Description

Technical Field

[0001] The utility model belongs to the technical field of double-sided tapes, and particularly relates to a tensile and flame-retardant double-sided tape. Background Technique

[0002] A double-sided tape is a roll-shaped adhesive tape made by using paper, cloth, or plastic film as the base material and evenly coating an elastomeric pressure-sensitive adhesive or a resin-based pressure-sensitive adhesive on the above-mentioned base material. It mainly consists of three parts: a base material, an adhesive, and a release paper (film) or silicone oil paper; ordinary double-sided tapes use cotton paper, non-woven fabric, foam, acrylic foam, etc. as the base material.

[0003] However, due to their own limitations, the tensile strength and flame retardancy of these base materials are seriously insufficient, which greatly limits the scope of use of double-sided tapes. Content of the Utility Model

[0004] The purpose of the utility model is to provide a tensile and flame-retardant double-sided tape to solve the problems raised in the above background technique.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is a tensile and flame-retardant double-sided tape, which includes a base layer. Tensile layers are arranged on both the top and bottom of the base layer. An insulating layer is arranged on the side of the tensile layer away from the base layer. A flame-retardant layer is arranged on the side of the insulating layer away from the tensile layer. An adhesive layer is arranged on the side of the flame-retardant layer away from the insulating layer. A release paper is arranged outside the adhesive layer. Both the base layer and the adhesive layer use a PET base film as the base material layer.

[0007] The tensile layer is made of a base material formed by thermocompression of a PTFE film and an ETFE film, and tensile nylon threads are embedded on the surfaces of the PTFE film and the ETFE film; by setting the tensile layer, the tensile strength is improved by using the PTFE film, the ETFE film and the tensile nylon threads, the service life of the entire double-sided tape is improved, and the stability of the double-sided tape is also improved, ensuring more reliable and effective use during the process and facilitating people's operation and use.

[0008] The insulating layer is made of asbestos fiber.

[0009] The flame-retardant layer is made of a polyethylene film, and chlorinated rubber is coated on the surface of the polyethylene film. The insulating layer is adhesively connected to the tensile layer and the flame-retardant layer through silicone rubber, and several flame-retardant particles are embedded in the silicone rubber; by setting the flame-retardant layer and the insulating layer, the direct combustion of the flame is isolated by using the polyethylene film, the released chlorine gas during heating by the set chlorinated rubber is used for flame retardancy, the set flame-retardant particles are further used for flame retardancy, and the asbestos fiber plays a role in heat insulation to avoid temperature transfer, and the flame retardancy of the double-sided tape is significantly improved.

[0010] The material of the adhesive layer is acrylic glue, and several flame retardant particles are embedded in the acrylic glue. The width of the release paper is the same as that of the adhesive layer, and it directly covers the acrylic glue on the surface layer.

[0011] The utility model has the following beneficial effects:

[0012] By setting a tensile layer, a flame retardant layer and a heat insulation layer, the utility model uses a polyethylene film to isolate the direct combustion of the flame. Chlorinated rubber is set to release chlorine when heated for flame retardancy, and the set flame retardant particles are further used for flame retardancy. Asbestos fiber plays a role in heat insulation to avoid temperature transmission. The double-sided tape significantly improves the flame retardant ability, and the PTFE film, ETFE film and tensile nylon thread improve the tensile strength, improve the service life of the whole double-sided tape, and also improve the stability of the double-sided tape, ensuring more reliable and effective use in the process and facilitating people's operation and use.

[0021] Please refer to Figure 1 As shown, the present utility model is a tensile and flame-retardant double-sided tape, which includes a base layer 1. Tensile layers 2 are provided on both the top and bottom of the base layer 1. An insulating layer 31 is provided on the side of the tensile layer 2 away from the base layer 1. A flame-retardant layer 3 is provided on the side of the insulating layer 31 away from the tensile layer 2. An adhesive layer 4 is provided on the side of the flame-retardant layer 3 away from the insulating layer 31. A release paper 5 is provided on the outside of the adhesive layer 4. Both the base layer 1 and the adhesive layer 4 are based on a PET base film as the base material layer.

[0022] The tensile layer 2 is made of a material formed by thermocompression of a PTFE film and an ETFE film as the base material, and tensile nylon threads are embedded on the surfaces of the PTFE film and the ETFE film; by providing the tensile layer 2, the tensile strength is improved by using the PTFE film, the ETFE film and the tensile nylon threads, the service life of the entire double-sided tape is increased, and the stability of the double-sided tape is also improved, ensuring more reliable and effective use during the process and facilitating people's operation and use.

[0023] The insulating layer 31 is made of asbestos fiber.

[0024] The flame-retardant layer 3 is made of a polyethylene film, and chlorinated rubber is coated on the surface of the polyethylene film. The insulating layer 31 is adhesively connected to the tensile layer 2 and the flame-retardant layer 3 through silicone glue, and several flame-retardant particles are embedded in the silicone glue; by providing the flame-retardant layer 3 and the insulating layer 31, the direct combustion of the flame is isolated by the polyethylene film, the released chlorine gas during heating by the provided chlorinated rubber is used for flame retardancy, the provided flame-retardant particles are further used for flame retardancy, and the asbestos fiber plays a role in heat insulation to avoid temperature transfer, and the flame retardancy of the double-sided tape is significantly improved.

[0026] It should be noted that during use, the release paper 5 needs to be torn off, and then the double-sided tape is pasted on the outer side of the item to be pasted, so that the adhesive layer 4 contacts the item. The tensile layer 2 can improve the tensile strength of the double-sided tape through the PTFE film, ETFE film and tensile nylon thread, and can be torn arbitrarily, reducing the probability of the double-sided tape breaking; when encountering an open flame, the flame retardant layer 3 uses the polyethylene film to isolate the direct combustion of the flame, and at the same time uses chlorinated rubber to release chlorine for flame retardance. The heat insulation layer 31 has a heat insulation effect to avoid temperature transfer, effectively preventing the double-sided tape from burning.
