Embodiment 1

[0025] Under normal temperature and pressure, put 30 parts by weight of modified polyurethane resin, 30 parts by weight of DMF, 30 parts by weight of butyl acetate and 5 parts by weight of silica matting powder into a 1L reactor, stir at room temperature for at least 30 minutes and filter , discard the filter residue; add 4 parts by weight of lanolin, 3 parts by weight of polyoxyethylene ether and 3 parts by weight of castor oil in the obtained mixture, stir at room temperature; then add 2 parts by weight of silicone leveling agent and the remaining 10 parts by weight of the modified polyurethane resin was uniformly stirred at room temperature for at least 30 minutes. When the viscosity is stable, filter and discard the filter residue to obtain a clear, slightly yellowish liquid without precipitation, that is, the finished product of the matte-surface strong permeable wet astringent treatment agent for synthetic leather of the present invention.

Abstract

The invention discloses a matte wet and unsmooth feeling treating agent for synthetic leather and a preparation method of the treating agent. The matte wet and unsmooth feeling treating agent for the synthetic leather is formed by the following components: modified polyurethane resin, DMF (Dimethyl Formamide), n-butyl acetate, silicon dioxide extinction powder, wool grease, polyoxyethylene ether, castor oil and an organic silicon flatting agent. Compared with a conventional common matte leather surfactant, the matte wet and unsmooth feeling treating agent for the synthetic leather, disclosed by the invention, can obviously enable the matte extinction effect of the surface of a leather face to be good after treatment of the synthetic leather, so that the leather face has the unique wet and unsmooth wax feeling and the genuine leather effect of the leather face is strong; and the synthetic leather applying the matte wet and unsmooth feeling treating agent has the wet and unsmooth hand feeling and the comprehensive effect is good.

Description

technical field [0001] The invention relates to a surface treatment agent for synthetic leather and a preparation method thereof, in particular to a matte wet astringency treatment agent for synthetic leather used in the back-end process of synthetic leather and a preparation method thereof, belonging to innovative back-end materials and preparation method . Background technique [0002] At present, synthetic leather has been widely used in the production of luggage, clothing, footwear and other products. PU leather has the characteristics of good physical properties, resistance to twists and turns, good softness, high tensile strength, and air permeability. Therefore, PU leather is widely used in the fabrics of footwear or the parts of luggage that bear the weight. The surface of PU leather often needs to use some surface treatment agents to obtain leather with different performance characteristics. [0003] In recent years, as consumers have higher and higher requirement...
