The present invention relates to an organic silicon synthetic leather and a preparation method therefor. The organic silicon synthetic leather comprises a surface adhesive layer, a bottom adhesive layer and a base layer that are overlaid in sequence; the preparation materials of the surface adhesive layer mainly comprise organic polysiloxane, organic hydrogenated polysiloxane, a vinyl MTQ silicon resin and a spherical vinyl MQ silicon resin, which are mixed at an appropriate ratio to obtain a surface adhesive; the preparation materials of the bottom adhesive layer mainly comprise organic polysiloxane, organic hydrogenated polysiloxane and a vinyl MTQ silicon resin, which are mixed at an appropriate ratio to obtain a bottom adhesive; the surface adhesive is coated on a release paper, the bottom adhesive is coated on the cured surface adhesive after the coated surface adhesive is cured so as to form the bottom adhesive layer, the bottom adhesive layer is composited with the base layer, the composited bottom adhesive layer is cured, and the release paper is removed to obtain an organic silicon synthetic leather. The organic silicon synthetic leather of the present invention is extremely safe, and has excellent abrasive resistance, stain resistance and flame resistance. The preparation method for an organic silicon synthetic leather as described in the present invention is simple and does not use a solvent during preparation. |
