Abstract
The present invention relates to a kind of novel epoxy non-activated thinner and synthetic method thereof, be with benzyl alcohol, ethylenediamine, benzyl glycidyl ether as raw material, reacted prepared non-activated thinner.The non-activated thinner of present invention synthesis is a kind of nonactive, novel diluent that good toughness, modest viscosity, toxicity are little, this diluent synthesis technique is simple, both may be used in epoxy resin, it is also possible in firming agent, be a kind of novel epoxy non-activated thinner.
Description
Technical field
The present invention relates to a kind of diluent, particularly relate to a kind of epoxy non-activated thinner and synthetic method thereof.
Background technology
When benzyl glycidyl ether uses separately as epoxide diluent, because its strand is short, therefore at epoxy resin
Middle addition can not be too many, and solidified after-product performance is the best.Because it is that reactive diluent can not be added in firming agent,
The not so good ratio regulating glue.
Summary of the invention
For solving above technical problem, the invention provides a kind of being blended in benzyl alcohol, with benzyl contracting by ethylenediamine
Water glycerin ether reaction after extend strand, eliminate benzyl glycidyl ether reactivity, the simple epoxy of synthesis technique is dilute
Release the synthetic method of agent, improve its solidification and solidified after-product performance.
The present invention is achieved by the following technical solutions:
A kind of epoxy non-activated thinner, is with benzyl alcohol, ethylenediamine, benzyl glycidyl ether as raw material, reacted
The non-activated thinner prepared；
Described benzyl alcohol: ethylenediamine: the consumption mol ratio of benzyl glycidyl ether is 3.0～6.0: 1.0: 4.0
；
Described one nonactive epoxide diluent synthetic method is: the most first benzyl alcohol and ethylenediamine are mixed
Uniformly, adding in there-necked flask, open stirring, rotating speed controls, at 60～80 revs/min, to be gradually dropped benzyl glycidyl ether, instead
Answering temperature to control at 40～60 DEG C, the dropwise reaction time controls 2～6 hours, drips and reacts complete, intensification 70
～80 DEG C, continuing stirring reaction 2～4 hours, lower the temperature 40～50 DEG C, discharging i.e. obtains epoxide diluent finished product.
The positive effect of the present invention is: the epoxy non-activated thinner realized according to above technical scheme, is a kind of non-
The diluent that activity, good toughness, modest viscosity, toxicity are little, this diluent synthesis technique is simple, both may be used for asphalt mixtures modified by epoxy resin
In fat, it is also possible in firming agent, it it is a kind of epoxy non-activated thinner.
Detailed description of the invention
Embodiment 1:
Weigh benzyl alcohol 216.2g and ethylenediamine 30.1g and add in there-necked flask, open stirring, rotating speed control 60～
