Epoxy resin is used to crosslinking agent with modified amine coating
The commonly used epoxy resin is used to crosslinking agent with modified amine, including amides, polyamide and amine admixture.
Epoxy resin with modified amine crosslinking agent of polyamide HZ3982, polyamide 1 h7005w, modified amine CURE8537, such as modified amine AnquaWhite 3 kind of crosslinking agent and epoxy resin compatibility is poor, lead to applicable period short and poor water resistance and anticorrosive, all require modification to improve them.
D.H.K lein, developed the first generation of epoxy resin with modified amine and epoxy cross-linking agent EH - 1 more hydrophobic adduct EH - 2, and in the preparation of EH - 3 crosslinking agent [poly (amino cyclohexylamine) by 70% and 30% benzyl alcohol].
The amino combination of the amino group on the secondary carbon atom, the reactivity is more moderate, so that the epoxy resin particles in the dispersive body are not exposed to the surface locally, and the subsequent crosslinking agent is blocked.Benzene methanol helps to form film and toughening film, and its hydroxyl group promotes crosslinking reaction after crosslinking.
Klein, two glycidyl polyoxyethylene ether get epoxy resin and bisphenol A epoxy resin reaction you repose, again with polyethylene oxide propylene diamine and isophorone diamine reaction generated amine epoxy crosslinking agent.
Stark et al. used epoxy resin and an overdose of toluene dimethylamine reaction to generate an amine addition, and the carboxyl polyether alcohol to form amide an amine, and then the sealed end of the water-based epoxy crosslinking agent.
Elmore, etc to ethylene polyamine and solid epoxy resin reaction end amino epoxy amine adduct, reacts with end carboxyl polyether alcohol amide ammonium compound was, with single epoxy compound sealing side, finally made amide amine epoxy crosslinking agent.
Zhu baoying et al. used polyethylene glycol diglycidyl ether, bisphenol A type epoxy resin, aliphatic polyamine or aromatic polyamines to synthesize the non-ionic cryogenic crosslinking agent.The effects of different polyamines and different glycerine ether contents on the appearance, stability and crosslinking performance of crosslinking agent were studied, and the ratio of epoxy/amine hydrogen was confirmed to be 1:0.8.

Diethyltoluenediamine packingļ¼ net weight 200KG/ galvanized iron drum (a small cabinet pallet loaded 16 tons), 1000KG/IB barrels (a small cabinet loaded 18 tons or 23 tons of ISOTANK).
Zou Hailiang, octadecylamine and ethylene glycidyl ether reaction, made a kind of both ends of epoxy group, middle of hydrophobic alkyl chain double epoxy compound, reoccupy triethylene tetramine in sealing side, made a kind of nonionic since emulsified waterborne epoxy crosslinking agent, the liquid epoxy resin has good emulsification effect, excellent film performance.
Li chuxin et al. used polyether amine and DMP - 30 [3 - (dimethylamine methyl) phenol as the raw material, and modified the modified mannithiamine (MAI) by the exchange reaction of amines.Then in the end to the senses of the homemade epoxy polymers (PEG - EP) and liquid epoxy resin (EP) as chain extender on modification, MAI and phenyl glycidyl ether (PGE) sealing side, by phase transformation is the new type of modified mannich amine epoxy crosslinking agent, the crosslinking product performance.
Liu Shengbo with liquid epoxy resin and triethylene tetramine addition reaction as raw material, made a amine epoxy adduct, then to a amine epoxy adduct in the blend of sealing side drops (butyl glycidyl ether and phenyl glycidyl ether);The epoxide in the end agent was reacted with the equivalent of the permide hydrogen in the additive, and then the hydrogen of the secondary amine was salted with organic acid and the sealed end.
Of the emulsified waterborne epoxy crosslinking agent and homemade since water-based epoxy resin emulsion with paint, the double function of both crosslinking and emulsification, and homemade amino acid modified waterborne epoxy resin with good compatibility, internal diffusion and crosslinking agent to the resin more easily, thus improve the system stability, mechanical properties and anticorrosion performance.
The prepared container intermediate paint was tested to meet the standard requirements and passed the test certification of the American KTA (us konlab) and the FDA (FDA).
