Abstract

The invention discloses a physical property enhanced heat-shrinkable sleeve and a preparation method thereof. Specifically, the heat-shrinkable sleeve disclosed by the invention is prepared from an enhanced PET material irradiated by an electron accelerator; the enhanced PET material comprises the following components in parts by weight: 60-100 parts of PET, 10-30 parts of polyethylene, 12-25 parts of a modified material, 15-30 parts of an inorganic flame retardant, 12-18 parts of a plasticizer, 5-9 parts of a stabilizer, 0.5-5 parts of nano silicon dioxide, 1-8 parts of carbon black and 2-6 parts of a color masterbatch. According to the heat-shrinkable sleeve provided by the invention, the modified material is added into the raw material components, so that the physical properties of theheat-shrinkable sleeve product are improved, the tensile strength of the heat-shrinkable sleeve product is greater than or equal to 30MPa, and the elongation at break is greater than or equal to 540%;meanwhile, the performance of the heat-shrinkable sleeve prepared by adopting the new formula is not reduced at all, the heat-shrinkable sleeve can completely reach the international standard, and the product preparation method is simple, suitable for industrial production and suitable for various fields with special requirements on the heat-shrinkable sleeve.
