Abstract
The invention discloses a preparation method of modified polyvinyl acetate resin. The preparation method is characterized by comprising the following steps: heating 100 parts of polyvinyl acetate resin and 10 parts of rosin based on the weight at the temperature of 150 to 160 DEG C for melting, adding 10 to 15 parts of bisphenol A, heating to 180 to 200 DEG C, stirring for 0.3 to 0.5 hour, cooling to 90 to 100 DEG C, adding 12 to 30 parts of formaldehyde and 1 to 3 parts of hexamethylene tetramine serving as a promoter, stirring at the constant temperature of 90 to 100 DEG C for 2 to 2.5 hours, adding 10 to 15 parts of pentaerythritol, stirring for 2 to 2.5 hours, heating to 270 to 280 DEG C, and vacuumizing for 1 hour to obtain a product.
Description
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 modification vinylite preparation is proposed
Method.
The modified vinylite preparation method of the present invention it is characterised in that: by weight, polyvinyl acetate
100 parts of resin, 10 parts of Colophonium, 150-160 DEG C of melting of heating, plus bis-phenol a 10-15 part, 180-200 DEG C of intensification, stir 0.3-
0.5 hour, it is cooled to 90-100 DEG C, add formaldehyde 12-30 part, accelerator hexamethylenetetramine 1-3 part, 90-100 DEG C of constant temperature stirs
Mix 2-2.5 hour, add tetramethylolmethane 10-15 part, stirring reaction 2-2.5 hour, be 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 vinylite preparation method of the present invention it is characterised in that: by weight, polyvinyl acetate
100 parts of resin, 10 parts of Colophonium, 150-160 DEG C of melting of heating, plus bis-phenol a 10-15 part, 180-200 DEG C of intensification, stir 0.3-
0.5 hour, it is cooled to 90-100 DEG C, add formaldehyde 12-30 part, accelerator hexamethylenetetramine 1-3 part, 90-100 DEG C of constant temperature stirs
Mix 2-2.5 hour, add tetramethylolmethane 10-15 part, stirring reaction 2-2.5 hour, be warming up to 270-280 DEG C of evacuation 1 hour；
Obtain final product product.
Products obtained therefrom quality index reaches following index:
