| titleOfInvention | Thiourea modified low temperature curing agent and preparation method thereof |
| abstract | The invention relates to a thiourea modified low temperature curing agent and a preparation method thereof. The main component of the curing agent has the general structural formula shown in the formula I in the specification, wherein R is an alkyl chain with C atom number which is an even number; and n is equal to 1-1.5. The preparation method comprises the following steps: 1) weighing thiourea and polyamine, throwing thiourea and polyamine into a reaction vessel, raising the temperature and stirring the materials, preserving the heat and fully reacting; 2) slowly reducing the system temperature and vacuumizing in low vacuum; and 3) adding glyceryl triacetate and an epoxy reactive diluent in batches, stopping heating and stirring, cooling the product to room temperature and discharging the product. The low temperature curing agent has the following advantages: the prepared low temperature curing agent has good low temperature curing temperature and can be cured for 12 hours at minus 5 DEG C; and compared with the common thiourea curing agents with strong ammonia odor, the curing agent has light smell and lighter color, is basically non-irritating and does not affect construction operations. |
