| titleOfInvention | A kind of Polyether hydrophilic agent with zwitter-ion group and preparation method thereof and a kind of Water Dispersible Polyisocyanates composition |
| abstract | The invention discloses a kind of Polyether hydrophilic agent with zwitter-ion group, its structural formula is: n ; This has the preparation method of the Polyether hydrophilic agent of zwitter-ion group, comprises step: the 1) polyethers of synthesis containing tertiary amine group; 2) synthesis has the polyethers of zwitter-ion group.A kind of Water Dispersible Polyisocyanates composition, it is preparation like this: polyisocyanates, the Polyether hydrophilic agent with zwitter-ion group are reacted in the presence of a catalyst, add Benzoyl chloride, stopped reaction after reaction 2.5-3h.The Water Dispersible Polyisocyanates solidifying agent that the present invention adopts this zwitter-ion properties-correcting agent to prepare has better emulsifying property, polyisocyanate curing agent just can be made to obtain good water dispersible property with the hydrophilic modifying agent of small amount.And the impact of pH value on curing agent emulsion stability can be reduced, improve the working life of the suitable solidifying agent of polyisocyanates. |
