Description

Technical Field

[0001] This utility model relates to the field of hot melt adhesive film technology, specifically to an anti-corrosion hot melt adhesive film. Background Technology

[0002] Hot melt adhesive film is a type of film product with or without release paper. It can be easily used for continuous or intermittent operation and is widely used for bonding and manufacturing various clothing fabrics, paper, polymer materials and metals. It can also achieve good results when bonding uneven surfaces. It is mainly used for bonding and fixing objects on both sides. As market demand for components becomes more stringent, the variety of hot melt adhesive films has begun to increase.

[0003] For example, Chinese Patent (Publication No.: CN221397783U) discloses an antistatic hot melt adhesive film, comprising an antistatic fiber layer, a first hot melt adhesive film layer, a conductive metal layer, a second hot melt adhesive film layer, a polyethylene fiber substrate layer, a polyester layer, a third hot melt adhesive film layer, and release paper arranged sequentially. The polyester layer is made of polyurethane material, and multiple evenly distributed slots are provided on the bottom surface of the polyester layer. The conductive metal layer is a mesh structure layer woven from metal fibers, and the antistatic fiber layer is woven from metal fibers and polyester fibers. In this utility model, the combined effect of the conductive fiber layer and the antistatic fiber layer effectively improves the overall antistatic capability of the hot melt adhesive film. It considers the use of hot melt adhesive film and polyethylene fiber. At the same time, the multiple slots on the polyester layer allow the third hot melt adhesive film layer to form a matching block when coated onto the polyester layer, thereby improving the adhesion between the hot melt adhesive layer and the polyester layer and increasing the service life of the hot melt adhesive film.

[0004] However, the corrosion resistance of this hot melt adhesive film is not good enough. This hot melt adhesive film only relies on the corrosion resistance of the hot melt adhesive film itself to achieve corrosion resistance, and it is difficult to actively prevent corrosion. Therefore, a corrosion-resistant hot melt adhesive film is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a corrosion-resistant hot melt adhesive film with advantages such as good corrosion resistance, thus solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a corrosion-resistant hot melt adhesive film, comprising a base, two side plates fixed to the top of the base, a rotating shaft rotatably connected to the opposite side of the two side plates via bearings, a hot melt adhesive film body wrapped around the outer surface of the rotating shaft, and a cutting component provided on the top of the base and on the right side of the hot melt adhesive film body.

[0011] Furthermore, the anode layer is zinc powder modified epoxy resin, the skeleton layer is glass fiber mesh, the adhesive layer is a mixture of butyl rubber and polyester resin, and the protective layer is matte release paper.

[0014] Furthermore, a groove is provided on the top of the connecting platform, and the groove is adapted to the cutting blade.

[0015] Compared with the prior art, this utility model provides a corrosion-resistant hot melt adhesive film, which has the following beneficial effects:

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 4 In this embodiment, a corrosion-resistant hot melt adhesive film includes a base 1. Two side plates 2 are fixed on the top of the base 1. A rotating shaft 3 is rotatably connected to the opposite side of the two side plates 2 via a bearing. A hot melt adhesive film body 4 is wrapped around the outer surface of the rotating shaft 3. A cutting component 5 is provided on the top of the base 1 and on the right side of the hot melt adhesive film body 4.

[0026] In addition, the hot melt adhesive film body 4 is composed of a surface layer 401, a reinforcing layer 402 and a protective layer 403. The surface layer 401 is mainly used to provide waterproof and wear-resistant properties. The reinforcing layer 402 is provided on the inner side of the surface layer 401. The reinforcing layer 402 can improve the mechanical properties of the hot melt adhesive film body 4. The inner side of the reinforcing layer 402 is fixed to the protective layer 403.

[0027] It should be further explained that the surface layer 401 includes a wear-resistant layer 4011, and a plurality of wear-resistant particles 4013 are fixed on the outer side of the wear-resistant layer 4011. The wear-resistant particles 4013 can further improve the wear resistance of the hot melt adhesive film body 4. When the surface of the hot melt adhesive film is rubbed, it will first come into contact with the wear-resistant particles 4013 on the surface. When the external force is too large, the wear-resistant particles 4013 can reduce the damage to the wear-resistant layer 4011 by falling off. A waterproof layer 4012 is fixed on the inner side of the wear-resistant layer 4011.

[0028] It is known that the wear-resistant layer 4011 is polyamide and the waterproof layer 4012 is fluorocarbon coating. Polyamide has good temperature resistance and high wear resistance, while fluorocarbon coating can resist ultraviolet aging, strong acids, strong alkalis and salt spray, and has a service life of more than 20 years and good waterproof performance.

[0029] In addition, the reinforcing layer 402 includes an anode layer 4021 fixed to the inside of the waterproof layer 4012, an inherent skeleton layer 4022 inside the anode layer 4021, the anode layer 4021 can perform active corrosion protection, the skeleton layer 4022 can improve the overall comprehensive mechanical properties, and an adhesive layer 4023 is fixed to the inside of the skeleton layer 4022, and the skeleton layer 4022 is fixed to the protective layer 403 through the adhesive layer 4023.

[0030] It is known that the anode layer 4021 is zinc-modified epoxy resin. Zinc preferentially corrodes to protect the iron substrate. Even if the coating is partially damaged, it can delay the spread of rust. After curing, the epoxy resin forms a dense network structure with strong adhesion. The skeleton layer 4022 is a glass fiber mesh cloth. Through the warp and weft weave structure, it provides high tensile strength and impact resistance, effectively disperses stress, and prevents the hot melt adhesive film from cracking due to temperature changes or external impacts. It is alkali-resistant, acid-resistant, and cement-resistant, with excellent chemical stability and high temperature resistance up to 250℃, making it suitable for high-temperature environments. The adhesive layer 4023 is a mixture of butyl rubber and polyester resin, and the protective layer 403 is a matte release paper. When using it, you only need to peel off the matte release paper, and under the action of the adhesive layer 4023, the hot melt adhesive film body 4 can be quickly pasted onto the surface of the object.

[0031] In this embodiment, butyl rubber has extremely low gas permeability, effectively blocking the penetration of media such as water vapor and oxygen, while polyester resin has strong weather resistance. Through the action of butyl rubber and polyester resin, a good bonding effect can be ensured.

[0032] Please refer to it again. Figure 1 and Figure 5To facilitate cutting, the cutting assembly 5 in this embodiment includes a fixed connecting platform 501 to the top of the base 1. Two support plates 502 are fixed to the top of the connecting platform 501. The two support plates 502 can provide stable support for the protective shell 503. The protective shell 503 is fixed to the top of the two support plates 502. The protective shell 503 can provide support for the cutting part 504. The inner side of the protective shell 503 is provided with a cutting part 504 that penetrates the protective shell 503.

[0033] Furthermore, the cutting section 504 includes a cutting blade 5041 that penetrates the protective shell 503. Ear plates 5042 are fixed on both sides of the cutting blade 5041 and inside the protective shell 503. When the cutting blade 5041 moves downward, the ear plates 5042 will cause multiple connecting springs 5043 to compress. When the external force disappears, the connecting springs 5043 will cause the cutting blade 5041 to move upward, which is convenient for subsequent use. Multiple connecting springs 5043 are fixed at the bottom of each ear plate 5042. The bottom of the multiple connecting springs 5043 is fixed to the inner bottom wall of the protective shell 503. The top of the connecting platform 501 is provided with a groove that is adapted to the cutting blade 5041.

[0034] In this embodiment, the hot melt adhesive film body 4 can be smoothly cut by the groove and the cutting blade 5041, and a large shearing force can be provided by the groove and the cutting blade 5041.

[0035] Understandably, the surface layer 401 and the reinforcing layer 402 can ensure both good mechanical properties and good corrosion resistance. In addition, the hot melt adhesive film body 4 can be cut smoothly through the cutting component 5.

[0036] All electrical components mentioned in this article are electrically connected to the controller and power supply. The control method of this utility model is controlled by the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0037] The working principle of the above embodiments is as follows:

[0038] In use, first pull out the hot melt adhesive film body 4 and make it pass through the cutting assembly 5. After pulling it out to the required length, press the cutting blade 5041 to make it cut the hot melt adhesive film body 4. After cutting, the cutting blade 5041 returns to its original position under the action of the connecting spring 5043 and the ear plate 5042. When the surface of the hot melt adhesive film body 4 encounters corrosive liquids, such as salt water, the waterproof layer 4012 will first block most of the liquid. The liquid that passes through the waterproof layer 4012 can effectively delay corrosion under the action of the anode layer 4021.
