Preparation method of large biological functional agent containing active ingredients of navel oranges

Abstract

The invention discloses a preparation method of a large biological functional agent containing active ingredients of navel oranges. The preparation method comprises the following steps: preparing modified palm oil, preparing modified mineral oil, preparing modified cellulose and preparing a fatting agent. When the large biological functional agent containing the navel orange active component is used for fat liquoring of leather, the fog value of the leather can be reduced, and the fog value tested at 100 DEG C for 16 hours by a mass method is 0.43-0.45 mg; the large biological functional agent containing the navel orange active ingredients, prepared by the invention, has good filling performance on the leather fatliquor, and the absorption rate of the fatliquor is 98.3-98.6%; when the large biological functional agent containing the navel orange active component is used for fat liquoring of leather, the tearing strength of the leather can be improved, the original tearing strength of the leather is 61.2 N / mm, and the tearing strength after fat liquoring is 67.5-68.5 N / mm.

Description

technical field [0001] The invention relates to a preparation method of a large biological functional agent containing navel orange active components, and belongs to the technical field of leather fatliquor. Background technique [0002] Fatliquoring (also known as oiling) in leather production is the process of treating leather with grease or fatliquor under certain technological conditions, so that the leather absorbs a certain amount of grease and gives the leather certain physical, mechanical properties and performance. Fatliquoring can make the fibers inside the leather be wrapped by lubricating grease through chemical and physical action, or the surface of the fibers has affinity with a large number of "oily" molecules, balance the surface energy of the leather fibers, and transform the original high-energy surface into a low-energy surface. Increase the mutual mobility between fibers, thereby preventing the leather from hardening and cracking, and making the leather h...

Problems solved by technology

[0004] CN112626292A discloses a low-fogging leather synthetic fatliquor and its preparation method and application. By modifying palm oil and adding high-boiling mineral oil, the fog value of leather can be reduced, and it can be applied to leather such as car interior seats. , but the addition of a large amount of vegetable oil will result in poor light resistance, the addition of mineral oil and vegetable oil can improve the light resistance to a certain extent, but the filling performance of mineral oil is poor, and the strength of the leather after fatliquoring is slightly worse

[0005] In the current prior art, although the low-fogging fatliquoring agent compounded with vegetable oil and mineral oil can achieve a low fogging effect and improve light resistance to a certain extent, it will lead to poor filling of the fatliquoring agent and lead to a loss of leather strength. Low especially the tear strength and tensile strength, currently there are no articles or reports that can address the shortcomings of this type of fatliquor
