Beschreibung
Zusammenfassung:	The invention relates to the field of anticorrosive materials, and particularly discloses a low-viscosity curing agent, a light alloy coating and a coating preparation method. The low-viscosity curing agent is prepared from triethylene tetramine, epoxy resin, polyether polyol glycidyl ether and phenyl glycidyl ether according to the weight ratio of (3.066 to 3.358) to 10 to (1.875 to 2.500) to (0.90 to 1.08); the preparation method comprises the following steps: firstly, carrying out addition reaction on triethylene tetramine and polyether polyol glycidyl ether to obtain a primary addition product; then, carrying out addition reaction on the primary addition product and epoxy resin to obtain a secondary addition product; carrying out addition reaction on the secondary addition product and phenyl glycidyl ether to obtain a third addition product; and finally, diluting the third addition product with water to obtain the low-viscosity curing agent. The curing agent is low in viscosity, and the light alloy coatin
