Example Embodiment
[0045] Example 1
[0046] 1. Preparation of emulsifier:
[0047] Add 39g polyethylene glycol 6000 (PEG6000) and 3g epoxy resin E-44 into the reaction kettle, heat to 85℃ under nitrogen atmosphere, stir to mix the two evenly, add 0.2g N,N-dimethyl Benzylamine catalyst for constant temperature reaction at 135°C. After a constant temperature reaction for 480 minutes, the temperature was lowered to 90° C., 1.8 g of octadecylamine was added, and the reaction was carried out for 240 minutes to obtain a white waxy product emulsifier.
[0048] The molecular formula of the emulsifier is: among them
[0049] R is
[0050] 2. Preparation of epoxy resin polyamine curing agent:
[0051] A mixture of 3.5 g of diethylenetriamine and 4.5 g of metaxylylenediamine was added to a reaction kettle equipped with a stirrer, condenser and thermometer. Dissolve 14.5g E-44 epoxy resin with 2.4g ethylene glycol monobutyl ether and 1.2g n-butanol to 30dm 3 ·H -1 Add the dissolved epoxy resin to the polyamine m...
