Inorganic nano leather repairing agent and preparation method thereof

Abstract

The invention discloses an inorganic nano leather repairing agent and a preparation method thereof. The inorganic nano leather repairing agent comprises the following components by weight percent: 30.0-70.0 percent of nano silicon-dioxide particle hybridizationed and modified acrylic resin emulsion, 2 / 0-10.0 percent of polyethyleneimine aqueous solution, 0-6.0 percent of crosslinking agent, 0-2.0 percent of emulsifying agent, 2.0-8.0 percent of solvent, 0.2-0.5 percent of preservative, 3.8-65.5 percent of water. Simultaneously, the invention also provides the preparation method of the repairing agent. The preparation method comprises the following steps of: adding the nano silicon-dioxide particle hybridizationed and modified acrylic resin emulsion into water, dispersing uniformly, then, adding polyethyleneimine aqueous solution, the solvent and the emusifying agent, stirring to be uniform, and then adding the crosslinking agent and the preservative. The inorganic nano leather repairing agent and a preparation method disclosed by the invention have the advantages that the binding of the repairing agent and leather is firm, the elasticity is good after curing, the toughness, the wear resistance and the water resistance are achieved, the modified leather is good in mending and filling effect and is stable and durable in storage.

Description

technical field [0001] The invention relates to a fur care agent and a preparation method thereof, in particular to a leather restoration agent and a preparation method thereof. Background technique [0002] Most of the currently widely used leather surface repair and finishing technologies use polyurethane and acrylic resins to fill the residual parts of the leather after curing. There is also technology to add silica components to enhance the ability to cover disabilities, but the above various repairing technologies still have many defects in practical applications, such as poor filling performance, poor bonding with leather fibers, insufficient water resistance, and UV resistance. , Poor antibacterial properties, weak combination of repair parts, low solid content, must be used repeatedly for repair. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a leather repair agent with better comprehensive performance ...
