[0031] Figure 1 It is a schematic flow chart of the preparation process of the silicone product for fabric bonding provided by the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] In order to make the purpose, technical solutions and effects of the present invention clearer and more definite, the following further describes the present invention in detail with reference to the accompanying drawings and by way of examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0033] It should be noted that when a component is referred to as being "mounted on", "fixed to" or "disposed on" another component, it can be directly on the other component or there may be an intermediate component at the same time. When a component is referred to as being "connected to" another component, it can be directly connected to the other component or there may be an intermediate component at the same time.

[0034] It should also be noted that the terms of orientation such as left, right, up, and down in the embodiments of the present invention are only relative concepts to each other or are referenced based on the normal use state of the product, and should not be considered restrictive.

[0035] In the fields of wearable devices, medical and sports fields, industrial and protective equipment fields, home and consumer electronics fields, etc., there is a certain demand for silicone products for fabric bonding; however, at present, the preparation of silicone products bonded to fabrics in the industry is relatively complex and the qualified product rate is low. At the same time, the preparation process takes a long time and the cost is high, and the bonding effect between the prepared silicone product and the fabric is not good.

[0036] In view of the deficiencies of the prior art, the present application provides a preparation process for a silicone product for fabric bonding. Please refer to Figure 1 , including:

[0037] S100. Place the fabric and silicone in a mold, and perform vulcanization molding on the fabric and silicone to form a silicone fabric composite;

[0038] S200. Cut the silicone fabric composite into the required size and shape;

[0039] S300. Coat an adhesive layer on the silicone fabric composite;

[0040] S400. The silicone fabric composite is laminated with the adhesive layer by hot pressing or high-frequency process to form a silicone product. The silicone product prepared by the preparation process of the present application improves the problem of poor adhesion effect between the silicone product and the fabric in the prior art. The preparation process is simple and the cost is low. It should be noted that the fabric vulcanized and formed together with the silicone in the present application is the raw material of the silicone product, and the fabric adhered to the silicone product is the finished fabric.

[0041] Before placing the fabric and the silicone in the mold, it also includes cleaning the mold and coating a release agent on the mold; the mold is thoroughly cleaned by an ultrasonic cleaning device to remove the oil stains and impurities on the mold surface; the oil stains and impurities on the mold surface will affect the vulcanization effect of the silicone, resulting in problems such as defects and bubbles on the surface of the silicone product. After cleaning, dry the mold with a clean non-woven fabric, and then evenly coat a layer of release agent; coating the release agent is to facilitate the smooth removal of the product from the mold after vulcanization and forming, and to avoid the adhesion between the vulcanized silicone and the mold when taken out from the mold, which affects the product quality.

[0042] Specifically, when the silicone is liquid silicone, the step of placing the fabric and the silicone in the mold and performing vulcanization and forming treatment on the fabric and the silicone to form a silicone fabric composite includes:

[0043] Preheat the mold, and the preheating temperature is 100°C - 300°C;

[0044] Put the fabric into the preheated mold and close the mold after arranging it flat;

[0045] Inject the liquid silicone into the mold, and perform vulcanization and forming treatment on the liquid silicone and the fabric.

[0046] In the embodiment of the present application, preheating the mold creates an ideal initial environment for the injection and vulcanization of the liquid silicone. In this temperature range, the mold can quickly transfer heat to the injected liquid silicone, making it quickly reach the temperature required for vulcanization. Compared with the situation of not preheating or improper temperature, preheating can make the liquid silicone evenly heated in a shorter time, accelerate the vulcanization reaction, and reduce the problem of uneven vulcanization caused by the temperature gradient, thereby improving the bonding effect between the liquid silicone and the fabric, and thus improving the physical properties and forming quality of the silicone product. Putting the fabric into the preheated mold and closing the mold after tensioning and flattening ensures the stability and uniformity of the fabric during the vulcanization process; the flat fabric can provide a uniform contact surface for the liquid silicone, enabling the liquid silicone to fully and evenly contact the fabric during the flow filling process; if the fabric has wrinkles or is uneven, local accumulation or insufficient filling may occur in the liquid silicone after injection and vulcanization, resulting in poor bonding effect between the vulcanized liquid silicone and the fabric and affecting the strength of the silicone product.

[0047] Further, the step of injecting liquid silicone into the mold and vulcanizing and molding the liquid silicone and the fabric also includes: the vulcanization and molding conditions are a temperature of 120°C–200°C and a vulcanization time of 20s–120s. Preferably, the vulcanization and molding conditions for the liquid silicone and the fabric are a temperature of 150°C. If the temperature is lower than 120°C, the activity of the silicone molecules is insufficient, resulting in low strength and poor elasticity of the silicone. If the temperature is higher than 200°C, it may cause over-vulcanization of the liquid silicone, making it brittle and losing flexibility, affecting the service life of the silicone product; the vulcanization time can be adjusted adaptively according to the thickness of the silicone layer of the silicone product. A shorter vulcanization time is applicable to thinner silicone layers or scenarios with high production efficiency requirements. At this time, at a suitable temperature, the silicone can be quickly molded. A longer vulcanization time is applicable to thicker silicone layers or silicone products with more stringent silicone performance requirements, enabling the silicone and the fabric to be fully bonded.

[0048] Further, S100, placing the fabric and the silicone in the mold and performing vulcanization and molding treatment on the fabric and the silicone to form a silicone fabric composite also includes applying low-frequency vibration to the mold, with a frequency of 10hz–50hz, an amplitude of 0.1–0.5mm, and a duration of 30s–90s; since the liquid silicone has fluidity, the vibration can help it better fill the gaps in the mold, improve the density and uniformity of the product. At the same time, the vibration can promote the penetration of the liquid silicone between the fabric fibers, remove the air bubbles between the silicone and the fabric, and improve the bonding quality of the product.

[0049] Specifically, when the silicone is solid silicone, the step of placing the fabric and the silicone in the mold and performing vulcanization and molding treatment on the fabric and the silicone to form a silicone fabric composite includes:

[0050] Stacking the solid silicone and the fabric in the mold and closing the mold;

[0051] Preheating the mold, with a preheating temperature of 100°C–300°C;

[0052] Performing vulcanization and molding treatment on the solid silicone and the fabric.

[0053] In the embodiment of the present application, the counter silicone and the cloth are stacked in the mold and the mold is closed, which ensures that the solid silicone and the cloth are in close contact during the vulcanization process. The stacking maximizes the fitting area of ​​the two and provides a good foundation for the subsequent combination. The mold closure creates a relatively closed and stable environment, which helps to evenly apply pressure and heat during the vulcanization process, so that the solid silicone and the cloth can be better combined. Because solid silicone needs to be at a certain temperature to start the vulcanization reaction, the mold is preheated to 100℃-300℃, which creates suitable initial conditions for the vulcanization of solid silicone. In this range, solid silicone can quickly reach the temperature required for vulcanization, so that the solid silicone is heated evenly in a shorter time, and the vulcanization reaction is accelerated. If vulcanization is carried out directly without preheating, the solid silicone will heat up slowly, and the vulcanization time will be greatly extended, which will not only reduce the preparation efficiency of silicone products, but also may affect the physical properties of silicone products due to insufficient vulcanization. In addition, preheating the solid silicone together with the fabric can allow the fabric to gradually adapt to temperature changes and avoid damage due to sudden temperature changes during subsequent vulcanization. Preheating changes the microstructure of the fabric surface, increasing the contact area and roughness with the solid silicone, which is conducive to better penetration and adhesion of the solid silicone during the vulcanization process, and significantly enhances the bonding strength between the two. At the same time, preheating also makes the two in a similar temperature environment when entering the vulcanization stage. In the subsequent vulcanization process, heat can be transferred and distributed more evenly, avoiding uneven vulcanization caused by the large initial temperature difference between the two. If the fabric is not preheated, its temperature is much lower than that of the solid silicone. During vulcanization, a large amount of heat will be transferred to the fabric first, resulting in a different vulcanization speed of the solid silicone near the fabric side than other parts, resulting in inconsistent performance of various parts of the silicone product. Preheating together can avoid this situation and improve the stability of the quality of silicone products.

[0054] Furthermore, the vulcanization molding treatment of the solid silicone and the fabric also includes: the vulcanization molding conditions are a temperature of 160°C-220°C, a vulcanization time of 1 minute-5 minutes, and a pressure of 5Mpa-20Mpa. Preferably, the temperature of the vulcanization molding of the solid silicone and the fabric is 180°C, which is conducive to the solid silicone forming a uniform and dense network structure, laying a solid foundation for close bonding with the fabric. Similar to liquid silicone, the vulcanization time is adaptively adjusted according to the thickness of the silicone layer of the silicone product, so that the solid silicone has enough time to vulcanize and mold, while avoiding waste of resources and reduced production efficiency due to too long a time. Based on the actual requirements of silicone product vulcanization molding, the appropriate pressure is selected. Under the action of pressure, the solid silicone can flow more fully and fill the gaps in the fabric, increasing the contact area with the fabric, thereby significantly enhancing the bonding strength between the two; if the pressure is insufficient, the solid silicone cannot fill the gaps in the fabric, and the bonding strength between the solid silicone and the fabric is reduced, thereby affecting the physical properties of the silicone product; if the pressure is too high, it may damage the fabric or cause the solid silicone to overflow the mold, affecting the quality of the product.

[0055] Further, S100, placing the fabric and the silica gel in a mold, and performing vulcanization molding on the fabric and the silica gel to form a silica gel fabric composite further includes controlling the pressure gradient. Specifically, for solid silica gel, for example, 5 Mpa - 10 Mpa is applied in the initial stage of 0 - 30 s to promote the initial flow of the silica gel and its adhesion to the fabric. In the middle stage of 30 s - 2 minutes, the pressure is increased to 15 Mpa - 20 Mpa to promote the penetration of the silica gel into the fabric. In the later stage of 2 minutes to the end, the pressure is reduced to 8 Mpa - 12 Mpa and maintained stably until vulcanization is completed. Pressurizing in the initial stage ensures close contact between the silica gel and the fabric, expels the interfacial air, avoids bubbles or delamination, compensates for the change in fluidity of the silica gel during initial softening, and promotes the penetration of the silica gel into the fabric gaps. Pressurizing and maintaining a stable pressure in the middle stage enables the gradual formation of the strength of the silica gel itself. In the later stage, the pressure is slowly reduced or kept at a low pressure to prevent the shrinkage of the silica gel caused by a sudden drop in pressure and the peeling off of the fabric. The specific stepped pressure control can be set according to the actual situation, and the present application does not limit it here. By means of gradient pressure, the fabric is prevented from being crushed or the silica gel from flowing excessively due to a one-time high pressure. Pressurizing in stages can make the silica gel more fully fill the fabric voids and form a mechanical anchoring structure. For liquid silica gel, it also needs to control the pressure gradient during vulcanization. On the one hand, it can promote the combination of the liquid silica gel and the fabric, and on the other hand, it can reduce the concentration of internal stress. In addition, stepped pressure control is also beneficial for the liquid silica gel to better fill the mold, avoid insufficient local filling in the mold, and ensure the quality of the product.

[0056] Further, before laminating the solid silica gel and the fabric in the mold and closing the mold, it further includes performing plasma treatment on the contact surface between the solid silica gel and the fabric. Plasma such as argon or helium can be used, with a treatment power of 100 - 300 w and a treatment time of 30 s - 60 s. Plasma treatment can make the solid silica gel form a rough surface, thereby enhancing the bonding effect between the two during vulcanization molding.

[0057] Before placing the fabric and the silica gel in the mold and performing vulcanization molding on the fabric and the silica gel to form a silica gel fabric composite, it further includes pre-treating the fabric.

[0058] Further, the pre-treatment of the fabric includes: cleaning the fabric surface and performing surface treatment on the fabric. In the present application, whether vulcanizing and molding liquid silica gel or solid silica gel with the fabric, it is necessary to clean the surface of the fabric. The pre-treatment increases the surface polar groups (such as hydroxyl groups and carboxyl groups) by physical or chemical means, improves the surface energy, and thus enhances the interfacial bonding force between the silica gel and the fabric.

[0059] Specifically, when the silicone is liquid silicone, solvents such as alcohol are used to remove organic substances such as oil stains and dust on the fabric surface, and at the same time carry away dust particles, avoiding the generation of bubbles or delamination due to residual impurities during the vulcanization of liquid silicone, ensuring that the liquid silicone spreads evenly and forms a complete bonding interface. After the fabric surface is dried, the surface activity of the fabric is improved by plasma, flame treatment or coating with a primer; for heat-sensitive fabrics, such as synthetic fibers, high-energy particles in plasma (such as argon, helium, etc.) can be used to bombard the fabric surface, making the fabric surface rough and enhancing the bonding strength between the fabric and the liquid silicone; for natural fibers (such as cotton, linen) or high-temperature resistant synthetic fibers (such as aramid), the fabric surface is instantaneously oxidized by flame, burning off organic substances and forming polar groups, while locally carbonizing to increase roughness, making the fabric and the liquid silicone bond better; the primer forms an intermediate layer on the fabric surface through chemical reactions, connecting the fabric and the liquid silicone, improving the bonding strength. At the same time, the primer can relieve the stress generated by thermal expansion during the vulcanization process and improve the aging resistance of the silicone product.

[0060] When the silicone is solid silicone, impurities on the fabric surface can also be removed first by solvents such as alcohol to improve the bonding force between the solid silicone and the fabric. In addition, an adhesive can be coated between the solid silicone and the fabric. The adhesive can adjust the surface tension of the fabric to make it close to the surface energy of the solid silicone, promoting infiltration; at the same time, the adhesive can also fill the microscopic gaps between the fabric and the counter silicone, avoiding bonding defects caused by insufficient filling of the counter silicone; further, the adhesive layer can buffer the thermal stress generated by temperature changes after vulcanization and reduce the risk of interface cracking.

[0061] Furthermore, the fabric pretreatment also includes fabric drying; specifically, the cleaned and surface-treated fabric is put into a drying device, and the fabric drying conditions are drying at a temperature of 60°C - 80°C for 10 minutes - 20 minutes to remove the moisture on the fabric surface. The moisture on the fabric surface will affect the bonding effect between the liquid silicone and the fabric, and the evaporation of moisture during the vulcanization process may also cause defects such as pores and delamination in the silicone product. Drying the fabric can ensure a good bonding interface between the silicone and the fabric and improve the bonding strength.

[0062] Furthermore, injecting liquid silicone into the mold also includes controlling the injection speed of the liquid silicone at 10 ml / s - 30 ml / s and controlling the injection pressure at 5 Mpa - 15 Mpa. According to the size and shape of the mold, the injection speed of the liquid silicone is controlled; for molds with complex shapes, segmented injection can be adopted. First, inject a part of the liquid silicone at a slower speed to fill the key parts of the mold, and then appropriately increase the speed to complete the injection of the remaining part. By selecting the appropriate injection method and controlling the injection speed of the liquid silicone, it can ensure that the liquid silicone fills the mold evenly, avoiding situations of local underfilling or overfilling; stable injection pressure helps the liquid silicone form a good flow state in the mold, enabling the liquid silicone to be tightly combined with the fabric and improving the forming quality of the product.

[0063] Furthermore, after S100, placing the fabric and silicone in the mold and vulcanizing and molding the fabric and silicone to form a silicone fabric composite, and before S200, cutting the silicone fabric composite into the required size and shape, it also includes cooling the silicone fabric composite. After taking the silicone fabric composite out of the mold, it is placed in a cooling device and cooled at room temperature for 10 minutes - 30 minutes, so that the temperature of the silicone fabric composite gradually decreases and the internal structure is stable; by cooling the silicone fabric composite, it can avoid the product generating internal stress due to sudden temperature drop, resulting in deformation or cracking of the silicone fabric composite, and ensuring the stability of the product quality.

[0064] Furthermore, after S200, cutting the silicone fabric composite into the required size and shape, it also includes secondary vulcanization of the cut silicone fabric composite. The cut silicone fabric composite is placed in a secondary vulcanization device and subjected to secondary vulcanization at a temperature of 150°C - 180°C for 1 hour - 2 hours to further improve the performance of the product; secondary vulcanization makes the cross-linking reaction of the liquid silicone more complete, further improving the physical properties such as hardness, strength, and aging resistance of the product and extending the service life of the silicone product. It should be noted that secondary vulcanization is an optional step, and it can be selected whether to perform secondary vulcanization on the vulcanized and molded silicone fabric composite according to actual needs.

[0065] Furthermore, before S300, coating the adhesive layer on the silicone fabric composite, it also includes cleaning the silicone fabric composite. Specifically, use deionized water ultrasonic cleaning to remove the residual mold release agent on the surface of the composite, ensuring that there is no residual mold release agent on the surface when coating the adhesive layer subsequently, and avoiding poor adhesion of the adhesive layer.

[0066] The bonding layer is TPU or a hot melt adhesive film. Due to its own characteristics, silicone cannot be directly bonded to TPU (thermoplastic polyurethane elastomer) or a hot melt adhesive film. After the fabric and silicone are vulcanized and formed into a silicone product, the silicone product can be tightly pasted to TPU or a hot melt adhesive film, so that the silicone product can be bonded to the fabric through TPU or a hot melt adhesive film.

[0067] In an embodiment of the present application, when the silicone fabric composite is laminated with the bonding layer by a hot pressing process to form a silicone product, the conditions for hot pressing and curing are a temperature of 120°C - 160°C, a pressure of 0.5 Mpa - 2 Mpa, and a time of 10 s - 30 s. The temperature for hot pressing and curing TPU and the silicone fabric composite is 140°C - 150°C, and the temperature for hot pressing and curing the hot melt adhesive film and the silicone fabric composite is 120°C - 130°C. The temperature, pressure, and time can be selected according to the actual material of the bonding layer. The present application does not make any limitations here. After hot pressing is completed, the silicone product can be quickly cooled to below 50°C through a water cooling or air cooling device. Quick cooling can fix the shape of the bonding layer and prevent thermal deformation. After the water cooling or air cooling device quickly cools the silicone product, the silicone product is left stationary at room temperature to improve the final bonding strength.

[0068] In another embodiment of the present application, when the silicone fabric composite is laminated with the bonding layer by a high-frequency process to form a silicone product, the surface of the silicone fabric composite can be corona treated to increase the surface polarity, thereby enhancing the bonding effect between the silicone composite and the bonding layer. The silicone fabric composite and the bonding layer can select a suitable high-frequency process. The specific parameters are a frequency of 27.12 MHZ or 40.68 MHZ, a power of 1 - 5 KW (adjusted according to the product area), a time of 3 - 8 s, and a pressure of 0.3 - 1.0 MPa. After the high-frequency process is completed, it can be quickly cooled by water cooling or air cooling to form a stable bonding interface between the silicone fabric composite and the bonding layer, avoiding a decrease in the connection strength between the two.

[0069] In summary, a preparation process for a silicone product for bonding to fabric provided by the present invention includes:

[0070] Placing the fabric and silicone in a mold, and performing a vulcanization molding process on the fabric and silicone to form a silicone fabric composite;

[0071] Cutting the silicone fabric composite into the required size and shape;

[0073] Laminating the silicone fabric composite with the bonding layer by a hot pressing or high-frequency process to form a silicone product. The silicone product prepared by the preparation process of the present application improves the problem of poor bonding effect between the silicone product and the fabric in the prior art. The preparation process is simple and the cost is low.
