Description

Technical Field

[0001] This utility model relates to the field of adhesive tape technology, specifically a flame-retardant and environmentally friendly sealing tape. Background Technology

[0002] Fireproof cloth, as the base material of flame-retardant cloth-based tape, is widely used in various industries. Traditional fireproof cloth is generally made of silicone rubber coated glass fiber cloth, which is calendered or impregnated with silicone rubber.

[0003] Existing flame-retardant cloth-based tapes, which use fire-retardant cloth as the base material, are susceptible to heat transfer to the adhesive coating when exposed to high temperatures. This causes the adhesive coating to lose its stickiness, resulting in the tape body falling off. Therefore, there is an urgent need to develop a flame-retardant and environmentally friendly sealing tape to meet the needs of practical use. Summary of the Invention

[0004] The purpose of this invention is to provide a flame-retardant and environmentally friendly sealing tape to solve the defect of existing flame-retardant tapes that, under high temperatures, conduct heat to the adhesive coating, causing the adhesive coating to lose its stickiness and resulting in the tape body falling off.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A flame-retardant and environmentally friendly sealing tape includes a tape body, which includes a base layer and an adhesive coating layer. The base layer and the adhesive coating layer are stacked sequentially from top to bottom to form a layered structure. The top of the base layer is provided with a woven layer made of glass fiber, and the glass fiber has a mesh structure. The mesh structure of the glass fiber has several gaps that can penetrate to the base layer. The tape body is also provided with a flame-retardant coating, which is applied to the surface of the woven layer.

[0007] As a further embodiment of the above description, the flame-retardant coating can extend into the interior of the base layer through the surface mesh structure of the woven layer, and the flame-retardant coating covers the surface of the woven layer and the base layer to form a film structure.

[0008] As a further option, the base layer can be made of any one of cotton cloth, synthetic fiber fabric, or plastic film, as described above.

[0009] As a further embodiment of the above description, the tape body also includes a release film layer, which is disposed on the bottom surface of the adhesive coating layer. The release film layer includes a release agent layer and a release paper layer.

[0010] As a further embodiment of the above description, the adhesive coating is composed of any one of butyl rubber hot melt pressure-sensitive adhesive, polyimide adhesive, and hot melt adhesive.

[0011] As a further embodiment of the above description, the flame-retardant coating is composed of a flame-retardant unsaturated polyester resin.

[0012] The beneficial effects of this utility model are as follows:

[0013] This application discloses a flame-retardant environmentally friendly sealing tape, which has a woven layer made of glass fiber between the flame-retardant coating and the base layer. The glass fiber has a mesh structure that can penetrate to the base layer. On the one hand, the glass fiber can cover the surface of the base layer to effectively isolate heat. On the other hand, the flame-retardant coating can fully extend to the surface of the base layer during the impregnation process through the mesh structure, further expanding the range of the flame-retardant film and effectively improving the flame-retardant performance of the tape.

[0018] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0019] Please see Figure 1-3 The present invention relates to a flame-retardant and environmentally friendly sealing tape, comprising a tape body 1, which includes a base layer 11 and an adhesive coating layer 12. The base layer 11 and the adhesive coating layer 12 are stacked sequentially from top to bottom in a layered structure. The top of the base layer 11 is provided with a woven layer 13 made of glass fiber, and the glass fiber has a mesh structure. The mesh structure of the glass fiber has several gaps that can penetrate to the base layer 11. The tape body is also provided with a flame-retardant coating layer 14, which is applied to the surface of the woven layer 13. The tape body 1 also includes a release film layer 15, which is disposed on the bottom surface of the adhesive coating layer 12. The release film layer 15 includes a release agent layer 151 and a release paper layer 152.

[0020] Specifically, the flame-retardant coating 14 extends into the interior of the base layer 11 through the surface mesh structure of the braided layer 13, and the flame-retardant coating 14 covers the surfaces of the braided layer 13 and the base layer 11 to form a film structure. A braided layer 13 made of glass fiber is provided between the flame-retardant coating 14 and the base layer 11. The glass fiber has a mesh structure that penetrates into the base layer 11. On the one hand, the glass fiber covering the surface of the base layer 11 effectively isolates heat; on the other hand, the flame-retardant coating 14, through the mesh structure, can fully extend to the surface of the base layer 11 during the impregnation process, further expanding the range of the flame-retardant film and effectively improving the flame-retardant performance of the tape.

[0021] Preferably, the base layer 11 is composed of any one of cotton cloth, synthetic fiber fabric, and plastic film. In this case, the cotton cloth and synthetic fiber fabric can fully penetrate the flame retardant coating 14 during the impregnation process, effectively improving the flame retardant performance of the tape.

[0022] Preferably, the adhesive coating 12 is composed of any one of butyl rubber hot melt pressure-sensitive adhesive, polyimide adhesive, and hot melt adhesive. The polyimide adhesive and hot melt adhesive form a strong adhesive layer after contact with the sealed box, with a temperature resistance range of -40 degrees Celsius to +120 degrees Celsius. The tape can still maintain good adhesion performance when exposed to high temperatures.

[0023] Preferably, the flame-retardant coating 14 is composed of a flame-retardant unsaturated polyester resin.
