Problems solved by technology

However, this type of product has poor stability, is easy to delaminate in summer, and has poor degradability
Although there are reports on the preparation of polymer fatliquors by copolymerizing vegetable oils with high iodine value as hydrophobic monomers and vinyl monomers containing carboxyl groups, the age of such products is relatively poor, mainly because vegetable oils Most of the double bonds are non-conjugated

Example Embodiment

[0032] Example 1:

[0033] The following are all parts by mass

[0034] Step 1: Preparation of epoxy jatropha oil

[0035] Add 50 parts of jatropha oil, 9 parts of glacial acetic acid, and 0.75 parts of concentrated sulfuric acid into a 250ml three-necked flask and mix uniformly. The temperature is raised to 30℃. 40 parts of hydrogen peroxide are added dropwise to the three-necked flask. React at 60° C. for 6 hours. After the reaction is completed, it is cooled to room temperature to remove water, and washed with water to neutrality to obtain epoxy jatropha oil.

[0036] Step 2: Preparation of acrylated Jatropha oil

[0037] Add the reaction product epoxy jatropha oil from step one into a 250ml three-necked flask, add 0.5 part of p-toluenesulfonic acid as a catalyst, add 0.1 part of hydroquinone as a polymerization inhibitor, take 15 parts of acrylic acid and slowly add dropwise Into a three-necked flask, drip 0.5h and react at 60°C for 3h to obtain acrylated Jatropha oil.

Abstract

The invention relates to a preparation method of a jatropha carcass oil base polymer fatting agent. The preparation method comprises the following steps: a, performing epoxidation on jatropha carcassoil by using hydrogen peroxide, glacial acetic acid and concentrated sulfuric acid so as to obtain epoxy jatropha carcass oil; b, by taking sodium p-toluenesulfonate as a catalyst, hydroquinone as a polymerization inhibitor, and acrylic acid as a nucleophilic reagent, performing a ring-opening reaction on the epoxy jatropha carcass oil so as to obtain acrylic acid esterified jatropha carcass oil,and introducing an active vinyl part to a plant oil molecular chain; and c, by taking 2,2'-azobis(2-methylpropionitrile) as a catalyst, and acetanilide as an anti-gel agent, adding maleic anhydride, acrylic acid and acrylic acid esterified jatropha carcass oil, and performing copolymerization, thereby obtaining the jatropha carcass oil base polymer fatting agent. Based on natural plant oil which is cheap and easily available as a raw material, the prepared polymer fatting agent is relatively good in cold water emulsification property and good in hydrophilcity, and is an environment-friendly and degradable fatting material.

Description

technical field [0001] The invention belongs to the technical field of leather chemical production, and in particular relates to a jatropha oil-based polymer fatliquoring agent and a preparation method thereof. Background technique [0002] Fatliquor is an important leather chemical in leather processing. Fatliquor can give leather a soft feel. Polymer fatliquor is a resinous fatliquor with amphiphilic structure. It has both It has a certain retanning effect, has a strong binding ability with leather, and has excellent waterproof performance. However, most of the petroleum-based polymer fatliquor products are currently used, which have poor degradability and cause serious pollution to the environment. With the depletion of petroleum resources, it is imminent to find alternative raw materials that are green and environmentally friendly. [0003] Jatropha curcas is planted in large quantities in the mountainous areas of southwest my country, and it has strong survival ability...
