Abstract

The invention relates to the technical field of plastic product preparation, in particular to a preparation method of high-temperature resistance degradable PVC tablecloth. According to the preparation method provided by the invention, a self-crosslinking acrylate emulsion obtained by reaction is prepared into a modified adhesive film, the modified adhesive film is adhered to a PVC film to form athree-layer composite film, and hot pressing is performed on the three-layer composite film to obtain the high-temperature resistance degradable PVC tablecloth; a resin matrix with aluminum powder, aluminum powder filling particles can increase a melting point of the PVC tablecloth and effectively reduce thermoplastic deformation at high temperature, so that the high-temperature resistance performance of the PVC tablecloth is improved; and a self-crosslinking acrylate adhesive film is soaked with a starch glue liquid, and starch is easily decomposed into monosaccharide in the long-term insolation process, so that the effect of degradation to the tablecloth is exerted, and contribution is made to environmental protection.

Description

technical field [0001] The invention relates to the technical field of plastic product preparation, in particular to a method for preparing a high-temperature-resistant degradable PVC tablecloth. Background technique [0002] Tablecloth is an item that is covered on the table or tabletop to prevent dirt or increase the appearance. Also known as: tablecloth, because it is customary to cover the table, so it is also called tablecloth. Due to the usage habits at home and abroad and the specifications of the table, the shapes and names are different. There are square table sets, round table sets, tea table sets, dining table sets, etc. They are mainly used for furnishings, banquets, and meals. They are generally suitable for hotels, teahouses, etc. Sophisticated place. [0003] According to the classification of production process, it can be divided into two types: plastic and textile. Plastics can be divided into: PVC tablecloth, EVA tablecloth, PEVA tablecloth, hot stamping...
