Preparation method for prickly ash seed oil/modified hydrotalcite nano fat liquoring complex agent

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.
