| titleOfInvention | A kind of preparation method of low free high compatibility polyurethane curing agent |
| abstract | The invention discloses a method for preparing a low-free high-compatibility polyurethane curing agent. Firstly, the raw materials are prepared according to parts by mass: (A) one kind of toluene diisocyanate or a mixture of two kinds of toluene diisocyanate, 40-70 parts, (B) ) Ester solvents with a boiling point ≤ 200°C, 23? ~27 copies, (C)? Trimethylolpropane, 5? ~20 parts, (D) complex polyol ethers, 1? ~20 parts, (E) isocyanate trimerization catalyst, 0.1? ~0.2 parts, (F) isocyanate trimerization inhibitor, 0.1? ~0.3 part; the present invention first utilizes different temperature conditions to react most of the free toluene diisocyanate; Remove, so that the content of free toluene diisocyanate in the prepared curing agent product meets the latest national standard requirements, and the obtained product has high solid content, low viscosity, good compatibility, good stability, and the paint film performance remains unchanged after the paint is formulated. |
