Embodiment 1
[0036] A kind of emulsion that is used for cathodic electrophoretic paint, its main component and preparation process are as follows:
[0037]Put 1128 parts of epoxy resin E-51, 456 parts of bisphenol A, and 80 parts of xylene into the reaction kettle, raise the temperature to 120°C, add 4 parts of dimethylbenzylamine, raise the temperature to 140°C, and detect the obtained The epoxy value of the product, so that its epoxy value is 0.1578 ± 0.01. Cool down, add 400 parts of propylene glycol monomethyl ether, 20 parts of propylene glycol phenyl ether and 180 parts of ethylene glycol butyl ether, cool down to 90 ° C, add 101 parts of N-methylol acrylamide, 0.1 part of hydroquinone, 105 parts of di Ethanolamine, after reacting for 1.5 hours, add 45 parts of monoethanolamine, raise the temperature to 110°C, and react at 110±2°C for 2.5 hours. Cool down to 90°C, add 1000 parts of cross-linking agent (the releasable -NCO content is 2mol); cool down to 70°C, add 2 parts of BYK110, 2...
Embodiment 2
[0040] A kind of emulsion that is used for cathodic electrophoretic paint, its main component and preparation process are as follows:
[0041] Put 1362 parts of epoxy resin E-44, 456 parts of bisphenol A, and 80 parts of xylene into the reaction kettle, raise the temperature to 120°C, add 4 parts of dimethylbenzylamine, raise the temperature to 140°C, and detect the obtained The epoxy value of the product, so that its epoxy value is 0.145 ± 0.01. Cool down, add 400 parts of propylene glycol monomethyl ether, 20 parts of propylene glycol phenyl ether and 180 parts of ethylene glycol butyl ether, cool down to 90 ° C, add 101 parts of N-methylol acrylamide, 0.1 part of hydroquinone, 105 parts of di Ethanolamine, after reacting for 1.5 hours, add 45 parts of monoethanolamine, raise the temperature to 110°C, and react at 110±2°C for 2.5 hours. Cool down to 90°C, add 1000 parts of cross-linking agent (the releasable -NCO content is 2mol); cool down to 70°C, add 2 parts of BYK110, 2...
