Embodiment Construction

[0009] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0010] An environment-friendly, high-whiteness, aging-resistant projection PVC film, its raw materials are as follows by weight percentage: 48-50% polyvinyl chloride resin, 20% dioctyl terephthalate, 2% epoxy soybean oil, 8% filler, Calcium zinc stabilizer 2.5-3%, anti-ultraviolet agent 2%, antioxidant 2%, pigment 0.5%, high whiteness rutile titanium dioxide 14-16%.

[0011] Specifically, the mass ratio of the anti-ultraviolet agent to the antioxidant is 1:1.

[0012] Specifically, the whiteness of the high-whiteness rutile titanium dioxide is not lower than that of magnesium oxide.

[0013] The present invention als...

Abstract

The invention discloses an environmentally-friendly and ageing-proof high whiteness projection PVC film. The environmentally-friendly and ageing-proof high whiteness projection PVC film comprises, byweight, 48-50% of polyvinyl alcohol resin, 20% of dioctyl terephthalate, 2% of epoxidized soybean oil, 8% of a filler, 2.5-3% of a calcium and zinc stabilizer, 2% of an anti-ultraviolet agent, 2% of an antioxidant, 0.5% of a pigment and 14-16% of high-whiteness rutile titanium dioxide. The polyvinyl chloride resin, high-whiteness rutile titanium dioxide, the antioxidant and the anti-ultraviolet agent are used to greatly improve the tensile strength, the shading rate, the whiteness, the ageing-proof performance and the anti-ultraviolet effect of the PVC film.

Description

technical field [0001] The invention belongs to the technical field of novel processing and application of polymer materials, and more specifically relates to an environment-friendly, high-whiteness, anti-aging projection PVC film. Background technique [0002] PVC synthetic film is widely used. General PVC film has poor strength, average shading rate and whiteness, and has no anti-ultraviolet effect, which cannot meet customer requirements and greatly shortens the use time. Contents of the invention [0003] The object of the present invention is to provide an environment-friendly, high-whiteness, aging-resistant projection PVC film to solve the problems raised in the above-mentioned background technology. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] An environment-friendly, high-whiteness, aging-resistant projection PVC film, its raw materials are as follows by weight percentage: 48-50% polyvinyl chlori...
