preparation example Construction

[0023] The invention provides a preparation method of succinate sulfonated Zanthoxylum bungeanum seed oil / nano-hydrotalcite composite flame-retardant fatliquor, which is characterized in that it comprises the following steps: the following are parts by mass,

[0024] Step 1: Take 93.5-97.4 parts of crude Zanthoxylum bungeanum seed oil, add 3.8-6.5 parts of mixed decolorizing agent into a three-necked flask, stir for 30 minutes, let it stand for 5-8 hours, and filter it with a 200-mesh filter to obtain decolorized Zanthoxylum bungeanum seed oil;

[0025] Take 90.1~93.2 parts of the decolorized Zanthoxylum bungeanum seed oil, 3.4~4.4 parts of glycerin, add them into a three-necked flask, add 1.5~2.0 parts of concentrated sulfuric acid as a catalyst, heat up to 130°C, react for 3.5~5.5 hours, cool down to 70°C and add 3.1~4.2 parts of methanol, reacted for 2.5~3.5 hours to obtain acid-reduced Zanthoxylum bungeanum seed oil;

[0026] Step 2: Take 1.1~1.3 parts of stearic acid, 0.1...

Embodiment 1

[0034] Put 50g of crude Zanthoxylum bungeanum seed oil into a three-necked flask, add 2.60g of decolorizing agent, stir at 110°C for 30min, and filter through a 200-mesh filter at rest to obtain decolorized Zanthoxylum bungeanum seed oil; take 45g of decolorized Zanthoxylum bungeanum seed oil into a three-necked flask, add 1.83 G glycerin and 0.73g concentrated sulfuric acid were reacted at 130°C for 3h, cooled to 70°C and added with 1.76g methanol, and reacted for 3h to obtain acid-reduced Zanthoxylum bungeanum seed oil;

[0035] Take 150g of deionized water into a three-necked flask, add 2g of stearic acid and 0.24g of NaOH, stir at 45°C for 30 min, adjust the pH to 7.5, add 2g of hydrotalcite and lower the temperature to 25°C, react for 24 hours, centrifuge, wash three times and dry to obtain 2.4 g stearic acid-hydrotalcite.

[0036] Take 49g of Zanthoxylum bungeanum seed oil after acid reduction and decolorization, heat up to 75°C, add 2.4g of stearic acid-hydrotalcite and...

Embodiment 2

[0038] Put 60g of crude Zanthoxylum bungeanum seed oil into a three-necked flask, add 3.13g of decolorizing agent, stir at 110°C for 30min, and filter through a 200-mesh filter to obtain decolorized Zanthoxylum bungeanum seed oil; take 50g of decolorized Zanthoxylum bungeanum seed oil into a three-necked flask, add 2.04 G glycerin and 0.81g concentrated sulfuric acid were reacted at 130°C for 3h, cooled to 70°C and 1.96g methanol was added, and reacted for 3h to obtain acid-reduced Zanthoxylum bungeanum seed oil;

[0039] Take 260g of deionized water into a three-necked flask, add 3.5g of stearic acid and 0.41g of NaOH, stir at 45°C for 30 minutes, adjust the pH to 7.5, add 3.42g of hydrotalcite and cool down to 25°C for 24 hours, centrifuge, wash three times and dry to obtain 4.1 g stearic acid-hydrotalcite.

[0040]Take 54g of Zanthoxylum bungeanum seed oil after acid reduction and decolorization, heat up to 75°C, add 4.1g of stearic acid-hydrotalcite and stir for 30 minutes...

Abstract

The invention mainly aims at providing a succinate sulfated pepper seed oil / nano-hydrotalcite composite flame-retardant fatting agent and a preparing method thereof. At present, the yield of peppers in China is huge, however, pepper seeds serving as main byproducts are not reasonably used, a large number of pepper seeds are incinerated or buried in the field as waste, resources are greatly wasted,and the environment is polluted. A new application field of pepper seed oil is developed, due to the characteristics of the pepper seed oil, after the succinate sulfated pepper seed oil / nano-hydrotalcite composite flame-retardant fatting agent is used for fatting, the antibacterial property of fatted leather can be improved to a certain degree; due to the fact that nano LDH is led in, the appearance of the product can be improved to be yellow from dark brown; and in addition, due to the nano small-size effect of the LDH, the mechanical property of the fatted leather is improved to a certain degree.

Description

technical field [0001] The invention belongs to the technical field of flame-retardant fatliquor, and relates to a succinate sulfonated prickly ash seed oil / nanometer hydrotalcite composite flame-retardant fatliquor and a preparation method thereof. Background technique [0002] Zanthoxylum bungeanum is an important condiment and oil plant in my country, mainly distributed in Sichuan, Chongqing, Shaanxi and other regions. According to reports, my country's annual output of peppercorns is 1 million tons, and pepper seeds are the main by-product, which theoretically exceeds the peel by about 20%. Therefore, the annual output of pepper seeds is about 600,000 tons, and the output cannot be underestimated. The chemical composition of 8 different kinds of Zanthoxylum bungeanum seeds was analyzed, and the results showed that the average oil content was higher than 23%, which indicated that Zanthoxylum bungeanum seeds had high oil content and development value. [0003] However, in...
