Room temperature epoxy coatings modified crosslinking agent
2017-3-5 16:18:37
Room temperature epoxy coatings modified crosslinking agent, the waterborne epoxy crosslinking agent commonly used, mainly modified amine crosslinking agent, including amide Quito amine, polyamide and amine adduct.
Such as polyamide HZ3982, polyamide 1 h7005w, modified amine CURE8537, modified amine AnquaWhite, etc. But the above three kinds of crosslinking agent, poor compatibility with epoxy resin to apply period short and poor water resistance and anticorrosive, all require modification to improve them.
D.H.K lein, developed the first generation of water-soluble amine adduct 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 amine combining Yu Zhong carbon atoms, reactive moderate, make its contact dispersion of epoxy resin particles too early in the partial surface crosslinking, hinder the follow-up crosslinking agent penetration. Benzyl alcohol helps film-forming and toughening film, after crosslinking hydroxyl and promoted the crosslinking reaction.
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, benzene dimethylamine reaction between epoxy resin and excess generation side epoxy amine adduct, again with end carboxyl polyether alcohol to generate amide amine, then the waterborne epoxy crosslinking agent was sealed end.
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.
Bao-ying zhu with polyethylene glycol diglycidyl ether, such as bisphenol A type epoxy resin, aliphatic amine or aromatic amine synthesized non-ionic cross-linking water-borne epoxy crosslinking agent at low temperature. Studied the different polyamine, different content of glycerol ether the appearance, stability of crosslinking agent and crosslinking performance, the influence of the epoxy/amine hydrogen ratio is 1:0.8 crosslinking performance is best.
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
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 Chu new polyether amine and DMP - such as 30 [3 - (dimethylamino methyl phenol]) as raw material, using exchange reaction was modified mannich amine (MAI). 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 end capping agent of the epoxy group and the primary amine adduct hydrogen than reaction, according to the equivalent with organic acid and after the termination of secondary amine hydrogen into salt.
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.
As container intermediate paint preparation by the box to try meet standard requirements, and passed the KTA (Konstant laboratories, USA) and the FDA (us food and drug administration (FDA)) inspection certification, has obtained a patent for invention.
