Abstract

The invention relates to a water-soluble octacarboxyl silsesquioxane tanning agent prepared by mercaptan-alkene click chemistry process and a method thereof. The method comprises the following steps: firstly preparing octavinyl-polyhedral oligomeric silsesquioxane by using vinyl trimethoxy silane through a hydrolysis condensation method, then reacting octavinyl-polyhedral oligomeric silsesquioxane with mercaptoacetic acid under the condition with photoinitiators and irradiation of ultraviolet lamps to obtain the water-soluble octacarboxyl silsesquioxane tanning agent. The water-soluble octacarboxyl silsesquioxane tanning agent is high in yield and high in purity; the reaction process is easy to control and operate; the reaction time is short; the tanning agent has a certain tanning effect; when the tanning agent cooperating with 2% chromium powder is applied to a tanning process of pickled goat skin, the shrinkage temperature of the tanned crust leather is increased by 35 DEG C; the thickening rate reaches about 67%.

Description

technical field

[0001] The invention relates to the technical field of leather tanning agent synthesis, in particular to a water-soluble octacarboxysilsesquioxane tanning agent prepared based on a thiol-ene click chemistry method and a method thereof. Background technique

[0002] With the improvement of people's living standards, leather products have gradually become an indispensable necessity in today's life. Hundreds of leather chemicals are used in the process of leather processing. These materials are very important for obtaining leather with excellent performance. Chemical material with flexibility, high strength, water resistance, heat resistance, corrosion resistance and chemical stability. At present, the tanning agent used in tanning is mainly chrome tanning agent. The comprehensive performance of chrome tanning agent tanning leather is unmatched by other inorganic tanning agents, synthetic tanning agents and vegetable tanning agents. However, with the sudden in...
