Abstract

The invention relates to an anti-static PVC (polyvinyl chloride) film vehicle body sticker which comprises an anti-static PVC film, a pressure-sensitive adhesive layer and a release paper layer from top to bottom. The anti-static PVC film is prepared from the following components in parts by weight: 100 parts of polyvinyl chloride resin powder, 20-30 parts of a diisononyl phthalate (DINP) plasticizer, 1-3 parts of epoxidized soybean oil, 2-4 parts of a stabilizer, 9-11 parts of rutile titanium dioxide, 7-9 parts of heavy calcium carbonate, 11-13 parts of light nano-calcium, 1-3 parts of an anti-static agent, 0-2 parts of a processing aid and the balance of pigment. The surface resistivity of the anti-static PVC film vehicle body sticker is lower than 10<9> omega / cm<2>, and static electricity is not prone to being accumulated on the surface of the anti-static PVC film vehicle body sticker. Dust is not prone to being adsorbed. Ink drops are not sputtered due to static electricity during jet drawing printing, and the precision of a jet drawing picture is high. The anti-static PVC film vehicle body sticker is firmly pasted. After the film is stored in an environment of 65 DEG C for 72 hours, a stripping force test shows that the stripping force value is higher than 6N / 25mm.

Description

technical field [0001] The invention relates to the field of body stickers, in particular to an antistatic PVC film body sticker. Background technique [0002] The body stickers referred to in the present invention refer to a class of products composed of PVC calendered film, pressure-sensitive adhesive, and release paper in sequence, wherein the PVC calendered film is composed of polyvinyl chloride resin powder, plasticizer, filler, stabilizer, Additives and other ingredients, prepared by calendering process, PVC calendered film has the characteristics of fast absorption of solvent and binding pigment (such as ink), so it has good printing and inkjet function, often used in digital inkjet advertising materials, widely used in Buses, taxis, subway exhibition halls, shopping malls and other transportation facilities and public places play the role of advertising. [0003] At present, the surface resistivity of PVC film is usually in the range of 10 10 -10 20 Ω / cm 2 , Its ...
