Bionic scale super wear-resistant agent for textile leather

The invention discloses a bionic scale super wear-resistant agent for textile leather, the bionic scale super wear-resistant agent is a silicon dioxide nanosheet grafted water-soluble polysiloxane particle brush, and the bionic scale super wear-resistant agent comprises silicon dioxide nanosheet powder; and the water-soluble polysiloxane is chemically grafted on the surface of the silicon dioxide nanosheet powder. The invention further discloses a preparation method of the silicon dioxide nanosheet. The surface of a silicon dioxide nanosheet is chemically grafted with a particle brush structure of water-soluble polysiloxane, after the super wear-resistant agent is applied, a bionic scale structure can be formed on the surface of textile leather, the textile leather is endowed with excellent wear resistance, glossiness, dry and wet rubbing resistance and flexibility, and the super wear-resistant agent also has excellent adhesive force and waterproof and anti-pollution capacities; meanwhile, the hand feeling of
