Abstract
The utility model aims to design a thermal shrinkage and thermal fused polymer composite tape, which is characterized in that the structure thereof is the composite layer and the marginal structure of the tape composed of a crosslinking polyolefin tape having longitudinal shrinkage performance and a linear thermoplastic polymer which can be fused and flow after heated or thermal fused adhesive so that the applied reliability can be increased. A thermal fused layer surface can be overlapped with form 1/2 to 1/3 towards the protected position and can be spirally wound outside the protected position so that adhesive edge is positioned under an annular tape. In this way, the edge adhesive and the inner layer can start fusing and flowing under the shrinkage temperature of the outer layer. Space between two overlapped tapes can be filled. Simultaneously two layers can be fused into integration and tightly shrunk at the protected position.
Description
The utility model belongs to the structural design of thermal contraction and heat fusing polymer two-layer compound insulating tape.
Existing patent 95204567.2 discloses the structure and the structure picture of the compound shrink belt of enwinding type.Its product is the compound inslation band that the internal layer by the heating skin of vertical shrinkage polyolefine and heat fusing polyolefin or PUR constitutes.The occasions such as reparation that have been widely used in the sealing of the minor insulation of aerial bare line, the busbar that confluxes and protection, damaged cable sheath.This product structure and structure picture and flat rubber belting and spiral typing band ratio have made things convenient for application, and improved application quality, but still unavoidably in use, the overlapping layer inward flange stay defectives such as bubble, influences its electrical property and protection effect.
The purpose of this utility model is a kind of thermal contraction of design and heat fusing polymer composite band, the architectural feature of this band is the time to have vertical shrinkage cross-linked polyolefin band and heating melt-flowable linear thermoplastic polymer by heating, or the composite bed and the marginal texture of the band of PUR composition, to increase reliability of applying.
The present invention is with the difference of patent 95024567.2, on one side of thermal contraction and heat fusing two-layer structure composite band, increase the glue limit structure that an internal layer same material constitutes, glue limit and inner layer material be melt-flowable under outer heat shrink temperature all, work gap, the effect between tack coat of filling.During application, Jiao Bianze is enough to fill the space between the spiral winding overlapping layer, increases the sealing reliability of heat shrinkage belt.
Embodiment of the present utility model, be described below in conjunction with the accompanying drawings, figure one is the cross section schematic diagram of thermal contraction and heat fusing polymer two-layer compound band, its skin (1) is to have heating vertically to shrink the cross-linked polyolefin formation, internal layer (2) is by linear thermoplastic polyolefin, or ethylene-vinyl acetate PUR or polyamide hot formation, outer (1) and internal layer (2) compound tense, internal layer (2) is wanted the wide skin (1) that goes out, and forms a glue limit.
The utility model is the same with the shrink belt that Chinese patent 95.204567.2 announces, is used for garden type conductor, busbar and profiled-cross-section conductor insulation, waterproof, anti-salt fog and protection.During application with hot meltable layer towards protected position, 1/2～1/3 overlapping spiral is under next endless belt the glue limit outside it.Like this, under the outer shrinkage temperature of heating, glue limit, edge and internal layer begin melt-flow.Fill the space of two overlapping interbands.Two layers of fusion simultaneously are one, tighten in protected position.
