanyi amangi okusinga accelerators eza bulijjo. okusiiba era obukuumi okukola. sweeka wakati wa vobs ne cccells {ccessropys {ccessropys 1.} ne class NOBs ne cccessation eri nobs nobs ne cccellys 1. Omuwendo mutono, mu mbeera y’okubeeramu 1.5 okutuuka ku 2.ebitundu 35 ebya kapiira ak’obutonde, ebitundu 0.3 byokka bye bisobola okukozesebwa mu kifo ky’ebitundu 0.5 ebya sulfenamide. Accelerator esobola okulongoosa eky’obugagga ky’okulwanyisa okuddamu kwa sulforaphane ku ddoozi ya sulfur entono, era esobola okukozesebwa mu styrene-butadiene rubber, isoprene rubber ne butyronitrile.
(2) Promoters such as thiocarbamoyl sulfenamide are mainly N-oxydiethylenethiocarbamoyl-N-oxydiethylene sulfenamide, which has high safety and vulcanization speed. Fast, the promotion is great. Suitable for styrene butadiene rubber, nitrile rubber, EPDM rubber and other general synthetic rubber. The compound used in an amount of 0.67 parts was vulcanized faster than 1 part of the sulfonyl accelerator. And can get satisfactory operational safety performance. The activity above 149℃C is very large, while below 149℃C can be added a small amount of accelerator NOBS, M or DM. (3) Thiophosphoryl accelerator bis(diethylthiophosphoryl) trisulfide This accelerator can be used as a sulfur donor in natural rubber. When part or all of the sulfur is replaced, the heat resistance of the vulcanizate can be improved, and the reversion property and compressive deformation property can be improved at the time of high temperature vulcanization. It is an excellent accelerator in EPDM rubber, safe in Okukola, okusiiba mu vulcanization, okulungi ennyo mu kuziyiza ebbugumu, okutali kufukumuka, era kirungi nnyo mu kuziyiza okunyigiriza okuteekebwamu{19}} kwawukana ku kwanguyiza okulala kungi n’abagaba ekibiriiti n’ekibiriiti mu ngeri nti tekireeta kuvundira kwa biwuzi bya poliyesita ebikwatagana ne kapiira.
