Embodiment 1

[0022] Add 100g of C16-18 alcohol into a four-necked glass flask equipped with a stirrer, a thermometer and a condenser, raise the temperature to 75°C, add 25g of maleic anhydride after melting, and react for 2.5 hours to obtain C16-18 alcohol succinate, then 100 g of sodium sulfite solution was added dropwise therein, and the reaction was incubated for 5 hours to obtain C16-18 alcohol sulfosuccinate. Cool down to 50°C, then add 120g of 10# white oil, 20g of simethicone oil with a viscosity of 500cp, 75g of sulfited lanolin, and 35g of emulsifier, stir well for 1 to 2 hours, then add triethanolamine for neutralization, Adjust the pH of the system to 7.5-8.5 by adding water to adjust the water content≦50%, then add 6g of isobutanol and continue stirring for 1 hour to obtain about 957 grams of compound synthetic fatliquoring agent.

Embodiment 2

[0024] Add 100g of C16-18 alcohol into a four-necked glass flask equipped with a stirrer, a thermometer and a condenser, heat up to 75°C, add 27g of maleic anhydride after melting, and react for 3 hours to obtain C16-18 alcohol succinate, then 105 g of sodium metabisulfite solution was added dropwise thereto, and the reaction was incubated for 4 hours to obtain C16-18 alcohol sulfosuccinate. Cool down to 50°C, then add 100g of 10# white oil, 16g of simethicone oil with a viscosity of 1000cp, 80g of sulfited lanolin, and 36g of emulsifier, stir well for 1 to 2 hours, then add 30% liquid subtraction to carry out Neutralize, adjust the pH of the system to 7.5-8.5, add water, adjust the water content to 50%, then add 5g of isopropanol and continue stirring for 1 hour to obtain about 933 grams of compound synthetic fatliquoring agent.

Embodiment 3

[0026] Add 100g of C20 alcohol into a four-necked glass flask equipped with a stirrer, a thermometer and a condenser, raise the temperature to 75°C, add 21g of maleic anhydride after melting, and react for 3 hours to obtain C20 alcohol succinate, and then add it dropwise 100g of sodium metabisulfite solution was incubated for 5 hours to obtain C20 alcohol sulfosuccinate. Cool down to 50°C, then add 100g of 5# white oil, 18g of simethicone oil with a viscosity of 100cp, 70g of sulfited lanolin, and 37g of emulsifier, stir well for 1 to 2 hours, then add ethanolamine for neutralization, adjust The pH value of the system is 7.5-8.5, add water to adjust the water content≦50%, then add 6g of isobutanol and continue stirring for 1 hour to obtain about 898 grams of compound synthetic fatliquoring agent.

Abstract

The invention provides a composite synthetic fat liquor and a preparation method thereof. The composite synthetic fat liquor consists of high-alcohol disodium laureth sulfosuccinate, mineral oil, silicon oil, sulfited lanolin leather fat, an emulsifier and a stabilizer. The composite synthetic fat liquor of the invention can improve the performance of leather. The method for preparing the composite synthetic fat liquor comprises the following steps: (1) dripping solution of sulfonating agent into the high-alcohol disodium laureth sulfosuccinate for reaction for 4 to 10 hours at 70 to 100 DEG C; (2) cooling the solution obtained by the step (1) to 50 DEG C, adding the mineral oil, the silicon oil, the sulfited lanolin leather fat and the emulsifier, stirring the solution for 1 to 2 hours, adding an alkali into the solution for neutralization, and adjusting the pH value of the solution to 7.5 to 8.5; and (3) adding a certain amount of water into the solution obtained by the step (2), adding the stabilizer and stirring the solution for 1 to 2 hours to obtain the composite synthetic fat liquor. The method is simple, low in requirement on equipment and short in production period.

Description

technical field [0001] The present invention relates to a kind of fatliquoring agent and its preparation method, more specifically, the present invention relates to a kind of composite synthetic fatliquoring agent and its preparation method. Background technique [0002] Fatliquor is the most used leather chemical material in leather production, and it is also one of the important chemical materials in leather processing. It can not only lubricate the leather fiber, prevent the leather from being stiff and cracking, but also make the leather have corresponding toughness and softness, and maintain its strength. It can be said that fatliquor is one of the important factors affecting the quality and performance of leather. In the tanning industry, synthetic fatliquor has been valued and favored by people for its excellent fatliquoring effect, and its type and quantity are also increasing year by year, and it has always been a high-grade fatliquoring agent. The molecular struct...
