The intensity of mica paper, while improving the electrical strength of mica tape.In addition, this erasing simple process, it is easy to accomplish.
Compared with the prior art, the advantages of the present invention are as follows be provided with gluing oxidant layer by the two sides in mica paper, have
Help improve the electrical strength of mica tape.Meanwhile the mechanical performance of mica tape is improved by strengthening course, it ensure that mica paper not
It easily dampens, lose powder.The coil performance prepared when this mica tape is applied to motor is more stable.In addition, the cloud of this structure
Master tape construction is simple, and production cost is low.
Detailed description of the invention
The preferred embodiment of the present invention is described in detail below in conjunction with attached drawing, in figure:
Fig. 1 shows the sectional view of mica tape one embodiment according to the present invention；
The attached drawing is not drawn according to the actual ratio.
Specific embodiment
Below in conjunction with attached drawing, the present invention will be further described.
Fig. 1 shows the structure of mica tape 10.As shown in Figure 1, mica tape 10 includes mica paper 1, gluing oxidant layer 2, auxiliary
Adhesive layer 3 and strengthening course 4.Wherein, gluing oxidant layer 2 is respectively provided on the two sides of mica paper 1.It is arranged in each gluing oxidant layer 2
Adhesive layer 3 is assisted, and strengthening course 4 is set on each auxiliary adhesive layer 3.Reinforcement is provided in the two sides of mica paper 1 as a result,
Layer 4, so as to prevent the picking of mica tape 10, easy the problem of dampening, so that the coil performance of preparation is stablized.In addition, mica tape
10 include auxiliary adhesive layer 3, for enhancing the adhesive strength between mica paper 1 and strengthening course 4, to improve the machinery of mica tape 10
Performance.
Preferably, gluing oxidant layer 2 is epoxy glue layer.The toxicity of epoxide-resin glue is lower, no physiological side effects, to people
Body is harmless, while its own characteristic is good, is able to satisfy the use demand of mica tape 10.Preferably, auxiliary adhesive layer 3 is coupling agent
Layer.The adhesion strength that the two can be improved between coupling agent setting mica paper 1 and strengthening course 4, to improve the machinery of mica tape 10
Performance.Meanwhile resistance to ag(e)ing, proof stress and the electrical insulation capability of mica tape 10 can be improved by setting auxiliary adhesive layer 3.
In order to guarantee the mica content with higher of mica tape 10, quantification of 120-170 grams every square metre of mica paper 1.
By this arrangement ensure that the mica content with higher of mica tape 10, to reach motor insulation structure to mica content
Demand.
Below according to the manufacturing method of Fig. 1 detailed description mica tape 10:
Step 1 carries out mica paper 1 to unreel operation.During unreeling, so that tension suffered by mica paper 1 is no more than
3 newton, to guarantee that mica paper 1 will not be broken.In operation, it can be used and opened suffered by tension sensor induction mica paper 1
Power, and the tension sensed is transmitted on micro tension controlling device to adjust unwinding tension.It can make cloud in this way
Female paper 1 unreels smooth operation, and mica paper 1 will not be broken.
Gluing oxidant layer 2 is arranged in step 2 in the both side surface of mica paper 1.Gluing oxidant layer 2 is epoxy glue layer.And
