Abstract

The invention provides a puncture-resistant PET heat-shrinkable sleeve material and a preparation method thereof. The components contained in the puncture-resistant PET heat-shrinkable sleeve material and their mass percentages are: PET 10%~30%, PETG 10% %~30%, PBT 10%~25%, PEN 20%~35%, PA66 2%~10%, EMA 2%~10%, antioxidant 0.1%~2%. By adopting the technical solution of the invention, the environmental protection PET casing has good shrinkage, good insulation performance, and good mechanical strength and rigidity. Moreover, during the use of the capacitor, the PET sleeve plays a very good role in resisting when it is hit by the capacitance guide needle, so as to achieve the effect of resistance to the puncture of the capacitance guide needle.

Description

technical field [0001] The invention belongs to the technical field of materials, in particular to a puncture-resistant PET heat-shrinkable sleeve material and a preparation method thereof. Background technique [0002] Environmentally friendly PET heat-shrinkable tubing, as an environmentally friendly alternative to PVC heat-shrinkable tubing, can basically replace PVC heat-shrinkable tubing in the heat-shrinkable tubing industry. It can be well coated on the surface of the capacitor through heat shrinkage, which has a good insulation protection effect, and has a good surface appearance with a flat shrinkage. The environmentally friendly PET heat shrinkable sleeve meets the requirements in terms of shrinkage, heat resistance, water resistance and solvent resistance. Safe and reliable to use. [0003] At present, the PET heat shrinkable sleeve is in the development stage. Most of the PET materials used in my country's industrial applications belong to the additive blended m...
