Embodiment 1

[0011] Example 1: Put 500 grams of 25% disproportionated rosin potassium soap into the reaction pot, start heating and stirring, and after the temperature reaches 60°C, add 1.5g of decolorizer dropwise, continue stirring for 5 minutes, stop stirring, and cool down to below 40°C. The material obtains this light color solid content 25% disproportionated rosin potassium soap.

Embodiment 2

[0012] Example 2: Put 10 kilograms of 25% disproportionated rosin potassium soap into the reaction pot, start heating and stirring, after the temperature reaches 70°C, add 40g of decolorizing agent dropwise, continue stirring for 8 minutes, stop stirring, cool down to below 40°C and discharge Obtain this light color solid content 25% disproportionated rosin potassium soap.

Embodiment 3

[0013] Example 3: Put 100 kilograms of 25% disproportionated rosin potassium soap into the reaction pot, start heating and stirring, after the temperature reaches 80°C, add 500g of decolorizing agent dropwise, continue stirring for 10 minutes, stop stirring, cool to below 40°C and discharge Obtain this light color solid content 25% disproportionated rosin potassium soap.

[0014] The technical indicators of the disproportionated rosin potassium soap with light color solid content of 25% of the present invention are as follows: the solid content is 24.8%, the Garner color number is ≤3, the pH (25° C.) is 9.8, the potassium abietate content is 0%, and the potassium dehydroabietate content is 8.7 %, the content of chloride (calculated as KCl) is 0.02%, and the content of saponified matter is 0.02%.

Abstract

The invention discloses a preparation method of light-color disproportionated rosin potash soap with 25% of solid content, relating to the technical field of deep processing of rosin. The method comprises the following steps: adding the disproportionated rosin potash soap with 25% of solid content into a reaction container, and heating; when the temperature rises to 60-80 DEG C, dropwise adding a decolorizing agent for a decolorizing reaction, wherein the decolorizing agent is a peroxide K, and the mass percentage ratio of the decolorizing agent to the disproportionated rosin potash soap with 25% of solid content is (0.003-0.005):1; stirring for 5-10 minutes; after the stirring, cooling; and discharging when the temperature is lower than 40 DEG C to obtain the light-color disproportionated rosin potash soap with 25% of solid content. The Ghana color number of the light-color disproportionated rosin potash soap with 25% of solid content disclosed by the invention is reduced by 1-3 from the Ghana color number of the disproportionated rosin potash soap with 25% of solid content without any color treatment, thus the appearance of the light-color disproportionated rosin potash soap with 25% of solid content is improved, the product grade is improved, and the market needs are met.

Description

technical field [0001] The invention relates to the technical field of rosin deep processing, in particular to a preparation method of disproportionated disproportionated rosin potassium soap with a light-colored solid content of 25%. Background technique [0002] Disproportionated Rosin Potassium Soap is a kind of rosin deep-processed product with large output, mainly used as emulsifier for rubber. In the synthetic rubber industry, polystyrene butadiene rubber, neoprene, nitrile rubber, ABS and styrene-butadiene / nitrile latex all use disproportionated rosin potassium soap as emulsifier. The use of disproportionated rosin as an emulsifier can enhance the cohesive force of rubber, improve the heat resistance, wear resistance and tear resistance, and when mixed with natural rubber, the adhesion performance is greatly improved. [0003] Yet the color of most solid content 25% disproportionated rosin potassium soaps of selling on the market is darker, does not reach the standar...
