Abstract

The invention relates to a high temperature resistant release coating material for artificial synthetic leather release paper, and a preparation method and an application thereof. The release coating material is composed of modified urethane acrylate, modified epoxy acrylate, tripropylene glycol diacrylate, trimethylolpropane triacrylate ethoxylate, perfluoromethacrylate and gamma-methylacryloxypropyltrimethylsilane. A method for preparing the high temperature resistant release coating material for the artificial synthetic leather release paper comprises the steps of orderly putting all the components in a container, mixing and stirring so that the solid components are dissolved, and thus obtaining an even and approximately transparent coating. The release paper is clear and vivid in lines; due to the optimization of the formula, the release paper can be caused to be moderate in hardness, good and stable in release property, numerous in repeated use times, and excellent in solvent resistance and high-temperature resistance.

Description

technical field

[0001] The invention relates to the field of synthetic leather manufacturing, in particular to a high-temperature-resistant release coating material for artificial synthetic leather release paper, a preparation method and application thereof. Background technique

[0002] In the production of artificial synthetic leather, the dry method (also known as transfer coating) production process is to apply the coating agent (polyurethane or PVC) on the release paper, form a continuous and uniform film after drying, and then The film is coated with adhesive and laminated with the fabric (or wet-laid bottom), and then dried, the release paper and the leather are peeled off, and the coating agent (including the adhesive layer) film will be transferred from the release paper onto the fabric (or leather). Artificial synthetic leather is mainly polyurethane synthetic leather (PU leather) and polyvinyl chloride artificial leather (PVC leather).
