Abstract

The invention belongs to the technical field of transparent film materials, and particularly relates to an outdoor PVC transparent film. The outdoor PVC transparent film is prepared from the followingraw materials in parts by weight: 90-120 parts of PVC resin powder, 10-15 parts of nano powder, 1-3 parts of methyltin, 2-4 parts of plasticizer, 4-7 parts of an impact modifier, 1-3 parts of a gelling agent, 0.3-1 part of an ink absorbent, 1-3 parts of an antistatic agent, 8-15 parts of titanium dioxide and 3-8 parts of a plastic anti-wrinkle agent. The outdoor PVC transparent film and the preparation method have the beneficial effects that the raw materials are easy to obtain; and the film has good antistatic property and stability, can still maintain good mechanical properties in a high-temperature environment for a long time, is not prone to embrittlement and fragility, and is long in service life.

Description

technical field [0001] The invention relates to an outdoor PVC transparent film and a preparation method thereof, belonging to the technical field of transparent film materials. Background technique [0002] Polyvinyl chloride, referred to as PVC in English (Polyvinyl chloride polymer = PVC molecular structure), is a thermoplastic resin polymerized by vinyl chloride under the action of an initiator. It is a homopolymer of vinyl chloride. Vinyl chloride homopolymers and vinyl chloride copolymers are collectively referred to as vinyl chloride resins. The consumption of PVC in the field of PVC film ranks third, accounting for about 10%. After PVC and additives are mixed and plasticized, a transparent or colored film of specified thickness is made by using a three-roller or four-roller calender, and the film is processed by this method to become a calendered film. Packaging bags, raincoats, tablecloths, curtains, inflatable toys, etc. can also be processed by cutting and heat...
