Abstract

The embodiment of the invention relates to the technical field of film processing, and particularly discloses an anti-oil stain tablecloth which comprises an anti-stain coating, a transparent film layer, a pressure-sensitive adhesive layer and a PET release film layer, the surface of the transparent film layer is coated with the anti-stain coating, and the anti-stain coating comprises polyurethaneand nano titanium dioxide doped with zinc, fluorine, nitrogen and boron. According to the transparent film layer provided by the invention, polyester polyol, diisocyanate, urethane acrylate, nano silicon dioxide and cellulose acetate butyrate are adopted, and a curing agent, a catalyst, an antioxidant, a chain extender and a stabilizer are used as auxiliary materials, so that the oil stain resistance of the tablecloth can be effectively improved, and oil stains attached to the surface of the tablecloth can be effectively and conveniently cleaned.

Description

technical field [0001] The embodiment of the invention relates to the technical field of film production and processing, in particular to an oil stain-resistant tablecloth. Background technique [0002] A film is a thin, soft, transparent sheet. Made of plastic, adhesive, rubber or other materials. The scientific explanation of thin film is: a 2-dimensional material formed by depositing atoms, molecules or ions on the surface of a substrate. Example: optical film, composite film, superconducting film, polyester film, nylon film, plastic film, etc. Thin films are widely used in electronics, machinery, printing and other industries. Thin film materials refer to thin metal or organic layers with a thickness ranging from a single atom to a few millimeters. However, the film in the prior art has poor oil stain resistance and needs to be discarded after being used once, resulting in a lot of waste. For this reason, we propose an oil stain resistant tablecloth to solve the above...
