| titleOfInvention | Amine composition and application thereof, polyurethane resin and preparation method and application thereof |
| abstract | The invention provides an amine composition which consists of diamine and monoamine in the molar ratio of (1.1-17.1):1. The invention further provides polyurethane resin and a preparation method thereof. The total amine value of the polyurethane resin is 1.20-20.0 mgKOH/g; the primary amine value is 8.7-38.8 percent of the total amine value; the secondary amine value is 5.6-82.6 of the total amine value; and the tertiary amine value is 8.7-55.6 percent of the total amine value. The preparation method comprises the following steps of: mixing high molecular dihydric alcohol with diisocyanate ester; adding a catalyst, and reacting at the temperature of 30-100 DEG C for 2-8 hours to obtain a dibasic alcohol polymer; reacting with a low molecular active hydrogen compound and a low molecular polyhydroxy compound; adding diamine which accounts for 0-70.6 percent of 100 percent by weight of diamine in the amine composition, and expanding a chain in an ester solvent; and adding the rest of diamine in the amine composition and all monoamine, and undergoing chain expansion and chain termination reactions in an ester and/or amine solvent to obtain polyurethane resin. The prepared polyurethane resin has the advantages of high physical and mechanical properties and high-temperature stewing resistance. |
