Abstract
The invention discloses a production method of rosin modified epoxy resin. In the invention, the following raw materials are adopted: epoxy resin, organic coated active titanium dioxide, rosin, 30wt% hydrogen peroxide and 2-amino-2-methyl-1-propyl alcohol. The production method comprises the following steps: putting the epoxy resin, rosin and 2-amino-2-methyl-1-propyl alcohol into a reaction kettle and mixing uniformly; dropwise adding the 30wt% hydrogen peroxide at 80-100 DEG C; after the 30wt% hydrogen peroxide is dropwise added, continuously stirring for 10-30 minutes; adding the organic coated active titanium dioxide while stirring at 50-60 DEG C, and continuously stirring for 30-60 minutes; and filtering, washing and drying the obtained reaction product. In the invention, by adding the organic coated active titanium dioxide, rosin, 30wt% hydrogen peroxide and 2-amino-2-methyl-1-propyl alcohol at certain proportions in the production process, the anti-ultraviolet property of the product is effectively improved.
Description
Technical field
The invention belongs to Colophonium deep process technology field, the production method of a kind of Abietyl modified epoxy resin.
Background technology
Epoxy resin is the organic compound referring to and containing two or more epoxide groups in molecule, and in addition to indivedual, their relative molecular mass is the highest.The molecular structure of epoxy resin is being its feature containing active epoxide group in strand, and epoxide group may be located at the end of strand, centre or structure circlewise.Due in molecular structure containing active epoxide group, make them can crosslink reaction with polytype firming agent and formed and insoluble there is the cancellated high polymer of three-dimensional.In all molecular structures, the macromolecular compound containing epoxide group is referred to as epoxy resin.Epoxy resin after solidification has good physics, chemical property, it has the adhesive strength of excellence to the surface of metal and nonmetallic materials, dielectric properties are good, deformation retract rate is little, product size good stability, and hardness is high, pliability is preferable, to alkali and major part solvent-stable, thus it is widely used in national defence, each department of national economy, pours into a mould, impregnate, be laminated the purposes such as material, bonding agent, coating.But, although epoxy resin exists above-mentioned many merits, but in place of it there is also some shortcomings, epoxy resin its anti-ultraviolet property after using firming agent is poor i.e. mostly, it is impossible to meet the requirement in market.To this end, epoxy resin is generally first modified by people, thus in various degree overcome drawbacks described above.Wherein, epoxy resin carrying out Abietyl modified process is one of which method of modifying.
Summary of the invention
The present invention provides the production method of a kind of Abietyl modified epoxy resin, and the vinsol that the method prepares can overcome the shortcoming that epoxy resin anti-ultraviolet property is poor.
In order to solve above-mentioned technical problem, the technical solution adopted in the present invention is:
Use the raw material of following parts by weight:
Epoxy resin 100 parts, Organic substance peplos active titanium dioxide 1 part～5 parts, Colophonium 20 parts～30 parts, 30wt% hydrogen peroxide 5 parts～8 parts, 2-amino-2-methyl-1-propanol 1 part～5 parts；
Comprise the following steps:
The most first above-mentioned raw materials epoxy resin, Colophonium, 2-amino-2-methyl-1-propanol are put into mix homogeneously in reactor, then at 80 DEG C～100 DEG C, dropping 30wt% hydrogen peroxide while stirring；
B.30wt% after hydrogen peroxide completion of dropwise addition, continue overtime work 10 minutes～30 minutes, then at 50 DEG C～60 DEG C, add Organic substance peplos active titanium dioxide while stirring, and continue to stir 30 minutes～60 minutes；
C. gained product filtered, wash, be dried.
Owing to using technique scheme, there is advantages that
The present invention is by adding a certain proportion of Organic substance peplos active titanium dioxide, Colophonium, 30wt% hydrogen peroxide and 2-amino-2-methyl-1-propanol in its production process, thus effectively improves the anti-ultraviolet property of product.
