Description

Technical Field

[0001] The utility model relates to the technical field of adhesives, in particular to a bend-resistant and flame-retardant conductive adhesive. Background Art

[0002] Conductive adhesive is an adhesive that exhibits a certain degree of conductivity after curing or drying. It can connect a variety of conductive materials, creating an electrical path between the connected materials. Conductive adhesive has become an essential new material in the electronics industry, widely used in the packaging and bonding of electronic components and assemblies such as liquid crystal displays, light-emitting diodes, integrated circuit chips, and printed circuit board assemblies. Conductive adhesives are available in a wide variety of types and can be categorized based on their application: general-purpose conductive adhesives and specialty conductive adhesives. General-purpose conductive adhesives are primarily used for basic conductive connections, while specialty conductive adhesives are designed and optimized for specific application requirements. Conductive adhesives typically consist of a base resin and a conductive filler. The base resin's bonding action binds the conductive particles together, forming a conductive path. Advantages of conductive adhesives include simple processing, ease of operation, improved production efficiency, and the avoidance of environmental pollution caused by the heavy metal lead in tin-lead solder. With the development of society, conductive adhesives are increasingly used when bonding electronic components.

[0003] Existing devices, such as CN201830614U, include a conductive tape comprising a base tape with a strip-shaped conductive adhesive layer disposed thereon. The device is characterized by at least one strip-shaped non-conductive adhesive layer disposed on the base tape adjacent to the conductive adhesive layer. This device addresses the technical issue of poor adhesive properties of existing conductive tapes, improving the adhesive strength while maintaining the performance of the conductive tape.

[0004] When workers need to bond electronic components, they adhere conductive glue to the interfaces of the electronic components so that the conductive glue can bond the electronic components. However, the conductive glue may encounter angle problems during use, causing the conductive glue to break after a certain period of time in the bent state, thereby causing the conductive glue to be unable to continue to be used.

[0007] Preferably, the surface of the safety patch is provided with a flame retardant device, and the flame retardant device includes a melamine cyanurate coating, and the melamine cyanurate coating is fixedly connected to the surface of the safety patch. The melamine cyanurate coating can cooperate with the safety patch to achieve the purpose of limiting the melamine cyanurate coating.

[0008] Preferably, the surface of the melamine cyanurate coating is fixedly connected with a melamine coating, and the melamine cyanurate coating is a derivative of the melamine coating. The melamine cyanurate coating can be matched with the melamine coating to produce a large amount of non-combustible gas during combustion for flame retardancy.

[0009] Preferably, a fifth patch is fixedly connected to the surface of the melamine coating, and fly ash is fixedly connected to the surface of the fifth patch. The fifth patch can cooperate with the fly ash to achieve the purpose of heat absorption and flame retardancy.

[0010] Preferably, the surface of the fifth patch is fixedly connected to the fourth patch, a cavity is opened inside the fourth patch, and coolant is stored inside the cavity. The fourth patch can cooperate with the fifth patch to achieve the purpose of fixing the fourth patch to store coolant.

[0011] Compared with the prior art, the advantages and positive effects of the present invention are:

[0012] 1. In the utility model, by setting a bending-resistant device, when the worker needs to adhere the bent part of the electronic component, it is effectively convenient for the conductive glue to adhere the electronic component and use the equipment. The equipment adheres the electronic component and conducts electricity to achieve the purpose of maintaining the power supply of the electronic component. When the worker bends the conductive glue, the worker will apply stress to the safety patch.

[0025] In this embodiment, the melamine cyanurate coating 46 can cooperate with the safety patch 36 to achieve the purpose of limiting the melamine cyanurate coating 46 .

[0026] In this embodiment: the surface of the melamine cyanurate coating 46 is fixedly connected to the melamine coating 45. The melamine cyanurate coating 46 is a derivative of the melamine coating 45. The melamine cyanurate coating 46 can cooperate with the melamine coating 45 to produce a large amount of non-combustible gas for flame retardancy during combustion.

[0027] Specifically, the fifth patch 44 is fixedly connected to the surface of the melamine coating 45 , and the fly ash 43 is fixedly connected to the surface of the fifth patch 44 .

[0031] Working principle: By setting the anti-bending device 3, when the worker needs to adhere the bending part of the electronic component, it is effective to facilitate the conductive glue to adhere the electronic component, and use the device. The device adheres the electronic component and conducts electricity to achieve the purpose of maintaining the power supply of the electronic component.

The fly ash 43 will absorb part of the heat under the influence of the high temperature. When the third patch 33 and the fifth patch 44 burn, the flame will react with the melamine coating 45 and the melamine cyanurate coating 46 to produce non-combustible gas. By setting the flame retardant device 4, the spontaneous combustion of the conductive adhesive can be effectively reduced, the service life of the electronic components and the conductive adhesive is increased, and the flame retardancy of the conductive adhesive is improved.
