Problems solved by technology

The process is simple to operate and the production is easy to control, but the surface of the synthetic leather veneered by this process has poor scratch resistance and wear resistance, low cold resistance and hydrolysis resistance, and unsatisfactory durability
Poor control can also lead to stiff, false sticky and other phenomena
[0003] The composite veneer production process of foreign high-grade synthetic leather mostly adopts the two-component aging veneer process for veneer compounding. Although this process can greatly improve the performance of synthetic leather, due to the need for aging and molding, every certain meter of production The products must be cut and then placed in the curing room for curing, resulting in high energy consumption, large floor space, long processing time, high processing costs, less use of release paper, and slow tracking and testing of product physical properties. Disadvantages, the application is greatly restricted

Abstract

The invention provides a two-liquid type quick forming instant peeling synthetic leather composite veneer, which is mainly characterized in that bonding layer resin is added with a quick crosslinker and a crosslinking catalyst, so that the two-component bonding layer resin achieves quick crosslinking, and can achieve proper degree of crosslinking through normal veneering process so as to achieve the aim of instant peeling. The high peeling hydrolysis resistant non-woven fabric polyurethane synthetic leather produced by the process has good physical and mechanical properties such as high peeling strength, tearing strength and bursting strength, bending resistance, low temperature resistance, hydrolysis resistance, acid and alkali resistance and the like.

Description

technical field [0001] The invention belongs to the field of synthetic leather, and in particular relates to a two-component instant peel-off synthetic leather composite veneer. Background technique [0002] At present, the common synthetic leather veneer process in China is a one-component composite veneer process, commonly known as a single-component composite veneer process. The process is simple to operate, and the production is easy to control. However, the surface of the synthetic leather veneered by this process has poor scratch resistance and wear resistance, low cold resistance and hydrolysis resistance, and unsatisfactory durability. Poor control can also lead to stiff, false sticky and other phenomena. [0003] The composite veneer production process of foreign high-grade synthetic leather mostly adopts the two-component aging veneer process for veneer compounding. Although this process has greatly improved the performance of synthetic leather, due to the need fo...
