| titleOfInvention | A kind of asymmetric latency polyurethane curing agent and preparation method thereof |
| abstract | The invention discloses a kind of asymmetric latency polyurethane curing agent and preparation method thereof, the existing oxazolidine group of molecular structure has imine group again, has both oxazolidine and the dual functional group's effect of imines, it is low with viscosity, the features such as easy to operate, reaction speed is moderate, and solution is honored as a queen almost without smell.Its composite character is cyclisation, aldehyde (ketone) imino of primary amino group and the esterification of carboxyl and hydroxyl that ethylol amine can be completed in a reaction kettle, without processes such as purification & isolations to intermediate product, process conditions are mild, no exhaust gas waste sludge discharge, and catalyst is recyclable to be reused.Primary raw material used is the aldehydes or ketones of p-aminobenzoic acid (or ester), diethanol amine and 1-13 carbon.40-150 DEG C of reaction temperature.The latent curing agent that the product can not only be used for polyurethane material is used but also as reactive diluent. |
