Abstract

The invention discloses a preparing method for disproportionated rosin potash soap with the solid content of 80%, and relates to the technical field of deeply processing chemical engineering rosin. The preparing method includes the steps that 95-105 parts of solid disproportionated rosin and 55-80 parts of potassium hydroxide solution with the concentration of 20-25% are added into a saponification reactor, heated to the temperature of 80 DEG C-100 DEG C to carry out saponification for 1-2 h first, then added with 0.2 part of hydrogen peroxide and stirred for 0.5 h, and the product is discharged after stirring is stopped to obtain the disproportionated rosin potash soap with the solid content of 80%. The preparing method for the disproportionated rosin potash soap with the solid content of 80% is more stable, safer, more efficient and low in production cost, and the disproportionated rosin potash soap with the solid content of 80% and prepared through the method is light in color.

Description

technical field [0001] The invention relates to the technical field of rosin deep processing, in particular to a preparation method of disproportionated rosin potassium soap with a 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] However, most of the 80% disproportionated rosin potassium soaps with a solid content of 80% disproportionated rosin sold on the market not only have potential safety hazards...
