[0002] At present, the label sheet made of polyvinyl chloride (PVC) has the advantage of good adhesion with other materials, but it is necessary to add a stabilizer when making a label sheet with PVC material. The agent contains heavy metals such as cadmium, barium or lead, which is easy to pollute the environment. Therefore, the current environmental protection regulations of various countries have stricter requirements on the amount of polyvinyl chloride.
[0003] In order to consider environmental protection issues, currently there are label sheets made of silicone material, but because the silicone rubber contains silicone oil, which itself is a type of release agent, it is difficult for the label sheet made of silicone material to use adhesives and other materials. The materials and objects are bonded and fixed. Although they can be fixed on the object by sewing, it is easy to cause damage to the label sheet due to sewing, and it is difficult to process, and the material of the object that can be sewn by the label sheet will also be limited (metal or thinner) Hard objects cannot be fixed by sewing), which will also make the application range of the label sheet smaller

Embodiment Construction
[0012] A preferred embodiment of the manufacturing method of the silicone label sheet with substrate of the present invention comprises the following steps:
[0013] Step 1: If figure 1 , figure 2 and Figure 4 As shown, a base material 10 and a color chip unit 30 are prepared. The base material 10 is made of high temperature resistant materials, such as leather, non-woven fabric, terry cloth, flannelette, etc. The base material 10 has a surface 11, A plurality of cilia 12 (or pores) protruding from the surface 11 and a consolidation surface 13 opposite to the surface 11 . The color chip unit 30 can be pre-filled on the top of a mold base 200, and has a plurality of color chips 32 and a back glue board 31 stacked on the color chips 32. The color chip unit 30 is made of silicon rubber , containing unreacted cross-linking agent.
[0014] Step 2: If figure 1 , figure 2 As shown, a liquid silicone layer 20 containing a cross-linking agent is coated on the surface 11 of the...

The invention discloses a method for manufacturing a silicon rubber label sheet with a base material. First, a base material and a color chip unit are prepared, and then a silicon rubber layer containing a cross-linking agent is coated on a surface of the base material to Form an embryo body, and then make the cross-linking agent contained in the silica gel layer of the embryo body produce an incomplete cross-linking reaction, and make the silica gel layer and the surface of the substrate produce an anchor, and finally the color chip unit It is laminated with the silicone layer of the embryo body, and is cured by heat and pressure to promote the cross-linking reaction between the silicone layer and the color chip unit, and a silicone label sheet with a base material can be obtained.
