2017-4-19 13:48:00
Do not need to use organic acid salt of type I waterborne epoxy crosslinking agent, Stark, benzene dimethylamine reaction between epoxy resin and excess epoxy amine adduct generated end, reacts with end carboxyl polyether glycol generate amide, amine, the sealing side type I waterborne epoxy crosslinking agent.
New water-based epoxy crosslinking agent products namely Epilink701, Anquamine670, Anquamine456 have been successfully used in steel structures,.
Epilink701, it is a kind of aliphatic amine emulsion polymer quality, solid mass fraction of 55%. The products can be smoothly emulsification liquid epoxy resin. The crosslinking agent high molecular mass, the drying time is much faster than high VOC solvent coatings.
Now through the liquid epoxy emulsion crosslinking agent of good film forming and dry, may be obtained with good resistance to water and wet sticky relay, zero VOC content of dry coating, can be used for metal protective primer and self-leveling floor coatings.
Anquamine670, is a modified aliphatic amine solution, the solid mass fraction of 65%. This crosslinking agent emulsification liquid epoxy resin easily and form a uniform film, good adhesion on most of the base material.
This kind of crosslinking agent without using organic acid salt, and thus enhance the water resistance and corrosion resistance, the drying time is the shorter of the traditional water crosslinking agent. The main characteristic of this product is that it has good compatibility with ordinary Portland cement, can be used for ? # green concrete coating and epoxy cement mortar.

Anquamine456, is based on the hydrophobic PCPA alicyclic amine modified products, with the epoxy resin has excellent compatibility. Most type I part as emulsifier, crosslinking agent used amine and the product adopted by the method is a kind of nonionic surfactant, connected to the excessive high hydrophobic - hydrophobic oil structure, so that half of the modified amine remain very low solubility in water and can quickly spread to the water at the same time.
In order to ensure the coating at room temperature can be completely crosslinking, through bifunctional coupling agent to low water solubility, low Tg flexible amine grafted onto modified alicyclic amine.
Commonly used coupling agent for epoxy resin and dimer fatty acid, and water soluble polymer is usually polyoxyethylene amine. Being made of the crosslinking agent coating with high flexibility and impact strength, the drying rate is low, good water resistance and corrosion resistance of coating film, is an ideal corrosion resistance of paint. The use of these new crosslinking agent, making type I epoxy coatings in aspects such as corrosion resistance, quick drying performance have greatly improved, and applied in the metal anti-corrosion coatings.
Ji-liang zhou to polyether polyols two glycidyl ether (DGEPG), triethylene tetramine (TETA) and liquid epoxy resin (EPON828) as raw material, using two step synthesis method of a kind of nonionic type I extender chain water-based epoxy crosslinking agent. First use of TETA DGEPG chain extension reaction, generate TETA - DGEPG adduct, the crosslinking agent of introducing hydrophilic molecule flexible polyether chain segments.
Then use EPON828 chain extension reaction of TETA - DGEPG in crosslinking agent molecules into epoxy resin molecule chain segment, in order to improve the compatibility of crosslinking agent and liquid epoxy resin, the crosslinking agent has the function of the emulsification liquid epoxy resin finally vacuum distillation to remove the solvent and water to solid mass fraction is 50% ~ 50%, the preparation of a new nonionic type I from emulsified waterborne epoxy crosslinking agent.
