Abstract

The invention discloses a release paper coating material for manufacturing heat-storage warm-keeping synthetic leather suitable for clothing, and relates to the technical field of synthetic leather processing. A surface coating agent, a middle coating agent and a subsequent coating agent are used as coating materials of release paper, and a film layer is formed on the release paper by virtue of a synergistic effect of the coating materials, wherein water is used as a solvent for the coating agents, which is safe and nontoxic, and has strong environment-friendliness, so that the problem that an organic solvent is easy to volatize, causes pollution of the environment and is harmful to human health can be avoided; meanwhile, the prepared film layer has good compounding property with synthetic leather base cloth, and can be completely peeled off from the release paper easily; moreover, the prepared film layer, after compounded with the synthetic leather base cloth, can endow the manufactured synthetic leather with excellent heat-storage and warm-keeping properties, and the synthetic leather has moderate elasticity, high strength, and good water resistance and flame retardance, so that the synthetic leather is suitable for clothing processing.

Description

Technical field: [0001] The invention relates to the technical field of synthetic leather processing, in particular to a release paper coating material suitable for making heat-storing and warm-keeping synthetic leather for clothing. Background technique: [0002] At present, leather resources are increasingly scarce and expensive in the clothing leather market. With the development of clothing synthetic leather technology in recent years, synthetic leather is very close to genuine leather in terms of style and feel, and even surpasses genuine leather in some aspects. At the same time, due to the low price and various styles of synthetic leather clothing, synthetic leather clothing has already occupied more than half of the leather clothing market and is favored by consumers. However, the service life of synthetic leather clothing is relatively short, and surface cracks are prone to occur after several years of use, and the warmth retention property drops sharply, thereby s...
