Zirconium-aluminum-titanium multi-metal complex powder and preparing method thereof

Abstract

The invention discloses a preparing method of zirconium-aluminium-titanium poly-metallic complex powder, which comprises the following steps: allocating 5-30 wt zirconium sulfate, 40-70 wt aluminum sulfate and 6-40 wt titanic sulfate; dissolving to diverse density solution with density at 0.2-0.5mol / L sulfuric acid water solution separately; mixing; adding into 0.8-30 wt masking agent and 10-50 wtadditive; ripening; spray-drying; getting the product. This product can be used to pig, cattle and sheep leather business and preparation of protein biological medical material, which opens a new approach for modify of protein.

Description

technical field [0001] The invention relates to a zirconium-aluminum-titanium multimetal complex powder and a preparation method thereof. Background technique [0002] In the history of tanning, metal tanning agents and tanning methods are not the oldest. However, due to the excellent performance of metal tanning agents, especially chrome tanning agents, it occupies a dominant position in the modern leather industry. But the serious environmental pollution problem makes people pay more attention to and develop new tanning agents. [0003] There have been many reports and concerns about chrome-free metal tanning agents and cleaning technologies at home and abroad. The Indian Leather Research Center has carried out a series of studies on multi-metal complex tanning agents. For example, Madhan.B. et al. have studied the aluminum-zinc tanning agents formulated with different masking agents and different ratios, and the shrinkage temperature of the leather after tanning.
