Description

Technical Field

[0001] The utility model relates to the technical field of heat-resistant adhesive tapes, in particular to a high-strength heat-resistant adhesive tape. Background Art

[0002] Tape is composed of two parts: a base material and an adhesive. It connects two or more unconnected objects together through bonding. A layer of adhesive is coated on its surface. The earliest adhesives came from animals and plants. In the 19th century, rubber was the main component of adhesives, while various polymers are widely used in modern times. Adhesives can stick to things because bonds are formed between their own molecules and the molecules of the objects to be connected. This bond can firmly bond the molecules together.

[0003] Most existing adhesive tapes are wound together in rolls. Since adhesive residue is very likely to remain on the edge of the tape, the edge of the rolled tape has a larger area and is easily sticky with a lot of dust. If there is a lot of dust and dirt on the edge of the tape, it may cause the tape to peel or tear during use, reducing the reliability and durability of the tape. Therefore, the utility model provides a high-strength heat-resistant tape to solve the problems raised in the above background technology. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art and to propose a high-strength temperature-resistant tape. The tape is provided with extended edges on the edges of both sides of the tape body to shield the edges, so as to prevent dust from sticking to the edges of the tape and affecting the aesthetics of the tape. Even when a large amount of dust accumulates for a long time, it may cause the tape to peel off or tear during use. The durability of the tape is improved.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A high-strength heat-resistant adhesive tape, comprising an adhesive tape body and a reel, wherein a vertical tear hole is provided in the middle of the upper end surface of the adhesive tape body, a plurality of groups of transverse tear holes are provided on the upper end surface of the adhesive tape body, a double-sided release paper is adhered to the lower end of the adhesive tape body, and an extension edge is fixedly provided on both sides of the double-sided release paper;

[0007] The tape body comprises a base layer, a high temperature resistant layer is fixedly arranged on the upper end of the base layer, a reinforcement layer is fixedly arranged on the upper end of the high temperature resistant layer, and a wear-resistant layer is fixedly arranged on the upper end of the reinforcement layer;

[0008] Through the above technical scheme, the edges of both sides of the tape are protected by setting extended edges to prevent residual glue from sticking to dust and reducing the durability of the tape. Two types of easy-to-tear holes, horizontal and vertical, are set to facilitate cutting the tape according to needs without the need to use scissors, making it more flexible and convenient to use. The durability of the tape can be improved by setting a high temperature resistant layer, a reinforcement layer and a wear-resistant layer on the surface of the tape.

[0009] Furthermore, a second adhesive layer is fixedly provided at the lower end of the base layer, and a first adhesive layer is fixedly provided at the upper ends of the two extending edges;

[0010] Through the above technical solution, by setting the second adhesive layer on the lower side of the base layer to adhere the tape body to the surface of various objects, and by setting the first adhesive layer on the upper end of the extended edge, the tape body can be adhered together to avoid unraveling when it is wound.

[0011] Furthermore, the first glue layer and the second glue layer are both set to acrylic resin;

[0012] Through the above technical scheme, acrylic resin achieves a good balance between adhesion and tearability, making it an ideal choice for tapes for various purposes, with good adhesion and the ability to effectively bond to various surfaces, including paper, plastic, metal and wood.

[0013] Furthermore, the high temperature resistant layer is provided as a polyimide coating;

[0014] Through the above technical solution, polyimide is a high-performance polymer with excellent high temperature resistance and chemical stability, and also has good corrosion resistance, wear resistance and fatigue resistance.

[0015] Further, the reinforcement layer is provided as a glass fiber coating;

[0016] Through the above technical solution, the glass fiber coating can increase the tensile strength and tear resistance of the tape. The glass fiber has excellent strength and stiffness, and can effectively enhance the structural strength of the tape, making it more suitable for applications that need to withstand greater tensile and tearing forces.

[0017] Further, the wear-resistant layer is configured as a chloroprene rubber coating;

[0018] Through the above technical solution, the chloroprene rubber coating has good wear resistance and weather resistance.

[0019] Furthermore, the tape body is wound around the reel;

[0020] Through the above technical solution, the tape can be easily stored and organized by winding the tape body around the reel.

[0021] The utility model has the following beneficial effects:

[0022] 1. The utility model proposes a high-strength heat-resistant tape. Since the residual glue on both sides of the tape body sticks to dust, the two sides of the tape become dirty, especially the rolled tape has a larger side area and too much residual glue and more stains, so the stains will be more obvious. The device arranges double-sided release paper on the lower side of the tape body, adheres the tape body to the upper side of the double-sided release paper, and extended edges are arranged on both sides of the release paper. The two sides of the tape body are shielded by the extended edges to prevent the residual glue on the edge of the tape from sticking to dust, thereby improving the durability of the tape.

[0023] 2. The utility model proposes a high-strength temperature-resistant adhesive tape, which is provided with two kinds of easy-tear holes, namely, horizontal and vertical, on the surface of the adhesive tape. Most of the existing ones do not have or only have horizontal easy-tear holes. Since the adhesive tape is relatively wide, it is inconvenient to use scissors to cut it when used in some narrow places. The utility model provides a vertical easy-tear hole and multiple horizontal easy-tear holes in the middle of the adhesive tape, so that the size of the adhesive tape can be flexibly changed, which is more convenient to use. In addition, a reinforcing layer and a wear-resistant layer are provided on the surface of the adhesive tape, which can improve the strength and wear resistance of the adhesive tape, thereby improving the durability of the adhesive tape.

[0033] By setting the vertical easy-tear holes 3, the wider tape body 1 can be torn into two narrower ones, which is convenient for pasting in narrow places. By setting multiple groups of horizontal easy-tear holes 5, it is convenient for the tape body 1 to be torn for pasting. By setting the double-sided release paper 6, silicone oil is provided on both sides of the release paper, so that the upper side of the double-sided release paper 6 and the second adhesive layer 102 on the lower side of the tape body 1 are adhered, and the lower side and the first adhesive layer 7 on the upper side of the extended edge 4 are adhered.

[0034] The tape body 1 comprises a base layer 101 , a high temperature resistant layer 103 is fixedly disposed on the upper end of the base layer 101 , a reinforcement layer 104 is fixedly disposed on the upper end of the high temperature resistant layer 103 , and a wear-resistant layer 105 is fixedly disposed on the upper end of the reinforcement layer 104 .
