Abstract
The invention relates to a heat-seal type heat shrinking sleeve. The section of the heat-seal type heat shrinking sleeve is of annular structure. The annular structure comprises a base layer and a fuse layer, the base layer is arranged outside the fuse layer, and a base and fuse connecting layer is arranged between the base layer and the fuse layer. The annular structure further comprises a base end outer layer and a base end inner layer, and a base connecting layer is arranged between the base end outer layer and the base end inner layer. The heat-seal type heat shrinking sleeve is reasonable in structure and has high shrinking percentage.
Description
Technical field
The invention belongs to plastic products technology field, be specifically related to a kind of heat seal type heat shrinkage sleeve.
Background technique
Middle and later periods nineties oil and gas industry starts to apply heat-shrinking plastics material, is extended to the field such as city gas pipeline, water supply pipe afterwards.The equipment of current production shrink belt is relatively backward technically, have impact on the structure of thermal shrinkage product, affects the quality of thermal shrinkage product, constrains the development of industry.The heat-shrinkable article that prior art is produced, relies on when producing PE base material and forms stretching, gluing after x ray irradiation x, because automatization level is low, cannot be formed and accurately control shrinkage, contour projector is unstable, the internal structure of product is unreasonable, causes quality of product to decline.
Summary of the invention
Instant invention overcomes the deficiencies in the prior art, propose a kind of heat seal type heat shrinkage sleeve, the product structure of this heat-contraction sleeve is reasonable, has very high shrinkage.
Technological scheme of the present invention is: a kind of heat seal type heat shrinkage sleeve, its ring-shaped section and ring-shaped structure, described loop configuration comprises binder layer and melten gel layer, and described binder layer is positioned at the outside of melten gel layer, is provided with a base-material melten gel tie layer between binder layer and melten gel layer.
Described loop configuration comprises base-material end skin and base-material end internal layer, between base-material end skin and base-material end internal layer, be provided with base-material tie layer.
Described loop configuration comprises melten gel end skin and melten gel end internal layer, between melten gel end skin and melten gel end internal layer, be provided with melten gel tie layer.
Be connected by described base-material melten gel tie layer between described base-material end internal layer and melten gel end skin.
The present invention has following beneficial effect:
The present invention efficiently solves the low problem of shrinkage in work progress, and described structure can make production process simplify, and manufacturing efficiency significantly improves, and improves the construction quality in construction.
Accompanying drawing explanation
The present invention is further illustrated below in conjunction with the drawings and specific embodiments.
Fig. 1 is cross section structure schematic diagram of the present invention.
Fig. 2 is perspective view of the present invention.
In figure, 1. binder layer; 2. heat-fusing glue layer; 3. base-material end is outer; 4. base-material end internal layer; 5. melten gel end is outer; 6. melten gel end internal layer; 7. base-material tie layer; 8. base-material melten gel tie layer; 9. melten gel tie layer.
Embodiment
Further illustrate below in conjunction with accompanying drawing, and unrestricted scope involved in the present invention.
Shown in Fig. 1 and Fig. 2, structure of the present invention is the columnar structures of hollow, its ring-shaped section and ring-shaped structure, this structure comprises binder layer 1 and heat-fusing glue layer 2, be provided with base-material melten gel tie layer 8 between which, make its structure more firm, there is higher shrinkage, described loop configuration also comprises one section of special firm layer, this firm layer contains at most seven thin layers, they are base-material end skins 3, base-material end internal layer 4, melten gel end skin 5, melten gel end internal layer 6, base-material tie layer 7, base-material melten gel tie layer 8 and melten gel tie layer 9, connected by base-material tie layer 7 between base-material end outer 3 and base-material end internal layer 4, connected by melten gel tie layer 9 between melten gel end outer 5 and melten gel end internal layer 6, connected by base-material melten gel tie layer 8 between base-material end internal layer 4 and melten gel end skin 5.When actual fabrication is produced, as required, above-mentioned firm layer also can only comprise in above-mentioned seven layers certain which floor, as certain four layers or certain five layers etc., example does not enumerate here.
Based on above-mentioned thought, can suitably change and revise within the scope of thought enlightenment of the present invention.
