Polyetheramine (PEA) is a type of polymer with a polyether
structure as the main chain and an amine group as the terminal
active functional group. The chemical formula is C3n*3H6n**0OnN2.
Amino-terminated polyether has the following structure: x, y = *-n.
Polyetheramine is obtained by ammoniating polyethylene glycol,
polypropylene glycol or ethylene glycol/propylene glycol copolymer
under high temperature and high pressure. By choosing different
polyoxyalkylene structures, a series of properties such as
reactivity, toughness, viscosity and hydrophilicity of the
polyetheramine can be adjusted, and the amine group provides the
possibility for the polyetheramine to react with a variety of
compounds. Its special molecular structure endows polyetheramine
with excellent comprehensive performance. Commercialized
polyetheramine includes a series of products with monofunctional,
bifunctional, trifunctional and molecular weight ranging from **0
to ***0. It has been widely used in many fields such as polyurea
spraying, large-scale composite material production, epoxy resin
curing agent and automobile gasoline detergent.
English name: amino-terminated polyoxypropylene; Polypropylene
glycol bis(*-aminopropyl ether); polyetheramine; Polyetheramines;
*-(aminooxy)propan**-amine
CAS: ********0, *********3
Molecular formula: C3n*3H6n**0OnN2
Molecular weight: common products have a molecular weight of **0 to
***0
Soluble in organic solvents such as ethanol, glycol ethers,
ketones, aliphatic hydrocarbons and aromatic hydrocarbons. D***0 is
soluble in water, D***0 is partially soluble in water, and D****0
is insoluble in water.
The exothermic temperature of the end-group polyether cured epoxy
resin is reduced, and the product is colorless and transparent,
high gloss, toughness, and heat shock resistance. Amino-terminated
polyether has high boiling point, low vapor pressure, low toxicity,
and is potentially irritating to the skin.
LD*0: ***0mg/kg (D***0), **0 (D***0), **0 (D****0), **0
(T***3).
Used as a toughening curing agent for epoxy resin adhesives. It can
be used alone or mixed with ordinary polyetheramines. The reference
dosage is ****0 parts, and the curing conditions are
*0ºC/2h***5ºC/3h.
Of course, it can be cured at room temperature, but the bonding
strength is not high. Only D***0 and D****0 are mixed at *0:*5.
After curing at room temperature/7d, the peel strength is as high
as *8.4kN/m and the shear strength is *1.2mPa.
In addition, E**1: D***0=**0:*0 or E**1: D***0=**0:*4, with 4 parts
of methanol as an accelerator, the epoxy resin can be cured well at
room temperature. Amino-terminated polyether has low activity and
longer construction time. Adding a small amount of accelerator
nonylphenol (****0 parts per **0 parts of epoxy resin) can
significantly accelerate the curing reaction speed and improve
moisture resistance.
Amino-terminated polyether has low viscosity, colorlessness, good
compatibility with epoxy resin, long pot life and high bonding
strength. Excessive use of amino-terminated polyether will reduce
the bonding strength of epoxy adhesives. It can also be used as an
active chain extender for polyester. Also used as curing agent for
polyurethane and polyurea.
