Abstract
The utility model provides a polyimide film base strain gauge, which comprises a polyimide film base (1) and a metal foil (2). The utility model is characterized in that the polyimide film with specific specification is adopted as the base; a mucilage layer (4) is arranged between the polyimide film base (1) and the metal foil (2). The mucilage layer (4) enables the peeling strength of the strain gauge to be greatly improved, the thickness uniformity is ensured, and the anti-humid hot property, the creeping resistance, the zero restoring ability and the reliability of the strain gauge are also obviously improved, thereby the utility model is suitable for the occasions which require medium temperature and higher sensor accuracy.
Description
Technical field
The utility model relates to a kind of strain ga(u)ge, particularly a kind of Kapton substrate strain ga(u)ge.
Background technology
At present, known foil resistance strain gauge be by the electronic isolation material as substrate, xerox etching technique with photoetching and on the metal foil of compacting by rolling, form sensitive grid, form the weldering end in the sensitive grid rear end and make.The base material of strainometer has paper, epoxies, phenolic, polyesters, acetals, polyimide, glass fabric impregnation, sheet metal etc.Especially polyimide strainometer, what its substrate was adopted is the process that the liquid glue no-load solidify to form the strainometer substrate, the structure that forms product is one deck substrate and layer of metal paper tinsel, or one deck substrate and layer of metal paper tinsel and sealant, the strainometer substrate thickness consistance that this method is made relatively poor (deviation even can reach more than 30%).In test and using, these strainometers exist obviously that peel strength is low, the heat resistance poor performance, creep disperses and return problem such as zero instability, can't satisfy accurate LOAD CELLS, the weighing apparatus needs with sensor, force transducer, Industry Control, stress analysis.Tracing it to its cause, is owing to make the process defectiveness of product on the one hand, is because the existing structure of strainometer causes on the other hand.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, to propose a kind of Kapton substrate strainometer by improving the mode of strain ga(u)ge substrate fabrication.
The technical scheme that realizes above-mentioned purpose is: Kapton substrate strainometer, comprise Kapton substrate, metal forming, and it is characterized in that an adhesive-layer is arranged between Kapton substrate and metal forming.
Above-mentioned adhesive-layer is greatly improved the peel strength of strainometer, heat resistance performance, creep, return zero, stability also is significantly improved.
Description of drawings:
Fig. 1 is the structure section synoptic diagram of an embodiment of the utility model.
Fig. 2 is the vertical view of Fig. 1.
Among the figure: 1. Kapton substrate, 2. metal forming, 3. sealant, 4. adhesive-layer.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Embodiment illustrated in figures 1 and 2 is a kind of product with protective layer on essential structure of the present utility model basis.Essential structure as the utility model Kapton substrate strainometer is made up of Kapton substrate 1, metal forming 2 and adhesive-layer 4, and adhesive-layer 4 is with Kapton substrate 1 and metal forming 2 secure fit.In the present embodiment, an adhesive-layer 4 is also arranged between metal forming 2 and the sealant 3.
In the process of making above-mentioned strainometer, at first select the special Kapton of specific thicknesses for use, the thickness of this special Kapton has 25 μ m, 13 μ m, 7 μ m (deviation 1%), use suitable film surface disposal route that it is carried out surface treatment, as Kapton strainometer substrate 1, then with epoxy resin or phenolic aldehyde-epoxy resin as bonding agent, evenly be coated in metal forming 2 surfaces, and make alite paste form adhesive-layer 4 on the foil surface through precuring.At last metal forming 2 and Kapton substrate 1 are bonded together by adhesive-layer 4, carry out lamination and solidify to form, the thickness of adhesive-layer 4 is 2～5 μ m.Finally add thickness 2.5～5 μ m of strainometer sensitive grid, about 29.5～35 μ m of whole strainometer thickness or 17.5～23 μ m or 11.5～17 μ m.
The utility model Kapton substrate strainometer can be by customer requirements, increase sealant 3, the sealant material selection is identical with base material, an adhesive-layer 4 is also arranged between metal forming 2 and the sealant 3, and the strainometer general thickness after the sealing can reach 56.5～65 μ m, 32.5～41 μ m or 20.5～29 μ m.
The consistency of thickness of the said goods (deviation＜2%), heat resistance performance, creep, return zero, strainometer that stability etc. is better than existing in the market phenolic, polyimide, other every indexs also all satisfy GB/T13992-92 " strain ga(u)ge " GB A level product requirement, the occasion that is particularly useful for high-precision sensor and has relatively high expectations.
