2017-2-21 11:57:07
Chain extender classification: chain extender chain extender has many category of all nationalities, under the quoted part category (not all quotes) :
Alcohol base of classification of chain extender chain extender.
aliphatic diol
Ethylene glycol
1, 3 - propanediol
1, 4 - butanediol, for polyurethane elastomer is most important.
2, 3 - butanediol
1, 4 - butanediol
1, 4 - dihydroxy butane
1, 5 - butyl glycol
1, 6 f diol
1, 4 - tetramethyl ethylene glycol
Four methylene 1, 4 - diol
aromatic diol:
1, 4 - dihydroxy - 1, 2, 3, 4 - tetrahydronaphthalene
Hydroquinone ether - HQEE 2
a polyol, suitable for as a crosslinking agent:
Trimethylolpropane (TMP) three alcohol
Pentaerythritol three alcohol base
Chain extender amino chain extender of classification: primary and secondary two ammonia and ammonia as chain extender agent and crosslinking agent. Aromatic amine has higher reactivity than fatty amine. The reaction of aromatic amine is influenced by space block and electronic to replace.
reactive diamine:
Primary amine double function mainly as chain extender for polyurethane, polyurea and epoxy resin, the adhesive property
Branch of polyether amine, and c b oxygen oxygen radicals
Poly (propylene oxide diamine
Aliphatic diamine blending
aromatic diamine:
DETDA - ethyl toluene diamine
Dichloro - 4, 4 '- diphenyl aminomethane (MOCA)
Aromatic diamine and MOCA blending
4, 4 'diamino diphenyl methane
Chinese name: Diethyl toluene diamine(DETDA)
Diethyltoluenediamine Raw material ：
TDA industrial, Sichuan production
Ethylene (Et) polymer grade, Shanghai production
TEA industrial imports
A reagent grade additives
diaminobenzene
Dimethoxy diamino biphenyl
Dimethyl diamino biphenyl
Diamino biphenyl
Dichloro diamino biphenyl
The reactivity of three amine chain extender categories: strong reactivity/crosslinking agent, chain extender agent for polyurethane. Can be used as a modifier and epoxy curing agent.
ther chain extender
methyl polyethylene glycol amine blending material, mainly as a curing agent for epoxy resin.
mercapto propionic acid and mercapto propionic acid salt in the polymerization reaction as chain transfer agent and crosslinking agent.
silicon resin chain extension agent, Wacker SB 72 chain extender is a kind of secondary butyl amine silane, and water will break under the influence of water and form a primary aliphatic amine, as RTV 1 - crosslinking agent of seepage prevention of amine of raw materials.
