Abstract

The invention discloses an iridescent pearlescent leather and a preparation method thereof, belonging to the technical field of leather. The iridescent pearlescent leather of the present invention comprises leather and a coating, and the coating comprises the following components in terms of the mass percentage of the leather: 7-10% of the first coating, 12-15% of the second coating and 12-15% of the third coating 12-15% of the layer, wherein, the third coating, the second coating and the first coating are sequentially coated on the leather. The preparation method of the iridescent pearlescent leather includes the following steps: preparing the coating Material, coating coating material and drying, the surface of the obtained iridescent pearlescent leather has a reflective effect, the tensile strength is as high as 31 MPa in the transverse direction, 33 MPa in the longitudinal direction, and the friction fading reaches level 4. It has strong friction resistance and yellowing resistance. powerful.

Description

technical field [0001] The invention belongs to the technical field of leather, and in particular relates to an iridescent pearlescent leather and a preparation method thereof. Background technique [0002] With the development of society, more and more high-tech products come out, and many advanced products have a glamorous appearance. Leather products are favored by people for their durability. The surface of traditional leather products is wear-resistant and does not fade. However, if the leather surface is made to have a crystal light effect, it is easy to reduce the wear resistance of the leather. [0003] The Chinese invention patent application with the application number 201510782629.0 discloses a leather high-brightness treatment process, which includes the following steps: soak the leather in 5-15% salt water at 30-40°C for 20-40 minutes, and put the leather in the transfer tank after removal. In the drum, add leather brightener at 30-40°C, turn multi-function at ...
