Abstract

The invention relates to a preparation method for a modified camellia oil fatting agent for leather processing. The method comprises the following steps that a, 850-900 parts by mass of camellia oil, 74-148 parts by mass of n-butyl alcohol and 3-7 parts by mass of catalyzers are taken and added into a reactor; and b, reaction is carried out for 2-3 h at 100-120 DEG C, the hydroxyl value in a reaction system is measured, and by the total amount of reactants, when the hydroxyl value is greater than or equal to 65 mg KOH / g, butyl alcohol which is not fully reacted is removed through reduced pressure distillation.

Description

technical field [0001] The invention relates to the technical field of leather chemical production, in particular to a preparation method of a modified camellia oil fatliquor used in leather processing. Background technique [0002] Fatliquor is an important leather chemical in leather processing. Fatliquor can endow leather with plumpness and softness. However, the improvement of the tensile strength and tear strength of leather by fatliquor is generally not very obvious, so the development of new and high-performance leather fatliquor has become one of the research hotspots. [0003] Camellia oil is obtained from the seeds of the Camellia oleifera tree, which is one of the oldest woody edible vegetable oils in China. China is the country with the widest distribution of Camellia plants in the world and the largest production base of camellia oil in the world. At present, camellia oil and its supplementary products have been widely used in industries such as food, chemical ...
