As shown in fig. 1, an embodiment of the present invention provides a wave-absorbing insulating sheet 100 convenient for fool-proof detection, which includes: the insulation sheet comprises an insulation sheet body 10, a buffer layer 20, a first adhesive layer 30 and a second adhesive layer 40.
The insulation sheet body 10 has an electromagnetic shielding function, and forms a base material portion of the wave-absorbing insulation sheet of this embodiment. Therefore, when the wave-absorbing insulating sheet of the embodiment is applied to a notebook computer, the insulating sheet body 10 can absorb electromagnetic waves that interfere with the operation of the electronic device.
Specifically, the insulation sheet body 10 includes: an electromagnetic wave absorbing layer 11 and a light shielding layer 12 bonded to one surface of the electromagnetic wave absorbing layer 11. Wherein, electromagnetism wave-absorbing layer 11 is including range upon range of setting gradually: bottom layer, metal magnetic body powder layer and two-sided glue film. In one embodiment, the metallic magnetic powder layer includes: the inferior gram force rubber layer body and the metal particle who fills in inferior gram force rubber layer body. Thus, the insulating sheet body 10 can function as an electromagnetic shield by the metal magnetic powder layer.
The shading layer 12 is formed by bonding a double-sided adhesive layer on one side of the electromagnetic wave absorbing layer 11. The light shielding layer 12 has a light-tight property, so that the influence of external light transmission on the visual detection result can be avoided during subsequent visual detection. In one embodiment, the light shielding layer 12 may be a black PET film layer of type X30.
The buffer layer 20, the first adhesive layer 30 and the second adhesive layer 40 are all bonded on the light-shielding layer 12. Wherein, this embodiment is through carrying out rational arrangement to buffer layer 20 and viscose layer, when satisfying the bonding demand, can also rationally keep away the position, has made things convenient for the subsides dress of inhaling the wave-insulating piece.
In this embodiment, the buffer layer 20 and each adhesive layer are optimally arranged as follows: the first adhesive layer 30 is located in the middle region of the light shielding layer 12; the buffer layer 20 is arranged close to the long side L of one side of the light shielding layer 12 and at least covers a right-angle area formed by the long side and the short sides of the two sides; the second adhesive layer 40 is disposed close to the short side W on one side of the light-shielding layer 12, and the short side on one side of the second adhesive layer 40 is disposed close to the buffer layer 20, and the long side on one side is disposed close to the first adhesive layer 30.
Specifically, the first adhesive layer 30 and the second adhesive layer 40 are used to attach the wave-absorbing insulating sheet of this embodiment to corresponding positions of the motherboard of the notebook computer. Adopt different viscose layers, when being convenient for keep away a design, can also compromise the subsides dress requirement in different dress areas (for example, different areas are to the requirement of glue film viscidity, size etc.).
The middle region of the first adhesive layer 30 is located at a position where the first adhesive layer 30 is approximately located at a midpoint of the length and the width of the light shielding layer 12. The first adhesive layer 30 includes: a PET middle layer and acrylic adhesive layers combined on the two surfaces of the PET middle layer. In one embodiment, the first adhesive layer 30 may be a double-sided adhesive tape with a type TESA 61390.
In consideration of increasing the bonding force between the edge of the wave-absorbing insulation sheet and the main board, the second adhesive layer 40 is made of AB double-sided adhesive tape. At this time, the adhesion of one surface of the AB double-sided tape bonded to the light-shielding layer 12 is larger than that of the other surface. Specifically, the AB double-sided tape includes: the adhesive comprises a polyester film middle layer, silica gel combined on one side of the polyester film middle layer and a silica gel combined on the other side of the polyester film middle layer. Therefore, firm combination between the edge of the wave-absorbing insulating sheet and the mainboard is ensured. In one embodiment, the AB double-sided adhesive tape can be 3M 9119-50.
In addition, the first adhesive layer 30 and the second adhesive layer 40 have a thickness difference therebetween, so as to match with the height difference of the mounting position.
Considering that the corner region formed by the long side and the short side of the light shielding layer 12 is a load bearing region, the buffer layer 20 covers at least the right-angle region formed by the long side and the short side of the main board in order to protect the corresponding region on the main board. In one embodiment, buffer layer 20 includes: a first buffer unit 21 and a second buffer unit 22.

Either buffer unit 21, 22 includes: silica gel buffer chip intermediate level and combine in the AB double faced adhesive tape of silica gel buffer chip intermediate level both sides. Therefore, the bonding force between the main board and the main board can be increased by adopting the AB double-sided adhesive tape. In one embodiment, the silicone cushion sheet may be a type QX-030T1B-BF80-520P silicone cushion sheet.
Wherein, AB double faced adhesive tape includes: the adhesive comprises a polyester film middle layer, silica gel combined on one side of the polyester film middle layer and a silica gel combined on the other side of the polyester film middle layer. In one embodiment, the AB double-sided adhesive tape can be 3M 9119-50.
Based on the same inventive concept, another embodiment of the present invention further provides an insulating sheet roll, wherein the wave-absorbing insulating sheet 100 is packaged in the roll at intervals.

A rectangular second supporting block 2013 is disposed at the right side of the receiving cavity 2011, and the second supporting block 2013 can correspondingly support the right edge area of the wave-absorbing insulation sheet 100.
The lower end of the housing cavity 2011 is provided with a rectangular third supporting block 2014, and the rear end of the third supporting block 2014 is further provided with an extending portion extending inwards, and the third supporting block 2014 can correspondingly support the lower side edge region of the wave-absorbing insulation sheet 100.
In addition, the height of each supporting block is greater than the height of the buffer layer 20 and the first and second adhesive layers 30 and 40. Therefore, the surfaces of the buffer layer 20, the first adhesive layer 30 and the second adhesive layer 40 at the same height can be prevented from contacting the bottom surface of the accommodating cavity 2011, and a certain protection effect is achieved.
In order to prevent the wave-absorbing insulating sheet 100 packaged in the containing cavity 2011 from falling, the two side edges of the protective film 202 are bonded to the areas on the two sides of the containing cavity 2011 through adhesives. Therefore, the wave-absorbing insulating sheet 100 is conveniently packaged in the corresponding containing cavity 2011, and when the protective film 202 is peeled off, the adhesive is only arranged on the edges of the two sides, so that the wave-absorbing insulating sheet 100 in the containing cavity 2011 cannot be taken up.
