Description

Technical Field

[0001] The utility model relates to the technical field of Mylar sheets, in particular to a high-stability insulating and sealed Mylar sheet. Background Art

[0002] Mylar sheet is an insulating material commonly used in the packaging of electronic components, which can improve the safety performance of electronic components. Mylar sheet is a film made by heating dimethyl terephthalate and ethylene glycol with the assistance of relevant catalysts, undergoing ester exchange and vacuum polycondensation, and biaxial stretching. Mylar sheet has a variety of colors such as milky white, black, natural color, and transparent. According to different safety requirements, staff often paste multiple Mylar sheets of different thicknesses, or wrap more Mylar layers on electronic components that are prone to leakage to further improve the insulation effect.

[0003] A search revealed prior art publication number CN210956308U, which discloses a high-stability insulating Mylar sheet. The sheet comprises a first Mylar sheet insulation layer, a first metal layer, a second metal layer, and a second Mylar sheet insulation layer. A first heat dissipation adhesive layer is applied between the first Mylar sheet insulation layer and the first metal layer, a second heat dissipation adhesive layer is applied between the second Mylar sheet insulation layer and the second metal layer, and an adhesive layer is applied between the first and second metal layers. Both the first and second heat dissipation adhesive layers are filled with nano-electromagnetic shielding particles in a dendritic, needle-like, flake-like, or spherical shape, with a particle size of 0.1-1 μm. This invention exhibits excellent electromagnetic shielding and heat dissipation performance, a simple structure, easy production, and high efficiency.

[0004] However, the device and the prior art still have the following defects:

[0005] The existing Mylar sheet is one-piece molded, and the insulation effect of the Mylar sheet is poor. When the current is too large, it will cause certain damage to the Mylar sheet and cannot protect the electronic components well. The one-piece molded Mylar sheet has poor buffering effect and is easily damaged when subjected to external force collision, which reduces the use effect of the Mylar sheet and cannot meet the use requirements. Utility Model Content

[0006] The utility model aims to provide a high-stability insulating and sealing Mylar sheet.

[0007] To achieve the above objectives, the present invention provides the following technical solutions:

[0008] A high-stability insulating and sealing Mylar sheet comprises a Mylar sheet main body, wherein the Mylar sheet main body comprises a Mylar sheet base layer, an adhesive layer, an insulating layer, a protective layer, an antistatic layer and a wear-resistant layer, wherein the adhesive layer is arranged below the Mylar sheet base layer, the insulating layer is arranged above the Mylar sheet base layer, the protective layer is arranged above the insulating layer, the antistatic layer is arranged above the protective layer, and the wear-resistant layer is arranged above the antistatic layer, and the adhesive layer, Mylar sheet base layer, insulating layer, protective layer, antistatic layer and wear-resistant layer are pressed together in sequence from bottom to top.

[0009] By adopting the above technical solution, the adhesive layer adopts acrylic glue to ensure that the adhesive layer can be tightly adhered to the surface of the electronic component, thereby improving the fixing effect of the Mylar sheet. The insulating layer is composed of composite electromagnetic shielding particles composed of carbon nanotubes and graphene, which improves the current insulation effect, so that the Mylar sheet has good insulation shielding performance. The protective layer protects the base layer of the sheet. The anti-static layer reduces the static electricity of the Mylar sheet to prevent dust and impurities generated outside the electronic component from being statically attached to the surface of the component. The wear-resistant layer is made of wear-resistant silicone and has good wear resistance.

[0010] Furthermore, a first carbon fiber braided layer is provided at the lower end of the Mylar sheet base layer, a second carbon fiber braided layer is provided at the upper end of the Mylar sheet base layer, and the Mylar sheet base layer, the first carbon fiber braided layer and the second carbon fiber braided layer are integrated.

[0011] By adopting the above technical solution, the first carbon fiber braided layer and the second carbon fiber braided layer increase the toughness of the Mylar sheet base layer, so that the Mylar sheet can be bent appropriately, thereby improving the use effect of the Mylar sheet.

[0012] Furthermore, the protective layer includes an elastic frame and an elastic filling body, the elastic frame is arranged in a wave shape, and the elastic frame fits the antistatic layer and the insulating layer, and the elastic filling body is arranged in the gap between the elastic frame and the insulating layer and the antistatic layer.

[0013] By adopting the above technical solution, the elastic frame and the elastic filling body make the protective layer have an elastic buffering effect, which can buffer the external pressure when the Mylar sheet is hit, thereby protecting the Mylar sheet.

[0014] Furthermore, the upper end of the wear-resistant layer is provided with a raised block, there are at least six raised blocks, and the raised blocks are arranged at equal intervals on the upper end of the wear-resistant layer, and the raised blocks are arranged in a truncated cone shape.

[0015] By adopting the above technical solution, the raised block increases the contact area with the air around the upper end surface of the Mylar sheet, thereby increasing the heat exchange area and accelerating the heat dissipation of the Mylar sheet. When a foreign object contacts the Mylar sheet, it first contacts the raised block, and the raised block is worn first, thereby increasing the service life of the Mylar sheet.

[0016] Furthermore, a flexible heat-absorbing strip is provided inside the adhesive layer, and the flexible heat-absorbing strip and the adhesive layer are provided as a whole, and the flexible heat-absorbing strip is provided in a mesh shape inside the adhesive layer.

[0017] By adopting the above technical solution, the flexible heat-absorbing strip increases the heat absorption performance of the adhesive layer. When the adhesive layer is bonded to the electronic components, it can absorb and release the heat generated by the electronic components more quickly, avoiding the heat generated from accumulating in the bonding area and causing the temperature to rise rapidly, preventing the occurrence of local heating, and improving the use effect of the Mylar sheet.

[0018] Furthermore, a first release film is provided on the upper end of the Mylar sheet body, and the first release film is bonded to the wear-resistant layer; a second release film is provided on the lower end of the Mylar sheet body, and the second release film is bonded to the adhesive layer.

[0019] By adopting the above technical solution, the first release film and the second release film are one of PET fluoroplastic release film layer, PET matte release film layer or PE release film layer, which protect the upper and lower end surfaces of the unused Mylar sheet.

[0020] In summary, the beneficial technical effects of the present invention are:

[0021] The Mylar sheet is composed of a base layer, an adhesive layer, an insulating layer, a protective layer, an antistatic layer, and a wear-resistant layer. The adhesive layer, the base layer, the insulating layer, the protective layer, the antistatic layer, and the wear-resistant layer are pressed together from bottom to top to form a Mylar sheet. The adhesive layer can be tightly adhered to the surface of the electronic component to achieve fixation. The insulating layer is composed of composite electromagnetic shielding particles composed of carbon nanotubes and graphene, which improves the current insulation effect and makes the Mylar sheet have good insulation and shielding performance. The protective layer protects the base layer of the Mylar sheet. The antistatic layer reduces static electricity in the Mylar sheet to prevent dust and impurities generated outside the electronic component from being attached to the surface of the component by static electricity. The wear-resistant layer is made of wear-resistant silicone and has good wear resistance.

[0022] The use of raised blocks and flexible heat-absorbing strips increases the contact area between the upper end surface of the Mylar sheet and the air, thereby increasing the heat exchange area and accelerating the heat dissipation of the Mylar sheet. When foreign objects contact the Mylar sheet, they first contact the raised blocks and are worn first. The flexible heat-absorbing strips enhance the heat absorption performance of the adhesive layer. When the adhesive layer is bonded to the electronic components, it can absorb and release the heat generated by the electronic components more quickly, preventing the generated heat from accumulating in the bonding area and causing the temperature to rise rapidly. This prevents the occurrence of localized heating and increases the service life of the Mylar sheet.

[0023] An elastic frame and an elastic filling body are used, which make the protective layer have an elastic buffering effect. When the Mylar sheet is hit, the external pressure is buffered and the Mylar sheet is protected. BRIEF DESCRIPTION OF THE DRAWINGS
