Abstract

The invention discloses an antibacterial and softening leather surface treatment agent, and relates to the technical field of leather processing. The antibacterial and softening leather surface treatment agent is prepared from the following raw materials in parts by weight: 20-25 parts of modified rapeseed oil, 5-10 parts of polyoxyethylene, 4-8 parts of polyvinyl alcohol resin, 3-6 parts of hydrogenated rosin pentaerythritol ester, 3-6 parts of microcrystalline wax, 2-4 parts of C9 petroleum resin, 2-4 parts of hydrogenated castor oil, 2-4 parts of gum dammar, 1-2 parts of hexamethylol melamine hexaether, 1-2 parts of nano-glue powder, 1-2 parts of Carbomer resin, 0.5-1 part of sodium tripolyphosphate, 0.5-1 part of asbestos wool, 0.5-1 part of sodium chloride, 0.3-0.5 part of tea seed powder and 0.3-0.5 part of calamine powder. The antibacterial and softening leather surface treatment agent provided by the invention can enter the interior of leather fiber through penetration and form a layer of lubricating oil film on the surface of the fiber so as to make leather texture soft; the antibacterial and softening leather surface treatment agent endows leather with excellent antibacterial performance, so that breeding of mold on the surface of the leather in a wet environment or in a Meiyu rainy season can be prevented.

Description

[0001] Technical field: [0002] The invention relates to the technical field of leather processing, in particular to an antibacterial and soft leather surface treatment agent. [0003] Background technique: [0004] The fundamental reason why the leather is soft is that during tanning, leather imitation oil with a good combination with leather fibers is introduced into the interior of the animal skin to form an oil film that completely covers the surface of the fibers in the leather, that is, between the surfaces of the fibers in the leather, use a Layers of leather with appropriate thickness are separated by simulated oil film, so that the friction force between the fibers inside the leather is equivalent to the friction force of oil molecules, so the leather will be very soft. However, the oil introduced into the leather will slowly volatilize, and the oil film will be hydrolyzed when it meets water or destroyed by high temperature, so that the fibers inside the leather will...
