Abstract
A preparation method of epoxy resin comprises the following steps: mounting a mixer, a thermometer, a condensation tube and a constant pressure dropping funnel on a four-opening flask; adding epoxy resin and 4,4'-bis-(sec-butylamino)-diphenylmethane into the four-opening flask according to the ratio of 1:1; heating the flask to 150 DEG C; performing reaction for 4 hours at the temperature; cooling the flask to 60 DEG C; adding hydroxyethyl acrylate; carrying out stirring for 1 hour until the materials are uniformly mixed; carrying out discharging.
Description
Technical field
The present invention relates to a kind of preparation method of epoxy resin, belong to the synthetic field of resin.
Background technology
Epoxy acrylic resin be by epoxy resin and acrylic or methacrylic acid in certain temperature and have esterification under the condition that catalyzer exists and.The epoxy resin adopting when the conventional epoxy acrylic resin in use is synthetic is at present E-44 or E-51.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of preparation method of epoxy resin is provided, glue-line transparency, luminance brightness after the epoxy acrylic resin being synthesized like this solidifies are all very good.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of preparation method of epoxy resin, comprise: in the four-hole boiling flask of agitator, thermometer, prolong, constant pressure funnel is housed, add 1:1 epoxy resin and 4,4 '-bis-Zhong Ding ADP methylmethanes, are warming up to 150 ℃, react 4 hours at this temperature, be cooled to 60 ℃, add Hydroxyethyl acrylate, stir 1 hour even to mixing of materials, discharging.
Further, a kind of preparation method of epoxy resin, epoxy resin is E-12.
The invention has the beneficial effects as follows: glue-line transparency, luminance brightness after the epoxy acrylic resin being synthesized like this solidifies are all very good.
Embodiment
Below principle of the present invention and feature are described, example, only for explaining the present invention, is not intended to limit scope of the present invention.
Embodiment 1
In the four-hole boiling flask of agitator, thermometer, prolong, constant pressure funnel is housed, the epoxy resin that adds 10 parts is E-12 and 10 part 4,4 '-bis-Zhong Ding ADP methylmethanes, be warming up to 150 ℃, at this temperature, react 4 hours, be cooled to 60 ℃, add 10 parts of Hydroxyethyl acrylates, stir 1 hour even to mixing of materials, discharging.
concrete verification experimental verification
| ? | Embodiment 1 |
| Transmittance test | Transparency is fine |
As can be seen from Table 1, the obtained hungry epoxy resin of the present invention, transparence is fine.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
