The invention relates to a preparation method of automobile seat cushion leather with crystal effect, which is characterized in that a certain proportion of cracking resin and high gloss hard wax are introduced into a leather coating intermediate layer, then through a coating and softening process, the cracking resin in the leather intermediate layer cracks under the action of mechanical force in the softening process to form the crystal glittering natural artistic effect, a top light layer is top-coated by polyurethane (top light layer slurry such as polycarbonate-polyether transparent polyurethane elastic resin and the like) with high physical property and transparency, and the crystal glittering natural artistic effect is expressed by transparent top light resin.
The invention introduces leather cracking resin and high gloss hard wax in the intermediate layer (slurry) to be matched with other components, so as to play a good synergistic effect, so that the leather produces a crystal effect after being finished, and the top finish layer adopts polyurethane (top finish slurry of polycarbonate-polyether transparent polyurethane elastic resin and the like) with high physical property and transparency to top coat so as to meet the physical property requirement of the automobile leather.
The preparation method of the automobile seat cushion leather with the crystal effect can enable the automobile seat cushion leather to form rich artistic special effect, and enable the automobile seat cushion leather to have unique characteristics under the stream of the streamline.
The above is only a preferred embodiment of the present invention, and it should be noted that the above preferred embodiment should not be considered as limiting the present invention, and the protection scope of the present invention should be subject to the scope defined by the claims. It will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the spirit and scope of the invention, and these modifications and adaptations should be considered within the scope of the invention.
