Abstract

The invention provides an anti-ultraviolet PVC film and a preparation method thereof. The anti-ultraviolet PVC film comprises the following components in parts by weight: 90-100 parts of polyvinyl chloride resin, 0.7-2.8 parts of an antioxidant, 0.1-0.5 part of an ultraviolet light absorber, 1-3 parts of color masterbatch, 0.2-2 parts of chlorinated paraffin, 0.5-1.4 parts of a stabilizer, 20-50 parts of a plasticizer, 2-4 parts of chemical modified oil and 1-2.5 parts of chlorinated polyethylene. The ultraviolet light absorber comprises the following components in parts by weight: 10-20 parts of modified nano titanium dioxide, 30-60 parts of a phase transfer agent and 5-15 parts of an activating agent. According to the anti-ultraviolet PVC film disclosed by the invention, all the components in the raw materials of the anti-ultraviolet PVC film react with one another, so that the ultraviolet barrier property and the stability of the anti-ultraviolet PVC film are improved, the anti-aging effect of the anti-ultraviolet PVC film is realized, and the service lifetime of the anti-ultraviolet PVC film is further prolonged; and the preparation method is simple and can be widely popularized.

Description

technical field [0001] The invention relates to the field of outer packaging films, in particular to an anti-ultraviolet PVC film and a preparation method thereof. Background technique [0002] The main component of PVC is polyvinyl chloride, hereinafter referred to as PVC, which is a polymer material that uses a chlorine atom to replace a hydrogen atom in polyethylene; it is slightly yellow and translucent, shiny, and its transparency is better than polyethylene. , Polypropylene, worse than polystyrene, with different additives, can be divided into soft and hard polyvinyl chloride, soft products are soft and tough, feel sticky, hard products are higher than low density polyethylene, but lower than polypropylene , so whitening will appear at the bends. Among them, hard PVC does not contain softeners, so it is flexible, easy to form, not brittle, non-toxic and pollution-free, and has a long storage time. It is suitable for many industries such as building materials, packagin...
