Abstract
The invention discloses a flexible epoxy curing agent and a synthesis method thereof. The curing agent is prepared by reacting octyl glycidol ether and diethylenetriamine used as raw materials. The curing agent has the advantages of moderate viscosity, low reaction activity, low maximum exothermic peak temperature, low toxicity and simple technique, can be widely used in the fields of self-leveling floors, adhesives, paints, architectural adhesives, sealing materials and the like, and is a novel flexible epoxy resin curing agent.
Description
Technical field
The present invention relates to a kind of solidifying agent, relate in particular to a kind of flexible epoxy solidifying agent and synthetic method thereof.
Background technology
Diethylenetriamine is basic fatty amine curing agent, and because of shortcomings such as its activity of curing reaction are high, and cured article surface is undesirable, and working life is short and exothermic peak is high, and solidified after-product fragility is large, therefore directly application is restricted.
Summary of the invention
For solving above technical problem, the invention provides one taking diethylenetriamine as raw material, by reducing its reactive behavior after reacting with octyl glycidyl ether; Synthesis technique is simple, easy to operate, has improved cured product performance.
The present invention is achieved by the following technical solutions:
A kind of flexible-epoxy solidifying agent, is taking diethylenetriamine, octyl glycidyl ether as raw material, the solidifying agent making through reaction;
The consumption mol ratio of described diethylenetriamine and octyl glycidyl ether is 1.0: 1.0～1.2;
Described a kind of epoxy curing agent synthetic method is: first diethylenetriamine is added in there-necked flask in molar ratio, open and stir, rotating speed is controlled at 180～220 revs/min, splashes into gradually octyl glycidyl ether, and temperature of reaction is controlled at 35～50 DEG C, the dropwise reaction time is controlled 2～5 hours, drip and react complete, heating up 60～65 DEG C, continuing stirring reaction 2～3 hours, be cooled to below 50 DEG C, obtain epoxy hardener finished product.
The epoxy curing agent of realizing according to above technical scheme, a kind of modest viscosity, low, the highest exothermic peak temperature of reactive behavior is low, toxicity is little Novel curing agent, this solidifying agent synthesis technique is simple, can be widely used in the fields such as coating, electric encapsulation, architecture adhesion agent and sealing material, be a kind of novel epoxy hardener.
