Abstract
The utility model discloses a kind of multilayer insulation paper; including high temperature resistance polyester film layer; nano protective film layer, nonwoven layer and brown paper is fixedly installed in the upper and lower ends of the high temperature resistance polyester film layer successively; and by the way that adhesive is set to be bonded between every layer, the adhesive is full of between every layer.The utility model bonds nano protective film layer respectively by adhesive in the upper side and lower side of high temperature resistance polyester film layer; improve insulation performance; and brown paper is bonded in upside nano protective film layer upper surface and downside nano protective film layer lower surface by adhesive; extend the aging speed of insulating paper; the thickness of adhesive is 2 2.5 times of high temperature resistance polyester film layer, increases the ability for preventing electric current breakdown insulating paper.
Description
Technical field
The utility model is related to insulating paper technical field, specifically a kind of multilayer insulation paper.
Background technology
Insulating paper is mainly used as the insulating materials of every electrical equipment such as cable, coil, and the insulating paper used at present is main
It is one layer of insulating paper, at work, insulation effect is poor, and by the use of electric current, aging speed is fast and electric current is worn and hit easily, influences
Using effect.
And the insulating paper sold on the market is all individual layer at present, and when during factory's manufacture motor to inlaying conducting wire in stator
Insulating paper is first put into, it is that multilayer is put into be put into insulating paper, very time-consuming, and formality is tediously long, and insulation effect is not
It is good, in this way, being affected to motor cost.
Utility model content
The purpose of this utility model is that it is in view of the drawbacks of the prior art and insufficient, a kind of multilayer insulation paper is provided.
To achieve the above object, the technical solution adopted in the utility model is：A kind of multilayer insulation paper, innovative point exist
In：Including high temperature resistance polyester film layer, nano protective film is fixedly installed in the upper and lower ends of the high temperature resistance polyester film layer successively
Layer, nonwoven layer and brown paper, and by the way that adhesive is set to be bonded between every layer, the adhesive be full of with every layer it
Between.
Further, the thickness of the high temperature resistance polyester film layer is 0.45-0.195mm.
Further, the thickness of the adhesive is 2-2.5 times of high temperature resistance polyester film layer.
Further, the thickness of the nano protective film layer is 0.015-0.09mm.
Further, the temperature classification of the nonwoven layer is B grades, thickness 0.05-0.1mm.
With the above structure, the utility model has the beneficial effect that：
1. the utility model bonds nanometer in the upper side and lower side of high temperature resistance polyester film layer by adhesive and protects respectively
Film layer improves insulation performance, and by adhesive under upside nano protective film layer upper surface and downside nano protective film layer
Surface bonds brown paper, extends the aging speed of insulating paper, the thickness of adhesive is the 2-2.5 of high temperature resistance polyester film layer
Times, increase the ability for preventing electric current breakdown insulating paper.
2. the utility model when inlaying insulating paper as motor stator, only need to disposably be inlayed, time saving and energy saving, work effect
Rate is high, while insulation effect is good, it is ensured that the quality of motor can reduce the production cost of motor, improve the market competitiveness.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Reference sign：
1 high temperature resistance polyester film layer, 2 nano protective film layers, 3 nonwoven layers, 4 brown paper, 5 adhesives.
Specific embodiment
The utility model will be further described below with reference to the accompanying drawings.
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and specifically
Embodiment, the present invention is further described in detail.It should be appreciated that the specific embodiments described herein are only used
To explain the utility model, it is not used to limit the utility model.
Referring to Fig. 1, a kind of multilayer insulation paper, including high temperature resistance polyester film layer 1, high temperature resistance polyester film layer 1 up and down
Both ends are fixedly installed nano protective film layer 2, nonwoven layer 3 and brown paper 4 successively, and between every layer by set adhesive 5 into
Row bonds, and adhesive 5 is full of between every layer.Feasible, the nonwoven layer 3 in other specific embodiments of the utility model
And brown paper 4 may be used the mode of half stacking and be configured, such as can nonwoven layer 3 be carried out doubling setting, that is, roll up
The non-woven fabrics of doubling bilayer is batched when taking, the required thickness of raw material can be reduced in this way, reduces cost, brown paper 4 can also be adopted
It is configured in a like fashion, if the brown paper for needing 4mm original in this way, doubling just only need the brown paper of 2mm later
It can realize, cost can be effectively reduced.
In the present embodiment, the thickness of high temperature resistance polyester film layer 1 is 0.45-0.195mm.High temperature resistance polyester film layer 1
Raw material are polyethylene terephthalate, have the function of that glued membrane is tough and tensile, adhesive strength is big, brushability is good, not wire drawing, and
Machine applies product and just cements solid, is not easy to disengage after tying up squeezing, and 1 surface of high temperature resistance polyester film layer is smooth, and when use reduces electricity
Friction between machine.
In the present embodiment, the thickness of adhesive 5 is 2-2.5 times of high temperature resistance polyester film layer 1, and increasing prevents electric current from hitting
Wear the ability of insulating paper.
In the present embodiment, the thickness of nano protective film layer 2 is 0.015-0.09mm.The raw material of nano protective film layer 2 are
Nano-aluminium oxide, fusing point are 2050 DEG C, and nano protective film layer 2 has higher insulation performance, high temperature resistance.
In the present embodiment, the temperature classification of nonwoven layer 3 is B grades, thickness 0.05-0.1mm, and heat resisting temperature is 130 degree,
With insulation, non-conductive, fire-retardant, anlistatig effect.
The above is merely intended for describing the technical solutions of the present application, but not for limiting the present application, those of ordinary skill in the art couple
The other modifications or equivalent replacement that the technical solution of the utility model is made, without departing from technical solutions of the utility model
Spirit and scope should all cover in the right of the utility model.
