Problems solved by technology

[0003] The traditional PVC advertising film is directly exposed to sunlight. Long-term exposure will make the advertising film yellow and become fragile, which will not only affect the advertising effect of the advertisement, but also cause some damage to the surrounding environment if the PVC advertising film is broken.

Abstract

The invention discloses a preparation method of a PVC advertisement film capable of resisting ageing. The specific preparation method of the PVC advertisement film comprises the following steps: adding PVC, a plastifier, a stabilizing agent, calcium carbonate and zeolite to a reaction kettle, performing stirring and mixing for the first time to obtain a premix, reduction the temperature, then adding antimony trioxide, titanium dioxide and epoxy soybean oil to the premix, performing stirring and mixing for the second time to obtain a mixture, sequentially performing banburying, plasticizing androlling shaping on the mixture to obtain a preformed body, and sequentially performing leading and taking, embossing, cooling and reeling on the preformed body so as to obtain the PVC advertisement film. The ageing resistance of the PVC advertisement film is improved, the service life of the PVC advertisement film is prolonged, and the endurance and the effect of advertising are increased.

Description

technical field [0001] The invention relates to the technical field of film production, in particular to a preparation method for an anti-aging PVC advertising film. Background technique [0002] As a kind of advertising consumables, advertising film has been widely used in various advertising display fields. With the development of digital images, its usage is increasing. There are tons of applications. The front of the advertising film is printed with patterns and texts by color inkjet printing, digital printing or traditional ink printing, and the back is coated with adhesive. [0003] The traditional PVC advertising film is directly exposed to sunlight. Long-term exposure will make the advertising film yellow and become fragile, which will not only affect the advertising effect of the advertisement, but also cause some damage to the surrounding environment if the PVC advertising film is broken. Impact. Contents of the invention [0004] The purpose of the present in...
