Abstract
The invention provides a self-lubricating heat-shrinkable sleeve. The self-lubricating heat-shrinkable sleeve is characterized by comprising an inner layer body and an outer layer body, wherein the outer layer body is made of a heat-shrinkable material; and the inner layer of the heat-shrinkable sleeve is provided with a continuous lubricating material layer. Because the inner layer of the self-lubricating heat-shrinkable sleeve is provided with the continuous lubricating material and the lubricating material can form a continuous lubricating layer between the heat-shrinkable material and a protected object, the aim of a convenient sleeve is fulfilled effectively. In addition, the outer layer material of the self-lubricating heat-shrinkable sleeve can be subjected to radiation cross linking by utilizing high-energy electron beams or high-energy gamma rays and then expanded to form the heat-shrinkable sleeve by heating, so that an effect of heat shrinkage is achieved.
Description
Technical field
The present invention relates to a kind of structure of heat-shrinkable tube, specifically be meant a kind of self-lubricating type heat-shrinkable T bush that is applied to electric power system or electronic applications.
Background technology
In the application process of heat-shrinkable T bush, heat-shrinkable T bush must be enclosed within and just can carry out pyrocondensation on the protected object to guarantee pyrocondensation protection to protected object.And in the existing heat-shrinkable T bush technology, owing to be single layer structure or band glue double-decker mostly, comparatively when complicated (a plurality of bent angle) or long protected object, cause the sleeve pipe difficulty easily in some shapes of cover.
Summary of the invention
The present invention solves the technical solution problem of wanting in order to reach, and a kind of self-lubricating type heat-shrinkable T bush is provided, because this cover inner tube layer is provided with continuous lubriation material, thereby reaches the purpose that makes things convenient for sleeve pipe.
In order to achieve the above object, the technical solution adopted in the present invention is: a kind of self-lubricating type heat-shrinkable T bush is provided, and described heat-shrinkable T bush comprises the outer layer body that internal layer body and heat-shrinkage material are made, and the internal layer of described heat-shrinkable T bush is provided with continuous lubriation material layer.
The above-mentioned major technique feature of foundation: described internal layer body is to be made of lubriation material, and described this lubriation material is: a kind of or two or more blends of organosilicon material, talcum powder or other lubriation materials.
The above-mentioned major technique feature of foundation: described outer layer body is to be made by crosslinking with radiation type crystalline polyolefin material, described crosslinking with radiation type crystalline polyolefin material is: wherein a kind of in high density polyethylene pipe (HDPE), polyethylene from high pressure process (LDPE), linear polyethylene (LLDPE), polyethylene or the polyethylene-ethyl acrylate (EEA), perhaps wherein any two or more blend.
The above-mentioned major technique feature of foundation: the inside that the internal layer body is evenly distributed on described outer layer body by co-extrusion, application pattern.
Beneficial technical effects of the present invention: because of the internal layer at the lubricating type heat-shrinkable T bush is provided with continuous lubriation material, this lubriation material can form continuous lubricating layer between material contracting with heat is with protected object, thereby effectively reaches the purpose that makes things convenient for sleeve pipe.In addition, the cladding material of above-mentioned self-lubricating type heat-shrinkable T bush can utilize high-power electron beam or high energy gamma rays, carries out crosslinking with radiation, and heating expands into heat-shrinkable T bush then, the feasible effect that reaches pyrocondensation.
Description of drawings
Fig. 1 is the self-lubricating type heat-shrinkable T bush structural representation in the first embodiment of the invention;
Structural representation when Fig. 2 is a self-lubricating type heat-shrinkable T bush suit in the second embodiment of the invention.
Embodiment
Technical scheme is for a better understanding of the present invention described embodiment provided by the invention in detail below in conjunction with accompanying drawing.
Please refer to shown in Figure 1ly, below in conjunction with first embodiment self-lubricating type heat-shrinkable T bush provided by the present invention is described, the outer layer body 2 that this self-lubricating type heat-shrinkable T bush comprises internal layer body 1 and places internal layer body 1 outside.Internal layer body 1 is made of lubriation material.This lubriation material can be the blend that organosilicon material or talcum powder or other lubriation materials or above-mentioned any two kinds (or more than) chemical substance is mixed.By co-extrusion, coating or other modes material internal with even distribution of inner layer material and outer layer body.Outer layer body 2 is made of crosslinking with radiation type crystalline polyolefin material, and this crosslinking with radiation type crystalline polyolefin can be the blend that the blend that mixes of high density polyethylene pipe (HDPE) or polyethylene from high pressure process (LDPE) or linear polyethylene (LLDPE) or polyethylene or dimly-ethyl acrylate (EEA) or above-mentioned any two kinds of chemical substances or above-mentioned chemical substance are mixed.By fusion co-extrusion technology or coating or inner layer material is evenly distributed other modes and the self-lubricating type heat-shrinkable tube is made in cladding material inside.
Please refer to shown in Figure 2ly, this example is the effect that self-lubricating type heat-shrinkable T bush application suite is reached: described cable is followed successively by protected object 3 (being suitable for various complicated shapes) from inside to outside, the protected object 3 outer self-lubricating type heat-shrinkable T bushs that use.
Because the lubriation material of internal layer body 1 can form effective lubricating layer between the pyrocondensation insulating material of outer layer body 2 and protected object 3, can reduce the pyrocondensation insulated tube in the cover process of assembling with the frictional force of protected object 3, thereby reach convenient purpose of installing.
Disclose a kind of self-lubricating type heat-shrinkable T bush, this self-lubricating type heat-shrinkable T bush is applied to electric power system or electronic applications, and this self-lubricating type heat-shrinkable T bush comprises internal layer body and the outer layer body that places the internal layer external body.Because of the internal layer of this self-lubricating type heat-shrinkable T bush is provided with the continuous lubrication material, because of this lubriation material is forming lubricant body behind the heat-shrinkable T bush suit between outer field material contracting with heat is with protected body, reduced the installation resistance, the convenient installation from you.The self-lubricating type heat-shrinkable T bush comprises internal layer body and the outer layer body that places the internal layer external body, thereby effectively reaches the purpose that makes things convenient for suit.In addition, above-mentioned self-lubricating type heat-shrinkable T bush can utilize high-power electron beam or high energy gamma rays, carries out crosslinking with radiation, and heating expands into the double layer continuous complex then, makes to reach compound and the pyrocondensation effect.
More than a kind of self-lubricating type heat-shrinkable T bush that the embodiment of the invention provided is described in detail, for one of ordinary skill in the art, thought according to the embodiment of the invention, part in specific embodiments and applications all can change, in sum, this description should not be construed as limitation of the present invention.
