Description

Fabric reinforced watchband

Technical Field

The application relates to the field of rubber production, in particular to a fabric reinforced watchband.

Background

The watch type sphygmomanometer is a perfect solution worn intelligently in the field of health monitoring, whether the watch type sphygmomanometer can reach the medical grade boundary is the blood pressure monitoring precision and is related to various factors, the important point is the elastic modulus of the watchband, and if the elastic modulus of the watchband is too small, a large measurement error is caused by the fact that the watchband is stressed and expanded; the watchband of the watch is divided into silicon rubber, fluororubber, fabric and metal watchbands according to materials; for a watch type sphygmomanometer, the common silicon rubber and fluororubber watchbands are molded in a mold after vulcanization treatment to form the watchbands, the material molecular chains of the watchbands are long, the watchbands have good flexibility, and when an air pump inflates an air bag, the internal pressure of the air bag causes the watchbands to expand in a large range, so that the pressure efficiency of the air bag on an ulnar artery and a radial artery is reduced, and the measured blood pressure value is higher; the elastic modulus of the fabric watchband is small, the fabric watchband is easy to stretch and retract, the measured value of blood pressure is easy to be high, meanwhile, the problems of fabric color change, odor and the like caused by sweat and the like can be solved, the metal watchband has very high elastic modulus, and is relatively suitable for measuring the blood pressure value from the aspect of mechanical property, but the metal watchband is difficult to adjust the wearing tightness in real time and is not suitable for the convenience of blood pressure measurement.

In the related technology, the chopped fibers and the filler capable of increasing the elastic modulus are blended and molded with the silicon rubber or the fluororubber, so that the elastic modulus of the watchband can be increased to a certain extent, and the process is easy to realize. However, if the proportion of the chopped fibers or fillers added is too large, the flexibility of the band is greatly reduced, which results in poor hand feeling and wearing comfort of the band. If the proportion of the chopped fibers or the fillers is too small, the increase of the elastic modulus is not obvious, and the requirement of blood pressure measurement cannot be met. Moreover, the chopped fibers appear as threads on the surface layer of the watch band, and are likely to cause skin allergy. The long-cut glass fiber can enhance the mechanical property of the rubber material, but is not easy to fix in the rubber material, so that the mechanical property of the rubber material is unstable, and the measuring precision of the watch type sphygmomanometer is affected by the watchband manufactured by the conventional technical scheme of directly filling the long-cut glass fiber in the rubber. In view of this situation, there is a proposal in wayside et al to improve the elastic modulus of the band by using PI (polyimide) as a reinforcing material. However, the reinforced polyimide rubber watchband reinforced by the sheet polyimide has the problems that interface separation is easy after the rubber watchband is folded, and the rubber watchband reinforced by the sheet polyimide has hard hand feeling and is uncomfortable to wear.

At present, a fabric reinforced watchband which has high elastic modulus and is comfortable to wear does not exist.

The present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

As shown in fig. 1, a fabric-reinforced band of the present embodiment is used to attach a wristwatch type blood pressure monitor so that the user wears the wristwatch type blood pressure monitor on the arm. One end of the fabric reinforced watchband is fixed on the watch type sphygmomanometer. The fabric reinforced watch band comprises a vulcanized rubber layer 3 and a vulcanized rubber layer 2 filled in the vulcanized rubber layer. The vulcanized long-cut glass fiber 1 is filled in the vulcanized colloid layer.

Specifically, the vulcanized colloidal layer is a colloidal material layer formed by mixing and stirring raw materials forming the vulcanized colloidal layer, shearing and emulsifying at a high speed to form a homogeneous colloidal slurry, vulcanizing and drying the colloidal slurry at 120 to 130 ℃, then cutting the dried material into strips, and further vulcanizing at 200 to 250 ℃. The vulcanized long-cut glass fiber is obtained by impregnating an existing long-cut glass fiber material with a coupling agent, performing coupling treatment, and vulcanizing the long-cut glass fiber at a high temperature. And the long-cut glass fiber after the coupling treatment is firstly immersed into the emulsified homogeneous mucilage, so that the long-cut glass fiber is completely wrapped by the homogeneous mucilage and then is vulcanized together with the homogeneous mucilage, and the vulcanization temperature of the long-cut glass fiber and the mucilage is consistent with the vulcanization process. The treated vulcanized long-cut glass fiber is completely wrapped in vulcanized colloid, and the vulcanized long-cut glass fiber and the vulcanized colloid form a fabric silica gel slice layer together. So, outside wrapping up the fabric silica gel section layer with rubber materials to carry out high temperature vulcanization with rubber materials in the mould of production watchband and form vulcanized rubber layer after, vulcanized rubber layer is fixed in the intraformational position of vulcanized rubber layer, and then makes the intraformational position of long-cut glass fiber at vulcanized rubber fixed. This is done. The long-cut glass fiber can stably exist in the vulcanized rubber layer, and the mechanical property of the manufactured watchband is strengthened, so that the watchband has higher elastic modulus compared with the existing watchband, is less prone to being elongated under external tension, and has strong recovery capability after deformation. The watch type sphygmomanometer connected with the watchband is guaranteed to be capable of being worn stably and not to be loosened, more comfortable wearing experience is obtained, and measuring accuracy of the watch type sphygmomanometer is guaranteed. And the material cost and the processing cost for manufacturing the watchband are low, and the watchband is suitable for mass production.

Furthermore, the vulcanized long-cut glass fiber is made of an electronic grade alkali-free glass fiber cloth material. The electronic grade alkali-free glass fiber cloth has high purity and high tensile strength, so that the electronic grade alkali-free glass fiber cloth has good wettability and strong permeability in a coupling agent, has better flexibility compared with materials such as chopped fibers and the like, is convenient to process, and correspondingly improves the elastic modulus of a finished watchband, and in a further scheme, 1080 or 106 glass fiber cloth is specifically selected as the glass fiber cloth.

Furthermore, vulcanize long cut glass fiber and extend along the length direction of fabric reinforcing watchband in the vulcanize colloid layer, vulcanize the extending direction of long cut glass fiber promptly and be unanimous with the extending direction of watchband for the watchband is fully promoted at length direction's mechanical properties, guarantees that the watchband can keep its shape under the pulling force.

Furthermore, one end of the fabric reinforced watchband close to the watch type sphygmomanometer is provided with an arc-shaped section 4. The vulcanized long-cut glass fiber is bent and extends along the extending direction of the arc section at the arc section. The vulcanized long-cut glass fiber can also play a role in reinforcing the mechanical property of vulcanized rubber at the bent part of the watchband, further ensures that the watchband is not easy to be pulled to deform, can automatically recover after deformation, simultaneously ensures that the end part of the watchband is not easy to break, and ensures the connection stability of the watchband and the watch-type sphygmomanometer.

Furthermore, one end of the fabric reinforced watchband, which is far away from the watch type sphygmomanometer, is provided with a shaft hole 5. The shaft hole is used for arranging a conventional clamping structure for fixing the watchband on the arm of a user, and the clamping structure is also used for adjusting the tightness of the watchband. Vulcanize long glass fiber of cutting and encircle the shaft hole setting in the shaft hole outside, long glass fiber of cutting has the reinforcing effect to shaft hole position department promptly, and because long glass fiber's of cutting integrality, short glass fiber relatively, because vulcanize long glass fiber of cutting parcel in the vulcanize colloid, its difficult filiform appearance that forms and expose on the watchband top layer after the bending, therefore can fully strengthen the watchband in shaft hole department, reduce the watchband and warp or even cracked possibility because of the pulling force in shaft hole department.

Further, as raw materials of the vulcanized rubber, there are: vinyl silicone oil, hydrogen-based silicone oil, a platinum catalyst, a filler and an auxiliary agent. The raw materials are as follows according to the mass portion: 100 parts of vinyl silicone oil, 55 parts of hydrogen-based silicone oil, 1-2 parts of platinum catalyst, 80-95 parts of filler and 0.5-1 part of assistant; the most preferable embodiment is that 100 parts of vinyl silicone oil, 55 parts of hydrogen-based silicone oil, 1 part of platinum catalyst, 90 parts of filler and 0.8 part of auxiliary agent.

Further, as the raw materials of the vulcanized rubber, there are: fluorosilicone rubber, a vulcanizing agent, a reinforcing agent, a coloring agent, a structure control agent, a heat-resistant agent and a solvent. The raw materials are as follows according to the mass portion: 100 parts of fluorosilicone rubber, 1-2 parts of vulcanizing agent, 50 parts of reinforcing agent, 20 parts of coloring agent, 1 part of structure control agent and 3-10 parts of heat-resistant agent; in a preferable scheme, the structure control agent is diphenyl silanediol, the reinforcing agent is fumed silica or insulating whiskers or chopped glass fibers, the dosage of the vulcanizing agent is 2 parts, and the heat-resistant agent is ferric oxide or/and silicon micropowder. When the heat-resistant agent is only ferric oxide, the mass part of the heat-resistant agent is 3 parts; when the heat-resistant agent is only the silicon micropowder, the mass part of the heat-resistant agent is 10 parts; the colorant is selected based on the particular color of the finished watch band, e.g., carbon black when the finished watch band is black.

Example two

In the related art, the watch band often has a plurality of linearly distributed holes 6, and each hole is arranged along the length direction of the watch band for adjusting the tightness when the watch band is worn. In actual production, it is found that the fabric-reinforced watch band described in the above-mentioned embodiment is likely to have burrs formed by the long-cut glass fibers 1 at the positions of the band having the openings 6, because it is difficult to completely wrap the long-cut glass fibers with the rubber cured outside the long-cut glass fibers during processing, and a part of the long-cut glass fibers is exposed and extends into the openings of the watch band to form burrs. Such burrs affect the appearance and hinder the tightness adjustment when the watch band is worn. To solve this problem, the present embodiment is proposed. As shown in fig. 2, the difference between this embodiment and the first embodiment is that, in this embodiment, before wrapping the vulcanized rubber layer with the vulcanized rubber layer, the vulcanized rubber layer is cut off at a position corresponding to the opening 6 on the watch band, and PI (polyimide) material is filled in a position corresponding to the opening of the watch band on the cut plant silicone sheet to form a PI isolation layer 7, and after the watch band is formed, the PI material is used to block the long-cut glass fibers, so that the long-cut glass fibers are not exposed in the opening, thereby solving the problem of burrs at the opening of the watch band. Meanwhile, the PI material can also play a certain reinforcing effect on the mechanical property of the watchband, and the overall performance of the watchband is ensured.

The foregoing description is only exemplary of the preferred embodiments of the disclosure and is illustrative of the principles of the technology employed. It will be appreciated by those skilled in the art that the scope of the invention in the embodiments of the present disclosure is not limited to the specific combination of the above-mentioned features, but also encompasses other embodiments in which any combination of the above-mentioned features or their equivalents is made without departing from the inventive concept as defined above.
