preparation example Construction

[0019] A preparation method of Zanthoxylum bungeanum oil / hydrotalcite nanocomposite fatliquoring agent, comprising the following specific steps: the following amounts are parts by mass

[0020] Step 1: First, take 250~350 parts of industrial grade Zanthoxylum bungeanum seed oil and add it to a three-necked flask and raise the temperature to 110°C. Then, add 5~7 parts of mixed decolorizing agent (including 15.5% activated carbon and 84.5% activated clay) for constant temperature reaction 25~30 min, after standing still, filter to obtain decolorized pepper seed oil;

[0021] Step 2: First, take 48~52 parts of acetone and 48~52 parts of magnesium aluminum hydrotalcite into a three-necked flask and stir for 25~30 minutes, then wash and centrifuge them with acetone, repeat the washing and centrifugation several times, and obtain acetone after drying. Modified hydrotalcite;

[0022] Step 3: First, take 30~100 parts of the decolorized Zanthoxylum bungeanum seed oil obtained in Step ...

Embodiment 1

[0027] Step 1: First, take 250 parts of industrial-grade Zanthoxylum bungeanum seed oil and add it to a three-necked flask and raise the temperature to 110 °C. Then, add 5 parts of mixed decolorizing agent (including 15.5% activated carbon and 84.5% activated clay) for constant temperature reaction for 30 minutes. After placing, filter to obtain decolorized pepper seed oil;

[0028] Step 2: First, take 45 parts of acetone and 45 parts of magnesium aluminum hydrotalcite into a three-necked flask and stir for 30 minutes, then wash and centrifuge them with acetone, repeat the washing and centrifugation several times, and dry to obtain acetone organically modified hydrotalcite ;

[0029] Step 3: Add 30 parts of the decolorized Zanthoxylum bungeanum seed oil obtained in Step 1 into a three-necked flask, raise the temperature to 70°C, add acetone organically modified hydrotalcite with 6% of the weight of Zanthoxylum bungeanum seed oil, react for 30 minutes, and heat up to 130°C , a...

Abstract

The invention discloses a preparation method for a prickly ash seed oil / modified hydrotalcite nano fat liquoring complex agent. The preparation method solves the problems that in the prior art, the dispersity of hydrotalcite in prickly ash seed oil is poor, and leather subjected to fat liquoring is inflammable. According to the technical scheme, the preparation method comprises the following steps that firstly, decoloration treatment is carried out on THE industrial-grade prickly ash seed oil so as to obtain decolored prickly ash seed oil; then magnesium-aluminum hydrotalcite is organically modified so as to obtain acetone organic modified hydrotalcite; and finally, the decolored prickly ash seed oil and the acetone organic modified hydrotalcite are compounded, and deacidification treatment is carried out so as to obtain the succinic acid ester sulfonated prickly ash seed oil / hydrotalcite nano fat liquoring complex agent. According to the preparation method, the prepared fat liquoringcomplex agent is applied to flame retardancy tests after fat liquoring of the leather, the flame retardancy of a leather sample subjected to fat liquoring is remarkably improved, and the physical andmechanical properties are obviously improved.

Description

technical field [0001] The invention belongs to the field of preparation of flame-retardant fatliquor for leather, in particular to a preparation method of pepper seed oil / modified hydrotalcite nanocomposite fatliquor. technical background [0002] Fatliquor is the most used leather chemical in the leather industry. It is mainly composed of active substances, neutral oils, additives and solvents. Its function is to make the oil in the emulsion penetrate into the crust leather through mechanical action, thereby improving the texture of the crust leather. Excellent softness, endows crust leather with good softness and usability. However, while the leather fatliquor endows the leather with good various properties, due to its relatively low bonding fastness with the leather fiber, it is very easy to migrate to the leather surface during the heating process and directly become a fuel, thus causing the leather to be flammable. (Ling H J, Yang J W, Xiang L, et al. The synthesis an...
