Abstract

A high-light release paper for synthetic leather is provided with a multi-functional layer between a substrate and a release layer; the multi-functional layer comprises 30 to 80 parts by weight of inorganic particles, 20 to 80 parts by weight of adhesives, 30 to 80 parts by weight of water, 1 to 8 parts by weight of dispersing agent, and 1 to 5 parts by weight of surfactant; and the forming materials of the release layer comprise alkyd modified silicone resin, melamine resin and acid catalyst. The invention has the advantages of low cost, good performance, excellent re-use performance, and over 70 percent of gloss for the angle of 60 degrees measured according to ISO-2813.

Description

technical field [0001] The invention relates to a paper product, in particular to a release paper for synthetic leather. Background technique [0002] There are many ways to manufacture synthetic leather, and a common one is: coating synthetic leather composition on leather release paper, for example, urethane resin, vinyl chloride resin, polyamide resin, and amino resin etc., make After drying or curing, the composition is coated with an adhesive, pasted with fabric base cloth, etc., and the synthetic leather is obtained by peeling the leather release paper from the synthetic leather composition. The synthetic leather manufactured by this method is to copy the surface state of the leather release paper to the synthetic leather, so it can be obtained by improving the appearance of the leather release paper and increasing the surface gloss of the leather release paper. , high-gloss synthetic leather. [0003] At present, there are many techniques for preparing leather relea...
