Embodiment 1

[0012] Example 1: Put 500 grams of 25% disproportionated rosin potassium soap into the reaction pot, start heating and stirring, after the temperature reaches 60°C, add 1.5g of hydrogen peroxide dropwise, continue stirring for 5 minutes, stop stirring, cool to below 40°C and discharge Obtain this light color solid content 25% disproportionated rosin potassium soap.

Embodiment 2

[0013] 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 hydrogen peroxide dropwise, continue stirring for 8 minutes, stop stirring, cool to below 40 degrees and discharge to obtain This light color solid content 25% disproportionated rosin potassium soap.

Embodiment 3

[0014] 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 hydrogen peroxide dropwise, continue stirring for 10 minutes, stop stirring, cool to below 40 degrees and discharge to obtain This light color solid content 25% disproportionated rosin potassium soap.

[0015] The technical indicators of disproportionated rosin potassium soap with light color solid content of 25% of the present invention are as follows: solid content is 24.8%, Garner color number is ≤2, PH (25 ℃) is 9.8, potassium abietic acid content is 0%, potassium dehydroabietic acid 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 disproportionated rosin potassium soap with the light-color solid content of 25 percent and relates to the technical field of resin deep processing. The preparation method comprises the steps of adding the disproportionated rosin potassium soap with the solid content of 25 percent into a reaction container for heating, increasing the temperature to 60 to 80 DEG C, dropping hydrogen peroxide for a decolorizing reaction, wherein the mass ratio of the hydrogen peroxide to the disproportionated rosin potassium soap with the solid content of 25 percent is (0.003-0.005):1, and then performing agitation for 5 to 10min; after stopping the agitation, reducing the temperature and discharging when the temperature is lower than 40 DEG C to obtain the disproportionated rosin potassium soap with the light-color solid content of 25 percent. The Gardner color number of the disproportionated rosin potassium soap with the light-color solid content of 25 percent disclosed by the invention is 1 to 3 color numbers lower than the Gardner color number of disproportionated rosin potassium soap with the solid content of 25 percent not subjected to any color treatment, thereby the appearance of the disproportionated rosin potassium soap with the light-color solid content of 25 percent disclosed by the invention is improved, and the grade of a product is improved and the market demands are satisfied.

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...
