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 compound synthetic fat-liquoring agent and a preparation method thereof. The compound synthetic fat-liquoring agent is prepared from high-carbon alcohol sulfosuccinate, mineral oil, silicone oil, sulfited lanoline, an emulsifying agent and a stabilizer. The performance of leather can be improved by the aid of the compound synthetic fat-liquoring agent. The method for preparing the compound synthetic fat-liquoring agent comprises the steps as follows: (1) a sulfonating agent solution is added to the high-carbon alcohol sulfosuccinate dropwise at the temperature rangingfrom 70 DEG C to 100 DEG C for reaction for 4-10 h; (2) the solution is cooled to 50 DEG C, the mineral oil, the silicone oil, the sulfited lanoline and the emulsifying agent are added, the solution is stirred for 1-2 h, alkali is added for neutralization, and the pH value is adjusted to range from 7.5 to 8.5; (3) a certain amount of water is added to the solution, then the stabilizer is added, the solution is stirred for 1-2 h, and then the compound synthetic fat-liquoring agent is obtained. The method is relatively simple, the requirement for equipment is not high, and the production cycle is relatively short.

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...
