Abstract
The invention discloses a sensor membrane. A canvas layer in the middle is covered by rubber layers at two sides, and bumps are arranged on the bottom of the sensor membrane and are of a three-layer structure, wherein the innermost layer combined with the bottom of the membrane is a bumped rubber layer, the middle layer is a bumped canvas layer, and the outermost side is a plastic layer. A preparation method of the sensor membrane comprises the following steps: firstly, coating rubber on 0.09mm nylon cloth by a coater, wherein each coating is 0.01mm thick; after coating for 35-40 layers, coating the other surface of the nylon cloth, which is turned over, for 35-40 layers, wherein each coating is 0.01mm thick; and performing punch forming on the cloth on a punch after coating, and pressing the bumps on the bottom of the membrane by a die, wherein the speed of the coater is 40r/m, and the temperature is 130-135 DEG C. As the bumps are arranged on the sensor membrane and the canvas layer and the rubber layer are added, the service life of the membrane is greatly prolonged.
Description
Technical field: the present invention relates to a kind of diaphragm of liquid sensor, the diaphragm on especially a kind of automobile engine oil sensor.
Background technology: sensor diaphragm, owing to often will promoting fluid, therefore is easy to wearing and tearing, and the life-span is very short.
Summary of the invention: for above-mentioned the deficiencies in the prior art, the invention provides longer sensor diaphragm of a kind of life-span and preparation method thereof.
For achieving the above object, the technical solution used in the present invention is: sensor diaphragm, the canvas layer in the middle of the rubber layer of both sides is wrapped in, be provided with salient point in the sensor diaphragm bottom.Salient point is three-decker, and bottom diaphragm, the innermost layer of combination is the salient point rubber layer, and centre is the salient point canvas layer, and outermost is plastic layer.
The preparation method of sensor diaphragm, at first use coating machine coating rubber on the nylon cloth of 0.09mm, applies 0.01mm at every turn, and after being painted with the 35-40 road, the another side of the coating nylon cloth that turns over applies 0.01mm at every turn, also applies the 35-40 road.Punch forming on punch press after coating, finally press salient point in the bottom that utilizes mould at diaphragm.The speed of coating machine is 40 rev/mins, and temperature is 130-135 ℃.
The present invention is provided with salient point in sensor diaphragm, and has increased canvas layer and rubber layer, and greatly improve the service life of diaphragm.
The accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention 1.
Fig. 2 is the cutaway view of embodiment 1.
Fig. 3 is the cutaway view of salient point.
Fig. 4 is the structural representation of embodiment 2.
Fig. 5 is the structural representation of embodiment 3.
The specific embodiment:
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out to clear, intactly description, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Give the embodiment in the present invention, those of ordinary skills, not making under the creative work prerequisite the every other embodiment obtained, belong to the scope of protection of the invention.
As shown in Figure 1-Figure 3: sensor diaphragm, the canvas layer 3 in the middle of the rubber layer 1,4 of both sides is wrapped in, be provided with four salient points 1 in the sensor diaphragm bottom.Salient point 1 is three-decker, and bottom diaphragm, the innermost layer of combination is salient point rubber layer 6, and centre is salient point canvas layer 7, and outermost is plastic layer 5.
As shown in Figure 4: its structure is similar to embodiment 1, and just salient point is 6.
As shown in Figure 5: its structure is similar to embodiment 1, and just salient point is 7.
The preparation method of sensor diaphragm, at first use coating machine coating rubber on the nylon cloth of 0.09mm, applies 0.01mm at every turn, and after being painted with 40 roads, the another side of the coating nylon cloth that turns over applies 0.01mm at every turn, also applies 40 roads.Punch forming on punch press after coating, finally press salient point in the bottom that utilizes mould at diaphragm.The speed of coating machine is 40 rev/mins, and temperature is 135 ℃.
