Description

Technical Field

[0001] The utility model relates to the technical field of acrylic protective film tapes, in particular to an acrylic protective film tape with a multi-layer adhesion structure. Background Art

[0002] Acrylic protective film tapes are mainly made of all-acrylic materials. This material not only provides good mechanical properties but also endows the tape with strong adhesion. This enables the tape to firmly adhere to various surfaces, including plastics, metals, woods, and papers, etc., and can maintain good adhesion even on complex or curved surfaces. Its unique adhesion performance makes it widely used in construction, electronic product manufacturing, and the automotive industry.

[0003] However, in the prior art, some acrylic protective film tapes are difficult to effectively dissipate the moisture generated by temperature changes in high-temperature and humid environments. Condensed water will form on the adhesive surface when it gets cold, resulting in unstable adhesive performance. Therefore, an acrylic protective film tape with a multi-layer adhesion structure is proposed to solve the above problems. Summary of the Utility Model

[0004] In order to make up for the above deficiencies, the utility model provides an acrylic protective film tape with a multi-layer adhesion structure, aiming to improve the problem that in the prior art, it is difficult to effectively dissipate the moisture generated by temperature changes in high-temperature and humid environments, resulting in unstable adhesive performance.

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Refer to Figure 1 - Figure 3 , an embodiment provided by the present utility model: an acrylic protective film tape with a multi-layer adhesion structure, including a base 1, and a plurality of reinforcing ribs 2 are fixedly connected inside the base 1. The base 1 serves as the foundation of the entire protective film tape, and a plurality of reinforcing ribs 2 are fixedly connected inside it. These reinforcing ribs 2 not only enhance the mechanical strength of the base 1, but also provide good tensile and compressive properties, ensuring the integrity of the shape and structure during pasting, tearing, or use. The reinforcing ribs 2 maintain the strength and rigidity of the protective film 7 like a skeleton, preventing bending or distortion. A waterproof sheet 3 is fixedly connected to the top end of the base 1. The waterproof sheet 3 is a sealing layer, whose function is to block the penetration of moisture and protect the underlying layers from water damage. A plurality of water guide grooves 4 are opened at the top end of the waterproof sheet 3. The water guide grooves 4 are arranged in different patterns and densities to maximize the collection and guiding efficiency of moisture. A breathable film 5 is fixedly connected to the top end of the waterproof sheet 3. An air permeable component for air exchange is arranged inside the breathable film 5. The air permeable component can prevent the surface of the object to be protected from generating condensate due to airtightness, and can also discharge the internal moisture to keep the object to be protected in a dry state. A protective film 7 is fixedly connected to the top end of the breathable film 5. The protective film 7 is used to protect the underlying layers from dust, scratches, and other physical damages. An adhesion layer 8 is fixedly connected to the bottom end of the base 1. The adhesion layer ensures that the entire structure can be firmly pasted on various surfaces, which can not only ensure the close fit between the protective film and the surface of the object to be protected, but also leave no residual glue, ensuring the aesthetics and practicality during use. Tear strips 9 are respectively fixedly connected to the front and rear sides of the protective film 7. The tear strips 9 are used to facilitate the tearing of the tape. Users can easily tear the protective film from either end without additional tools, greatly improving the user experience.

[0032] Refer to Figure 4, the ventilation component includes a ventilation membrane 5. A plurality of honeycomb holes 6 are formed inside the ventilation membrane 5. The function of the ventilation membrane 5 is to allow air to pass through freely, thereby balancing the air pressure inside and outside the protective film and avoiding the phenomena of blistering or peeling caused by the air pressure difference due to the closed environment. The shape and arrangement of the honeycomb holes 6 are designed to maximize the ventilation efficiency while maintaining the integrity and strength of the material. The design inspiration for the honeycomb holes 6 comes from the nest structure of bees in nature. This hexagonal arrangement can effectively disperse pressure and increase the stability and durability of the ventilation membrane 5.

[0033] Refer to Figure 2 , the base 1 is made of polyethylene terephthalate. The base 1 is the infrastructure of the whole structure and is made of PET material. PET is a polymer with heat resistance, cold resistance, corrosion resistance and high transparency. The waterproof sheet 3 is made of polyurethane. The waterproof sheet 3 can not only effectively block the penetration of moisture and other liquids, but also has sufficient flexibility to adapt to the shape and size changes of the base 1. The ventilation membrane 5 is made of silica gel. The ventilation membrane 5 can keep the inside dry under changing environmental pressures, prevent the formation of condensed water droplets due to the temperature difference inside and outside, and can allow air to pass through while blocking the entry of water vapor and other liquids. The protective film 7 is made of polyethylene. The protective film 7 provides an additional physical barrier against scratches, dust and other minor abrasions, and has good chemical resistance and water resistance, which can provide an additional protective layer. The adhesive layer 8 is made of an optically transparent adhesive. The adhesive layer 8 not only provides strong adhesion, but also ensures high light transmittance and clear visual effects at the interface. The optically transparent adhesive can provide strong adhesion without losing transparency, ensuring that the protective film fits tightly with the surface to be protected. The adjacent sides of the two tear strips 9 are respectively fixedly connected to the front and back sides of the protective film 7. The tear strips 9 are used to facilitate the tearing of the tape during use. The outside of a plurality of reinforcing ribs 2 is fixedly connected to the inner wall of the base 1. The reinforcing ribs 2 provide additional strength and stability and enhance the durability of the overall structure.

[0034] Working principle: When in use, first, confirm that the surface to be protected is clean, free of oil stains and dust. Pull out the film tape of the required length from the reel. The staff pulls the tear strip 9, then contacts the tape with the object, and finally presses the protective film 7. The protective film 7 applies pressure to the breathable film 5, and the breathable film 5 drives the honeycomb holes 6 and the base 1 to move towards the object, so that the adhesive layer 8 is tightly adhered to the object. The water vapor generated by the tape in high-temperature and humid environments is gathered through the water guide groove 4 and drained out, so that the tape quickly removes the moisture on the surface, preventing the moisture from staying between the tape and the pasting surface for a long time. This can reduce the tape falling off or the adhesion decreasing caused by moisture penetration, effectively guide rainwater and condensed water to quickly flow to the drain outlet, thus avoiding the accumulation of moisture on the tape surface and improving the drainage efficiency. This is crucial for keeping the building surface dry and clean, especially in rainy seasons or humid environments.

[0035] At high temperatures, heat is generated at the adhesion point between the tape and the object. The heat generated can be dissipated through the honeycomb holes 6 on the breathable film 5. Thus, during the long-term pasting process of the tape, by allowing gas exchange, the air permeability reduces the air pressure difference caused by temperature changes, thereby reducing the problems of the tape lifting or falling off due to air pressure. At the same time, it enables the tape to distribute the adhesive force more evenly, thus improving its protective effect on the surface. This protects the surface from dust, water vapor and chemical substances.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
