Beschreibung
Zusammenfassung:	The invention discloses a silicon modified double cross-linking type aqueous polyurethane curing agent and a preparation method thereof. The aqueous polyurethane curing agent is formed by mixing and reacting polyisocyanate, organo silicone modified polyethylene oxide ether, organo silicone, a catalyst, a terminator and a proper amount of solvent. The invention relates to a synthesis method of the curing agent as well as a performance test and application of the curing agent. The hardness, water-resistance chemical resistance performance aspects of a paint film prepared by using the organo silicon modified curing agent is improved in the aspects of hardness, water resistance and chemical resistance.
