Abstract
The utility model discloses an H-class insulating soft composite material which comprises a polyester film layer, ceramic inorganic synthetic fiber paper layers and adhesive layers, wherein the ceramic inorganic synthetic fiber paper layers are respectively adhered on the front and reverse sides of the polyester film layer by adhesives; and the adhesive layers are formed by the adhesives and are positioned between the polyester film layer and the ceramic inorganic synthetic fiber paper layers. According to the insulating soft composite material disclosed by the utility model, the performance of the insulating soft composite material is equivalent to that of a NHN (Nomex paper/Polyimide film/Nomex paper) material; the insulating requirement of an H-class motor is met; but the cost of the H-class insulating soft composite material is lower than that of the NHN material; and the H-class insulating soft composite material has simple preparation process.
Description
Technical field
The utility model relates to a kind of insulating material, particularly is applicable to the composite flexible material of H level electrical machine insulation.
Background technology
The insulation composite flexible material is big type of one in the insulating material, is mainly used in slot liner and the turn-to-turn of high-voltage motor and the lapped insulation of coil of motor.Along with development of electric power industry, middle and small motor is developing with higher ratio, so the composite flexible material that uses is also just more and more, particularly along with the development of special high temperature-resistant motor, the requirement of resistant to elevated temperatures composite flexible material also just increases greatly.
At present; Both at home and abroad NHN is generally all adopted in the slot liner of H level motor, insulation and liner insulation mutually, higher electrical equipment turn-to-turn insulation and the wrapping insulation of serviceability temperature, and this product plays an important role with the volume that reduces electrical equipment and electrical to improving running reliability of motor; The operation of specific type of electric machines such as steel rolling, crane, locomotive is that rotating moves repeatedly; Therefore altering a great deal of moment, do not have reliable insulating material then to be difficult to guarantee normal operation.And the production technology of producing required raw material polyimide film (PI) of NHN and aromatic polyamide paper
is monopolized by du pont company for many years always, thereby causes the market price of NHN very expensive.The composite material of production and selling mainly is the B-F level in the market; Like 6630 (DMD), 6631 (F level DMD), 6640 (NMN) etc.; Electrician's technical products is just towards high power, high microminiaturized development trend development on the now market; To develop the insulating composite material of each high thermal mechanical strength that long-term heat resistance reaches the high heat stability of 180 ℃ (H levels) or 200 ℃; And the above insulation of H level composite flexible material product is composited by polyimide film and homemade polysulfone fibre paper, and this product still is all can not compare with NHN (polyimide film aromatic polyamide paper composite flexible material) in reliability on outward appearance and performance.
Fierceness day by day along with the motor market competition not only requires the motor product capability and performance high, but also the price advantage ability survival and development should be arranged.For this reason, guaranteeing to reduce the manufacturing cost of motor product under motor product steady quality and the reliable premise, improve the motor product competitiveness and just seem particularly important.
Summary of the invention
The utility model technical problem to be solved is the deficiency that overcomes prior art, provides a kind of cost to reduce and satisfy the composite flexible material of H level electrical machine insulation requirement.
For solving the problems of the technologies described above, the utility model is taked following technical scheme:
A kind of H class F insulation composite flexible material, it comprises laminated polyester film, is bonded in the inorganic synthetic fibers ply of paper of positive and negative two pottery of laminated polyester film and the adhesive-layer between laminated polyester film and the inorganic synthetic fibers ply of paper of pottery that is formed by adhesive through adhesive respectively.
Preferably; The inorganic synthetic fibers ply of paper of said pottery is processed by the CeQuin or the TufQuin paper of the development and production of Quin-T company; They not only have good high-temperature stability, good comprehensive physical and mechanical properties and electrical insulation properties and excellent in water resistance, thermal conductivity, moisture absorption; And compare with E.I.Du Pont Company aromatic polyamide paper
, cheap.
Because the enforcement of above technical scheme, the utility model compared with prior art has following advantage:
According to the insulation composite flexible material of the utility model, its performance and NHN are suitable, satisfy the requirement of H level electrical machine insulation, but cost are lower than NHN, and preparation technology is simple.
Description of drawings
Below in conjunction with accompanying drawing and concrete embodiment the utility model is done further detailed explanation.
Fig. 1 is the structural representation of the utility model;
Wherein: 1, laminated polyester film; 2, the inorganic synthetic fibers ply of paper of pottery; 3, adhesive-layer.
Embodiment
As shown in Figure 1, according to the H of present embodiment insulation composite flexible material by laminated polyester film 1, be positioned at laminated polyester film 1 on positive and negative two the inorganic synthetic fibers ply of paper 2 of pottery and the adhesive-layer 3 that laminated polyester film 1 and the inorganic synthetic fibers ply of paper of pottery bond together constituted.
In this example, the material of the inorganic synthetic fibers ply of paper 2 of pottery is the CeQuin paper of Quin-T company development and production.
The preparation method of H class F insulation composite flexible material is following:
(1) preparation adhesive: get 25kg UK2600, with 50kg acetone solvent stirring and dissolving, and then the adding UK50003.57kg stir, promptly get adhesive.
(2), 80～100 ℃ of baking oven preheatings, film gluing, film cure, compound CeQuin paper, rolling, last, the environment of putting 50～60 ℃ in baking oven solidified 48 hours down, promptly got said insulation composite flexible material.
Test method according to " electric insulation composite flexible material " regulation is tested above-mentioned insulation composite flexible material, and the result is referring to table 1.
Table 1
Can be known by table 1: (1) present embodiment composite material is through conventional Performance Detection, the test of technique for applying property, compatibility test, complete machine type approval test and warm test, and each item performance index satisfy the requirement of H level electrical machine insulation.(2) mechanical strength of TFT composite material, deflection all are higher than national standard far away.Roll off the production line, in wiring and the winding overhang integer process, insulation notch, groove root, etc. the position defectives such as breakage or cracking do not appear; Its puncture voltage is higher than national standard about 50%.(3), this composite material uses as H level generator stator winding insulation through the UL authentication, and price is merely about 37% of NHN, on the outlet motor, uses, and economic benefit is very considerable.
More than the utility model has been done detailed description; Its purpose is to let the personage that is familiar with this art can understand the content of the utility model and implements; Can not limit the protection range of the utility model with this; All equivalences of doing according to the spirit of the utility model change or modify, and all should be encompassed in the protection range of the utility model.
