Summary: | A double-layer heat-shrinkable sleeve for insulation protection of a new energy automobile is composed of two layers of materials, the outer layer is a bright orange halogen-free flame-retardant polyester elastomer material, and the inner layer is a halogen-free high-flame-retardant polyolefin material. The double-layer heat-shrinkable sleeve has a heat shrinkable function. The double-layer heat-shrinkable sleeve has the advantages of good oil resistance, wear resistance, tear resistance, softness and flexing resistance of a polyester material and also has the advantages of good insulating property and environment friendliness of a polyolefin material. The invention provides a technical scheme for preparing the double-layer heat-shrinkable sleeve. The prepared bright orange double-layer heat-shrinkable sleeve can be thermally shrunk at the joints of new energy automobile power wires and cables, flexible bus bars and the like to provide an insulation protection effect.
