Multifunctional Amine Compoundsadmin
Mainly used for special synthetic rubber, such as acrylic rubber and fluorine rubber cross-linking. Polyamine vulcanized fluorine rubber is characterized by the mechanical strength of vulcanized rubber, compressed water for a long time deformation of small, high-temperature long-term aging can still maintain good physical and mechanical properties, but easy to scorch, the processing safety adverse, and gradually developed a “closed Amine & quot; compounds, such as hexamethylenediamine carbamates, ethylenediaminocarbamates to improve process safety. When an amine is used as the vulcanizing agent, a metal oxide must be added. At this time, the metal oxide not only acts as an activator to accelerate the vulcanization reaction, but also is a acceptor in which fluorine generated in the vulcanization reaction is higher than hydrogen.
Products are triethylenetetramine, tetraethylenepentamine, hexamethylenediamine, methylene double o-chloroaniline, right, the ‘diaminodiphenyl methane, hexamethylene diamine carbamic acid Salts, ethylenediamine carbamates, sulfurizing agents CSI, 3,3’-dichlorobenzidine, N-methyl-N, 4-dinitrosoaniline, triisopropanolamine, trimethylol methyl Amine, curing agent HVA-2, alicyclic amine salt.
