Embodiment Construction

[0018] In order to make the purpose and features of the present invention more comprehensible, the specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings.

[0019] See figure 1 , which is a schematic cross-sectional structure diagram of a heat-shrinkable tube provided by an embodiment of the present invention.

[0020] Axial shrinkage rate: (length L2 of heat-shrinkable empty tube after heating and shrinkage - length L2 before shrinkage) / length L2 before shrinkage × 100%.

[0021] The inner wall 110 of the heat-shrinkable tube is provided with grooves 120 extending axially through it.

[0022] In the embodiment of the present invention, please refer to figure 2 , the cross section of the groove 210 is helical, square, zigzag or circular arc.

[0023] In an embodiment of the present invention, the grooves are evenly distributed on the inner wall.

[0024] In the embodiment of the present inve...

Abstract

The invention discloses a heat shrink tube and a manufacturing method of the heat shrink tube, wherein the heat shrink tube has a -10%-40% of axial shrinking percentage, and grooves which penetrate through in an axial direction are distributed on the inner wall of the heat shrink tube. The heat shrink tube has the special axial shrinking percentage and the grooves which penetrate through in the axial direction are distributed on the inner wall. When objects which are covered are irregular in shapes or are with big bending angles, the heat shrink tube can be tightly attached to the objects which are covered, and shrink fold and bulge problems are effectively solved.

Description

technical field [0001] The invention relates to the technical field of polymer materials, and in particular to a heat-shrinkable tube and a manufacturing method thereof. Background technique [0002] Today, heat shrinkable tubes are widely used in the field of electronic power technology. The heat-shrinkable tube is an alloy of polyolefin and its polymer that is cross-linked by radiation. After being irradiated by high-energy rays, it produces a "shape memory" effect, and then achieves the purpose of covering various wires and cable joints, and mentioning the purpose of insulation protection. [0003] The use of heat shrinkable tubes has spread to various products through the continuous development of human beings. For example, the condensing tube of the air conditioner evaporator is covered with a heat-shrinkable tube, which can prevent corrosion and insulate. The outer layer of the rubber tube of the car uses a heat-shrinkable tube for insulation protection and can be sha...
