A waterproof structure 2 includes a first silicone rubber layer 21 disposed on one side of the fabric structure 1 , a plurality of silicone rubber connecting portions 22 extending from the first silicone rubber layer 21 into the fiber holes 11 , and a silicone rubber layer 22 . The connecting portion 22 extends to the second silicone layer 23 on the side of the fabric structure 1 away from the first silicone layer 21 , and the waterproof structure 2 is made of a mixture of silicone 241 , silicon dioxide 242 , silicone oil 243 and platinum 244 ;

A positioning member 3 is disposed on the side of the waterproof structure 2 away from the fabric structure 1 , specifically, can be disposed on the side of the first silicone layer 21 or the second silicone layer 23 away from the fabric structure 1 , in this embodiment, the The second silicone layer 23 is disposed on the side away from the fabric structure 1 for implementation.

And the manufacturing method of the silicone cloth of the present invention, its main steps include:

(a) using a refining device to mix silica gel, platinum, silica and silicone oil to form a waterproof structure;

(b) using a calendering device to combine the waterproof structure with a cloth structure to form a A first silicone layer on one side of the fabric structure, a plurality of silicone connecting portions extending from the first silicone layer into the fiber holes of the fabric structure, and a silicone connecting portion extending from the silicone connecting portion away from the fabric structure a second silicone layer on one side of the first silicone layer;

(c) combining a positioning piece on the side of the waterproof structure away from the cloth structure;

(d) using a baking device to dry and shape the cloth structure, the waterproof structure and the positioning member.

When constructed by the above components, it can be clearly seen that the cloth structure 1 is made of cotton, linen and other materials with fiber holes 11 , and the positioning member 3 is a plastic film that can provide stickiness or anti-slip effect. The corresponding types of the above-mentioned elements are only examples of preferred embodiments, and all types with the same function belong to the scope of the present invention, and are not limited to the above-mentioned examples.

From the above description, the structure of the present technology can be understood, and according to the corresponding cooperation of this structure, the manufacturing method is simple and fast, the cost is low, and the finished product is light in weight, has no silicone appearance, and is suitable for food-grade commodities. and other advantages, and the detailed explanation will be described below.

Please also refer to the first to seventh figures, which are the perspective views to the implementation schematic diagram (3) of the preferred embodiment of the present invention. It can be clearly seen from the fifth figure and step (a) that the silicone rubber of the present invention is At the beginning of the production, silicone rubber 241, silicon dioxide 242, silicone oil 243 and platinum 244 are first added to the refining device 4 for mixing and refining. The refining device 4 is an example of an open mill, and the silicone oil 243 is Silicone polymer in liquid phase has the highest viscosity index among all oils (can exceed 500 centipoise), high chemical stability and high temperature resistance. When combined with fabric structure 1, a small amount of use can be It can be firmly bonded to the surface of the fabric structure 1, and the silicone oil 243 has the characteristics of a mold release agent, which is not easy to stick to the metal, so the surface is clean and bright after the mold is released, and the texture is clear; the silicon dioxide 242 has strong water absorption, adding the silicone gel 241 Afterwards, it can be used to adjust the water resistance of the silicone rubber 241; after platinum 244 is combined with the silicone rubber 241, the silicone rubber 241 can reach the medical or food grade.

As shown in Figure 5, Figure 6 and step (b), after the refining device 4 is used for uniform mixing, the produced waterproof structure 2 is combined with the cloth structure 1 through the calendering device 5. After calendering, the waterproof structure 2 is The first silicone layer 21 is first added to one side of the fabric structure 1 to form a first silicone layer 21. After being squeezed by the calendering device 5, the first silicone layer 21 will penetrate into the fiber holes 11 of the fabric structure 1 to form the silicone connecting portion 22. The calendering device 5 Continue to squeeze, so that the silicone rubber connecting portion 22 passes through the fiber hole 11 and spreads out on the other side surface of the cloth structure 1 , and forms a second silicone rubber layer 23 . Since the waterproof structure 2 is made of silicone 241 is a basic improvement, so it can pass through the fabric structure 1, and only needs to be processed once, that is, it is formed on both sides of the fabric structure 1.

As shown in Figure 7, the positioning member 3 is then attached to the outside of the waterproof structure 2, and finally the combined fabric structure 1, waterproof structure 2 and positioning member 3 are sent to the baking device to be hardened and shaped. The reason why the fabric structure 1 absorbs water is that it has fiber holes 11, and the present invention has used the waterproof structure 2 to penetrate into the fiber holes 11, so that the final product can have a water-repellent effect without adding an additional water-repellent auxiliary. , the fiber holes 11 of the fabric structure 1 that are often attached to bacteria have been blocked, and the main component of the waterproof structure 2 is the silicone 241 with high oxygen permeability, so the fabric structure 1 can be indirectly achieved. Antibacterial effect, and because only one time Processing, the overall production time is shorter, because less raw materials are used, so that there is almost no silicone feeling in terms of visual effect or touch, and the cost can also be reduced. The weight of the silicone cloth is also lighter, and it can be matched with positioning parts 3 Provide anti-slip or paste function.

Please also refer to Figures 8 to 10, which are another perspective view to a flow chart of another preferred embodiment of the present invention. It can be clearly seen from the figures that the present embodiment and the above-mentioned embodiment For the sake of similarities, only the waterproof structure 2a is changed to a mixture of silicone rubber 241a, silicon dioxide 242a, silicone oil 243a and peroxide 245a, and at least one concave-convex graphic portion 31a is formed on the surface of the silicone cloth. The graphic portion 31a is formed on the side of the positioning member 3a away from the waterproof structure 2a. In addition, in step (a), the refining device includes a mixing mechanism, so as to use the mixing mechanism to perform the mixing action. In this embodiment, the The mixing mechanism takes a lilac machine as an example, and in step (c), a rolling machine is used to combine the waterproof structure 2a and the positioning member 3a, and simultaneously generate the concave-convex graphic portion 31a. The steps of the specific manufacturing method mainly include: (a) firstly use a mixing mechanism to mix silicone rubber, peroxide, silicon dioxide and silicone oil, and then use a refining device to make a waterproof structure; (b) use a calendering device The device combines the waterproof structure with a fabric structure to form a first silicone layer on one side of the fabric structure, a plurality of silicone connectors extending from the first silicone layer to the fiber holes of the fabric structure, and a second silicone rubber layer extending from the silicone rubber connecting portion to the side of the fabric structure away from the first silicone rubber layer; (c) using a rolling machine to combine the waterproof structure and the positioning member, and place the positioning member away from the first silicone rubber layer A concave-convex graphic portion is formed on one side of the waterproof structure; (d) drying the cloth structure, the waterproof structure and the positioning member by a baking device.

According to the composition of the above waterproof structure 2a, the original platinum is replaced with peroxide 245a. Therefore, if the silicone cloth in this case is not used for food-grade products, the peroxide 245a with lower material cost can be used, and The mixing mechanism can be used to mix first, and then the refining device is used for mixing, and the mixing mechanism of this embodiment uses a Lena machine, which is suitable for mixing a large amount of raw materials to speed up the process speed, and the rolling machine can be adjusted and changed. The concave-convex graphic portion 31a is imprinted on the positioning member 3a.

Please also refer to the eleventh figure, which is a schematic structural diagram of another preferred embodiment of the present invention. It can be clearly seen from the figure that this embodiment is similar to the above-mentioned embodiment, and only the concave and convex graphic parts are 31b is formed on the side of the waterproof structure 2b away from the positioning member 3b. Since the first silicone layer 21b of the waterproof structure 2b is inevitably a little sticky due to the silicone material, especially when the silicone material is in contact with the silicone material, it is more likely to occur, but as long as the contact area between the silicone materials is reduced, it can be effectively reduced. Necessary adhesive issues. The silicone cloth in this case has a wide range of uses. For example, when it is used to make a bag body, the inner layer of the bag is the first silicone layer 21b. Therefore, a concave and convex graphic portion 31b is formed on the surface of the first silicone layer 21b, so as to reduce the undesired effect of the inner layer of the bag. Adhesion is necessary, and the concave-convex graphic portion 31b in this embodiment is presented in a state of oblique stripes. When the first silicone layers 21b are in contact with each other due to the folding of the silicone sheet, the concave-convex graphic portion 31b is in contact with each other in a crossed state. In this way, the contact area is minimized to reduce unnecessary adhesion problems.
