Matte discoloring long-wool printing treatment agent for synthetic leather and preparation method thereof

Abstract

The invention relates to a matte discoloring long-wool printing treatment agent for synthetic leather. The matte discoloring long-wool printing treatment agent is composed of the following components: modified polyurethane resin, toluene, butyl ester, acetone, silica extinction powder, modified siloxane, amino silicone oil, methoxy silicone oil, polyurethane nanofiber and polytetrafluoroethylene wax powder. The invention further relates to a preparation method of the matte discoloring long-wool printing treatment agent. Compared with the traditional matte long-wool leather surface treatment agent, the matte discoloring long-wool printing treatment agent for the synthetic leather is used to process the surface of the synthetic leather to ensure that the surface of the synthetic leather achieves oily and delicate hand feel, excellent waxy feel, unique downy feel and strong discoloring effect.

Description

technical field [0001] The invention relates to a matte color-changing long-hair printing treatment agent for synthetic leather, in particular to a matte color-changing long-hair printing treatment agent for synthetic leather applied to the back-end process of synthetic leather and a preparation method thereof. Background technique [0002] At present, synthetic leather has been widely used in the production of luggage, clothing, footwear and other products. Resin artificial leather (PU leather) has good physical properties, resistance to twists and turns, good softness, high tensile strength, and air permeability, so PU leather is widely used. For the fabric of footwear or the part of the bag that bears the weight. The surface of PU leather often needs to use some surface treatment agents to obtain leather with different performance characteristics. Ironing treatment agent is a variety of commonly used surface treatment agents. Synthetic leather can produce obvious ironing ...
