Abstract

The invention relates to a fold-resistant white plastic film and a preparation method thereof. The fold-resistant white plastic film is prepared from the following components in parts by weight: 18 to 25 parts of bisphenol S-type epoxy resin, 5 to 11 parts of cellulose acetate butyrate, 1 to 3 parts of diaminopropyl polydimethylsiloxane, 0.1 to 2 parts of polymethyl hydrogen siloxane, 0.02 to 0.8 parts of boron trifluoride-dimethylaniline, 0.02 to 0.06 parts of isophorone diamine and 55 to 75 parts of aqueous solution of polyethylene glycol. The invention also provides the preparation method of the fold-resistant white plastic film.

Description

technical field [0001] The invention belongs to the field of film materials, in particular to a folding-resistant white plastic film and a preparation method thereof. Background technique [0002] A film is a thin, flexible, transparent sheet made primarily of plastic, adhesive, rubber, or other materials. The preparation material of the film is usually a polymer, mainly including polyethylene film, polypropylene film, polyvinyl chloride film and polyester film. There are mainly packaging films, breathable films or water-soluble films and films with piezoelectric properties. [0003] Commercially available films are mostly polymer films synthesized from petrochemical materials, which have many problems such as energy consumption and environmental pollution. Therefore, developing a film with simple process and low cost has become a new requirement for the development of the industry. Contents of the invention [0004] The object of the present invention is to provide a fo...
