Abstract
The invention discloses a nano-particle modified polyurethane synthetic leather sizing agent, which comprises the following components according to parts by weight: 15-30 parts of thermoplastic polyurethane, 62-83 parts of N,N-dimethylformamide, 1-2 parts of addition agent, 1-3 parts of color paste and 0.1-3 parts of nano-particles. The finished product of polyurethane synthetic leather made of the nano-particle modified polyurethane synthetic leather sizing agent manufactured by using the invention is good in abrasive resistance and water vapor permeability.
Description
Technical field
The present invention relates to the Synthetic Leather Material Field, specifically is a kind of nanometer particle-modified Synthetic Leather slurry.
Background technology
Synthetic Leather has soft, the nature of gloss, and soft, kishke feel is strong, and anti-deflection, the excellent characteristics such as anti-aging are the ideal substitutes of natural leather, are widely used in the industries such as clothes, shoemaking, case and bag, furniture; But Synthetic Leather in the market is too large with the natural leather gap aspect water vapour permeability, wear resistance, the poor Synthetic Leather goods of water vapour permeability can make us feeling sultry, clammy, for these shortcomings, mainly improve by the performance that changes the Synthetic Leather slurry at present, but the technique that changes in the market Synthetic Leather slurry water vapour permeability and wear resistance is complicated, cost is higher, and effect is also not too obvious.
Summary of the invention
Technical problem to be solved by this invention is to overcome the shortcoming of above prior art: the slurry that provide that a kind of cost is low, technique is simple, can effectively strengthen Synthetic Leather water vapour permeability and wear resistance.
Technical solution of the present invention is as follows:
A kind of nanometer particle-modified Synthetic Leather slurry, it is comprised of the component of following weight proportion: thermoplastic polyurethane 15-30 part, DMF 62-83 part, auxiliary agent 1-2 part, mill base 1-3 part, nanoparticle 0.1-3 part.
Described auxiliary agent is a kind of in commercially available aerosol-OT salt, the dimethyl silicone oil or their mixture.
Described nanoparticle is a kind of in commercially available nano silicon, polynite, the nano-cellulose.
Described polynite is a kind of in commercially available original montmorillonoid soil, amino acid modified montmorillonite, alkyl quaternary ammonium salts modified montmorillonoid and the silane coupler modified polynite.
Described alkyl quaternary ammonium salts modified montmorillonoid is octadecyl trimethyl ammonium chloride modified montmorillonoid or palmityl trimethyl ammonium chloride modified montmorillonoid.
A kind of preparation method of nanometer particle-modified Synthetic Leather slurry is as follows:
First commercially available DMF, auxiliary agent, mill base and nanoparticle are placed in the agitator and stirred 5-10 minute, and then add commercially available thermoplastic polyurethane, such as thermoplastic polyurethane SW-2020RH, continue stirring and got final product in 20-30 minute.
The invention has the beneficial effects as follows: the method Effective Raise of the present invention by directly in the Synthetic Leather slurry, adding nanoparticle wear resistance and the water vapour permeability of Synthetic Leather finished product, and have that cost is low, technique is simple, be beneficial to the advantage of suitability for industrialized production.
