Embodiment 1

[0025] At normal temperature and pressure, 30 parts by weight of acetone, 30 parts by weight of xylene, 3 parts by weight of silica matting powder, 3 parts by weight of acrylic fiber, and 15 parts by weight of modified polyurethane resin were put into a 1L reactor. Stir thoroughly for at least 30 minutes, grind, filter, and discard the filter residue; add 1 part by weight of modified silicone to the resulting mixture, and stir evenly at room temperature; then add 18 parts by weight of the remaining modified polyurethane resin, and stir evenly at room temperature After at least 30 minutes until the viscosity is stable, the finished product of the weak solvent velvet scraper treatment agent for synthetic leather without precipitation and slightly brown viscous liquid is obtained.

Abstract

The present invention relates to a weak solvent fluffy scraper treatment agent for synthetic leather, consisting of the following components: modified polyurethane resin, acetone, dimethylbenzene, silicon dioxide matting powder, modified organic silicon and acrylic fiber. The present invention further relates to a preparation method of the weak solvent fluffy scraper treatment agent for synthetic leather. Compared with the existing treatment agent for ordinary synthetic leather, the surface of the synthetic leather, which is treated by the weak solvent fluffy scraper treatment agent for synthetic leather, disclosed by the present invention, has excellent fluffy sense effect, the hair effect can be directly seen by naked eyes, the tender skin touch is unique, the corrosion to the leather surface is not strong, the effects of the original leather surface can be retained to the greatest extent, and the synthetic leather treated by the treatment agent has a unique and comfortable tactile sensation and an excellent comprehensive effect.

Description

technical field [0001] The invention relates to a weak-solvent velvet-feel scraper treatment agent for synthetic leather and a preparation method thereof, in particular to a weak-solvent velvet-feel scraper treatment agent for synthetic leather and a preparation method thereof, which is applied in the post-process of synthetic leather. Background technique [0002] At present, synthetic leather has been widely used in the production of luggage, clothing, footwear and other products. Synthetic leather has the characteristics of good physical properties, resistance to bending, good softness, high tensile strength, and air permeability. Therefore, synthetic leather is widely used in the fabric of footwear or the weight-bearing parts of bags. The surface of synthetic leather often needs to use some surface treatment agents to obtain leather with different performance characteristics. In recent years, as consumers have higher and higher requirements on the color and feel of the ...
