Problems solved by technology

[0003] Among the heat-shrinkable films produced in the prior art, PVC heat-shrinkable films are widely used and are currently used as more film packaging materials, but the existing PVC heat-shrinkable films do not conform to environmental protection. Therefore, PET heat-shrinkable films are gradually Became popular, PET heat-shrinkable film is a new type of heat-shrinkable packaging material, because it is easy to recycle, non-toxic, tasteless, good mechanical properties, especially in line with environmental protection, polyester (PET) has become a substitute in developed countries An ideal substitute for polyvinyl chloride (PVC) heat-shrinkable film, because the shrinkable film is often suitable for outdoor use, and the UV resistance of the PET heat-shrinkable film currently on the market is not good, after long-term ultraviolet radiation, it will cause PET heat-shrinkable film The performance of the heat shrinkable film is greatly reduced, reducing the life of the PET heat shrinkable film

Abstract

The invention discloses an anti-ultraviolet PET (Polyethylene Terephthalate) thermal shrinkage film and relates to the technical field of novel materials. The anti-ultraviolet PET thermal shrinkage film contains butyl glucoside modified mullite having the mass fraction of 7.52-7.68%, wherein the maleic acid modified nano graphene having the mass fraction of 1.23-1.26% is doped in the butyl glucoside modified mullite. The PET thermal shrinkage film prepared according to the invention has excellent mechanical property, ultraviolet resistance and excellent barrier property.

Description

technical field [0001] The invention belongs to the technical field of film capacitors, and in particular relates to an ultraviolet-resistant PET heat-shrinkable film. Background technique [0002] Heat shrinkable film is used for sales and transportation of various products, and its main function is to stabilize, cover and protect products. The shrink film must have high puncture resistance, good shrinkage and certain shrinkage stress. During shrinkage, the film must not develop holes. [0003] Among the heat-shrinkable films produced in the prior art, PVC heat-shrinkable films are widely used and are currently used as more film packaging materials, but the existing PVC heat-shrinkable films do not conform to environmental protection. Therefore, PET heat-shrinkable films are gradually Became popular, PET heat-shrinkable film is a new type of heat-shrinkable packaging material, because it is easy to recycle, non-toxic, tasteless, good mechanical properties, especially in l...
