Description

Technical Field

[0001] The utility model relates to the field of silicone rubber self-adhesive tapes, in particular to a high-temperature resistant insulating silicone rubber self-adhesive tape. Background Art

[0002] Self-adhesive tape is what we commonly call tape in our daily life, and silicone rubber self-adhesive tape is made of high-temperature resistant and stackable adhesive inorganic silicone rubber. It is a kind of self-adhesive tape. In the industrial production process, many devices work in a high-temperature environment and need to be pasted on the surface of the device to protect the device.

[0003] After searching, a utility model silicone rubber self-adhesive tape with a publication number of CN216711976U is found, which includes a substrate layer and a peeling protection layer arranged in sequence from top to bottom. The substrate layer is a strip-shaped structure with a rectangular cross section. A strip protrusion is arranged along the center line of the length direction of the upper surface of the substrate layer. The two sides of the strip protrusion transition with the upper surface of the substrate layer in an arc shape, and a dotted line mark is arranged on the upper surface of the strip protrusion; the length of the peeling protection layer is 5-8cm longer than the length of the substrate layer, and the width is 105-110% of the width of the substrate layer. The silicone rubber self-adhesive tape can easily determine the winding overlap position, and due to the existence of the strip protrusion, the extrusion force at the overlap is greater and the sealing is better; the peeling protection layer can better block dust, protect the substrate, and prevent glue overflow.

[0004] The existing silicone rubber self-adhesive tape itself does not have good fireproof and high temperature resistance performance, and the above-mentioned comparative case also does not have high temperature resistance performance. Therefore, when it is pasted on the device and works in a high temperature environment, it is easy to soften and flow or even melt, and the adhesion strength decreases, thus losing the protective effect on the device.

[0005] Therefore, it is necessary to invent a high temperature resistant insulating silicone rubber self-adhesive tape to solve the above problems. Utility Model Content

[0009] The first reinforcement layer and the second reinforcement layer are arranged inside the insulating silicone rubber self-adhesive tape body to improve the strength of the insulating silicone rubber self-adhesive tape body. A fire-resistant high-temperature layer is arranged inside the first reinforcement layer, a flame-retardant layer is arranged inside the fire-resistant high-temperature layer, and a base layer is arranged inside the flame-retardant layer.

[0010] Preferably, an inner ring is fixedly installed inside the first baffle, a connecting block is fixedly installed inside the inner ring, a threaded groove is opened inside the connecting block, a threaded column is movably connected inside the threaded groove, a fixing block is fixedly installed on one side of the threaded column, and the second baffle is fixed on one side of the fixing block.

[0011] Preferably, the first baffle is threadedly connected to the second baffle via a connecting block, and the connecting block is used in conjunction with a threaded column.

The fire-resistant high-temperature layer 10 and the flame-retardant layer 11 are provided so that the insulating silicone rubber self-adhesive tape body 1 has good fireproof ability, thereby avoiding softening and flowing or even melting, and the adhesion strength decreases, which loses the protection effect on the device. The base layer 13 is made of alkali-free glass fiber.

The first baffle 2 and the second baffle 8 can block both sides of the insulating silicone rubber self-adhesive tape body 1, thereby effectively preventing dust from entering the inside from both sides of the insulating silicone rubber self-adhesive tape body 1, and ensuring the adhesion effect of the insulating silicone rubber self-adhesive tape body 1, so that it can be used normally.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, the first baffle 2 is threadedly connected to the second baffle 8 via a connecting block 4, and the connecting block 4 is used in conjunction with a threaded column 6.

[0031] like Figure 4 As shown, the material of the first reinforcement layer 9 and the second reinforcement layer 12 is a fiber-reinforced composite material, and the first reinforcement layer 9 and the second reinforcement layer 12 make the insulating silicone rubber self-adhesive tape body 1 have a certain strength during use, thereby avoiding being torn and damaged, which would affect its normal use.

When the insulating silicone rubber self-adhesive tape body 1 is pasted on the device, the high temperature generated by the device passes through the fire-resistant high-temperature layer 10 and the flame-retardant layer 11, so that the insulating silicone rubber self-adhesive tape body 1 has good fire resistance, thereby avoiding softening and flowing or even melting, and the adhesion strength decreases, which loses the protection effect on the device. At the same time, the adhesive layer 14 is made of acrylic adhesive, and the flame retardant performance of acrylic adhesive is good. In this way, the use process of the high-temperature resistant insulating silicone rubber self-adhesive tape is completed.
