Description

Technical Field

[0001] This utility model relates to the field of Mylar sheet technology, and more specifically, to an insulating Mylar sheet. Background Technology

[0002] Mylar film is a thin film made by heating dimethyl terephthalate and ethylene glycol with the assistance of a relevant catalyst, followed by transesterification, vacuum polycondensation, and biaxial stretching. It has the characteristics of dimensional stability, heat and cold resistance, moisture and water resistance, chemical corrosion resistance, and insulation, and is widely used in the electronics, communications, micro motors, computers, electrical appliances, and other industries.

[0003] However, the shapes of the areas that need to be covered with Mylar film vary, so the Mylar film needs to be cut before use. Cutting Mylar film requires cutting equipment, but the cutting equipment is not easy to carry and the cutting process is inconvenient.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an insulating Mylar sheet, which improves the applicability of Mylar sheet through a new structural design.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an insulating Mylar sheet, comprising a Mylar sheet body, the Mylar sheet body comprising a plurality of base layers and a plurality of peeling blocks, the base layers and peeling blocks being fixedly connected by a plurality of connecting blocks I, the base layers having a plurality of slits I at the peripheral wall of the peeling blocks, each of the plurality of connecting blocks I having a breakage groove I on one side, adjacent base layers being fixedly connected by a plurality of connecting blocks II, each of the plurality of connecting blocks II having a breakage groove II on the same side of the breakage groove I, a slit II being formed between adjacent base layers and the plurality of connecting blocks II, the side of the Mylar sheet body away from the breakage groove I being coated with an adhesive layer, the side of the adhesive layer away from the Mylar sheet body being covered with a release layer, the release layer having greater extensibility than the Mylar sheet body.

[0007] The present invention is further configured such that: the peeling block is placed between several circumferentially arranged slits, and several slits and connecting blocks are alternately arranged along the length and width directions of the Mylar sheet body, respectively; the thickness of the peeling block is the same as the thickness of the base layer and is located on the same horizontal plane.

[0008] The present invention is further configured such that: a plurality of connecting blocks are arranged in a circular array between the base layer and the stripping block, the thickness of the connecting blocks and the connecting blocks is the same as the thickness of the base layer, and the plurality of connecting blocks and the connecting blocks are all located on the same horizontal plane as the base layer.

[0009] The present invention is further configured such that: the aforementioned base layer, connecting block one, peeling block, and connecting block two are all integrally formed by cutting several slits one and slit two on the Mylar sheet body.

[0010] The present invention is further configured such that: each of the plurality of the first breakage grooves is integrally formed after being stamped on the surface of the plurality of first connecting blocks, and each of the plurality of second breakage grooves is integrally formed after being stamped on the surface of the plurality of second connecting blocks.

[0011] The present invention is further configured such that the length and width of the Mylar sheet body are the same as the length and width of the adhesive layer and are smaller than the length and width of the release layer.

[0012] In summary, this utility model has the following beneficial effects: Force is applied to several connecting blocks located between adjacent base layers according to the desired shape of the area to be covered with Mylar sheet, thereby causing the two breakage grooves on the connecting blocks to bend and break. Simultaneously, a peeling block is selected at a suitable position according to the desired opening location, and force is manually applied to several connecting blocks on the periphery of the peeling block, thereby causing the breakage groove on the connecting blocks to bend and break. At this time, while the release layer is being torn off, the separated base layer and peeling block are separated from the Mylar sheet body, thus obtaining the Mylar sheet body with the desired shape and opening, improving the applicability of the Mylar sheet body.

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] Example: An insulating Mylar sheet, such as Figures 1-3As shown, the Mylar sheet body 1 includes a layer of Mylar sheet 1, which is made of PET material. PET material is an excellent insulating material, which enables the Mylar sheet body 1 to provide good electrical insulation. It is suitable for industries such as electronics, communications, micro motors, computers, electrical appliances, and electronics. The Mylar sheet body 1 includes several square base layers 2 and several square peeling blocks 3. The thickness of the peeling blocks 3 is the same as the thickness of the base layers 2 and they are located on the same horizontal plane. The base layers 2 are cut with several L-shaped slits 4 arranged in a circular array by a stamping and cutting machine. The side length of the peeling blocks 3 is smaller than the side length of the base layers 2. The peeling blocks 3 are placed between the several circularly arranged slits 4. A connecting block 5 is arranged in a circular array around the peeling blocks 3. One end of the connecting block 5 is fixedly connected to the peripheral wall of the peeling block 3. The ends of the several connecting blocks 5 away from the peeling blocks 3 are fixedly connected to the base layers 2, thereby fixing the peeling blocks 3 in the middle of the base layers 2.

[0019] like Figures 1-3 As shown, the thickness of connecting block 5 is the same as the thickness of base layer 2. Several connecting blocks 5 and several base layers 2 are located on the same horizontal plane. One side of several connecting blocks 5 is stamped with a V-shaped break groove 6 by a stamping machine. The break groove 6 makes it easy for connecting blocks 5 to break after being bent under force. When the connecting blocks 5 around the peeling block 3 are all bent and broken, the peeling block 3 separates from the base layer 2. Adjacent base layers 2 are fixedly connected together by several connecting blocks 7. The thickness of connecting blocks 7 is the same as the thickness of base layer 2. Several connecting blocks 7 are located on the same horizontal plane as several base layers 2. On a horizontal plane, a straight slit 9 is opened between adjacent base layers 2 and several connecting blocks 7. Several slits 9 and connecting blocks 7 are alternately arranged along the length and width directions of the Mylar sheet body 1. A V-shaped break groove 8 is punched on the same side of several connecting blocks 7 located at the break groove 6 by a stamping machine. The break groove 8 makes it easy for the connecting blocks 7 to break after being bent under force. When several connecting blocks 5 around the base layer 2 are bent and broken, the base layer 2 is separated from the Mylar sheet body 1. The shape of the Mylar sheet body 1 can be easily changed without cutting equipment.

[0020] like Figures 1-3As shown, several base layers 2, connecting blocks 1 5, peeling blocks 3, and connecting blocks 2 7 are integrally formed by cutting several slits 1 4 and slits 2 9 on the Mylar sheet body 1. Several breakage grooves 1 6 are integrally formed by stamping on the surface of several connecting blocks 1 5. Several breakage grooves 2 8 are integrally formed by stamping on the surface of several connecting blocks 2 7. A layer of adhesive 10 is coated on the side of the Mylar sheet body 1 away from the breakage grooves 1 6. This adhesive 10 is made of glue. The adhesive 10 can effectively cover and fix the Mylar sheet body 1 onto the required area. A release layer 11 is applied to the side of the adhesive 10 away from the Mylar sheet body 1. This release layer 11 is made of TPU material. TPU material has better extensibility than PET, so the release layer 11... The extensibility is greater than that of the Mylar sheet body 1, so that the release layer 11 can maintain the structural integrity even after the connecting block 5 and the connecting block 7 break when it is bent together with the Mylar sheet body 1. The length and width of the Mylar sheet body 1 are the same as the length and width of the adhesive layer 10 and smaller than the length and width of the release layer 11. The side of the release layer 11 near the adhesive layer 10 is coated with an anti-adhesive agent, thereby reducing the peel strength of the release layer 11. The release layer 11 can be easily separated from the adhesive layer 10 through the part of the release layer 11 that extends beyond the edge of the polyurethane body. At the same time, the release layer 11 will carry the separated base layer 2 and the release layer away from the Mylar sheet body 1, thereby obtaining the Mylar sheet body 1 with the required area and opening position, improving the applicability of the Mylar sheet body 1.

[0021] Working principle: When a force is manually applied to several connecting blocks 7 located between adjacent base layers 2, the breakage grooves 8 on several connecting blocks 7 will bend and break under the force. Since the extensibility of the release layer 11 is greater than that of the Mylar sheet body 1, the release layer 11 will not break while bending along with the Mylar sheet body 1. When a force is manually applied to several connecting blocks 5 located on the periphery of the peeling block 3, the breakage grooves 6 on several connecting blocks 5 will bend and break under the force, thereby separating the peeling block 3 from the Mylar sheet body 1. When the release layer 11 is torn off, it will separate the separated base layer 2 and peeling block 3 together with the Mylar sheet body 1. The Mylar sheet body 1 after adjusting the size and opening can be applied to the required area through the adhesive layer 10.

All technical solutions falling within the scope of this utility model's concept are protected.
