Embodiment 1

[0011] Example 1: Put 500 grams of 80% disproportionated rosin potassium soap into the reaction pot, start heating and stirring, after the temperature reaches 70°C, add 2.5g of decolorizer dropwise, continue stirring for 20 minutes, stop stirring, and cool down to below 50°C The light color solid content of 80% disproportionated rosin potassium soap was obtained as a material.

Embodiment 2

[0012] Example 2: Put 10 kilograms of 80% disproportionated rosin potassium soap into the reaction pot, start heating and stirring, after the temperature reaches 80°C, add 30g of decolorizing agent dropwise, continue stirring for 30 minutes, stop stirring, cool down to below 50°C and discharge Obtain this light color solid content 80% disproportionated rosin potassium soap.

Embodiment 3

[0013] Example 3: Put 100 kilograms of 80% disproportionated rosin potassium soap into the reaction pot, start heating and stirring, after the temperature reaches 90°C, add 200g of decolorizer dropwise, continue stirring for 40 minutes, stop stirring, and cool down to below 50°C for discharge Obtain this light color solid content 80% disproportionated rosin potassium soap.

[0014] The technical index of disproportionated rosin potassium soap with light color solid content of 80% of the present invention is as follows: solid content of 80%, Garner color number≤3, pH (25°C) of 9.7, potassium abietate content of 0%, potassium dehydroabietate content of 48.6% , chloride (calculated as KCl) content of 0.05%, saponified content of 8.2%.

Abstract

The invention discloses a preparation method for light-colour disproportionated rosin potassium soap with a solid content of 80%, which relates to the technical field of rosin deep processing. The preparation method comprises the following steps of adding the disproportionated rosin potassium soap with the solid content of 80% in a reaction container and heating, when the temperature rises to 70-90 DEG C, dripping a decolourant for a decolouration reaction, wherein the decolourant is peroxide K, and the mass percentage of the decolourant to the disproportionated rosin potassium soap with the solid content of 80% is (0.002 to 0.005): 1; stirring for 20-40 minutes; and after stirring, cooling, discharging when the temperature is reduced to be lower than 40 DEG C, so as to obtain the light-colour disproportionated rosin potassium soap with the solid content of 80%. The 1-3 Garner colour numbers of the light-colour disproportionated rosin potassium soap with the solid content of 80% are reduced compared with the Garner colour number of the disproportionated rosin potassium soap with the solid content of 80% and without any colour processing, so that the light-colour disproportionated rosin potassium soap with the solid content of 80% is improved in appearance, the level of the product is increased, and the needs of the market 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 80%. 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 80% disproportionated rosin potassium soaps sold on the market is darker, does not reach the standard of m...
