Abstract

A preparation method of a modified epoxy resin is characterized by comprising the following steps: mixing 100 parts by weight of epoxy resin and 10 parts by weight of rosin, heating to a temperature of 150 to 160 DEG C to melt the mixture, adding 10 to 15 parts by weight of bisphenol A, heating to a temperature of 180 to 200 DEG C, stirring for 0.3 to 0.5 hour, cooling to a temperature of 90 to 100 DEG C, adding 12 to 30 parts by weight of formaldehyde and 1 to 3 parts by weight of promoter (hexamethylenetetramine), stirring for 2 to 2.5 hours at a constant temperature of 90 to 100 DEG C, adding 10 to 15 parts by weight of pentaerythritol, carrying out reactions for 2 to 2.5 hours under stirring, heating to a temperature of 270 to 280 DEG C, and carrying out vacuumizing for one hour to obtain the target product.

Description

Modified epoxy preparation method
Technical field
The invention belongs to a kind of modified epoxy preparation method.
Background technology
Colophonium is the Renewable resource of China's abundant, and annual production reaches more than 60 ten thousand tons, ranks first in the world.It is by a series of Resinic acid composition, there are chemical constitution and the mulitiple chiral centers of uniqueness, the carboxyl in structure and phenanthrene ring frame can be carried out A series of chemical modification, is a kind of natural chiral source material.Colophonium can obtain a series of deep processings through chemical modification Product, the every field being widely applied in daily life,.2-10 mentioned by the value ratio raw material Colophonium of these deep processed products Times, or even decades of times.
Content of the invention
It is an object of the invention to：For the deficiencies in the prior art, a kind of modified epoxy preparation method is proposed.
The modified epoxy preparation method of the present invention it is characterised in that：By weight, 100 parts of epoxy resin, Colophonium 10 Part, 150-160 DEG C of melting of heating, plus bisphenol-A 10-15 part, 180-200 DEG C of intensification, stir 0.3-0.5 hour, be cooled to 90- 100 DEG C, add formaldehyde 12-30 part, accelerator hexamethylenetetramine 1-3 part, 90-100 DEG C of stirring 2-2.5 hour of constant temperature, add Tetramethylolmethane 10-15 part, stirring reaction 2-2.5 hour, it is warming up to 270-280 DEG C of evacuation 1 hour；Obtain final product product.
The product of the present invention has lighter color, the features such as softening point is high, is applied to paint, ink, synthetic resin, gluing The industrial departments such as agent, electronics, chemical industry.
Present invention beneficial effect compared with prior art：Rationally, response speed is fast and relaxes it is easy to control for design science System, product color is shallow, up to more than 185 DEG C of softening point, quality are good, the advantages of production cost reduces.
Specific embodiment
Embodiment
The present invention's is raw materials used available commercially.
The modified epoxy preparation method of the present invention it is characterised in that：By weight, 100 parts of epoxy resin, Colophonium 10 Part, 150-160 DEG C of melting of heating, plus bisphenol-A 10-15 part, 180-200 DEG C of intensification, stir 0.3-0.5 hour, be cooled to 90- 100 DEG C, add formaldehyde 12-30 part, accelerator hexamethylenetetramine 1-3 part, 90-100 DEG C of stirring 2-2.5 hour of constant temperature, add Tetramethylolmethane 10-15 part, stirring reaction 2-2.5 hour, it is warming up to 270-280 DEG C of evacuation 1 hour；Obtain final product product.
Products obtained therefrom quality index reaches following index：
