Skill adjusts to form above-mentioned hole.The processing on enhancement layer can also be passed through by the later stage to punch to form above-mentioned hole, such as
The mode that later stage mechanical punching is carried out to molded film forms hole.
The insulating tape of above-mentioned three-decker can be prepared in the following manner：First, prepare thickness be in 0.01 to
Enhancement layer in the range of 2.0mm, on it the extensibility by adjusting enhancement layer material, adjust its grammes per square metre or on it plus
Hole that work punching forms perforation enhancement layer on enhancement layer, that minimum diameter is 0.01mm；Then, by dip-coating, roller coat, scrape
Insulating layer material is coated on the two sides of enhancement layer, the thickness of insulating layer of gained by the modes such as painting, brushing, squash type coating or spraying
In the range of 0.1mm to 3.0mm.The insulating tape of above-mentioned double-layer structure can be prepared by similar mode, absolutely
Edge layer thickness is in the range of 0.1mm to 3.0mm, and enhancing layer thickness is in the range of 0.01 to 2.0 millimeter, and the enhancing
The through hole that minimum diameter is 0.01mm is distributed on layer.
The sample 1 to 7 of insulating tape according to the present utility model is prepared in the manner described above and prepares comparison sample.
Then, the 180 degree peeling force of the insulating layer of these samples and comparison sample, root are tested according to standard GB/T/T 2792
The stretch breaking strength of the enhancement layer of these samples is tested according to standard GB/T/T528, is surveyed according to standard GB/T/T1408.1
It tries these samples and compares the adhesive tape breakdown voltage of sample and what they were wrapped in 10kV overhead lines respectively carve molded line
The wire clamps such as folder, parallel groove clamp, strain clamp or penetrating cable clamp (for three-layer insulated adhesive tape, attach one insulating layer aerial
The outer surface of line wire clamp, and for two layers of insulating tape, its insulating layer is made to attach the outer surface of overhead line wire clamp) on, Zhi Houtong
It crosses by hand or is removed them from the overhead line wire clamp using pocket knife, with the dismounting assessed these samples and compare sample
Difficulty.Acquired results are as shown in Table 1.
As can be seen from Table I, the breakdown voltage of sample 1 to 7 and comparison sample is all higher than 10kV, so can use
Make the insulating tape of the overhead line wire clamp of 10KV voltage class.And in sample 1 to 7, except sample 6 " can be torn open manually reluctantly
Except " in addition to, other samples 1-5 and 7 can be removed manually.And it removes by hand or removes the exhausted of sample 6 only by pocket knife
During edge adhesive tape, there is a situation where nonwoven layer layering, that is, when tearing upper-layer insulation film, non-woven fabrics is torn from centre.It is aobvious
So, the dismounting performance of sample 6 is not ideal enough.In contrast, the insulating tape of sample 1-5 and 7 is removed by hand or only by pocket knife
When, detachable comparison is clean.This may be due to the stretch breaking strength (30N/cm) of the enhancement layer of the insulating tape of sample 6 and its
Difference between the difference (20N/cm) that insulating layer subtracts obtained by 10N/cm in the 180 degree peeling force (30N/cm) on aluminium base surface
Caused by smaller (compared to the insulating tape of sample 1-5 and 7).
On the other hand, as can be seen from Table I, compared with the insulating tape of sample 1 to 7, the conventional insulator of sample is compared
Adhesive tape can not or be difficult to be removed manually from insulating clamp.And its remove effect be, by by hand remove or only by
Pocket knife removes the residue that the insulating tape is difficult to clean off the clean insulating tape, can leave a large amount of residue glues.This shows and tradition
Insulating tape compare, insulating tape according to the present utility model have good dismountable performance.
It should be appreciated that illustrative embodiments as described herein are illustrative and be not restrictive.It moreover, can be by each reality
Apply in mode other similar characteristics suitable for other embodiment of as described in each features or aspect description or in terms of.
Although being described in conjunction with the accompanying one or more embodiments of the utility model, those of ordinary skill in the art should
Work as understanding, in the case of without departing from the spirit and scope of the present invention defined by the following claims, can make each
The change of kind form and details.
