Abstract
The invention discloses a production method of a rosin derivative for the pigment industry and relates to the technical field of rosin deep processing. The production method comprises the steps of adding alkylphenol disulphide and tannin into rosin, firstly heating to 120 to 150 DEG C, agitating for 0.5h, and then increasing the temperature to 230 to 270 DEG C, agitating for 2 to 6h; then decreasing the temperature to 180 to 200 DEG C, continuously adding tannin, agitating for 1h and discharging the material to obtain the rosin derivative. By adding two batches of tannin for compounding before and after the disproportionation reaction stage of the rosin and by utilizing the high molecular weight of the batches of tannin and the anti-oxidation effect of contained polyphenols, not only can the thermal stability of the product be improved, but also the pigment coloring power can be further improved, the transparency is higher, and the rosin derivative further has the characteristics of nature, environmental friendliness and environmental protection.
Description
Technical field
The present invention relates to rosin deep process technology field, especially a kind of production method of the rosin derivative for pigment industry.
Background technology
Conventional offset printing ink benzidine yellow pigment needs a large amount of interpolation nilox resin or staybelite to obtain high transparency, high tinting strength, pigment with low cost.Nilox resin on the market and staybelite are substantially all manufacture by precious metal palladium carbon catalyzed reaction.Inevitably there is a certain amount of catalyst residue in the product, there is great potential safety hazard in the rosin derivative that this precious metal catalyst obtains, very easily catching fire in production and transportation.Having there is the serious fire much caused because using this kind of rosin in domestic and international pigment industry, suffers heavy losses.Have people to adopt interpolation antioxidant in large quantities to solve above safety issue in some methods improved, but regrettably this method thoroughly can not be dealt with problems, and sacrifice the color development performance of pigment, have impact on the drying property of ink.
Summary of the invention
The invention provides one and can improve pigmenting power further, have higher transparency, also there is the production method of the rosin derivative for pigment industry of natural, green, environmental protection.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
Add in rosin account for rosin total mass 0.1% ~ 1.0% alkyl phenol disulfide and account for rosin total mass 0.1% ~ 0.2% Weibull, first be heated to 120 DEG C ~ 150 DEG C stir 0.5 hour, and then be warming up to 230 DEG C ~ 270 DEG C stirrings 2 hours ~ 6 hours; Then be cooled to 180 DEG C ~ 200 DEG C again, and continue to add account for rosin total mass 0.2% ~ 0.4% Weibull, stir 1 hour, discharging, obtains this rosin derivative.
In technique scheme, scheme can also be more specifically: described alkyl phenol disulfide can be the one in Pentaphen disulphide, p-tert-butylphenol disulphide.
Owing to adopting technique scheme, the present invention has following beneficial effect:
1, the present invention is composite by adding two batches of Weibull before and after the present rosin generation disproportionation reaction stage respectively, utilize the macromolecule of Weibull in batches with the antioxygenation of contained polyphenol, not only can strengthen the thermostability of product, the present invention also can be further made to improve pigmenting power, there is higher transparency, also there is feature that is natural, green, environmental protection.
2, the present invention is mainly used in the industries such as the synthesis of pigment, and be particularly suitable for the benzidine yellow pigment manufacturing high addition, its quality index meets the service requirements of pigment industry.
3, the present invention adopts non-metallic catalyst to replace precious metal palladium C catalyst, solve the safety problem that precious metal palladium C catalyst brings, obtain the rosin derivative of high heat stability, and compared with conventional disproportionation, hydrogenation, can pigmenting power be improved, have higher transparency.
