Abstract

The invention provides a PVC (polyvinyl chloride) adhesive film which is used for packing matte plastic-powder baking-finish workpieces and has good water resistance, high viscosity and good atmosphere aging resistance. The PVC adhesive film comprises a PVC film and an adhesive adhering to the PVC film, wherein the adhesive is prepared from raw materials as follows: poly-1,4-butylene adipate glycol, 4,4 methylene diphenyl diisocyanate, triethylamine, dimethylolpropionic acid, butyl acrylate, methyl methacrylate, glycidyl methacrylate, hydroxypropyl acrylate, acyclic acid, N, N-dimethylformamide and potassium peroxodisulfate. The invention further provides a preparation method of the PVC adhesive film. The PVC adhesive film and the preparation method thereof have the benefits as follows: acrylic resin is modified by adopting polyurethane, N, N-dimethylformamide is taken as a medium, glycidyl methacrylate is taken as a cross-linking agent, the prepared adhesive cooperates with the PVC film, and the PVC adhesive film with low water absorption, high adhesive strength and excellent atmosphere aging resistance can be obtained.

Description

technical field [0001] The invention relates to the field of packaging films, in particular to a PVC adhesive film used for packaging sanded and baked varnish workpieces and a preparation method thereof. Background technique [0002] There are two main types of fire doors, one is bright baking varnish, and the other is matt plastic powder baking varnish. Fire doors need to be packed with special packaging film before leaving the factory. PE water-adhesive film is a commonly used packaging film for fire doors with glossy paint, but it is not suitable for fire doors with matt plastic powder paint. The purpose of the product. So now we can only use double-sided tape to paste the PE water film on the fire door, and then pack the fire door with matt plastic powder baking paint in a packaging bag. This packaging method is not only time-consuming and labor-intensive, but also cannot guarantee the packaging. reliability. [0003] The above-mentioned PE water glue film is made by...
