Abstract

The invention provides a green PVC thin film with extremely high anti-mold property, and relates to the technical field of high molecular materials. The green PVC thin film comprises the following rawmaterials in parts by weight: 100 to 120 parts of PVC resin powder, 12 to 18 parts of an anti-mold agent, 5 to 8 parts of a heat stabilizer, 0.8 to 1.3 parts of a plasticizer, 0.3 to 0.5 part of a compatilizer and 0.6 to 0.8 part of a filler; and the anti-mold agent comprises the following raw materials in parts by weight: 2 to 6 parts of o-phenylphenol, 5 to 8 parts of 2-pyridinethiol-1-zinc oxide, 13 to 18 parts of ammonium persulfate, 6 to 11 parts of prochloraz and 9 to 15 parts of sodium benzoate. The green PVC thin film has the beneficial effects that the manufactured PVC thin film haspreferable anti-mold property, the breeding of bacteria is avoided, and the green PVC thin film is beneficial for keeping sanitation.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a green PVC film with extremely high mildew resistance. Background technique [0002] PVC film, the full name is Polyvinylchlorid film, the main component is polyvinyl chloride, and other components are added to enhance its heat resistance, toughness, ductility, etc. The top layer of this surface film is paint, the main component in the middle is polyvinyl chloride, and the bottom layer is back-coated adhesive; PVC film is a synthetic material that is loved, popular and widely used in the world today. Material, the global usage of PVC film ranks second among all kinds of synthetic materials. Among the materials that can produce three-dimensional surface films, PVC is the most suitable material. However, the currently used PVC films generally have the problem of poor mildew resistance, especially for PVC films that need to be stored or used in a humid environment for a...
