A kind of compound type insulating adhesive tape
Technical field
The utility model relates to compound type insulating tape technology field, relates to or rather a kind of compound type insulating adhesive tape.
Background technology
Compound type insulating adhesive tape generally adopts PVC material as base band at present, although PVC has good insulating property, poor aspect tension.
As can be seen here, above-mentioned existing compound type insulating adhesive tape still has many defects, and is urgently improved.
Summary of the invention
Technical problem underlying to be solved in the utility model is, overcomes the defect that existing compound type insulating adhesive tape exists, and a kind of compound type insulating adhesive tape is provided, and improves the tensile property of compound type insulating adhesive tape.
The utility model solves its technical problem underlying and realizes by the following technical solutions.According to a kind of compound type insulating adhesive tape the utility model proposes, comprise belt body extending longitudinally, belt body comprises the first layer PVC base band, the pressure-sensitive adhesive layer that second layer PVC base band and one deck are continuous, the first layer PVC base band is pasted second layer PVC base band, second layer PVC base band is pasted pressure-sensitive adhesive layer, between the first layer PVC base band and second layer PVC base band, comprise at least one nylon tape, the thickness of the first layer PVC base band is 1 millimeter to 2 millimeters, the thickness of second layer PVC base band is 1 millimeter to 2 millimeters, the thickness of pressure-sensitive adhesive layer is 0.5 millimeter to 2 millimeters, the long side direction of nylon tape is parallel to the plane at belt body place, nylon tape embeds the mid-way of PVC base band, nylon is with curling overlapping part, the distance of adjacent curling overlapping part is 0.5 centimetre to 5 centimetres, the length of curling overlapping part is 3 millimeters to 20 millimeters.
The utility model compared with prior art has obvious advantage and beneficial effect.From above technical scheme, the utility model is owing to adopting technique scheme, nylon tape is embedded to the centre of two-layer PVC base band, make nylon tape can play the effect of auxiliary tension, nylon is with curling overlapping part, can play the effect that discharges tensile deformation, can be so that adhesive tape stretching along shoestring direction.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model feature part, for making professional and technical personnel can better understand technique means of the present utility model, and can be implemented according to the content of specification sheets, below with preferred embodiment of the present utility model and coordinate accompanying drawing to be described in detail as follows.
Embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.
