Description

Technical Field

[0001] This utility model belongs to the field of adhesive tape technology, specifically, it relates to a high-temperature resistant adhesive tape structure. Background Technology

[0002] In industrial settings such as electronic packaging, automobile manufacturing, and high-temperature equipment maintenance, high-temperature resistant tapes are commonly used for bonding and fixing components, surface protection, and heat insulation. They are important auxiliary materials for ensuring stable operation and safe operation of equipment in high-temperature environments, and their performance directly affects production efficiency and protective effect.

[0003] When using it, it was found that the high-temperature resistant tape was difficult to tear by hand, and the cut surface was easily crooked when torn, which affected its use. When used in long sizes, the adhesive layer was prone to self-adhesion or contamination with impurities, and the edge protection of the tape was insufficient.

[0004] In view of this, this utility model is hereby proposed. Utility Model Content

[0005] To address the problems of high-temperature resistant tape being difficult to tear by hand, prone to producing skewed cuts that affect its use, easily self-adhesive or attracting impurities when used in long applications, and having insufficient edge protection, the basic concept of this utility model is as follows:

[0006] A high-temperature resistant tape structure includes a tape body and release paper. The tape body includes an abrasion-resistant surface layer, a high-temperature resistant heat insulation layer, and a high-temperature resistant adhesive layer. The tape body is sequentially composited from the abrasion-resistant surface layer, the high-temperature resistant heat insulation layer, and the high-temperature resistant adhesive layer. The release paper is adhered to the bottom of the high-temperature resistant adhesive layer. A V-shaped opening is uniformly provided on one side of the tape body along its length. The release paper has a segmented structure along its length, and release paper gaps are provided at the corresponding V-shaped openings and between adjacent V-shaped openings. Anti-slip protrusions are provided on the abrasion-resistant surface layer on both sides of the V-shaped openings. The tape body has a differentiated structure that is thicker in the middle and thinner on both sides along its width. The release paper at the bottom position of the V-shaped opening is provided with an easy-tear corner.

[0007] In a preferred embodiment of this utility model, the wear-resistant surface layer is made of polyimide, the high-temperature resistant heat insulation layer is made of ceramic fiber and organosilicon composite material, and the high-temperature resistant adhesive layer is made of organosilicon pressure-sensitive adhesive material. The wear-resistant surface layer, the high-temperature resistant heat insulation layer and the high-temperature resistant adhesive layer are fixedly connected from the outside to the inside.

[0008] In a preferred embodiment of this utility model, the release paper is a silicone oil-coated PET release film, and the tear-off corner is a raised structure extending outward from the bottom of the V-shaped opening of the release paper.

[0009] In a preferred embodiment of this utility model, the opening angle of the V-shaped opening is 60°.

[0010] In a preferred embodiment of this utility model, the anti-slip protrusion is integrally formed with the wear-resistant surface layer and is made of polyimide. The anti-slip protrusion is arranged along the width direction of the tape body and corresponds to the V-shaped opening. The protrusion height is 0.03mm and the length covers a 1cm area on each side of the V-shaped opening.

[0011] In a preferred embodiment of this utility model, the middle area of ​​the tape body and the two side edge areas are provided with a thickness difference, the middle area is 0.02-0.03mm thick, and the two side edges of the wear-resistant surface layer have an inward turning structure towards the high-temperature resistant adhesive layer.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] This utility model achieves quick tearing through the combination of V-shaped opening and anti-slip protrusion, ensuring neat edges. The segmented release paper with easy-tear corner design can be peeled off segment by segment, avoiding self-adhesion or contamination of the adhesive layer. The differentiated structure of the adhesive tape, which is thick in the middle and thin on both sides, and the inward folding of the edges, prevents the edges from curling up and protects the sides. The three-layer high-temperature resistant composite structure works together to achieve wear resistance, heat insulation, and stable adhesion.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0021] like Figures 1 to 3As shown, a high-temperature resistant tape structure includes a tape body and a release paper 4. The tape body includes a wear-resistant surface layer 1, a high-temperature resistant heat insulation layer 2, and a high-temperature resistant adhesive layer 3. The tape body is composed of the wear-resistant surface layer 1, the high-temperature resistant heat insulation layer 2, and the high-temperature resistant adhesive layer 3 in sequence. The release paper 4 is attached to the bottom of the high-temperature resistant adhesive layer 3. V-shaped openings 5 ​​are uniformly provided on one side of the tape body along the length direction. The release paper 4 has a segmented structure along the length direction, and release paper gaps 7 are provided at the corresponding V-shaped openings 5 ​​and between adjacent V-shaped openings 5. Anti-slip protrusions 6 are provided on the wear-resistant surface layer 1 on both sides of the V-shaped openings 5. The tape body has a differentiated structure that is thicker in the middle and thinner on both sides along the width direction. The release paper 4 at the bottom of the V-shaped openings 5 ​​is provided with easy-tear corners 8. In this design, a three-layer composite structure ensures high-temperature resistance, while V-shaped opening 5 and anti-slip protrusion 6 enable quick tearing. Segmented release paper 4 and easy-tear corner 8 facilitate segmented operation and prevent sticking. The structure design, which is thick in the middle and thin on both sides, reduces edge folding, thus balancing ease of use and structural stability.

[0022] like Figures 1 to 3 As shown, in a specific embodiment, the wear-resistant surface layer 1 is made of polyimide, the high-temperature resistant insulation layer 2 is made of a composite material of ceramic fiber and silicone, and the high-temperature resistant adhesive layer 3 is made of silicone pressure-sensitive adhesive. The wear-resistant surface layer 1, the high-temperature resistant insulation layer 2, and the high-temperature resistant adhesive layer 3 are sequentially fixedly connected from the outside to the inside. In this configuration, the three layers respectively endow the tape with the core properties of wear resistance, heat insulation, and high-temperature adhesion, ensuring stable operation in high-temperature environments.

[0023] like Figures 1 to 3 As shown, the release paper 4 is further made of silicone oil-coated PET release film, and the easy-tear corner 8 is a raised structure extending outward from the bottom of the V-shaped opening 5 of the release paper 4. In this configuration, the silicone oil-coated release paper 4 reduces the adhesion to the high-temperature resistant adhesive layer 3, while the easy-tear corner 8 provides a convenient force point for peeling off the release paper 4, improving operational efficiency.

[0024] like Figures 1 to 3 As shown, the opening angle of the V-shaped opening 5 is 60°. In this configuration, the V-shaped opening 5 provides a reasonable weak point for tearing by hand, balancing the ease of tearing with the structural stability of the tape itself.

[0025] like Figures 1 to 3 As shown, the anti-slip protrusion 6 is integrally formed with the wear-resistant surface layer 1 and is made of polyimide. The anti-slip protrusion 6 is set along the width direction of the tape body and corresponds to the V-shaped opening 5, with a protrusion height of 0.03mm and a length covering a 1cm area on each side of the V-shaped opening 5. In this configuration, the integrally formed anti-slip protrusion 6 enhances the friction during tearing and guides the tearing direction through physical limiting, preventing the cut surface from being skewed.

[0026] like Figures 1 to 3As shown, furthermore, the middle area and the two side edge areas of the tape body have a thickness difference, with the middle area being 0.02-0.03 mm thick, and the two side edges of the wear-resistant surface layer 1 having an inward folding structure towards the high-temperature resistant adhesive layer 3. In this configuration, the differential thickness and the inward folding structure of the edges reduce edge curling, while simultaneously protecting the high-temperature resistant adhesive layer 3 on the sides.

[0027] The implementation principle of a high-temperature resistant tape structure in this embodiment is as follows: Through the design of a three-layer composite main body and functional auxiliary structures, a comprehensive optimization of high-temperature resistance and ease of use is achieved. The tape body is sequentially composed of an outer polyimide wear-resistant surface layer 1, a middle ceramic fiber and silicone composite high-temperature resistant heat insulation layer 2, and an inner silicone pressure-sensitive adhesive high-temperature resistant layer 3. After the three layers are fixedly connected, they form an integral structure with wear resistance, heat insulation, and stable adhesion. The release paper 4 is a silicone oil-coated PET release film, adhered to the bottom of the high-temperature resistant adhesive layer 3, and naturally segmented along its length through the release paper gaps 7. The segmentation positions cover the V-shaped openings 5 ​​evenly distributed on one side of the tape body and the spaces between adjacent V-shaped openings. The V-shaped openings 5 ​​are 60° openings. The release paper at the bottom of the tape extends outward to form an easy-tear angle 8, which facilitates peeling off the release paper segment by segment and avoids self-adhesion or contamination of the adhesive layer after exposure when using long tapes. The wear-resistant surface layer 1 on both sides of the V-shaped opening 5 is provided with polyimide anti-slip protrusions 6 integrally formed with the surface layer. The protrusions are 0.03mm high and cover an area of ​​1cm on each side of the opening. While providing friction when tearing, they also guide the tearing direction through physical limiting to prevent the cross-section from being skewed. The tape body has a differentiated structure along the width direction, which is thicker in the middle and thinner on both sides. The middle area is 0.02-0.03mm thicker than the edge areas on both sides. The thickened middle area ensures the heat insulation effect, while the thin edges on both sides, together with the inward folding structure of the wear-resistant surface layer 1 towards the adhesive layer, reduce edge curling and warping.
