SUMMERY OF THE UTILITY MODEL

The utility model provides a compound insulating strip structure aims at solving one of the technical problem that exists among the prior art at least. The utility model discloses a compound insulating strip structure combines the advantage of two kinds of types strips among the background art, and not only convenient to use still has certain thickness, can laminate completely by the winding surface.

The technical scheme of the utility model an aspect is a compound insulating strip structure, and it includes: a first plastic insulating layer having adhesiveness; a second plastic insulating layer having adhesiveness; a polymer elastomer layer sandwiched between the first plastic insulating layer and the second plastic insulating layer; a release paper layer covering the first plastic insulation layer or the second plastic insulation layer.

Further, one or more of the first plastic insulating layer and the first plastic insulating layer are tacky polyurethane putty layers.

Further, the polymer elastomer layer includes a layered polyurethane material.

Further, the polymer elastomer layer includes a layered silicone material.

Furthermore, the release paper layer is provided with a plurality of cutting lines which are vertical to the length direction of the strip structure and have consistent intervals.

Another aspect of the technical solution of the present invention is a composite insulation strip structure, comprising a first plastic insulation layer having viscosity; a second plastic insulating layer having adhesiveness; a polymer elastomer layer sandwiched between the first plastic insulating layer and the second plastic insulating layer; and the two release paper layers are covered on the first plastic insulating layer and/or the second plastic insulating layer. One or more of the first plastic insulating layer and the first plastic insulating layer are tacky polyurethane putty-like layers. The polymer elastomer layer comprises a layered polyurethane material. The polymer elastomer layer comprises a layered organic silicon material. The release paper layer is provided with a plurality of cutting lines which are vertical to the length direction of the strip structure and have consistent intervals.

The utility model has the advantages as follows:

1. through the daub state form, solved and easily formed the air chamber or by pricking when being twined thing surface irregularity to and hardly satisfy the problem of specific shape laminating parcel.

2. Through sandwich structure, effectively solved the weaker problem of traditional insulating tape intensity to high voltage insulating ability has effectively been promoted.

3. The strip structure supports winding, realizes convenient carrying of materials and is simple to construct.

4. The composite insulation polyurethane cement strip has strong bonding force, can realize complete insulation of one product, and is not easy to age and lose efficacy.

Detailed Description

The conception, specific structure and technical effects of the present invention will be described clearly and completely with reference to the accompanying drawings and embodiments, so as to fully understand the objects, aspects and effects of the present invention. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.

Furthermore, the description of the upper, lower, left, right, top, bottom, etc. used in the present invention is only relative to the mutual position relationship of the components of the present invention in the drawings. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any combination of one or more of the associated listed items.

It will be understood that, although the terms first, second, third, etc. may be used herein to describe various elements, these elements should not be limited by these terms.
