Abstract

The invention discloses a production technology of waterborne polyurethane leather for an automobile seat. The production technology comprises steps as follows: (1), release paper is coated with a waterborne composite sizing agent bottom layer and sent to a medium-wave infrared heating dryer to be dried; (2), the waterborne composite sizing agent bottom layer is coated with a waterborne composite sizing agent surface layer, sent to the medium-wave infrared heating dryer to be dried, then attached with a waterborne polyurethane superfine fiber synthetic leather base and dried, and a semi-finished product of the waterborne polyurethane leather for the automobile seat is obtained; (3), a spray agent is sprayed to the waterborne composite sizing agent surface layer in the semi-finished product of the waterborne polyurethane leather for the automobile seat, the semi-finished product is sent to the medium-wave infrared heating dryer to be dried, and the waterborne polyurethane leather for the automobile seat is obtained. The synthetic leather for the automobile seat is produced in combination of a synthetic leather dry-method film transfer technology and a spraying process, the technological steps are simple, environment-friendly and safe, the operability is high, and the obtained leather for the automobile seat has the characteristics of wear resistance, pollution resistance, ultraviolet ray resistance and the like, feels more fine, touches better and is like natural leather.

Description

technical field [0001] The invention relates to the technical field of synthetic leather production, in particular to a production process of water-based polyurethane car seat leather. Background technique [0002] At present, the polyurethane size used for superfine fiber synthetic leather is mainly solvent-based size. The processing technology is mature, among which the technology for car seat leather is all made of solvent into polyurethane dry veneer technology. DMF must be used in the preparation of this kind of synthetic leather. DMF will volatilize after being dried at high temperature during production, and then it needs to be recycled through a recovery device. However, there are still a small amount of unrecoverable solvents that will remain in the product. Many environmentally friendly products now have DMF residues. It is stipulated at 300ppm or even higher, and it is required to be below 30ppm. [0003] Water-based resin uses water as the dispersion medium, ha...
