| titleOfInvention | A kind of preparation method of light polyisocyanate curing agent |
| abstract | The present invention relates to a kind of preparation method of light polyisocyanate curing agent, it comprises: a) carry out purifying to raw material TriMethylolPropane(TMP), obtains the TriMethylolPropane(TMP) of carbonyl compound content lower than 0.1wt%; B) carbonyl compound content reacts in the reactor with conical liquid distributing disc lower than the mixture of the TriMethylolPropane(TMP) of 0.1wt% or itself and small molecules dibasic alcohol and excessive diisocyanate component, obtains the liquid prepolymer reaction liquid containing excess diisocyanate monomer; C) adopt two-stage thin-film evaporator to remove monomer by the prepolymer reaction liquid that b) step obtains, through solvent latting drown, obtain the solidifying agent of diisocyanate monomer content lower than 0.5wt%.The polyisocyanate curing agent look number prepared based on present method can lower than 20Hazen. |
