Abstract
The invention discloses a method for directly preparing disproportionated rosin potassium soap with the solid content of 80 percent from solid disproportionated rosin, and relates to the technical field of deep processing of chemical rosin. The method comprises the following steps: adding 95-105 parts of solid disproportionated rosin and 55-80 parts of potassium hydroxide solution with concentration of 20-25 percent into a saponification reaction kettle; heating to 80-100 DEG C to perform a saponification reaction for 1-2 hours while uniformly stirring; cooling to 70-80 DEG C after the saponification reaction is finished; and discharging to obtain the finished product. Compared with the prior art, the method has the advantages of more stable, safer and more efficient preparation process; the disproportionated rosin potassium soap as a finished product is lighter in color and better in quality.
Description
Technical field
The present invention relates to rosin deep process technology field, especially a kind of solid nilox resin directly prepares the method for solid content 80% disproportionated rosin potassium soap.
Background technology
Disproportionated rosin potassium soap is the larger kind of output in the rosin deep processed product, is mainly the emulsifying agent as rubber.In China Synthetic Rubber Industry, emulsion polymerized styrene butadiene rubber, chloroprene rubber, paracril, ABS and butylbenzene/nitrile rubber are all made emulsifying agent with disproportionated rosin potassium soap.Use nilox resin to make emulsifying agent and can make the cohesive force of rubber strengthen, high-temperature capability improves, and abrasion strength resistance and tearing toughness are good, and when mixing with natural rubber, adhesiveproperties has greatly improved.
At present, the method that most of producers prepare disproportionated rosin potassium soap is first by the nilox resin high-temperature digestion, by a certain percentage potassium hydroxide solution, nilox resin liquid, water are slowly passed in reactor and mix again, wherein, require potassium hydroxide solution and nilox resin liquid to add reactor in strict accordance with certain ratio, and the rate requirement added is the same, adition process needs constantly to stir.Adopt this method to prepare disproportionated rosin potassium soap and have a lot of problems, in reality, be difficult to control well potassium hydroxide solution and nilox resin liquid add-on and add speed, even use volume pump also not all right.Once do not control well potassium hydroxide solution and nilox resin liquid add-on and add speed, no matter be that potassium hydroxide solution is excessive or nilox resin liquid is excessive in reactor, so whole preparation process failure, now high vibration can occur in reactor, damage equipment not only, material in reactor all caking becomes waste product, has not only improved production cost, has brought great difficulty also to the follow-up cleaning of reactor.
Summary of the invention
The invention provides a kind of method that preparation process is more stable, safe, efficient solid nilox resin directly prepares solid content 80% disproportionated rosin potassium soap.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
The potassium hydroxide solution of 95～105 parts of solid nilox resins, 55～80 part of 20%～25%% concentration is added in the saponification reaction still, be heated to 80 ℃～100 ℃ and carry out 1～2 hour saponification reaction, saponification reaction stops rear discharging, obtains this solid content 80% disproportionated rosin potassium soap.
In technique scheme, scheme can also be more specifically:
Scheme 1 is added to the potassium hydroxide solution of 95 parts of solid nilox resins, 55 part of 25% concentration in the saponification reaction still, is heated to 80 ℃ and carries out 1 hour saponification reaction, and saponification reaction stops rear discharging, obtains this solid content 80% disproportionated rosin potassium soap.
Scheme 2 is added to the potassium hydroxide solution of 100 parts of solid nilox resins, 65 part of 22.5% concentration in the saponification reaction still, is heated to 90 ℃ and carries out 1.5 hours saponification reactions, and saponification reaction stops rear discharging, obtains this solid content 80% disproportionated rosin potassium soap.
Scheme 3 is added to the potassium hydroxide solution of 105 parts of solid nilox resins, 80 part of 20% concentration in the saponification reaction still, is heated to 100 ℃ and carries out 2 hours saponification reactions, and saponification reaction stops rear discharging, obtains this solid content 80% disproportionated rosin potassium soap.
Owing to adopting technique scheme, the present invention has following beneficial effect:
1, shorten the saponification reaction time, the time of 1/3rd before being;
2, reduce operation easier, only needed general technician can complete alone whole preparation process;
3, more stable, safety, efficient, thus the success ratio of preparation improved, reduced production cost;
4, the color of product is more shallow, better quality.
